In this operating cycle, the V-sulphur plant has treated more than 291,000 tons of acid gas, recovered 245,000 tons of sulfur, and supplied nearly 500,000 tons of steam at 3.5 MPa. The average energy consumption of the plant was -10 kg of standard oil/ton, resulting in economic benefits2. Billion; The average concentration of sulfur dioxide emissions in flue gas volume is 516 mg/m3, far lower than the national emission standard of 1200 mg/m3, and environmental protection benefits are obvious.
In more than four years, Zhenhai Refining & Chemical Refinery Co., Ltd. has made great efforts in smooth production. In response to the problem of large fluctuations in acid gas flow and concentration, the company has given full play to the advantages of high degree of automatic control of the equipment and strived to grasp the level of automation and control. The device instrumentation control rate reaches 100%, and the complex loop control rate reaches over 90%, which greatly improves the device's anti-jamming capability. Concerning the problem of corrosion leakage of waste heat boilers, they not only added new facilities, but also continuously modified the boiler's continuous sewerage system so that the qualified rate of boiler water indicators reached 99.99%, improving the operating conditions of the boilers. . In addition, they further improved the operating process, eliminated the long-standing phenomenon of "steam resonance" in the steam superheater, and removed obstacles for the long-term operation of the plant.
Zhenhai V sulfur plant long-term operation to create the most similar domestic
