Internal leakage in the tubes of the methanol synthesis tower
Thread Content
If leakage occurs between the tubes of a shell-and-tube methanol synthesis tower and its tube sheet welds during operation, what abnormal phenomena will occur in the process?
During operation, when the system pressure exceeds the steam pressure, gases mix into the steam, causing the boiler pressure to rise, the quality of the steam to decline, the pH level to drop, and the wastewater to have a methanol odor; this can be detected through analyses of the steam and boiler water quality. When parking, the steam pressure is higher than the water pressure; water enters the bed and submerges the catalyst: L
The second floor’s explanation is quite comprehensive. Additional abnormal phenomena include a decrease in the output of crude methanol, a sharp rise in the pressure of the synthesis drum, and excessive fluctuations in the liquid level of the drum
