海上平台烟气余热利用分析与工艺优化

Analysis and Optimization of Flue Gas Waste Heat Utilization on Offshore Platform

依托南海某在建钻采平台,从工艺原理、工艺流程、有机工质的选择、安全性、能源节约及降低二氧化碳排放等方面进行分析,论证有机朗肯循环(Organic Rankine Cycle,ORC)技术在海上平台应用的可行性。根据能量梯级利用原则,设计一套优化的烟气-导热油-热用户系统,利用透平废热实现ORC发电、生产系统加热及溴化锂制冷的热电冷联产系统。

Basing on a drilling platform under construction in the South China Sea,the feasibility of applying Rganic Rankine Cycle(ORC)technology in the offshore platform was discussed from the process principle,process flow,organic working medium selection,safety,energy saving and reduction of carbon dioxide emission.According to the principle of energy cascade utilization,a set of optimized flue gas-heat transfer oil-heat user system was designed to establish a turbine waste heat-based cogeneration system which boasting of ORC power generation,production system heating and lithium bromide refrigeration.
