Hello everyone: Why is filter S2 designed in this location within the low-temperature methanol washing process? Is it because of the high sulfur content here? What mesh size is generally good for this application? How long is the cleaning cycle usually? Which cleaning method is better? Is backwashing feasible? If possible, who can provide relevant information? Could I also get the manufacturer’s contact details? The filter elements used in our factory are made of sintered metal, and they are difficult to clean. Is there any better filtering method available? If so, I hope you can provide information on the relevant filters.

The filter installed at the bottom of the tower is intended to remove impurities such as iron carbide that are generated in the system at high temperatures (around 100 degrees). Although these impurities are formed slowly, their accumulation over time can still affect the heat exchanger. Our company uses filters designed by Shanghai Lianjing Environmental Protection Technology Co., Ltd., with filter elements produced by PALL. As for the cleaning frequency, it is higher during the initial startup of the system or after major repairs, as the amount of iron particles in the pipes and system is higher at those times; cleaning is less frequent during normal operation. A pressure differential gauge can be installed at the inlet and outlet of the filter; cleaning can be carried out when the pressure difference reaches around 15 KPa. There is no need to implement backwashing, as this involves higher costs and more complex procedures. It’s perfectly fine to use a bypass route for a short period of time.
