Level Measurement In Crude Oil Processing For Storing Raw & Finished Products

Published 29 Jun 2017

Crude Oil Level Measurement

In the petrochemical industry in order for the crude oil process to run continuously and smoothly care has to be taken when storing raw and finished products. Delivery of the crude oil is via pipeline or ship and stored in a large tank until it is ready for final processing.

Accurate level measurement of products of distillation is essential whilst they are being stored in different sized tanks.

In the past it was expensive as calibratable measuring devices were implemented for level measurement. Nowadays cheaper and low maintenance measuring systems are used for small and medium sized tanks. Products are now usually measured by calibratable flow meters while being moved.

Simple Contactless Measurement With VEGAPULS 62

The radar sensor VEGAPULS 62 is suitable for level measurement especially in small and mid-size refinery vessels. Being small and light, the level sensor can be mounted without difficulty in an existing mounting boss, or integrated into a manhole.

With an accuracy of 3 mm, the VEGAPULS 62 sensor is ideal for inventory tank management and can easily be coupled with superordinate systems. Through the use of a temperature adapter, process temperatures up to 200 °C can be realised enabling level measurement of highly viscous distillation products such as lubricating oil or bitumen. VEGAPULS 62 has also proven itself very well as overfill protection in floating roof vessels.

VEGAFLEX 61 – Using Existing Standpipes & New Technology

Until now, mechanical measuring systems such as float gauges or displacers were often implemented. To guarantee precise measuring results, such devices (VEGAFLEX 61) are used mainly in standpipes. Due to the large equalisation holes in the pipes, it is often impossible to replace existing systems with free radiating radar sensors – the holes cause interfering reflections.

This is a situation in which the guided microwave device provides a simple, as well as reliable, solution for level measurement. When the sensor is mounted in the center of the existing standpipe, a coaxial measuring system with optimal signal transmission is created. The result is high accuracy and dependability, without large expenditures for installation and setup.

Reliable Overfill Protection – VEGASWING 63

In principle, a continuous measuring system can be implemented for overfill protection. However, as a completely different measuring principle, the vibrating level switch VEGASWING 63 provides additional safety. Independent of product characteristics, the level sensor reliably detects the threshold level and thus ensures a high degree of plant safety.

The annual instrument check is carried out quickly and reliably with a simple push of a button on the instrument. VEGASWING 63 is ideally suited for leakage monitoring in tank enclosures.
