CENTER FOR INDEPENDENT low-temperature production of liquid carbon dioxide and gaseous nitrogen and liquid oxygen or nitrogen

摘要

The invention relates to equipment and production technology of liquid oxygen or nitrogen, low-temperature carbon dioxide and gaseous nitrogen. The complex can be widely used in various industries, which uses gases such as oxygen, nitrogen and carbon dioxide.; The complex comprises interconnected in a specific pattern process pipelines supplying working media, as well as heat and cold cogeneration plant, a mixer, an absorption-desorption unit, block nitrogen drying, steam boiler, which uses natural gas refrigeration uglekislotno installation absorption lithium bromide and water-ammonia refrigerating machine and air separation plant.; The proposed system provides efficient use of high energy potential of natural gas for the simultaneous production of electrical energy required to drive complex equipment and thermal energy used to obtain the water vapor and production of cold, which are provided by the complex requirements, as well as to liquid low-temperature carbon dioxide gas nitrogen and liquid oxygen or nitrogen.
