Abstract
The utility model discloses a well-mouth natural gas deep dehydration device provided with a laval supersonic separator. The well-mouth natural gas deep dehydration device comprises a well-mouth natural gas pipeline ball valve, a natural gas cooler, a tubular heat exchanger, a cylindrical filter and a laval supersonic separator which are connected din series by a pipeline, wherein in the tubular heat exchanger, natural gas at an outlet of the natural gas cooler passes through the inside of a stainless steel shell tube; dehydrated natural gas at an outlet of the laval supersonic separator passes through the outside of the stainless steel shell tube and is connected with a downstream pipe network through a dehydrated natural gas outlet; and sewage discharging ports are respectively formed in the bottom of the cylindrical filter and the bottom of the laval supersonic separator and are connected with a centralized sewage discharging port through a thread ball valve a and a thread ball valve b. The well-mouth natural gas deep dehydration device disclosed by the utility model has the advantages of cleanness, environment friendliness, energy source economization, increase of dehydration speed on the premise of saving the construction cost and the operation cost, small size, low cost and high reliability.
Description
(1) technical field
The utility model relates to the well head natual gas dehydrate unit, particularly a kind of well head advanced dewatering equipment for natural gas that is provided with Lavalle supersonic speed separator.
(2) background technology
Contain a large amount of saturated steams in the Sweet natural gas, easily condense into liquid water in the transport process process, liquid water easily forms gas hydrate with hydrocarbon, thereby causes pipeline, valve and instrument obstruction.Existing gas dehydration technology comprises sieve technology, triglycol dehydration and membrane separation technique.Investment and the running cost of these dehydration techniques are all higher at present.
(3) utility model content
The purpose of this utility model is the problem for above-mentioned existence, and a kind of well head advanced dewatering equipment for natural gas that is provided with Lavalle supersonic speed separator is provided, and this dewatering unit volume is little, cost is low, reliability is high.
The technical solution of the utility model:
A kind of well head advanced dewatering equipment for natural gas that is provided with Lavalle supersonic speed separator is consisted of and is connected in series by pipeline by well head natural gas line ball valve, Sweet natural gas water cooler, tubular heat exchange, core strainer and Lavalle supersonic speed separator; In tubular heat exchange, the Sweet natural gas of Sweet natural gas cooler outlet is by in the stainless steel tubulation, and the dehydration Sweet natural gas of Lavalle supersonic speed separator outlet is by being connected with the downstream pipe network outside the stainless steel tubulation and via the dehydration gas outlet; Core strainer is respectively equipped with sewage draining exit with the bottom of Lavalle supersonic speed separator and is connected with concentrated sewage draining exit with screw thread ball valve b by screw thread ball valve a.
Working routine of the present utility model:
The higher well head Sweet natural gas (moisture) of humidity is behind the entrance ball valve, by the precooling of Sweet natural gas water cooler, reduce the dew point of Sweet natural gas, can under equal conditions improve the dehydration degree of depth, moisture after the precooling carries out reducing temperature twice with the dry and cold Sweet natural gas that has generated again in tubular heat exchange, moisture after the cooling filters solid particulate and drop through core strainer again, then enter Lavalle supersonic speed separator and carry out gas-liquid separation, the dry gas of separating is heated the rear downstream dry gas pipe network that flows into as the cold fluid of tubular heat exchange by the moisture of tube side.
The scope of application of the present utility model is: the well head advanced dewatering equipment for natural gas.
Advantage of the present utility model: this well head natual gas dehydrate unit has the two-fold advantage of clean environment firendly and save energy, has improved the dehydration degree of depth under the prerequisite of saving construction and running cost; This device volume is little, cost is low, reliability is high.
