Abstract
This paper analyzes the problems of the energy consumption and energy saving potentials of residue hydrogenation unit in SINOPEC Tianjin Company.The energy consumption of the residue hydrogenation unit can be reduced by 3.69 kgEO/t,which effectively lower costs and increase profits for the company,through a series of optimization measures,such as the addition of Robust-IPC full-process intelligent control system,the energy-saving transformation of lean amine pump hydraulic turbine and lean amine booster pump,the transformation of waste heat recovery system of heating furnace,the increase of online monitoring facilities for CO content in heating furnace,the optimization of hydrogen-oil ratio and quenching hydrogen process,and the recovery of low-temperature heat at the top of fractionation tower,etc.
