Residue Hydrotreating: A Chinese-Made Circulating Oil Pump Runs Through the First Turnaround at Zhenhai
A domestically designed and built circulating oil pump has run smoothly through the first turnaround and restart of Sinopec Zhenhai's 5.6 million t/y combined-bed residue hydrotreating unit, replacing imported equipment.
Lead
A circulating oil pump designed and manufactured by Huasheng Pump & Valve Co. (华升泵阀) has operated smoothly through the first scheduled overhaul and successful first-attempt restart of the 5.6 million-tonne-per-year combined-bed residue hydrotreating unit at Sinopec Zhenhai Refining & Chemical, according to a trade-press industry roundup.
Facts
The duty. The pump, designated 0217-P-2200, is a core rotating machine on the unit's circulation loop. The unit applies the combined "ebullated–fixed" bed residue hydrotreating route and is one of the key technology programmes under Sinopec's long-running research initiative. (Source: a trade-press industry roundup, October 2026.)
The record stated. The unit completed its first overhaul and restarted successfully on the first attempt; the pump ran steadily through the restart. The coverage describes the machine as domestic equipment replacing an imported one. (Source: the same.)
The maker. Huasheng Pump & Valve describes the pump as its own design and manufacture. (Source: the same.)
