Abstract
The utility model relates to a natural gas dehumidification device which is composed of a pipeline, a heat exchanger and a cooling water tank, the utility model is characterized in that the natural gas transmission pipeline is connected with the heat exchanger which is arranged in the cooling water tank, the lower part of the heat exchanger is provided with a light oil outlet, the light oil outlet is connected with a transmission pump, the cooling water tank has a volume of 10-200 cubic meter, the cooling water tank is made of reinforced concrete and is arranged under the ground. The natural gas dehumidification device has the advantages of reducing the investment of cooling equipments and the consumption of electric energy, and simplifying the flow process of the natural gas dehumidification, and also improving heat exchange and dehumidification effect so as to reinforce the reliability of natural gas operation.
Description
Technical field
The utility model relates to Natural gas extraction, storing technology field, particularly a kind of dehydrating unit of Sweet natural gas.
Background technology
The Sweet natural gas dehumidifying is meant in gas extraction, storage process, and the lightweight oil liquefaction condensation that is mingled with in the Sweet natural gas is come out.
At present, the way that the Sweet natural gas dehumidifying is adopted is: heat exchanger and spray column are installed on the transport pipe of Sweet natural gas, water coolant is sent into spray column, the heat transferred water coolant of Sweet natural gas, Sweet natural gas in the heat exchanger is cooled off, thereby the lightweight oil liquefaction in the Sweet natural gas is separated out.
This mode not only needs infusion of financial resources to purchase the spray column cooling tower, and not only consume a large amount of electric energy when summer environment temperature is high, and cooling performance is also very poor, the lightweight oil that Sweet natural gas the contains condensation of can not liquefying well.
Chinese patent, notification number is 2666916, discloses a kind of low pressure reduction throttling natural gas condensate and has removed device.This device is made up of gas-liquid separator, methanol dropping device, plate-fin heat exchanger, throttling valve, filter separator.Unstripped gas is through gas-liquid separator separates, the output terminal of gas-liquid separator is connected with the plate-fin heat exchanger input terminus, the plate-fin heat exchanger output terminal enters the filter separator input terminus behind throttling valve, the filter separator output terminal has been handled the gas input terminus with plate-fin heat exchanger and has been connected, and has handled the output of gas output terminal from plate-fin heat exchanger.But the equipment more complicated consumes a large amount of electric energy equally.
Summary of the invention
Have Sweet natural gas dehumidifying technology equipment complexity now in order to overcome, the deficiency that consumed power is many, the utility model provides a kind of Sweet natural gas dehydrating unit.This Sweet natural gas dehydrating unit can not only be removed the lightweight oil liquefaction condensation that contains in the Sweet natural gas and come out, and improves cooling, effect on moisture extraction, reduces power consumption, reduces investment.
The technical solution adopted in the utility model is: natural gas pipeline is connected with interchanger, interchanger is fixed in the cooling basin of filling clear water, the heat transferred water of Sweet natural gas, water passes to the earth with heat through concrete, or takes away heat by evaporation of water.The outlet of lightweight fluid is arranged in the bottom of interchanger, and the outlet of lightweight fluid connects transferpump.
In order to carry out the temperature of heat exchange and maintenance water pool inner water effectively, the volume of cooling basin should be at the 10-200 cubic meter.
In order not take ground, the cooling basin can adopt Steel Concrete to make, and the cooling basin is arranged on underground.
The beneficial effects of the utility model: adopt the utility model Sweet natural gas dehydrating unit, can reduce the cooling apparatus investment, reduce power consumption, simplify Sweet natural gas dehumidifying flow process, can improve heat exchange, effect on moisture extraction again.Because it is underground that the cooling basin is arranged on, and produced beyond thought effect, improved the safe reliability of Sweet natural gas operation.This Sweet natural gas dehydrating unit can be widely used in the Sweet natural gas dehumidifying at recover the oil station, oil gas combination treatment station.Because the oil gas treatment station requires distance bigger to fire safety, all there are enough spatial construction cooling basins at each station, has promotion prospect widely.Do not need procuring equipment, as long as build enough heat interchanging areas cooling basin.
Said structure of the present utility model has bigger improvement, makes on its practicality and the manufacturing cost, all meets the needs of Sweet natural gas industry fully, produces positive effect.It is a new and innovative, progressive, practical new design.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Description of drawings
Accompanying drawing is the utility model structural profile synoptic diagram.Being the structural representation of embodiment, is not full content of the present utility model.The direction of arrow indication is the direction of lightweight oil output.
Among the figure, 1. gas-holder, 2. pipeline, 3. interchanger, 4. pipeline, 5. transferpump, 6. cooling basin, 7. water, 8. lightweight oil outlet.
Embodiment
Embodiment: consult accompanying drawing.A kind of Sweet natural gas dehydrating unit of the utility model, 150 millimeters of natural gas pipeline (2,4) diameters.Cooling basin (6) adopts Steel Concrete to make, and cooling basin (6) are arranged on underground.The volume of cooling basin (6) should be 100 cubic metres.Natural gas pipeline (2,4) is connected with interchanger (3), and interchanger (3) is fixed on (6) in the cooling basin.Lightweight fluid outlet (8) is arranged in the bottom of interchanger (3), and diameter is 30 millimeters.Store water coolant (7) in the cooling basin (6).Lightweight fluid outlet (8) is connected with a centrifugal transferpump (5).
The Sweet natural gas that has lightweight oil enters interchanger (3) from pipeline (4), and process interchanger (3) and pipeline (2) are transported to gas-holder (1) and store.When Sweet natural gas passed through interchanger (3), because back interchanger (3) is immersed in the water coolant (7), Sweet natural gas passed through interchanger (3) with heat transferred water (7).Lightweight oil liquefaction condensation in the Sweet natural gas is come out.The outlet of lightweight fluid (8) and centrifugal transferpump (5) by interchanger (3) bottom collect.
