【摘要】：聚乙烯作为一种广泛应用的通用树脂类产品,其产量和消费量迅速增长,但生产过程中的高能耗和高污染所造成的环境和社会成本日益显著。将聚乙烯生产成本分为内部成本、外部成本2个单元,建立了1套聚乙烯生产生命周期成本计算模型。实证结果表明,20万t产能聚乙烯生产装置的生产生命周期成本为18.80亿RMB,单位成本为9400RMB/t;内部成本中,原材料采购费用最高,约占总费用的59%;外部成本中,原油开采费用最高,约占总费用的45%;内部关键成本点是原材料采购,外部关键成本点是原油开采、乙烯生产和聚乙烯生产。该模型能够快速有效地计算聚乙烯生产生命周期成本,可用于相关企业节能降耗的计算。
[Abstract]:As a widely used general resin product, the production and consumption of polyethylene are increasing rapidly, but the environmental and social costs caused by high energy consumption and high pollution in the production process are becoming more and more significant.The production cost of polyethylene was divided into two units: internal cost and external cost, and a set of life cycle cost calculation model of polyethylene production was established.The empirical results show that the production life cycle cost of the 200000 t production capacity polyethylene plant is 1.88 billion RMBand the unit cost is 9400 RMB- / t; among the internal costs, the raw material purchase cost is the highest, accounting for about 59% of the total cost; among the external costs, the crude oil extraction cost is the highest.Internal key cost points are raw materials procurement, external key cost points are crude oil extraction, ethylene production and polyethylene production.The model can quickly and effectively calculate the life cycle cost of polyethylene production and can be used to calculate the energy saving and consumption reduction of related enterprises.
