Abstract: In order to make full use of the pressure energy, the domestic condensate treatment system mostly adopts the multi-stage depressurization flash + stripping stabilization process. The condensate stabilization will consume a large amount of heat source, the form of condensate treatment system heat exchange are relatively simple, and the heat exchange network is not optimized enough, resulting in more waste of waste heat resources. In order to save the energy and consumption, and achieve the goal of economic green production, it is necessary to optimize the energy consumption of the condensate treatment system and propose a transformation plan. Taking the YM condensate treatment system as an example, through the optimization study of the energy utilization scheme of the condensate treatment system, after the sequential heat exchange and the wide-channel heat exchanger optimization, the heat transfer efficiency of the condensate treatment system was greatly improved. The annual fuel gas cost could be reduced by 954 000 yuan, and the reformation investment could be recouped in one year. The economic benefit of the treatment plant was improved, and the comprehensive energy consumption of unit product was reduced.
