Analysis: Unstable operation during hydrolysis
Thread Content
The hydrolysis system in our plant is currently operating in an unstable manner; it is difficult to operate the hydrolysis tower. Under abnormal conditions, the hydrolysis pressure is 1.8 MPa and the temperature of the liquid output is 195°C. The level of the hydrolysis liquid is at its maximum and cannot be adjusted, while the temperature of the tower wall is 175°C and that of the gas phase is 170°C. What confuses us is why the liquid cannot be drained I hope to get help from fellow sea lovers.
What is your hydrolysis pressure under normal conditions? Is your gas outlet unobstructed? It’s possible that the pneumatic valve is showing incorrect readings.
