Modelirovanie i analiz energosberegayushchey sistemy na baze absorbtsionnoy bromistolitievoy kholodil'noy mashiny dlya ustanovok razdeleniya vozdukha

To produce liquid and gaseous industrial gases the air separation plants (ASP) are used. High energy cost that defines a primecost of produce is typical for the ASP. Due to this fact the problem of energy supply at operation of such plants is topical as well as of great practical importance. The implementation of energy saving technologies allows reducing the cost and improving the quality of products produced. The air separation plant KzhKzh0,04 (Astrakhan) was the object to investigate. The Astrakhan oxygen station of “Kislorod”, closed corporation, is equipped with two KzhKzh0,04 ASP to supply in part the enterprises of the Astrakhan region with liquid oxygen. The results of the industrial experiment carried out on the equipment operating in 2010-2013 were analyzed. As a result an energy saving system based on an absorption lithium bromide refrigerating machine (ABRM) was offered. The analysis of efficiency of the energy saving system was carried out on the basis of modeling with elaboration of the program “Analysis of power efficiency of an air separation plant using ABRM”. The efficiency of the energy saving system operation may be defined at wide range of external parameters change.
