Abstract
The invention discloses a method for storing natural gas. The method is realized by a natural gas storage technique consisting of a liquid storage tank, a liquid circulating pump, an adsorption tank, a molecular sieve dehydrator, a gas-liquid separator for natural gas, a compressor and a reducing valve. The method comprises the following steps: natural gas from a gas well or an oil well is subjected to pressure treatment to have the pressure reduced to 3.5 to 5 MPa or increased by the compressor to 3.5 to 5 MPa, and enters the gas-liquid separator for natural gas to undergo gas-liquid separation and then the molecular sieve dehydrator for dehydration and finally the adsorption tank to be absorbed by a natural gas absorbent; meanwhile, the liquid circulating pump is opened to remove absorption heat in time, and a gas vent valve of the absorption tank is opened after absorption is stable to fill gas to a pressure vessel of a user through an gas outlet; the liquid circulating pump continue circulating to provide heat for the separation of natural gas.
Description
One, technical field
The present invention relates to the method that a kind of rock gas stores, rock gas absorbing and storing technology is meant the special-purpose sorbent of the rock gas of the high-ratio surface of packing in gas holder, utilize its huge specific surface area and abundant pore structure, normal temperature, mesolow (＜6.0MPa) following rock gas is stored in the mode of adsorbing.
Two, background technique
Partly burnt by emptying at remote block oil field and offshore oilfield by the block rock gas that ship draws oil to produce, the rock gas produced of some block very " richness " particularly, methane content is about 65%, and CO
2, N
2Content is all less, as is recycled, will be higher than the value of general gas reservoir rock gas.
Because rock gas volume energy density is low, therefore, effective storage of rock gas is to promote the use of rock gas, particularly the important channel of natural gas vehicle refueling.In present existing compressed natural gas and LNG Liquefied natural gas, exist the pressure height, the flow process complexity, compression device, processing equipment and tankage are huge, and investment is big, floor space is big, potential safety hazard is big and the defective of difficult management.
Three, summary of the invention
The purpose of this invention is to provide the method that a kind of rock gas stores, the rock gas that solves above-mentioned prior art existence stores and invests greatly, cost is high and problem of environment pollution caused.
Technological scheme of the present invention realizes in the following manner:
The present invention realizes by the rock gas storage process of being made up of solution storage tank, solution circulation pump, adsorption tanks, molecular sieve dehydrator, rock gas gas-liquid separator, air compressor, reduction valve.
With gas well or oil well come rock gas, through the reduction valve 3.5Mpa-5Mpa that reduces pressure, or with compressor boost to 3.5Mpa-5Mpa, enter the gas-liquid separation of rock gas gas-liquid separator, enter the molecular sieve dehydrator dehydration again, enter adsorption tanks again,, adsorb with the special-purpose sorbent of rock gas, to open solution circulation pump simultaneously, heat of adsorption is cemented out timely, after treating that absorption is stable, open the valve of giving vent to anger of adsorption tanks, give the aerating of user's pressurized container by outlet, solution recycle system continues circulation, and resolving for rock gas in the adsorption tanks provides heat.Adsorption tanks are made as horizontal cylinder tank, on the right-hand member end socket, be provided with a rock gas import and a gas outlet, about be lined with one between the weld seam of two end sockets and filter cylinder, filter between cylinder and the adsorption tanks and be provided with annular space, between the two with supporting welding together.Be provided with a cartridge filter cover plate at the right-hand member that filters cylinder, be provided with an outlet in the bottom of cartridge filter cover plate; Establish a base plate at the left end of cartridge filter, be provided with fine filter opening in all sides of cartridge filter; Be provided with the Circulation pipe that cooling liquid turnover pipe is nested to cartridge filter right-hand member inside at end socket center, an adsorption tanks left side, the cooling liquid inlet pipe is interior, cooling liquid goes out pipe outside, is in the pipe periphery of filtering in the cylinder and evenly is welded with some blocks of circular heat radiation wing plates, between heat radiation wing plate acticarbon is installed; Acticarbon by petroleum coke and caustic potoash and potassium chloride or calcium chloride or sodium chloride by mass fraction than mixed that activator be formed caustic potoash: potassium chloride=10:1 or caustic potoash: calcium chloride=10:1 or caustic potoash: sodium chloride=10:1 makes activator; Petroleum coke and activator mass fraction be than 1:3-4, and put in the high-temperature reactor, is activated to 1-1.5 hour under 600 ℃-800 ℃, discharging cooling, washing, filter, dry, compression molding, make the active carbon with high specific surface area sorbent.
Through retrieval both at home and abroad, do not find the rock gas storage process identical as yet with the present invention, the present invention has realized the recovery of retail natural gas, environment has been protected in energy-saving and emission-reduction again.
Compared with the prior art the present invention has the following advantages:
(1) lower by (3.5～6.0MPa) because of its pressure store, less demanding to gas storage and charger withstand voltage properties, equipment needed thereby all can be realized production domesticization, and investment cost is low, charger only needs intermediate pressure compressor to get final product, and has saved the expense of building a station and the operating cost of gas-filling station greatly;
(2) mesolow uses its Safety performance of rock gas good down; In addition, natural gas-storing has advantages such as regular maintenance is convenient, operating cost is low under the mesolow condition.
(3) rock gas absorption stocking system little investment, easy to operate, the reliability height does not need additionaling power, so its operating cost is low.
