The methanol exits the column as distillate, Stream 16. Stream 16 is then pumped up to 16.8 atm and recycled back to mix with fresh methanol, Stream 3 in vessel V-104.See all results for this question
What are the different types of distillation columns?
There are many types of distillation columns, each designed to perform specific types of separations, and each design differs in terms of complexity. In batch operation, the feed to the column is introduced batch-wise. That is, the column is charged with a 'batch' and then the distillation process is carried out.See all results for this questionUsing thermally coupled reactive distillation columns in distillation-column catalytic distillation column methanol p PaintingBoth the sequences are optimized by using the thermal and hydraulic analyses of the Column Targeting Tools of Aspen Plus simulator.

Purified methanol is produced by distilling a water methanol mixture in (a) a first column from which is taken a product methanol stream at an upper level, weakly aqueous methanol as a side stream and water as bottoms and (b) a second column in which that weakly aqueous methanol is separated into an overhead product stream and aqueous methanol bottoms. The first column may be preceded by a preliminary volatiles-removal column.The Etherification of Methanol and Isobutene in a distillation-column catalytic distillation column methanol p PaintingAug 31, 2002 · The optimal operating conditions for the catalytic distillation process are a pressure of 0.7 MPa, a methanol/isobutene feed molar ratio of 1, and a reflux ratio of more than 3.

Production of Formaldehyde from Methanol
The distillation column receives the liquid then separates the overhead methanol stream (68.3 oC, 1.2 atm) then recycles it back to methanol fresh feed mixing point. The bottom formaldehyde stream is pumped and mixed with deionized water forming (37 wt. % Production of Dimethyl EtherThe water and methanol exit as the bottoms stream, Stream 13. This stream is then throttled to 1 atm and then sent to T-103 where the water and methanol are separated. The water exits the bottom of the distillation column as Stream 15, and is sent to waste treatment. The methanol exits the column as distillate, Stream 16.
