Regenerator pressure
Thread Content
What is the normal control range for the regenerator pressure? What is the difference between the pressure in the settler and the pressure in the fractionator? What is the normal opening degree of the double-acting slide valve in the regenerator?
For questions of this type, it is best to consult the operating procedures for your specific position and equipment, as those are the guidelines you should know and master, along with the relevant standard specifications. Equipment models vary, as do the process procedures. The best answer is in your job operation procedures. If there is anything unclear, please send the relevant details such as the name, model, purpose, and a clear description of the issue, so that it is easier for everyone to discuss it. (For reference on feasibility)
Indeed, one should check their own operating procedures; since the scale and process of the equipment vary, there can sometimes be differences in various parameters.
The regeneration pressure is determined by the distillation pressure, which in turn is determined by the properties of the feedstock and the product distribution； The differential pressure between the settler and the fractionation tower is determined by the design parameters of the fractionation tower ； It is easier to operate when the opening degree of both valves is controlled at around 10%.
