Scrubber Device for Scrubbing Hydrocarbon Gas Stream Including Modified Sparger Ducts

A gas scrubber device for separating produced hydrocarbon fluids into collected liquids and a gas stream, and for scrubbing a waste gas from the gas stream using a scrubbing solution, the device comprising:

• a scrubbing chamber arranged to contain an operating level of the scrubbing solution therein;
• a manifold having a gas inlet arranged to receive the gas stream into the manifold;
• at least one sparger duct supported within the scrubbing chamber in communication with the manifold to receive the gas stream from the manifold, in which the sparger duct includes a plurality of discharge openings formed therein below the operating level of the scrubbing solution so as to be arranged to discharge the gas stream into the scrubbing solution in the scrubbing chamber;
• a discharge passage in communication with the scrubbing chamber above the operating level of the scrubbing solution so as to be arranged to discharge the gas stream from the scrubbing chamber subsequent to the gas stream passing through the scrubbing solution;
• a liquid collection tank arranged to collect a maximum level of the collected liquids therein;
• a flow inlet coupled to the liquid collection tank at a level above the maximum level so as to be arranged to receive the produced hydrocarbon fluids into the liquid collection tank through the flow inlet for separation of the gas stream from the collected liquids in the liquid collection tank;
• a gas passage coupled between (i) the liquid collection tank above the maximum level and (ii) the gas inlet of the manifold so as to be arranged to direct the gas stream from the gas separator to the gas inlet of the manifold;
• and
• a drain line connected between the scrubbing chamber below the operating level of the scrubbing solution and the liquid collection tank, the drain line including a valve connected in line with the drain line to selectively open and close the drain line.
