Abstract: Reasonable utilization of low temperature heat is one of the important potentials of energy saving and consumption reduction in refining and chemical enterprises industry, butit is difficult to make full use of low temperature heat due to its random and scattered utilization. In view of the practical problems of low temperature heat recovery system in the enterprise, such as decentralized construction, decentralized management and low operating economy, etc.,the key problems of the optimization of low temperature heat recovery system in refining and chemical enterprises were deeply analyzed, the optimization technology of low temperature heat recovery system in petrochemical enterprises was put forward, the whole process optimization model of low temperature heat recovery system was established, and the operation optimization and transformation optimization of low temperature heat recovery systemwere carried out. The case analysis results showed that the technology could effectively reduce the operation cost of the low temperature heat recovery system, bring good economic benefits and energy saving effect to the enterprise.

Key words: low temperature heat, optimization technology, energy saving
