Low-temperature methanol washing
Thread Content
Dear seniors in the chemical industry, may I ask how many columns are generally used in current low-temperature methanol washing processes?
Based on the gasification process you have in place and the final product structure of the plant, the methanol washing process and the selection of towers are ultimately determined. There are now 4.5.7.9.10.11 tower processes.
Is there a process flow diagram for the seven towers? Which seven towers are included?
Dalian also has an eight-tower process, with multiple circulating methanol flash towers.
Look at the applications; more flash tanks are needed for ammonia synthesis production, and we use 8 towers
Based on production requirements and product specifications, the five-tower process is a classic methanol washing process
The latest Linde process uses 6 towers, and Dalian University of Technology also employs 6 towers.
It is generally a seven-tower process (including the ammonia scrubber tower); strictly speaking, it is a sulfur tower process
Luchi and Lind Five Towers are the most common, six, seven, nine. . . . All of these are available; the Liantong University Six Towers model is the most common.
The 6-tower process from Dalian University of Technology is adopted. Classify the ammonia scrubber as part of the conversion system equipment
The process flow at Dalian University of Technology, including the ammonia washing tower, consists of 8 towers.
