Description
Technical Field
The invention relates to a wellhead casing gas dehydration technology, in particular to a miniature wellhead casing gas dehydration device.
Background
The water content of the casing gas is one of main reasons for the problems of freezing and blocking of a gas pipeline, flameout of a heating furnace, insufficient combustion and the like, and the stable operation of the heating furnace is seriously influenced, so that the research on the casing gas dehydration technology needs to be urgently developed, the system stability and the combustion effect of the heating furnace are improved, and the important significance is realized on the guarantee of oil field production.
Moisture is an incombustible substance, which can cause low flue gas temperature of a fire tube, long combustion stroke and large incomplete combustion loss, so that dehydration of an air source is one of the keys for controlling emission. The dehydration method mainly comprises a solvent absorption method, a solid adsorption method, a low-temperature separation method, a membrane separation method and a supersonic speed method; gravity settling, inertial separation, fiber filtration separation, cyclone separation, and the like.
The solvent absorption method is a method for realizing dehydration of natural gas by carrying out gas-liquid mass transfer in an absorption tower by utilizing the characteristic that the solubility and absorption capacity of a dehydration solvent to water and natural gas are different, common absorbents mainly comprise Ethylene Glycol (EG), diethylene glycol (DEG), triethylene glycol (TEG) and the like, wherein triethylene glycol has a series of advantages of good thermal stability, easiness in regeneration and the like, and therefore triethylene glycol is widely used as the dehydration solvent in industry.
The solid adsorption method is a technological process for removing water vapor in a gas mixture by adopting the adsorption characteristic of a solid adsorbent to the water vapor, and can be divided into activated alumina dehydration, silica gel dehydration, molecular sieve dehydration and the like according to the difference of the types of the solid adsorbents.
The low-temperature separation method is characterized in that the natural gas mixture is reduced to a certain temperature by utilizing the different liquefaction temperatures of natural gas and steam, so that water in the natural gas mixture is condensed into liquid drops, the natural gas is still in a gaseous state, and the separation of the gas and the liquid drops is realized on the basis of the temperature reduction method.
The gas-liquid gravity settling separation is to realize gravity separation of two phases by using the density difference of the gas phase and the liquid phase, namely when the gravity borne by liquid drops is larger than the buoyancy of gas, the liquid drops settle out from the gas phase and are separated. It has simple structure, convenient manufacture and large operation elasticity, but needs longer retention time. Therefore, the separator is large, heavy, high in investment and poor in separation effect, and can only separate larger liquid drops, and the limit value of the separated liquid drops is usually 100 μm.
The inertial separation of gas and liquid is realized by making the gas flow turn rapidly or impact on baffle plate and then turn rapidly, so that the liquid drop movement track is different from that of gas flow to achieve separation. The device has the advantages of simple structure, large handling capacity, high gas velocity of 15-25 m/s generally, large resistance, larger suction force at a gas outlet to cause secondary entrainment, and poor separation effect on liquid drops with the particle size of less than 25 mu m.
Filtration separation is a separation method in which liquid droplets in a gas are separated by a filter medium. The core component is a filter element, preferably a wire mesh and fiberglass. When the gas flows through the screen structure, the liquid drops larger than the screen aperture are intercepted and separated. The filtering type gas-liquid separator has the advantages of high efficiency, capability of effectively separating small particles with the range of 0.1-10 mu m and the like; however, when the gas velocity is high, the amount of entrainment of liquid droplets in the gas increases, and there is a problem that the screen is difficult to clean.
The gravity separation space requirement is large, the separation effect is poor, and the limit value of the separated liquid drop is usually 100 mu m; the filtering separation can obtain higher separation efficiency, can effectively separate small particles in the range of 0.1-10 mu m, and has the problem that the silk screen is difficult to clean. The cyclone separation saves space, and the inertial separation can effectively separate 25 mu m liquid drops, so the best separation effect can be realized by using two-stage separation, wherein the cyclone separation is selected at the first stage and the inertial separation is selected at the second stage. For the gas-liquid separator, the current equipment has a relatively large processing capacity, and special research on separation equipment is needed for processing the casing gas with small flow and low pressure.
The invention patent with publication number CN 103285706A discloses a high-pressure separator for compressing and liquefying supercritical carbon dioxide of marsh gas, wherein a tubular upright post is arranged in the center of an inner cavity of the separator, and double spiral plates are fixed on the outer wall of the tubular upright post; the inner wall of the separator shell is provided with a diversion trench; the lower part of the inner cavity of the tubular upright post is provided with a pore plate, and fillers which are arranged in a ring shape are arranged below the pore plate; a liquid discharge hole is arranged at the inner side of the tubular upright post and close to the liquid discharge port, and an exhaust hole is arranged at the position close to the exhaust port; the upper part of the separator is provided with an air inlet. When the device works, a gas-liquid mixture of methane and carbon dioxide liquid enters the high-pressure separator from the air inlet in a tangential direction, and fluid performs centrifugal motion under the flow guide effect of the double spiral plates; because the mass and the speed of each particle in the mixture are different, the centrifugal force obtained by each particle is also different, the liquid particles with large centrifugal force can be quickly separated to the outer edge of the fluid, the particles with similar properties can be agglomerated into larger particles in the flowing of the gas-liquid mixture, the larger centrifugal force is obtained in the next spiral motion, and the liquid particles can be separated from the original running track and enter the diversion trench to flow downwards to the bottom under the action of the centrifugal force; the obtained gaseous particles with small centrifugal force can continuously do spiral motion along the spiral cavity and move to the exhaust port through the exhaust hole, so that gas-liquid separation is achieved. The unseparated gas-liquid mixture continuously flows downwards to enter the filler at the lower part of the inner cavity of the separator through the pore plate, the filler comprises a damping pipe, a steel wire ball and the like, in the area, the liquid carbon dioxide with high gravity falls downwards, the gas-liquid separation is further carried out, the finally separated liquid carbon dioxide enters the liquid discharge port through the liquid discharge hole to be discharged, and the gas passes through the gas discharge hole at the upper part of the upright post and then is discharged through the gas discharge port. The device aims to get rid of the traditional methane carbon dioxide separation mode, improves the separation efficiency on the basis of the traditional gas-liquid separator, is suitable for being installed in high-pressure equipment such as a methane compressor and the like for gas-liquid separation, can be used in common equipment, but has the disadvantages of complex relative structure, large volume, high cost, frequent replacement or filler cleaning and troublesome maintenance.
