Generally these stations are used for the treatment of gas coming from a main pipeline of gas net, in order to supply the required flow rate of gas to the end user at the required process conditions (pressure, temperature, flowrate and cleaning conditions).

These typical stations consist of a separating / filtering stage, a heating stage (if required), a reduction stage, a metering stage, a final filtering stage (if required), drain collection tank and cold stack (if required).

Forain can take care of the complete engineering (process, civil, mechanical, electrical, control and automation) according to Customer requirement.

For each stage mentioned above, Forain makes a study in order to offer the most suitable type of equipment which also complies with applicable specifications and international standard codes.

Separating & filtering stage can be sized by choosing the most suitable type of vessel of Forain products. Heating stage (if required by the process condition) can be done by lndirect Water Bath Heater, or electrical heater, or boiler and heat exchanger.

Manufacturing of equipment and piping can be done in the workshop, fully tested and assembled on skid (if requested) and then delivered to site for erection and complete installation.

lnterconnecting piping can be also manufactured at site (if necessary).

After installation completion, Forain can manage the commissioning and start up activities.

Accessory Instrumentation

As concerns accessory instrumentation, PRMS plant  is  supplied complete with all valves, instrumentation and control panel for the safe and reliable performance of the station.

Market presence
