Abstract
Volatile organic compounds and water vapor are recovered from a low-boiling gas by compressing the gas to an elevated pressure and cooling the gas in stages to condense volatile components and water while avoiding freezing in the system. Operating the system at an elevated pressure increases condensation efficiency, reduces the number of stages required, and minimizes operating problems to avoid freezing.
