Relevance of work is caused by the need to decrease energy and resource expenditures. The aggravation of this problem is closely related to constant increase in cost of energy resources: natural gas, electric power, etc. Development of legal, economic and organizational bases of stimulating energy saving and increasing power efficiency is based on the Federal law of the Russian Federation of November 23, 2009 no. 261-FZ "On energy saving and power efficiency increase and on modification of separate acts of the Russian Federation". The aim of the research is to develop a complex of technical actions to increase energy efficiency of oil atmospheric distillation installation "Achinsk Refinery", which allows increasing temperature of raw materials of a column at simultaneous reduction of technological fuel consumption in the furnace and decrease of electric power expenditure in air cooling devices. Research methods: the analysis of technological flows of atmospheric distillation unit. It was ascertained that fuel oil and diesel fraction have a reserve for heat recovery, which is not used for heating feed streams. The authors have selected modern heat-exchange equipment, analyzed its efficiency and made its thermal design. The paper identifies technical and economic indices of the installation reconstruction project. Results: The authors developed a version of three-furnace technological scheme for oil heating with replacement of shell-and-tube heat-exchange equipment by spiral heat exchanger for more complete heat recovery of hot product flows removed from atmospheric column and Stripping column of the oil distillation complex installation. Based on thermal and technical and economic calculations it was proved that the scheme proposed promote reduce of power consumption by air cooling devices decreasing the temperature of incoming technological flows.
