利用超重力辅助强化技术和自主研发的TH-CJ型油浆沉降剂,在中海油惠州石化1.2 Mt/a 催化裂化装置中进行了催化裂化外甩油浆脱固侧线试验。结果表明:在实验室,采用传统沉降法需要48 h甚至更长时间才能将油浆灰分质量分数降至0.1%以下,如此可满足GB 17411—2015要求,而采用超重力分离技术侧线试验仅需要3 min;前者液体收率(质量分数)为85%~90%,而后者在97%以上;超重力分离侧线试验在连续稳定运行144个周期期间,油浆的脱灰率保持在86.21%之上,处理后油浆灰分质量分数始终低于0.1%,比传统沉降法更具技术优势。

By adopting the developed super-gravity assisted enhancing technology and the self-innovated TH-CJ type slurry settling agents, the sideline test of fluid catalytic cracking(FCC) external slurry solid removal was carried out in the 1.2 Mt/a FCC unit of Huizhou Petrochemical Co Ltd. The results showed that the traditional settling method in the laboratory required 48 h or even longer time to reduce ash content in slurry to less than 0.1% to meet the requirements specified in GB 17411—2015, while the sideline test that adopting super-gravity separation technology only required 3 min to meet the same specification mentioned above.The liquid yield of the former was 85%-90%, while that of the latter was above 97%. During 144 cycles of continuous operation in the supper-gravity separation sideline test, the solid removal rate had remained above 86.21%, and the mass fraction of slurry solid after treatment had been less than 0.1%. So this super-gravity separation technology had more technical advantages than the traditional settling method.
