The application areas of gas pipeline pneumatic testing are considered. A set of process operations during pneumatic testing is investigated. Experience with mobile compressor units is reviewed, and a concept for a unit similar to the LMF 67/150 — D is developed. This unit consists of a piston and screw compressor operating from a single drive and is also equipped with air drying and nitrogen generation units. The key requirements for dried air and nitrogen are determined, which were used to select a pressure swing adsorption unit, as well as gas separators for a membrane nitrogen generator. The unit's throughput for dried air and nitrogen is determined. A flow chart for the unit's operation when connected to the tested gas pipeline is developed.
