The original air compressor station of a stainless steel enterprise has a total of 60m ³/ Min screw air compressor 7 sets. The project adopts energy-saving sharing (EMC) mode of cooperation, and the contract period is six years. In April 2019, excellent gas storage energy signed an EMC contract with the enterprise. As one of the largest stainless steel manufacturers in China, due to industrial application factors, compressed air energy consumption accounts for a large production cost. Through the implementation of energy trusteeship project, the comprehensive cost of compressed air is reduced by 26% on the basis of the same gas consumption; Good economic and social benefits have been achieved.
