What are the reasons for a decrease in the inlet pressure of the synthesis tower? If a sudden or gradual drop in the inlet pressure of the synthesis tower is detected during operation, it should be taken seriously and the cause identified. (1) A sudden decrease in the amount of fresh gas will cause a drop in the pressure at the inlet of the synthesis tower. (2) Loss of control over the liquid level in the crude methanol separator caused gas leakage. (3) Leaks caused by damage to the equipment and pipelines of the synthesis system. (4) The pressure gauge is malfunctioning.
1. Due to the effects of previous processes such as gasification, purification, or air separation for gas production, the amount of syngas is low, which affects the pressure entering the tower. 2. The poor working efficiency of the gas compression machinery results in an inability to deliver sufficient volume of gas, leading to low pressure at the inlet of the tower. 3. The effective gas components in the syngas are low; after purification, the gas volume is small and the pressure entering the tower is low. 4. Other reasons from previous processes affect the gas volume, resulting in low pressure at the inlet to the tower. Show all

1. Affected by issues in previous processes, the amount of syngas is low, which impacts the pressure entering the tower. 2. The compressor has poor performance in doing work, resulting in an insufficient volume of gas being delivered and thus low pressure at the tower inlet. 3. The effective gas components in the syngas are low; after purification, the gas volume is small and the pressure entering the tower is low. 4. Leaks caused by damage to the equipment and pipelines of the synthesis system. 5. Pressure gauge failure.
