Oligomers keep entering the vacuum system of our unit (two screw compressors and two Roots compressors). Is there any way to remove these oligomers at the upstream stage? We’re currently using a shell-and-tube heat exchanger; the condensation collects inside the tube side, making it difficult to clean. Could everyone give some suggestions?

Low-temperature cooling, with a coil heat exchanger at the front end
A buffer tank can be added ahead to collect oligomers; if the system is large, a spray device can be considered
1. Adjust the vacuum pressure to control the vaporization of oligomers； 2. Subcooling and liquid separation tank after vaporization.
