AGZ specially designed the DiSep^® electric separation system for the Petrochemical Shengli Refinery, which has been running continuously and stably since July 2022, the system is fully automatic and integrated with the plant s DCS system, effectively removing catalyst fine powder and other solid pollutants in the oil slurry to less than 100ppm, of which the silicon-aluminum content (Al+Si) is less than 60ppm, and clarified slurry is supplied to the plant for blending Marine fuel oil RME180. This is the world s first DiSep^® electric separation system that uses oil slurry feed backwashing, the oil slurry feed is converted into clarified oil output for blending ship fuel.

In 2019, AGZ supported a local coke plant in Shandong Province to install a DiSep^® electric separation system with a total capacity of 350,000 tons/year; On the basis of rich experience in oil slurry treatment, combined with the responsiveness, adaptability, selectivity and stability of the DiSep^® electroseparation system, the AGZ engineering team has established an effective and flexible process operation window, which provides a guarantee for the production of high-quality raw materials that meet the needs of downstream needle coke production.

From 2018 to 2019, AGZ signed its first commercial contract with a local refinery in Shandong Province to provide a DiSep^® electrolysis system with an annual oil slurry processing capacity of 560,000 tons. The system drastically reduces the solids content of the slurry from 2000-3000ppm to less than 100ppm.

In 2018, AGZ built the first industrial unit integrated with DiSep^® electrolysis technology and conducted industrial trials to successfully process the oil slurry to meet the strict requirements of the standard for use as a needle coke raw material.
