APPARATUS FOR FILTERING AND SAMPLING LIQUIDS IN PRESSURE VESSELS Russian patent published in 2015 - IPC G01N1/10 

FIELD: chemistry.

SUBSTANCE: apparatus includes a receptacle in the form of a sealed container whose lower part is fitted with a controlled two-way diaphragm valve, and a nozzle for feeding water used to wash the sample delivery line. The apparatus also includes a filter element, which is hermetically connected to a filtrate storage container, and an information control, display and transmission unit. The filter element is located in the working medium and is mounted on the sample removal line. To regenerate the filter surface, the apparatus includes a hydraulic pressure pulsator, which is installed on the sample removal line between a ball valve and a resistance disc, through which the sample is fed into the sample receptacle in the form of a sealed container, having a water-cooled jacket located at the end of the filtrate removal line.

EFFECT: invention improves the accuracy of monitoring process parameters, provides timely detection and rectification of process disorders, which enable to obtain more reliable data on the chemical composition of a solution.
