PINCH ANALYSIS SCHEME OF PRIMARY OIL PROCESSING

摘要

Using pinch analysis considered the scheme elou-at-3 with a capacity of 3 million tons/year. During the work of the new scheme was proposed strapping heat exchangers, which when compared with the existing is better. When moving to the proposed scheme of heat increased raw materials supply temperature in oven with 240 to 250 °C, allowing decreased fuel consumption in a furnace at 309 kg/h, and therefore reduced the cost of heating fuel.The most significant role of heat exchange units AT and plays AVT, blocks heat transfer which due to the large amount of heat is the most complex systems.Pinch analysis is one of the best methods for analysis of heat transfer systems in the chemical and petrochemical industry, and is based on thermal analysis system process flows.For refining and petrochemical enterprises, most of which launched in 60-70 last century, the use of pinch technology allows achieving reduction of energy consumption and, consequently, financial payments behind them, 30-50%, and in some cases on separate installations to 70%.The program that implements the calculation by the method of Pinch analysis allows you to make data-based computation to build composite curves of hot and cold streams.Buildings show the possibility of increasing the maximum heat recovery. This enables you to optimize the heat flows in the hardware and choose the most efficient schemes of heat exchange.
