On the issue of absorbing hydrogen sulfide with lean liquid
Thread Content
Low-temperature and high-pressure conditions are more favorable for the lean liquid to absorb hydrogen sulfide; then why is it still necessary to insulate the lean liquid line? Some systems even include heaters for the lean liquid, and its freezing point is also very low.
The temperature in the low-amine night phase is not the lower the better; during hydrogenation, it is necessary to control the temperature difference between the amine solution and the absorbed gas. It is optimal for the amine solution temperature to be 4-6 degrees higher than the gas temperature. It is to prevent the light oil in the gas from condensing in the amine solution.
