Spray methanol
Thread Content
What are the advantages and disadvantages of using cold methanol or hot methanol for spraying?
It wasn’t hot methanol, was it? There is only a distinction between lean methanol and rich methanol, and hot methanol has a significant impact on the cooling capacity of the system.
Our facility uses hot lean methanol
If lean methanol is used, a small amount can be separated from the cold lean methanol in the upper absorption tower.
The main consideration is the impact on the material selection for coiled heat exchangers and methanol spray pipelines
Coiled tube heat exchangers and methanol pipelines are made of 304L stainless steel, so they are not affected by low temperatures.
The main consideration should be reducing the heat loss of the system and increasing the load on the ammonia chiller
Your suggestion is quite innovative; I wonder what the effect would be if cold methanol is used?
Spraying methanol is primarily used to lower the freezing point of the water in the shift gas, thereby preventing ice formation that could block the pipes
