PLANT FOR DETERMINING DISPERSE PHASE CONTENT IN GAS FLOW Russian patent published in 2013 - IPC G01F13/00 

FIELD: measurement equipment.

SUBSTANCE: plant for determining disperse phase content in gas flow includes a sampling probe, a separation unit containing a separator equipped with an element filter and a batch metre for liquid separated from gas. The plant also includes a unit for maintaining constant gas flow rate at the pressure, temperature and velocity in the plant system which are equal to pressure, temperature and velocity of gas flow, which includes a gas flow rate control valve, a flow metre and a supply assembly of hydrating inhibitor. Hydrating inhibitor supply assembly includes an inhibitor tank and an inhibitor supply valve to the gas flow rate control valve. In addition, the plant includes a filtration unit that is installed parallel to the separation unit between the sampling probe and the flow metre. The filtration unit includes an element filter for collection of moisture released at the pressure in the device system, which is equal to gas flow rate pressure; then, the element filter for collection of drop moisture and mechanical impurities from gas, and after it, an element filter for correction of measurement results. With that, the constant gas flow rate maintaining unit includes a mass flow metre as a flow metre, which is installed before the gas flow rate control valve.

EFFECT: obtaining the value of content of disperse phase in gas flow at short time of high-accuracy gas sampling, both at its high, and low content.
