Abstract
Provided is a method for cooling a methanol r synthesis reactor effluent vapor stream in a methanol production plant, wherein the method comprises the steps of: receiving, using an inlet of a cooler, the methanol synthesis reactor effluent vapor stream from an interchanger or a methanol synthesis reactor of the methanol production plant; and spraying, using a recirculation pump connected to a spraying device, a liquid condensate received from a methanol synthesis loop onto a tube sheet of the cooler which enables direct contact of the liquid condensate with the methanol synthesis reactor effluent vapor stream and cools the methanol synthesis reactor effluent vapor stream.
Claims18
A cooling system for cooling a methanol synthesis reactor effluent vapor stream in a methanol production plant, wherein the cooling system is integrated with the methanol production plant, wherein the cooling system comprises:
- a cooler, the cooler comprising a tube and shell heat exchanger, comprising cooling tubes for cooling the methanol synthesis reactor effluent vapor stream, a shell side for passing of a fluid cooling medium, a tube sheet for separating the cooling tubes from the shell side, and an inlet that receives the methanol synthesis reactor effluent vapor stream from an interchanger or from a methanol synthesis reactor of the methanol production plant;
- and
- a recirculation pump connected to a spraying device that is configured to spray a liquid condensate received from a methanol synthesis loop onto the tube sheet of the cooler which enables direct contact of the liquid condensate with the methanol synthesis reactor effluent vapor stream and cools the methanol synthesis reactor effluent vapor stream,
- wherein the cooling system further comprises a vapor-liquid separator for separating a liquid condensate stream and a residual gas stream from the cooled methanol synthesis reactor effluent vapor stream.
