超重力辅助强化油浆脱固技术

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。

Enhanced oil slurry solid removal technology under super-gravity assistance

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.
