Working principle of the gas-liquid separator for hydrogen production from methanol

Gas entering the pump can cause cavitation; the oil sump at a higher level serves to supply oil, as well as to remove small molecules such as water that are generated during the circulation process

1. The oil-gas separator is a device used to remove gases from the heat transfer oil system. 2. The structure is simple; I have seen cases where pipes with a diameter one size larger than that of the main pipe were used for welding. The separation principle is centrifugal separation. 3. The function of the high-level tank is to accommodate the expansion volume of the heat transfer oil system.

The high-level tank (also known as the expansion tank) of the methanol cracking hydrogen production heat transfer oil system serves three main functions: 1. Oil filling at a high level. During initial operation of the machine, oil injection and exhaust in the system are primarily achieved through the pressure difference created by the high-level tank. 2. Compensation during heating and cooling processes. During the heating process from room temperature to above 200 degrees Celsius, the heat transfer oil expands to some extent; whereas when the system is shut down and the temperature drops, the volume of the heat transfer oil contracts. Compensation for these changes is achieved through the space in the overhead tank. 3. Boil the oil to release vapor. The new heat transfer oil contains a certain amount of moisture and light oil components, so oil boiling is required. During the heating process, water and light oil components gradually evaporate and enter tangentially at the oil-gas separator, where centrifugal separation takes place; the liquid remains in the heat transfer oil circulation system, while water vapor and oil-gas mixtures rise and are discharged into the overhead tank.
