Low-temperature methanol washing
Thread Content
Which of those devices used for low-temperature methanol washing during initial operation require washing with water? Is the water washing scheduled after purging? Does the tower also need to be washed with water?
First, there is a hydraulic test of the pipes, followed by purging. After the purging is successful, consideration is given to installing trays; then an airtightness test is conducted (not entirely accurate). After that, there is a water operation test, chemical addition, and pressure retention in the pipes for membrane formation!
After the purging is complete, it is advisable, if possible, to wash all the equipment with pressurized water in order to clean out any areas that are difficult to reach inside the equipment as well as any debris at the bottom of the equipment Then a airtightness test is conducted, followed by a water test of the large system (the solution circulation system), in order to reduce the frequency of cleaning the inlet filters of various pumps and the filters themselves!
Water circulation is primarily used as a substitute for methanol in the circulation process for two purposes: 1. To use water instead of methanol in order to simulate normal operating conditions and check the performance of various instruments; 2. To remove impurities from the equipment by using water as the medium for cleaning. Water circulation must be carried out after the purging process is complete, as large pieces of impurities could otherwise end up on the trays, making it difficult to clean them. Tower equipment certainly needs to be washed with water, as the main purpose of this washing is to clean the tower. After the washing is complete, the system can be dried with nitrogen, after which a methanol circulation can be established
Under what conditions is it not necessary to wash the car while driving? Everyone, keep the discussion going!
There is no need to wash the vehicle with water after parking it for maintenance and then starting it up again; however, if it is the first time driving the vehicle, it’s advisable to wash it with water if conditions permit!
The original vehicle must be washed with water. It mainly removes dirt from the system. There is also the hydrostatic test. In fact, it is to prevent too much dirt from being carried in with the methanol. . Be careful when washing. The densities are different. Prevent the pump from being overloaded
Which of those devices used for low-temperature methanol washing during initial operation require washing with water? Is the water washing scheduled after purging? Does the tower also need to be washed with water? The procedure to be followed for low-temperature methanol washing during initial operation is as follows: 1. Manually clean all tanks, towers, and vessels ； 2. Blowing out or water flushing (blowing out for pressure-bearing equipment, water flushing for non-pressure-bearing equipment) ； 3. Airtightness test (not required for pressure-free equipment) ； 4. High tower settlement test ； 5. Water flushing, water-driven commissioning ； 6. Nitrogen drying and purging ； 7. The system introduces methanol ； 8. Wait to drive
