在中国,石化企业既是能源生产大户,也是能源消耗大户。由于其为典型的连续过程大生产模式,原料在产品成本中占有很大的比重,车间自动化程度相对较高,对反应装置、仪表、设备状况要求很高,在不进行项目技术改造的前提下,生产过程中节约能耗难 In China, petrochemical enterprises are not only major energy producers but also large consumers of energy. Because it is a typical large-scale production mode of continuous process, raw materials occupy a large proportion of product cost, and the degree of workshop automation is relatively high. The requirements on the reaction device, instrument and equipment are very high. Without technical renovation of the project , Saving energy during production difficult
