摘要
综述了近年来国内炼油企业为降低企业能耗、提高经济效益而普遍开展的低温热综合利用现状,着重介绍了常减压装置、催化裂化装置、焦化装置、加氢装置及蒸汽凝结水等主要低温热源的回收利用情况。从现有情况看,国内炼油企业节能降耗成果显著,并取得了良好的经济效益和社会效益。
Utilization of low-temperature heat has been carried out in the domestic refineries to reduce energy consumption and improve economic efficiency. In this paper, utilization status of low-temperature heat in domestic refineries was reviewed. Recovery and utilization situation of low-temperature heat from atmospheric and vacuum distillation units, catalytic cracking units, coking plants, hydrogenation plants and so on was discussed. From the existing situation, the domestic refineries have done well in energy saving, and have achieved good economic and social benefits.
