What is the difference between cold low-score and hot low-score operations? Thank you
I don’t understand what it means! Put it more simply.
When operating at high temperatures, pay attention to the following: 1. Liquid level: If it is too low, the safety valve will activate. 2. Inlet temperature: It should not be too high, as this will cause liquid formation in the cold fraction, affecting the quality of the circulating hydrogen as well as subsequent operations. Special attention must be paid to the cold low fraction. 1. Phase boundary: Sulfur-containing wastewater present in the cold low fraction needs to be removed promptly. 2. Inlet temperature: A too high inlet temperature results in an excessive amount of gaseous components, which is not desirable.
