摘要:
为满足国际海事组织（IMO）的《国际防止船舶造成污染公约》新规中相关全球低硫重质船用燃料油的质量新要求，某炼油厂2.2 Mt/a 催化裂解（DCC-plus）装置结合自身DCC油浆理化性质中灰分质量分数、含（硅+铝）量超高的特点，于2020年12月进行了DX-CJ 02油浆脱灰剂的首次工业应用。结果表明：该装置DCC油浆经加注DX-CJ 02油浆脱灰剂及产品储罐封罐沉降脱固处理48 h后，除了密度仍略偏高之外，灰分质量分数、含（硅+铝）量均大幅降低，脱除率分别为88.42%，93.33%；这样处理后的DCC油浆可以作为GB 17411—2015中RMG 380#低硫重质船用燃料油的优质调和组分。
Abstract:
In order to meet the new quality requirements for global low-sulfur heavy marine fuel oil stipulated in the new regulations of the International Convention for the Prevention of Pollution from Ships (MARPOL) by the International Maritime Organization(IMO)，a refinery with the 2.2 Mt/a deep catalytic cracking(DCC-plus) unit carried out the first industrial application of DX-CJ 02 oil slurry deashing agent in December 2020，by leveraging the unit′s unique characteristics of ultra-high ash mass fraction and (silicon + aluminum) content in the physicochemical properties of its DCC oil slurry.The results showed that after the DCC oil slurry from the unit was treated with DX-CJ 02 oil slurry deashing agent and subsequently subjected to tank sealing and solid settlement for 48 h，the ash mass fraction and (silicon + aluminum) content were significantly reduced by the removal rate at 88.42% and 93.33%，respectively，except for a slightly high density. The treated DCC oil slurry could serve as a high-quality blending component for RMG 380# low-sulfur heavy marine fuel oil specified in GB 17411—2015，contributing to the optimization of production operation management and quality and efficiency improvement of this unit.
