The operating pressure issue in the methanol regeneration tower of Linde’s low-temperature methanol washing process
Thread Content
I would like to ask the experts: What determines the operating pressure of the regeneration tower in Linde’s low-temperature methanol washing process? What is the general control level? In our facility, the value is kept at 0.27. If the sulfur recovery unit is not taken into account, does a lower pressure in the regeneration tower mean greater energy savings?
The pressure in the regeneration tower depends on the degree of regeneration of the solution as well as its water content; if these two factors are under control, it is preferable to have a lower temperature.
Operating temperature: 101.99–90.79°C Operating pressure: 0.37–0.33 MPa(A)
Our company uses NHD desulfurization, with a temperature of 147 degrees and a pressure of 0.09 MPa
