POPR 012 - Gas Process Operations Level B

Gas Process Operations (GPO) was developed to provide the Gas Plant Operator with a basic understanding of the theory associated with plant operations.
The Gas Process Operations Level B component reviews Plant Equipment. Students will be introduced to pumps, valves, pipes, fittings, engines, gaskets, heat exchangers, and gas turbines. Students will study gas compression in depth and become familiar with classification and types, compressors and their components, rotary machines, basic and operational controls, auxiliaries, and lubrication.
