摘要:
The cooling coils used in a commercial oxidation or ammoxidation reactors can be made more closely packed by providing the individual courses defining the cooling coil in a transverse arrangement rather than a linear alignment.
摘要:
A process for cooling quench effluent includes providing a quench column effluent to a quench column aftercooler condensate; cooling the quench column effluent to provide a quench column aftercooler condensate; and recirculating at least a portion of the quench column aftercooler condensate to the quench column aftercooler at a rate to prevent fouling of the quench column aftercooler.

摘要:
An extractive distillation process includes providing a mixture that includes acrylonitrile and acetonitrile to at least one distillation column; contacting the mixture that includes acrylonitrile and acetonitrile with aqueous solvent to provide an acrylonitrile-water azeotrope; and separating the acrylonitrile-water azeotrope from the acetonitrile to provide an overhead stream and a sidestream. The process includes controlling overhead stream impurities and sidestream impurities using a flow of the aqueous solvent added to the distillation column and a temperature of the distillation column.
