Calculation method for the methanol extraction tower in MTBE plants
Thread Content
I would like to ask the experts here about the methods for calculating extraction towers. It seems that there are no good calculation software tools available in China for designing such towers; people mainly rely on experience, but the values obtained from experience vary. Whether it’s extraction towers used for aromatic hydrocarbon extraction or methanol extraction towers for Mtbe, I would like to know what parameters people take into account and what values they use. I hope to discuss the calculation of extraction towers in detail through this post; I appreciate any guidance you can provide! For our MTBE, the main parameters we consider are specific load and valve orifice velocity; the value for specific load is around 20, while the valve orifice velocity is around 25 cm. However, sometimes these two values conflict – how should we deal with that?
Reply to 1# wulove0222: We generally don’t use data such as valve orifice velocity here; instead, we use other reference values. We have built quite a number of MTBE plants here. In addition, we have also developed plants for producing isobutylene from MTBE as a raw material, and the calculations performed in such cases are quite accurate.
Use a packed tower directly; a few theoretical plates are sufficient. You can simply contact the patent holder to inquire about the price
This facility for producing isobutylene using MTBE as a raw material is something I’ve heard of for the first time; could you tell me where such a facility can be found? What is the process?
