Embodiment Construction
[0015] The present invention will be further described in detail below through specific embodiments.
[0016] Such as figure 1 As shown, a pre-refrigerant compression skid-mounted module for liquefied natural gas includes a skid-mounted frame, a pre-refrigerant compressor 7, a compressor lubrication system 8, and a lubricating oil cooling heat exchanger integrated on the skid-mounted frame 6. Pre-refrigerant filter, compressor lubricating oil fine separator 5 and pre-refrigerant storage tank 4.
[0017] The skid-mounted frame is in the shape of a rectangular parallelepiped. The skid-mounted frame includes a bottom frame 2, a top frame 1, and eight intermediate connecting rods 3 connecting the top frame 1 and the bottom frame 2, the bottom frame 2, the top frame 1 and the connecting rods. 3 are welded and fixed to each other. The eight middle connecting rods 3 are evenly distributed on both sides of the bottom frame 2 and the top frame 1. The middle connecting rods 3 divide the ski...
