高硫、高酸重劣质原油的优化采购及加工

针对国际原油市场高硫、高酸重质原油成本低廉的优势，应用中国石化长岭分公司PIMS模型和原油混炼技术，通过做好劣质原油配套加工油种选择优化，以及加工流程、化工轻油流向、运输计划等优化，成功实现对适量高硫、高酸重质原油的采购和安全平稳加工，产品出厂质量合格，炼油企业原油采购成本显著降低。

OPTIMIZATION OF PROCUREMENT AND PROCESSING LOW QUALITY SOUR AND ACIDIC HEAVY CRUDES

As the cost of high sulfur and highly acidic heavy crude oils are much lower than the light crude oils in the open oil market, SINOPEC Changling Company purchased some low quality sour and acidic heavy crudes for cost reduction and successfully processed these crudes with crude oil mixing technology and based on Changling’s own PIMS model. By optimizing processing scheme, naphtha flow, crude oil transportation plan and the proper selection of mix-processing crudes, the low quality crude oils were processed smoothly and the qualities of products well met the requirements. The cost of crude oil reduced significantly, thus great economic benefit was obtained.
