Abstract
A chemical adding apparatus for crude oil dehydration demulsify comprising a liquid storage tank, a safety valve, a chemical adding pump, a proportion pump and a liquid level gauge is characterized in that the liquid storage tank is a cylindrical high pressure vessel provided with the safety valve on the top and welded with a pipe at the upper surface equipped with the chemical adding pump and a pipe at the bottom surface equipped with the proportion pump. The sidewall and the bottom of the liquid storage tank are provided with the liquid level gauge and a draining duct equipped with a draining valve respectively. As a result, the chemical adding apparatus for crude oil dehydration demulsify can well add the demulsify during crude oil dehydration and avoids some disadvantages such as high labor intensity cost by artificially formulated demulsify fluid and influence on crude oil dehydration and crude oil production decline due to nonuniform mixing of demulsify and water and is suitable for adding the demulsify during crude oil dehydration in oilfield pipelines.
Description
Technical field
The utility model relates to a kind of device that adds chemical agent in the oil pipeline line; Particularly a kind of device that adds dehydration of crude oil demulsifier; Be that a kind of employing is advanced Teat pipette and added medicament, and with the medicine adding device of dosing pump discharge opeing.
Background technique
In crude oil chemical dehydration process, need to add dehydration demulsifying agent, especially need to add dehydration demulsifying agent in the individual well gathering line and reduce Oil Well Back Pressure and help crude oil demulsification.At present, adding dehydration demulsifying agent generally all is to adopt manual method to finish.Earlier demulsifier is diluted to the aqueous solution according to a certain percentage in container, again the demulsifier aqueous solution is added in the crude oil.Labor intensity is very big in the dosing process; In addition, because the medicine dilution, demulsifier mixes uneven with water, and the demulsifier aqueous solution mixes inhomogeneous with the crude oil that needs dehydration, have a strong impact on dehydration of crude oil rate, influences crude oil production.
The model utility content
The purpose of this utility model is: a kind of dehydration of crude oil demulsifier medicine adding device is provided, and this device can be finished the adding of crude oil pipeline dehydration demulsifying agent, and demulsifier and crude oil mixes, and improves dehydration of crude oil efficient.Overcome at present artificial dosing and mix inequality, the big deficiency of the labor intensity of dosing work.
The technological scheme that the utility model is taked is: dehydration of crude oil demulsifier medicine adding device by liquid container, safety valve, advance Teat pipette, dosing pump and level meter and form, feature is: liquid container is cylindrical high-pressure bottle jar, and the top is equipped with safety valve.Be welded with pipe on liquid storage tank skin top, install one on the pipe and advance Teat pipette.Be welded with pipe in liquid storage tank skin bottom, a dosing pump is installed on the pipe.On the liquid storage tank skin, level meter is installed.Be welded with drain pipe in liquid storage tank skin bottom, blowdown valve is installed on the drain pipe.
For satisfying dehydration of crude oil dosing technological requirement, the volume of liquid container is between 200～500 liters, between withstand voltage 2.0MPa～3.5MPa.
For satisfying construction requirement, the discharge capacity of advancing Teat pipette is 1m
3/ h～6m
3/ h, lift 2m～6m.The ratio pump delivery is 0.5ml/h～30ml/h, outlet pressure 1.5MPa～3.0MPa.
For understanding the liquid container internal pressure at any time, pressure gauge can be installed at liquid storage tank skin top.
The use operating process of summary dehydration of crude oil demulsifier medicine adding device helps to understand the utility model.When adding crude oil demulsifier in crude oil pipeline, at first demulsifier is added in the cylinder type medicine storing pot by advancing Teat pipette, demulsifier arrives certain liquid level in liquid container; According to the oil flow size in the oil transport pipeline, pacify needed demulsifier flow then, the passing ratio pump joins demulsifier in the crude oil.Because the dosing pump continuous dosing is in the crude oil that flows, demulsifier and crude oil mix in flow process automatically; The pressure ratio of dosing pump is higher in addition, and demulsifier is added in the crude oil in the mode of spraying, and it is more even that demulsifier is mixed with crude oil.
The utility model beneficial effect: utilize the utility model dehydration of crude oil demulsifier medicine adding device can realize the dosing of dehydration of crude oil process well, overcome that manually to join demulsifier solution labor intensity big, demulsifier mixes uneven with water, influence the dehydration of crude oil, influences the deficiency of crude oil production.Be adapted at adding demulsifier in the crude oil conveyance conduit.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
