LOCK AND METHOD OF DEGASSING Russian patent published in 2015 - IPC C08F6/00 C08F6/10 B01J8/00 B01J19/00 F26B25/00 G05B17/00 G05B9/00 C08F10/02 C08F10/06 

FIELD: instrumentation.

SUBSTANCE: invention relates to polymer powder degassing. Lock is described for use during the polymer powder degassing in the degassing vessel. Lock includes temperature measurement of the polymer powder inside or at output of the degassing vessel. Comparison of the measured value with limit value to determine, weather the measured value exceeds the limit value or not. If the measured temperature is below the specified limit value executing of one or more actions directed to reduce concentration of the hydrocarbons in the polymer powder exiting the degassing vessel, and/or prevention of the polymer powder unloading from the vessel. Besides, the degassing method of the polymer powder in the degassing vessel is described.

EFFECT: assurance by system of determination locking of the increased hydrocarbons content leaving the degassing vessel, operating quickly, and easy in operation.
