The importance of hydrogenation air cooler

The lower the air-cooling outlet temperature, the smaller the linear velocity of the gas in the high temperature range, and the less likely it is to carry liquid.； The higher the outlet temperature, the opposite is true. Control the air cooling outlet temperature to be too low and increase energy consumption ； The higher the outlet temperature of the high-pressure air cooler, that is, the higher the inlet temperature of the heating furnace, the higher the heat load of the heating furnace and the energy consumption. However, it is not that the higher the high-pressure air cooling outlet temperature, the better. Excessive high temperature causes an increase in linear speed and liquid volume, which is not conducive to the safe operation of the circulating hydrogen compressor. The purpose of controlling the outlet temperature of the high-pressure air cooler to ≤50°C (design) is to prevent the high linear velocity of the gas from being too large and entraining liquid to destroy the cycle. For devices designed to circulate hydrogen desulfurization, the high-pressure air-cooling outlet temperature is too high, causing hydrocarbons carried in the circulating hydrogen to cause the amine liquid to foam, and the desulfurization effect becomes worse. In severe cases, circulating hydrogen liquid will appear, affecting the safe operation of the hydrogen circulation machine.

The high-pressure air cooling outlet temperature is too high, and the circulating hydrogen carries liquid, which affects the safe operation of the hydrogen circulation machine.
