Operating pressure control issues
Thread Content
In chemical production, many production equipment have their own operating pressure. Is this operating pressure the gauge pressure within the equipment? To make a certain reaction proceed under a certain operating pressure, how do you generally keep the pressure in the equipment constant? :handshake
This depends on the design description of the equipment, which generally refers to the gauge pressure within the equipment. To maintain the pressure of the equipment, one is to control the filling coefficient of the equipment, which is the volume. The other is to control the temperature of the medium in the equipment. The third is to pay attention to the chemical properties of the medium.
1. In chemical production, many production equipment have their own operating pressure. Is this operating pressure the gauge pressure in the equipment? answer: Yes 2. To make a certain reaction proceed under a certain operating pressure, how to keep the pressure in the equipment constant? answer: The pressure change caused by the reaction can be changed by changing the reaction rate (such as adding terminator\cooling, etc.), or opening the atmospheric phase outlet valve.
How to control equipment pressure is a huge topic. It depends on the equipment or reaction. For continuous reaction furnaces, maintaining the flow rate, temperature, and pressure of the reactants can stabilize the pressure.； For intermittent reaction kettles, the reaction formula is fixed. By removing the heat of the reaction in time, the pressure can be controlled without large fluctuations. ； It is even possible to stabilize the equipment pressure by controlling the transfer rate of the product, such as the size of the outlet and return flow.
