mechanical engineering; compressor plants. SUBSTANCE: proposed invention can be used in compressor stations for filling cylinders with compressed natural gas. Plant has compressor and gas primary preparation unit. Drying and regeneration unit has two adsorbers connected in parallel in parallel to delivery line, gas drying line and adsorbent regeneration line. Adsorbers are connected to delivery line through adsorbent regeneration line and are interconnected in tandem in direction of gas flow by means of additional line. Gas filter, cooler and moisture-and-oil separator are installed in tandem in direction of gas flow on additional line. Moisture-and-oil separator is installed on compressor delivery line. Gas heater is made in form of recuperator installed on intermediate stage at delivery side. Recuperator is connected with delivery line of compressor last but one stage and last stage suction line by means of additional pipelines. EFFECT: provision of constant output. 2 cl |
