This project involved two Ariel JGK4 compressor packages driven by Waukesha gas engines that have been configured to allow manual switch from single stage to two stages of compression; for the cases when the suction pressure is dropping below 4.7barA. Scrubbers, pulsation vessels and cooler sections from the second stage are designed at the same diameters and design pressures with the ones from the first stage; in order to provide the most cost-effective solution. All scrubbers are calculated per ASME code. Suction scrubbers have a drain pneumatic pump that will pump condensates to off skid KO drum at 5barg for 30 meters distance in length and 2,5 meters in height.
