低低压蒸汽波动对蒲城聚丙烯工艺的影响及对策

Effects of Low-low Pressure Steam Fluctuations about Pucheng Polypropylene Project and Countermeasures

分析蒸汽波动对试车过程中聚丙烯工艺影响。维持蒸汽压力520k Pa;修订反应器进出料系统、高压闪蒸系统、气蒸器相关PID参数;控制高压袋滤器的温度约84℃、高压丙烯洗涤塔液位约50%及汽蒸器温度约105℃,使聚丙烯系统反应器平稳运行。

Analysised effects of low - low pressure steam fluctuations about Pucheng polyprepylene project. Maintain the steam pressure of 0.5 MPa; Revised front - rear reactor system, high - pressure flash system, gas steamer relevant PID parameters; Control the temperature of the high pressure bag filter is about 84 ℃, the high pressure scrubber propylene liquid level about 50% and the steamer for temperature about 105 ℃, the polypropylene reactor system running steadily.
