The most effective methods and investment requirements for dehydrating vinyl chloride monomer at present
Thread Content
The most effective method and cost-effective approach for removing water from vinyl chloride monomer at present: the distillation and cooling equipment in our company is suffering from severe corrosion. We hope that experts in this field can help us solve this problem. Thank you!
On which side does corrosion occur in distillation cooling equipment? Water side or monomer side? Also, if the distillation corrosion is severe, then won’t the compressor be affected as well?~~~~~
I have never seen corrosion in the full condenser; I have seen corrosion in the tail cooler and the product cooler. Mainly, the coalescer provides better water removal effects; additionally, water is drained at regular intervals through separation.
The water separator continues to drain water at regular intervals, and alkali addition has been carried out after technical modifications behind the machine, but the results remain poor. I hope fellow users can offer some advice or share their experience with using aggregators
There are many posts on the HaiChuan Forum regarding efficient gas-liquid demisting and defoaming separators. Please visit www.novelenergytech.com to learn about the performance parameters, application records, and contact information of its airfoil-type high-efficiency gas-liquid demisting and defoaming separator.
Preferred method: molecular sieve pressure- and temperature-variable adsorption; secondly, spherical alkali drying.
The alkali replacement in the alkali washing tower isn’t done in a timely manner; analyze the alkali content in the tower more frequently and prepare alkali promptly. Is adding alkali behind the machine not taking into account the compressor’s impact?
Are there any recommended manufacturers for coalescing filters? I’m a bit interested in this area
It seems like this post is going to sink. . All these years have passed, and temperature-dependent adsorption dehydration has become highly mature; the water content in VCM produced by the calcium carbide method is below 100 ppm. Additionally, liquid-phase dehydration has also seen progress; it is said that levels can be reduced to below 100 ppm. I wonder if there are any better application technologies
