What is the importance of the methanol liquid discharge valve at the bottom of the separator? The methanol liquid discharge valve located at the bottom of the separator is a throttle valve that operates under a significant pressure difference; the area ahead of the valve is the high-pressure synthesis zone, while the area behind the valve contains methanol at a low pressure of 0.3–0.6 Mpa. This valve serves as the boundary between the high-pressure and low-pressure zones of the synthesis system, which is why its control position is extremely important. An excessive opening can lead to too low a liquid level in the separator, gas leakage between high and low pressure systems, and overpressure in the expansion tank ; If the opening is too small and the level of liquid in the separator is too high, it can lead to accidents involving liquid carryover. This valve is constantly exposed to liquid methanol during the production process; over time, internal leakage may occur, which can affect the control of the liquid level. It should be inspected and maintained after shutdown.
