Temperature control
Thread Content
One of the reactions is exothermic; for a while, the reaction temperature is kept between 40 and 50 degrees. However, due to the heat released by the reaction, the steam temperature rises, and combined with this heat, the temperature quickly exceeds 50 degrees. We are now looking for ways to control this situation: 1. Install a pressure gauge in the jacket to maintain the steam pressure at around 2 units. The reaction proceeds at a temperature of 40–50 degrees, after which the steam flow is increased so that the reaction can continue at temperatures above 50 degrees. 2 Use hot water to raise the temperature to 45-48 degrees; after reacting for a while, drain the hot water and use steam to raise the temperature. It seems that Method 1 places high demands on the operators. 2 The method is very cumbersome. I lean toward the first method. . Do anyone have any suggestions?
Reply to 1# zyp0009928: Why use steam for heating? Can’t we use a constant warm water system to heat it instead? The heat released by the reaction can be removed using a warm water system
