CONDENSED LIQUID SAMPLING APPARATUS, AND CONDENSED LIQUID SAMPLING METHOD USING THE SAME

PROBLEM TO BE SOLVED: To sample a condensed liquid at a clear condensation ratio by a method wherein process steam is introduced into a pressure container for a fixed period of time, a part thereof is condensed to determine the amount of a liquid and non-condensed steam is sufficiently cooled by a cooler to determine the amount of the condensed liquid. SOLUTION: With pressure adjusting valves V1-V3 closed, the apparatus is connected to a steam sampling line and the pressure adjusting valves V1 and V2 are gradually opened to adjust an internal pressure of a pressure proof container A. The pressure adjusting valve V3 is opened and then, closed after checking the discharging of the condensed water into the pressure proof container A. Processed steam is made to pass through the pressure proof container A for a specified time length, while the steam is cooled by a cooler C1 to measure the amount of the liquid L1. After a specified time passes, the pressure adjusting valves V1 and V2 are closed to measure a condensed liquid L2 accumulated in the pressure proof container A from the pressure adjusting valve V3 and a condensation rate is determined based on the amounts of the liquids L1 and L2. This measurement is repeated by varying the internal pressure of the pressureproof container A adjusting the pressure adjusting valves V1 and V2. This enables sampling of condensed liquids with different condensation ratios.
