摘要
Abstract
To enhance the economic effectiveness of the crude benzene recovered from oil shale raw coke oven gas, this paper study the separation sequences for the crude benzene, simulate the process of conventional sequences and thermally coupled distillation sequences and calculate energy consumption and thermally efficiency of these separation sequences. The result shows that thermally coupled distillation sequences is the most effective energy-saving separation sequence to separate the crude benzene mixture in which light component is the major fraction. Compared with the direct sequence of conventional distillation, the result of energy consumption analysis indicates that thermally coupled distillation sequence could save energy up to 35% and its thermodynamic efficiency is enhanced from 7. 4% to 11. 6%.关键词
