Alfa Laval Compabloc helps solve problems for Sayanchimplast, Russia
Sayanchimplast, a leading Russian producer of vinyl chloride monomer (VCM), is always on the lookout for new ways to make their processes more efficient. Compabloc was installed in the purification column of the EDC/VCM plant before the cracker approximately one year ago.

A prime example is the ingenious solution they designed for reusing process vapors to heat a reboiler in their EDC/VCM process. There was only one problem: the shell-and-tube heat exchanger in the reboiler position clogged up so fast that the redesign – and substantial potential savings – were in danger of being abandoned. Until Sayanchimplast talked to Alfa Laval about Compabloc.
A Compabloc was installed in the purification column of the EDC/VCM plant before the cracker approximately one year ago. It’s used as a reboiler for the column still. The heating media is liquid EDC, a bottom product of the other rectifying column, with a temperature of 160°C.
