Regarding product quality, the control of biuret
Thread Content
Due to insufficient steam usage. Maintain the high-pressure system at 80% load operation. However, the quality of the biuret index remained substandard, so the temperature of the liquid coming out of the stripping tower was later reduced to 171°C. The biuret content reached 0.87%. I would like to ask what the effects are of an excessively low bottom liquid temperature in a stripping tower?
This leads to an increase in low-pressure load, resulting in higher ammonia consumption by the system.
