FIELD: process engineering.
SUBSTANCE: invention relates to polymer powder degassing. It describes the blocking to be used in degassing of polymer powder inside degassing vessel. Measured is temperature of gas phase obtained at separation of fluid and vapour to be used as purging gas in said degassing vessel. Then, said temperature is compared with threshold magnitude. In case measured temperature is higher than threshold magnitude degree of vapour application as purging gas application is terminated or decreased. Besides, said blocking includes fluid level, vapour phase pressure and temperature are measured. Polymer powder degassing is described.
EFFECT: perfected system of control over quality of return purging gas, reliable and simple system.
