RECENT EXPERIENCES IN FULL LOAD FULL PRESSURE SHOP TESTING OF A HIGH PRESSURE GAS INJECTION CENTRIFUGAL COMPRESSOR

摘要

The second phase of the Prudhoe Bay Gas Handling Expansion Project (GHX-2) included several large, gas turbine driven, tandem compressors. Increasing gas offtake and the resulting increase in high pressure, gas reinjection requirements created the need for a near 50 percent increase in gas reinjection capacity and addition of nearly a quarter of a million hp. Each of the four gas turbine/tandem compressor trains is housed in a separate, enclosed module weighing up to 5400 tons. These modularized oil and gas processing facilities have been designed and fabricated in the lower 48 states. Once completed, the modules have been sealifted to the North Slope of Alaska, offloaded from the transport barges, and then moved into place with large, specially designed transport vehicles.
