Crowcon XgardIQ Fixed Gas Detector
The Crowcon XgardIQ is the next generation of fixed gas detectors from Crowcon and has been manufactured to enhance site safety and minimise the time workers must spend in hazardous areas exposed to harmful gases.
The fixed gas detector is versatile, compatible with Crowcon’s full range of sensor technologies and is available fitted with a variety of flammable, toxic or oxygen gas sensors.
Andy Avenell, Senior Business development manager at Crowcon, said while explaining the product development;
“We spend a significant amount of time talking to engineers and operators in oil and gas facilities, petrochemical and chemical plants and other high risk areas. The experiences and insight gained from such sites has been instrumental in the specification development of Crowcon XgardIQ.”
When lives and real estate are at stake, the Crowcon XgardIQ provides reliable notification system of the presence of harmful, explosive and flammable gases. This minimises the amount of time that a worker must spend in a hazardous area.
The XgardIQ minimises the amount of time spent between swapping sensors and performing routine maintenance. The gas detecting sensors can be ‘hot-swapped’ without the need for a hot work permit. The old module can be replaced with a new pre-calibrated one or removed for testing and calibration in a safe area.
The modern plant environments often require a varying degree of gas detection diversification. The Crowcon XgardIQ can offer this versatility and wide application of gas detection with a single product.
Crowcon’s unique positive safety feature reassures operators that the XgardIQ is functioning properly by alerting when there are any irregular events that may effect the sensors performance. This puts the XgardIQ ahead of other sensors that may otherwise cease to function when exposed to extreme environmental conditions.
The XgardIQ is compatible with virtually any control system including gas detection panels, PLC’s, DCS’s and SCADA systems. This makes the detector easier to install and reduces costs associated with installation.
When calibrating the XgardIQ sensor, calibration gas must be applied used the calibration cap also available from Crowcon. Typically, a flow rate of 0.5 litres per minuter is appropriate however this may vary for different sensor types.
Calibration can be performed with a suitable gas concentration from 10% of the scaled sensor range to 100% of the maximum sensor range. The minimum calibration gas concentration that can be used is 10% of the scaled range.
Hazardous area industries including offshore oil/gas platforms and FPSOs, onshore oil refineries, processing plants, pipelines, storage farms and LPG/LNG plants all utilise or produce a wide range of hazardous flammable liquids and gases that can be detected using correctly specified flame and gas detectors.
Detecting toxic and flammable gases requires the detectors to be classified and certified according to the specific IECEx or ATEX standard – we distribute flame and fire detectors manufactured by Spectrex to operate in the harshest environmental conditions including self-contained stand-alone devices designed for direct connection to control and alarm systems or automatic fire extinguishing systems.
Our range of Hazardous Area Fire & Gas Detection System products also includes Explosion Proof Warning Systems & Hazardous Area Lighting – comprehensive range of intrinsically safe, flameproof and explosion proof alarm sounders, sirens, bells and horns, loudspeakers and beacons.

Exposure to hydrogen sulphide (H₂S) gas is a serious risk to people, even at low levels.
Portable gas detectors and fixed gas detectors from leading manufacturers such as Crowcon and Drager, provide a gas monitoring solution alerting the worker to the danger and preventing accidents or even death.
Hydrogen sulphide gas (H₂S) has a very distinctive smell – everyone has experienced the rancid stink bomb or rotten egg smell at some point.
H₂S can be a man made by-product and is commonly found in the refining of crude oil and the processing of “soured” natural gas. Other names for H2S include sewer gas, stink damp, swamp gas and manure gas.
The gas is also a by-product of the bio degeneration of organic matter posing a particularly high risk to those working
in the sewage treatment industry.
H₂S can be deadly if workers are exposed to certain concentrations of the gas – it is not an option to rely on a person’s sense of smell when it comes to Health & Safety and the protection of life.
This is why portable and fixed gas detectors are used to protect people from the risk.
In one incident, three workers lost their lives whilst working on an oil transfer line in a corrosion coupon pit. A 4th worker was critically injured and air lifted to hospital – the cause of death was cited as exposure to a lethal concentration of H₂S gas.
H₂S is a flammable gas when in high concentrations. However this is not the main danger. Just like CO₂, it is a toxic gas and poses a risk even at low exposure levels:-
Ironically, one of the side effects of exposure to H₂S gas is depletion of the sense of smell meaning workers exposed to the gas may inadvertently continue to work despite initially being exposed to the “rotten egg” smell.
H₂S is heavier than air and therefore will sink to the floor meaning working in confined spaces like shafts or trenches is particularly dangerous.
Workers can be exposed to hydrogen sulphide gas in numerous process industries including mining, paper mills, iron smelting, petroleum refining and sewage treatment works.
Even low concentration levels of H₂S can be toxic if individuals are subjected to the gas for an extended period of time leading to fatigue, pulmonary edema, loss of consciousness and even death.
Occupational exposure to hydrogen sulphide typically occurs in oil, gas and petrochemical industries as the by-product of coke (blast-furnacing).
The warning signs of H2S exposure are easy to recognise with many parts of the body being affected. Eye irritation will occur with physical soreness, light sensitivity and pain experienced when viewing or looking towards a bright light; commonly known as ‘Gas Eye’.
Other symptoms include breathing irritation such as sore naval passages, a burning sensation on the lungs, headaches, confusion and nausea. The real danger with H2S is that it can kill at reasonable low levels.
Hydrogen sulphide is considered a broad spectrum poison and as such it can poison several systems in the body, however the most severely affected are the nervous and respiratory. 
In addition to being toxic, H2S is highly flammable and therefore presents an extra risk in the offshore environment.
The gas is heavier than air and tends to accumulate in low lying areas, rapidly destroying the sense of smell which would be a first stage indicator of the presence of H2S. Hydrogen sulphide is toxic at breathable concentrations between 500-1000ppm however death is not instantaneous.
At concentrations of 1000ppm and above however, the lethal effects are much more instant as this causes strong stimulation of the central nervous system and rapid breathing, leading to a total loss of breathing.
The Health & Safety Executive (HSE) states that 800ppm is the generally accepted lethal concentration for 50% of an exposed human population for 5 minutes exposure to hydrogen sulphide gas. On an offshore installation, standards recommend a 3 tier approach to gas detection that are similar to the flammable hazardous area classification arrangements.
Category 0 – Areas where H2S will be present during normal working operations, such as confined spaces or vessels.
Category 1 – Areas in which H2S may be encountered during normal working operations. Entry is only allowed with a portable gas detector and fixed gas detection is recommended.
Category 2 – Areas which are free from H2S during normal operations but could be contaminated by a gas leak or equipment malfunction.
Gas detection installations in offshore environments typically operate with an alarm and action at least 20% and 50-60% LEL however some duty holders will operate their hydrocarbon detection systems at 10% and 25% LEL to provide a more sensitive system – it is recommended to operate hydrocarbon gas detection systems at the more sensitive values.
Crowcon X-Gard provides a fixed gas detection solution in the offshore oil and gas industry.
Fixed gas detectors for H₂S are suitable for larger areas such as plant rooms where numerous detectors can be networked to a master control panel. In the event of H₂S reaching the preset exposure limit, visual and audible alarms will activate to alert the workforce to the danger.
The Crowcon Xgard and the Crowcon TXgard Plus can both be used for H₂S gas detection and offer a fixed, permanent detection solution.
Portable gas detectors for H₂S can also be used for personal protection and are especially useful when working in confined spaces. Easy to use, operated simply by one button and easily attachable to the workers clothing. Portable gas detectors offer a safe monitoring solution alerting the user when preset levels of gas/gases are detected.
For portable Hydrogen Sulphide detection solutions, the Crowcon Gasman and Crowcon Gas-Pro PID both offer an effective solution.
Reducing the risks of Hydrogen Sulphide poisoning in the workplace is a key responsibility and can be managed by following these points:

Via ASCO Numatics FASTSHIP and SAMEDAY Express Delivery Service we are able to deliver 2,000+ ASCO solenoid valves and valve operators from stock direct to you.
By Chris Dodds : estimated reading time 9 minutes
This article has been written to provide information and guidance on the problems and risks associated when using some types of alloys in sour gas environments and the selection and specification of ASCO solenoid valves.
The article focuses on selection of materials for solenoid valves in the Oil & Gas industry where sour gas environments are common due to the very nature of the processes involved in the extraction of natural gas and crude oil.
This article also provides information on the problems sour gas causes to equipment including hydrogen embrittlement and sulphide stress cracking.
We discuss NACE (National Association of Corrosion Engineers) and the standards that have been specifically written for the Oil & Gas industry.
Finally, a case study is included showing how ASCO Numatics have developed NACE compliant solenoid valves for flow control in harsh industrial and offshore environments.
But first things first, what is a solenoid valve?
ASCO solenoid valves are used for the fluid control of air, water, oil or gas normally consisting of an operator and valve body – the operator includes the coil, core, core tube, shading coil and spring. The solenoid valve body is made up of orifices where a disc, piston or diaphragm is positioned. When an electrical current passes through the solenoid valvea magnetic field is created which pulls the core into the open or closed position.
ASCO Solenoid Valves – Largest Range of Valves
Simply, it is natural gas which contains hydrogen sulphide, H2S (the rotten egg smell).
To be precise, if the H2S concentration is >4PPM (parts per million) then natural gas is considered to be sour.
I should say at this point that different countries/agencies have different opinions on the thresholds of what defines sour gas. Hydrogen sulphide is extremely toxic and is also extremely corrosive to pipework and fluid handling equipment when in the presence of water. This type of corrosion is often referred to as Hydrogen Embrittlement.
Sour Gas Causes Stress Corrosion Cracking, Sulphide Stress Corrosion Cracking, Hydrogen-Induced Cracking, Hydrogen Embrittlement, Exfoliation & Sulphide-Oriented Hydrogen-Induced Cracking.
I should say at this point, I am not a chemistry or physics teacher, nor do I confess to being an expert on this topic. There have been lots of papers written about hydrogen embrittlement and there is genuine confusion and disagreement between leading scientists regarding cause, diagnosis and prevention.
However, I will try to provide a basic overview. If there are any experts reading this, feel free to contribute your thoughts on this article. Perhaps, you can give our readers a better explanation and we can feature your contributions on a comment box below.
Hydrogen embrittlement is caused when hydrogen reacts with metals reducing their tensile strength resulting in a weaker structure. It does not affect all metals equally, with the most susceptible being high strength steels, aluminium and titanium alloys. To try and explain the process, hydrogen ions force their way into the grain boundaries of the alloy.
This reaction creates molecular hydrogen which effectively takes up more space between the grain boundaries and weakens the bonds between the grain. This reduces ductility, toughness and tensile strength to a point whereby the alloy cracks.
A major issue with this type of metal failure is that hydrogen embrittlement is difficult to identify. Cracks can be extremely small and only seen under a microscope.
However the end result is likely to be a sudden catastrophic failure. In the onshore and offshore oil and gas industry such failures can lead to major disasters.
Sudden Brittle Fractures In High Strength Steels Resulting From Hydrogen Embrittlement Represent A Dangerous Threat To Industry – not only are there the usual issues of cost such as warranty claims, but in cases of personal injury or property damage, liability points clearly and directly at the manufacturer
An explosion and fire led to the fatal injury of seven employees when a nearly forty-year-old heat exchanger catastrophically failed on April 2, 2010 as a result of high temperature hydrogen attack.
This form of corrosion is slightly different to hydrogen embrittlement but the principals remain the same and the unfortunate accident emphasises why it is so important to minimise the risks of such catastrophic metal failures.
There are many manufacturing processes which can cause hydrogen embrittlement such as cathodic protection, electroplating, phosphating and pickling. In the oil and gas industry, particular concern is reactions between alloys, acids and chemicals which brings us nicely onto the topic of sulphide stress cracking.
Sulphide stress cracking is a form of hydrogen embrittlement. Natural gas and crude oil often contain large amounts of hydrogen sulphide. A reaction between the alloys and hydrogen sulphide create metal sulphides and atomic hydrogen. Atomic hydrogen then either combines to make H2 at the surface of the metal or it diffuses into the metal.
This inevitably results in reduced ductility of the alloy and causes stress cracking.
In the oil and gas industry where sour gas environments are common place, the selection of materials for such environments is critical.
NACE MR0175/ISO 15156NACE MR0175/ISO 15156 is an internationally recognised standard that details requirements and recommendations for selection of alloys.
I’m sure most people reading this will know who NACE are and what they do but for those who don’t:-
NACE was established in 1943 and its mission is to “protect people, assets and the environment from corrosion.” It has over 35,000 members and is recognised globally as the “premier authority for corrosion control solutions.”
NACE MR 0175 / ISO 15156 describes general principles and gives requirements and recommendations for the selection and qualification of metallic materials for service in equipment used in oil and gas production and in natural gas sweetening plants in H2S -containing environments, where the failure of such equipment could pose a risk to the health and safety of the public and personnel or to the environment.
It can be applied to help to avoid costly corrosion damage to the equipment itself – supplementing, but not replacing, the material requirements given in the appropriate design codes, standards or regulations.

ASCO Solenoid Valves Series 327
Solenoid valves are widely used throughout the oil and gas industry.
Applications can include actuator piloting, compressor unloading, redundant control systems and utilities control. Conditions in upstream offshore environments can be extremely harsh as well as being certified as explosive atmospheres.
As already discussed, sour gas is a major problem in such environments meaning there is a requirement for hazardous area solenoid valves that are not only explosion proof but also highly resistant to corrosion.
ASCO Numatics are part of the Emerson group and are a global leader in the design and development of solenoid valves. ASCO were asked to develop a direct acting solenoid valve specifically for sour gas environments.
The design brief was fairly simple:-
The brief may have been simple but ASCO spent a large amount of time, money and resource developing a solenoid valve to meet the above requirements.
T&D, Solenoid Valve Stockists
Firstly, the new solenoid valve is constructed of corrosion-resistant materials to meet NACE MRO175/ISO15156 standards.
All parts that may come into contact with sour gas are NACE compliant but furthermore, so too are the internal components which may be exposed to sour gas during installation and routine maintenance.
The solenoid valve can be supplied as a 3/2 direct operated solenoid in either ¼” or ½”.
Flow rates up to 1.8m3/h are possible and a non breathing design means contaminated air from the environment will not pass through the valve eliminating the potential for corrosion.
The valve is a member of the ASCO 327 solenoid valves range and is based on the principle of a balanced poppet type construction. It can be mounted in any orientation and is available with low powered 
solenoid operators (1.8w). The low power consumption helps to reduce the running costs and increase service life.
ASCO solenoid valves can also be supplied in explosion proof and intrinsically safe options and are also EXIDA & TUV certified (IEC 61508 Functional Safety) so can be used in safety applications up to SIL-3.
ASCO WSCR solenoid valves have been tested for 50ppm sour gas concentration both externally and inside the solenoid housing.
T&D are an Authorised Distributor for ASCO Numatics and work in close partnership with their engineering team to help develop solenoid valves that meet our clients flow control requirements.
Our combined extensive knowledge of the oil and gas industry enables us to design value engineered solutions that meet strict industry guidelines.
ASCO solenoid valves are a quality and reliable solution that provide real benefits to installation engineers and end users throughout the whole lifecycle of the product – they are the most specified valves for critical and safety related applications.
