Short answer: With a significant reduction in gasification load, how should the low-temperature methanol washing system be adjusted? (1) Ensure that the methanol circulation rate matches the load ； (2) Pay attention to the liquid level in each tower; it should be kept as low as possible to prevent methanol from being carried away ； (3) Pay attention to pressure stability.

The load reduction process should not be carried out abruptly, whether in terms of increase or decrease; especially during the reduction phase, it should be done as slowly as possible. If the gasification furnace shuts down, the low-temperature methanol washing system must promptly reduce the amount of propylene and the amount of nitrogen used for stripping, and it should also use other adjustment methods to raise the temperature of methanol at the bottom of the methanol washing tower
