Description
Technical field
The utility model relates to oil recovery technique field, oil field, particularly a kind of analogue means of crude oil accompanying gas detection.
Background technology
Hydrogen sulfide is the extremely strong toxic gas of a kind of harmfulness, when containing low in hydrogen sulphide in the air, can work the mischief to the person, can produce life harm when concentration reaches certain value, so hydrogen sulfide is one of important hidden danger of safety in production.The hydrogen sulfide gas that contains in some oil field produced crude oil, the point of release of hydrogen sulfide gas is a lot, follows a plurality of positions of crude oil production and link, crude oil storage tank open position such as particularly all kinds of storage tank gauge hatch, breather valve.Discharge in a large number because oil storage tank heating causes in the crude oil solubilised state hydrogen sulfide to be converted into gas, open wide device by tank deck and be released into atmosphere, employee's person is caused potential danger.But be to efflux just in a organized way by associated gas gases such as hydrogen sulfide are transferred to other zone at oil storage tank associated gas hydrogen sulfide administration way at present, fundamentally do not eliminate safe hidden trouble, still have potential risk.
Therefore very important to the improvement of oil storage tank associated gas hydrogen sulfide, particularly at oil storage tank mouth association air chamber, context of detection does not also have practical analogue means.
The utility model content
The purpose of this utility model is: a kind of crude oil storage tank mouth associated gas hydrogen sulfide absorption analogue means is provided, can simulates under different component associated gas composition, associated gas different flow, different water cut, the different temperatures desulfurizing agent fast to hydrogen sulfide removal efficient in the laboratory; Realize indoorly to the desulfuration efficiency evaluation, research simultaneously forms the accompanying gas with crude oil release characteristic, improves the hydrogen sulfide regulation effect.
The technical solution adopted in the utility model is: crude oil storage tank mouth associated gas hydrogen sulfide absorption analogue means, mainly form by gas cylinder, pressure-reducing valve, needle valve, spinner flowmeter, gas blending tank, drying tower, adsorption tower, pressure-measuring device, temperature measuring set, safety valve, concentration of hydrogen sulfide analytical instrument and vent gas treatment jar, it is characterized in that: described gas cylinder has two, one of them gas cylinder is equipped with hydrogen sulfide standard gas, and a gas cylinder is equipped with accompanying gas with crude oil; Outlet at two gas cylinders is in series with pressure-reducing valve, needle valve and spinner flowmeter respectively; The other end of spinner flowmeter connects the inlet of gas blending tank respectively by pipeline.Two needle valves are controlled gas flow respectively, open back gas and feed in the gas blending tank through spinner flowmeter, and two kinds of gases fully mix in the gas blending tank.The gas blending tank is connected with pressure-measuring device, temperature measuring set and safety valve by pipeline, can measure the pressure and temperature of gas in the gas blending tank.Be in series with drying tower and adsorption tower on the outlet line of gas blending tank, have pipeline to connect the inlet of concentration of hydrogen sulfide analytical instrument in the outlet of adsorption tower, the outlet of concentration of hydrogen sulfide analytical instrument connects the vent gas treatment jar by pipeline; The outlet of safety valve connects the vent gas treatment jar by pipeline.Emit from the gas blending tank through even mixed gas, by the drying tower drying, lead to adsorption tower again, gas falls hydrogen sulfide stripping to the suction-operated of hydrogen sulfide through desulfurizing agent in adsorption tower; The gas behind the adsorption tower of flowing through enters the concentration of hydrogen sulfide analytical instrument and analyzes, and discharges gas from the concentration of hydrogen sulfide analytical instrument and is introduced into the vent gas treatment jar by pipeline, removes the hydrogen sulfide gas that is not adsorbed in the gas.
Desulfurizing agent is housed in the adsorption tower.In the gas blending tank flow-stopping plate is set, increases the time that gas is flowed through in jar, the import of gas and outlet all be arranged on the gas blending tank on cover.Described pipeline adopts lucite tube; Pressure-reducing valve, needle valve, spinner flowmeter valve must have the anti-H 2 S antiseptic property.
The beneficial effects of the utility model: the utility model crude oil storage tank mouth associated gas hydrogen sulfide absorption analogue means, can in the laboratory, simulate under different component associated gas composition, associated gas different flow, different water cut, the different temperatures desulfurizing agent fast to hydrogen sulfide removal efficient, realize indoor to the desulfuration efficiency evaluation, research simultaneously forms the accompanying gas with crude oil release characteristic, and efficiently and effectively improves the hydrogen sulfide regulation effect.
