国内首套油浆加热炉投用的技术经济分析

Technical and Economic Analysis of the First Domestic Slurry Heating Furnace

国内首次采用“油浆单独加热、炉后混炼”的工艺技术对催化油浆进行加工处理,利用对含有油浆加热炉在内的延迟焦化装置进行工艺标定得到的数据,通过测算得到催化油浆经过油浆加热炉得到产品馏分分布,并对油浆进加热炉的生产工艺进行经济核算,同时与油浆调和低硫RMG380残渣性船用燃料油进行经济对比,得到当前价格体系下的油浆加工效益相对较好的工艺路径。

For the first time in China,the technology of“single slurry heating and mixing after furnace”is used to process the catalytic slurry.Using the process calibration data of the delayed coking unit including the slurry heating furnace,the catalytic oil is measured and calculated.The slurry passes through the slurry heating furnace to obtain the product fraction distribution,and the production process of the slurry into the heating furnace is economically calculated.At the same time,an economic contrast analysis with low-sulfur RMG380 residue marine fuel oil was carried out to obtain a relatively good process path for oil slurry processing under the current price system.
