Apparatus for separating gas from a liquid

A methanol and nitrogen charged hardened furnace system including a furnace located within a heated building in combination with a liquid methanol supply tank for supplying liquid methanol to said furnace and said tank being pressurized with nitrogen and connected to said furnace by a piping system from said tank through said building to said furnace, comprising a high pressure flow line from said pressurized methanol tank passing through said building to immediately adjacent said furnace, said pressurized methanol tank including nitrogen from said pressurized nitrogen, a pressure regulator connected to said high pressure line and establishing a low pressure output flow line, a methanol gas debubbler unit connected to said low pressure line and having antigen degassed methanol output line, a flowmeter connected to said debubbler connected to said low pressure line and having a flow-positioned float member positioned within a flow passageway in accordance with the flow rate through said meter, said meter having a readout unit coupled to said flow chamber communicating with said flow passageway with said float extending downwardly into said float chamber, said piping system including a low pressure line connecting the output of said flowmeter to said furnace and including means for adjusting the flow of methanol to said furnace in accordance with the output of said flow meter, said debubbler unit including a sealed housing having an inlet passage connector connected to said pressure regulator and a bottom liquid outlet connected to said flowmeter whereby said sealed housing establishes a pressurized chamber for transfer of methanol to said flowmeter, said inlet passage connector and said bottom liquid outlet are constructed and arranged such that the flow of liquid into said sealed housing is selectively greater than the flow through said liquid outlet to thereby enable said bottom liquid to accumulate in said vessel, and said sealed housing having a gas release unit including a gas outlet connected to the upper end portion of the housing above said inlet passage connector, said housing accumulating liquid methanol in the bottom portion of the housing, nitrogen gas in said methanol being released in gaseous form and accumulating as nitrogen gas within the upper end portion of said housing, and an operating unit coupled to said gas release unit and nitrogen gas within said pressurized housing and responsive to a selected accumulation of said nitrogen gas and lowering of the level of methanol to actuate said gas release unit for a momentary period to release said pressurized accumulated nitrogen gas through said gas outlet from said pressurized chamber.
