He article presents a study of gas fractionating plant, which is associated with the problem of high energy consumption for heating and cooling of technological flows. To solve this problem, a method of heat utilization of isopentane fraction streams and gas gasoline for heating cold streams was proposed. This process of heat exchange was integrated into the existing network of heat exchangers and analyzed using the pinch analysis method. The plant model developed at Aspen HYSYS using data from real plants was exported to Aspen Energy Analyzer. Analysis of the heat exchange network showed that the consumption of hot and cold energy can be reduced by 6.4% and 4.4%, respectively.
