Abstract

Abstract: According to the characteristics of the captive power plant of the petrochemical enterprise, the load optimal distribution model based on heat balance (Model One) and the one based on fuel and electricity prices (Model Two) are established and implemented online simultaneously on the basis of the production process monitoring and the optimization system of the plant. Through the analysis of the operation data before and after the optimization, it is shown that the coal consumption can be saved at least 4.5 g/(kW·h) with Model One, and the profit can be increased by 6 492.16 yuan/h with Model Two. The two models can be generally applied to the captive power plants the petrochemical enterprises.

Key words: petrochemical enterprises, captive power plant, heat balance, fuel price, electricity price, load optimal distribution
