Howdy. I'm not sure I understand your question but I'll do the best I can with the information you provided. The tool is ProMax which has Visio embedded into our product. You would use the Column Block to do most of that work.
For the last distillation column, water gets released at the bottom as a liquid and 98% methanol vapor is released at the top and is directed to the recycle stream. How does it exactly turn into a liquid stream to mix with the liquid methanol feed?
Assuming you are referring to slide 4 of the presentation, the methanol recovered as overhead product from the methanol recovery tower is completely condensed. Part of the liquid is used as reflux to the column, the rest is the recovered methanol that is recycled back to the front of the process. Thus, there is no vapor in the stream that is recycled back to the front.
@@BRE_ProMax and on the same slide of the presentation, after the reactive distillation column, the condensed MeOH and butene azeotrope is cooled further by a cooler and gets sent to the water wash column. does the MeOH butene mix stay as a condensed liquid when entering the water wash column?
@@modimoussa33 The overhead vapor is run through a heat exchanger where the vapor is cooled until is condenses. This is how the liquid is formed. If you need to know the exact physical processes of how condensation works, we recommend that you look into topics like “states of matter”, or “physical changes”.
@@BRE_ProMax I understand how the liquid is formed, but my question was if the overhead, after condensation, stays as a liquid when entering the water wash column
@@modimoussa33 The Water Wash Column in the drawing is a liquid/liquid contactor. There is no vapor present in the column at all. Water is the heavy liquid that goes in the top and comes out the bottom, while the unreacted butanes are the light liquid that goes in the bottom and out the top. The water wash is primarily present to remove the methanol in the unreacted butanes so that the unreacted methanol can be recycled an make the MTBE process more efficient and less costly.
In the reactive distillation process for the production of MTBE, the overhead product is an azeotrope of unreacted C4 components and methanol. The methanol concentration in the feed to the column is carefully controlled so that the azeotrope (collected as the top product) contains the bulk of unreacted methanol, and the MTBE is taken as the bottoms product.
Extremely Helpful. Thank you
What is the tool you use for the design of the reactive column? visio only?

Can you provide ma related Research papers for the production of MTBE and Books its My Final year Project
Ahsan Ali, please contact us at support@bre.com for further help.
why is MTBE the bottem product of the reactive destillation column and not methanol because the boiling point of methanol is higher then MTBE?
In the reactive distillation process for the production of MTBE, the overhead product is an azeotrope of unreacted C4 components and methanol. The methanol concentration in the feed to the column is carefully controlled so that the azeotrope (collected as the top product) contains the bulk of unreacted methanol, and the MTBE is taken as the bottoms product.
