Pipeline Cross-Compression
Also known as pipeline evacuation, re-compression or transfer compression. A compressor takes natural gas from an isolated section of pipeline and injects it into an adjacent section of pipeline. Substantially all of the natural gas is conserved, avoiding venting or flaring.
Pig Trap Blowdowns
Pigs are cylindrical tools that fit inside a pipeline for regular maintenance and internal inspection. Pig traps are the devices where these pigs are put into and removed from a pipeline. The natural gas in these devices are normally vented or flared after each pigging operation. Using cross–compression takes the residual gas in the pig trap and puts it in the main pipeline.
Facility & Vessel Blowdowns
At refineries, gas plants, compressor stations and other industrial facilities, vessels and piping must periodically be emptied of gases and liquids for planned maintenance. Using cross-compression stores these gases and liquids within the facility and avoids burning them off.
Pressure Boosting & Temporary Compression
Our equipment can also be used to boost gas pressures above normal line pressure. This is useful, for example, for pushing pigs from a pig trap into a pipeline or for boosting pressure for temporary gas supply.
Oilwell Blowdowns
Our MultiVAC-35, with its ability to process both liquids and gas through the compressor, is ideal for relieving the gas pressure in both sweet and sour oil wells prior to well servicing. On-site venting or flaring is minimized and the liquids rich gas is kept within the production flowline.
Production Optimization
Our MultiVAC-35 is ideal for evaluating the effects of casing gas compression on productivity of oil wells. Its multiphase abilities allow the compressor to inject liquids rich casing gas into the flowline without any separation ahead of the compressor inlet.
