Skid-mounted low temperature BOG compressor unit

The compressor adopts a medium-speed rotating structure type, which has obvious characteristics of high mechanical efficiency and low energy consumption compared with the labyrinth compressor;

Compared with the low-speed compressor, it has the characteristics of small size, less leakage, small friction coefficient and low energy consumption; the inlet temperature of the compressor can be as low as -162 ℃, and BOG does not need to be reheated:

Horizontal symmetrical balanced reciprocating piston compressor unit, the rotating inertia force and moment are completely balanced, the reciprocating mass difference of the moving column is strictly controlled, and the vibration is small;

The cylinder is lubricated without oil, and the average piston speed is less than or equal to 3.6 m/s; The structural design of the optical axis of the compressor crankshaft and the motor shaft adopts the industry's first-class coupling direct connection. The cylinder is naturally cooled, the design without water sleeve, and the public works requirements are lower;

Overall skid installation, complete piping, cold preservation and nitrogen pre-cooling in the factory; On-site installation workload is small and construction period is short.
