Pressure Measurement & Control


Multisensing technology in gas lift applications

March 2012 Pressure Measurement & Control

Cost saving with EJX pressure transmitters.

In a typical gas lift system, a compressed gas is injected into the production tubing to reduce the hydrostatic pressure of the fluid column. As a result, oil or gas can be produced at higher flow rates. In this application, the flow volume of injection gas pressure and produced oil/gas are measured differentially using in-line gauge pressure transmitters; compliance with the latest safety standards such as IEC 61508 is becoming increasingly important on these types of production line.

Particularly challenging is unexpected overpressure from underground being generated in the line. The process static pressure of the injection gas line is very high (approximately 1,7 MPa), so In order to secure accurate and reliable measurement the stability of the transmitter in the process is critically important.

The solution

Yokogawa’s EJX110A multisensing transmitter delivers the two process variables of differential pressure and static pressure simultaneously. This enables end users to save the cost of a gauge pressure transmitter for monitoring the line pressure.

The DPharp silicone resonant digital sensor exhibits superior stability and repeatability even under overpressure or high static pressure condition. In addition, EJX series guarantees long-term stability, 0,1% of URL for 120 months, under real-world process conditions.

With its unique fail-safe feature of DPharp sensor, EJX series transmitters, except fieldbus communication types, are certified by RWTUV in compliance with IEC 61508 as standard. The EJX delivers reliability for plant safety while optimising operational uptime.
