[Abstract]:This paper discusses the importance of low temperature waste heat recovery in green and low carbon society, and the application status of low temperature waste heat recovery technology. The aromatics combination unit is a typical high energy consumption unit in refinery and chemical enterprises. Before the 600000 ton / year aromatics unit was put into production in Hainan, all aromatics units in the world were monopolized by UOPand French IFP technology. A large amount of low temperature heat at the top of the tower and residual heat of the reaction material are used in these devices, which not only waste the low temperature heat at the top of the tower, but also consume a lot of electric energy at the same time. Sinopec Hainan Refining and Chemical Co., Ltd (abbreviated as Hainan Refining and Chemical Co., Ltd.) uses the process package technology of Sinopec's independent intellectual property rights to make a great breakthrough in energy saving and consumption reduction. On the one hand, for the tower with slightly higher top temperature in the traditional process, the steam can be produced by properly increasing the top pressure and temperature, and the steam emitted by the tower can be superheated through the convection section of the heating furnace to promote the steam turbine to generate electricity. On the other hand, for the tower with relatively low temperature at the top of the tower, a hot water exchanger is installed on the top of the tower, and the hot water is transferred to the Karina circulating hot water generation system and the ORC hot water power generation system to generate electricity after heat transfer to 120 鈩
