对巴士拉原油、龙卡多原油、梵高原油、邦加原油的一般性质、直馏产品收率、产品性质进行比较和数据分析,结合大连石化现状,对原油加工方案进行探讨。结论认为,巴士拉原油各直馏馏分的收率比例适中,硫含量高,需要与其他硫含量低的原油混炼;龙卡多原油各直馏馏分的收率比例适中,但是硫含量高,酸值达到0.5mgKOH/g,需要与其他硫含量低、酸值低的原油混炼;邦加原油除减压塔底油收率稍低外,其他各直馏馏分的收率比例适中,但酸值高达0.5mgKOH/g,需要与其他酸值含量低的原油混炼;梵高原油为偏重原油,重整原料、航煤和柴油馏分收率小,大部分为减压馏分和渣油馏分,酸值超过1.0mgKOH/g,加工时会严重腐蚀常减压装置,应根据需要掺炼其他酸值低的原油,后续加工可通过催化裂化或加氢裂化等深度加工工艺,生产出高价值的轻馏分油。原油评价为生产计划系统、生产调度排产系统和原油优化调合系统提供数据支持,并为选择效益最优的原油采购方案,确保生产装置平稳运行,保证原油加工效益最大化提供技术支持。
The paper compares and analyzes the properties of Basra crude oil, Longkatuo crude oil, Van Gogh crude oil and Bunge crude oil, the yield of straight-run product and the nature of the product. Combining with the current situation of Dalian Petrochemical, the crude oil processing plan is discussed. The conclusion is that Basalt crude oil has a moderate proportion of straight-run distillates and a high sulfur content, which needs to be mixed with other crude oil with low sulfur content. The yield of each straight-run distillate of Longkatuo crude oil is moderate but the sulfur content is high and the acid value 0.5mgKOH / g, need to be mixed with other crude oil with low sulfur content and low acid value. The yield of Bonded crude oil except for the bottom oil of vacuum distillation tower is slightly lower, but the yield of other straight-run distillates is moderate, but the acid value Up to 0.5mgKOH / g, need to be mixed with other crude oil with low acid value; Van Gogh crude oil is heavy crude oil, reformed raw materials, aviation coal and diesel fractions yield small, mostly vacuum distillation and residue fractions, acid The value of more than 1.0mgKOH / g, the processing will be seriously corrosive atmospheric and vacuum unit, should be blended with other low acid value as required crude oil, follow-up processing through catalytic cracking or hydrocracking and other advanced processing technology to produce high-value light Distillate oil. The crude oil evaluation provides data support for the production planning system, production scheduling system and crude oil blending system. It also provides technical support for selecting the most effective crude oil procurement plan, ensuring the smooth operation of the production plant and maximizing the profitability of crude oil processing.
