Planning optimization of PVC production by calcium carbide method based on discrete time representation
摘要
Abstract
At present,polyvinyl chloride(PVC)by calcium carbide method had few studies in planning optimization. In order to solve this problem,a mixed integer nonlinear programming(MINLP) planning optimization model was established. A plant-wide process of PVC by calcium carbide method including raw material supply,calcium carbide production,salt water electrolysis,vinyl chloride (VCM) polymerization and the delivery of PVC was investigated in this paper. Considering the raw material cost,inventory cost,delay cost and electricity consumption cost,the working state and production rate of equipment,electricity supply and material supply were determined optimally based on the discrete time representation in order to minimize the total cost. According to the actual industry data,nonlinear electricity consumption characteristics of calcium carbide furnaces and electrolytic bathes were studied to reduce energy loss and improve the economic profits. A case study was provided to verify the effectiveness of the proposed model. The results showed that the proposed model is superior to the separate model in energy saving and total cost by 9.0% and 8.1% respectively.关键词
