一、前言我国近几年原油产量一直稳定在1亿吨左右,但却有1/3左右的原油和重油被当做燃料烧掉。由于烧油量增加,炼厂原油加工深度无法提高。目前炼油厂加工能力大于实际加工量,压缩烧油,增加原油加工量,减少炼厂重油生产量对于提高炼厂加工深度和增加轻质油品产量、提高炼油经济效益都极为重要。附图是商品燃料油与六大类产品(汽、煤、柴、石脑油、化工轻油和润滑油)数量关系图,从图可见,它们之间呈线性关系。在原油加工量相同、其它油品数量不变的情况下,商品燃料油减少生产(比原来)100万吨,六大类产品大致可增加83-86
I. Introduction China’s crude oil output in recent years has been stable at 100 million tons, but about one-third of crude oil and heavy oil are burned as fuel. Refinery crude oil processing depth can not be increased due to the increase in oil consumption. At present, the processing capacity of refineries is larger than the actual processing volume. Compression of oil burning, increasing the crude oil processing volume and reducing the refinery heavy oil production volume are very important for improving the refinery processing depth, increasing the output of light oil products, and improving the economic benefits of oil refining. The figure is the relationship between the quantity of commercial fuel oil and the six categories of products (steam, coal, diesel, naphtha, chemical light oil and lubricating oil). As can be seen from the figure, there is a linear relationship between them. In the same amount of crude oil processed, the other the same amount of oil, the reduction of production of commercial fuel oil production (compared with the original) 1 million tons, six major categories of products can be increased by about 83-86
