Are there any other units whose synthesis towers use a cold shock method?
Thread Content
Our factory uses the cold-shock type, and we have filed for a patent
Hehe, could you please introduce the details of the equipment?
It’s not used very often in large installations; most of them are water-cooled.
Cold shock is commonly used in diol plants; I haven’t heard of it being used in monoalcohol plants. I don’t know what kind of device the original poster’s unit is, or what its capacity is What about the design and manufacturing unit? Share the good things with everyone: loveliness:
The cold-jump type is one of the earliest methanol synthesis reactors; there are still patents filed for it – that can’t be right, right? The newly installed methanol plants also don’t use the cold-shock type anymore!
What exactly is it like? What structure?
Our factory uses the cold-shock method; adjusting the tower temperature with this method can easily lead to large differences in temperature across the surface. It’s not very useful.
Our plant uses a cold-quenching method for methanol synthesis, and the equipment includes: a cold-quenching synthesis tower, a gas-to-gas heat exchanger, a methanol water cooler, a methanol separator, a flash tank, and a startup heating furnace.

With an annual production capacity of 200,000 tons, it requires 58 cubic meters of catalyst. Linfen, Shanxi. I hope we can strengthen communication and exchange. Phone ； 13994033019
For applications that do not require steam generation, a cold-jet tower type can be used; otherwise, a uniform-temperature heat transfer tower type (plate-and-shell or shell-and-tube) can be chosen.
From a thermodynamic perspective, the use of cold-quenching systems in synthesis towers is not conducive to energy utilization.
