The invention relates to methods and devices for compressing gas and can be used in oil and gas and other industries for compressing gas containing vapors of Melaleuca (heavy) components, including associated gas, with receiving compressed gas and condensation of heavy components.
The known method of gas compression [Sokolov E. Y., singer N. M. Jet devices. - 3-e Izd., Rev. - M.: Energoatomizdat, 1989, p. 8] by compression in the jet compressor working environment, which is used as a gas or liquid, and subsequent separation of compressit with receiving compressed gas, condensate or waste working medium in admixture with the condensate. The method is carried out using a device consisting of a jet compressor, equipped with lines of input gas and the working medium and which is connected to the line supplying the mixture of compressit and working environment with a separator equipped with a line output of compressed gas and condensate or condensate mixture with the spent working medium).
The main disadvantage of the known method and device is the large power consumption due to the low efficiency of jet devices. In addition, the resulting compressed gas is contaminated components of the work environment and the condensate is unstable and has a high saturated vapor pressure.
Most Blimber�key technical essence to the claimed invention, a method and apparatus for compressing gas [Tronin A. P., Pugach, I. A. Technology for separation of hydrocarbon gases, Moscow: khimiya, 1976, p. 31], which consists of compressor, equipped with a gas inlet line and the line output compressit, a refrigerator equipped with a line input/output external refrigerant, connected to a supply line chilled compressit with a separator equipped with a line output of compressed gas and condensate. The gas compressed by the compressor with getting compressit, which is cooled by an external coolant (e.g. water or air) and separated with receiving compressed gas and condensate. When gas compression, forming the stratified condensate, separated with obtaining light and heavy condensates, and the separator is additionally equipped with a line output light condensate. When compression of associated gas, if necessary, from a compressed gas by throttling can be derived fuel gas for gas engines.
The disadvantages of this method and device are:
- the relatively high temperature of the compressed gas, which hinders its further processing, for example, by adsorption, low temperature separation, etc.,
- high saturated vapor pressure of the condensate for dilution of gas components, which complicates its further use�s,
- loss of heavy components (e.g., hydrocarbons C5+when compression of associated gas),
- high temperature the dew point of water and hydrocarbons in the fuel gas produced by the throttling of the compressed associated gas, which complicates the operation of the gas engines.
The object of the invention is to reduce the temperature of compressed gas, the reduction of the saturated vapour pressure of the condensate, reducing the loss of heavy components, and receipt of associated petroleum gas of the fuel gas with reduced dew point temperature of water and hydrocarbons.
When implementing the invention, the technical result is achieved:
- increase the volumetric output of compressed gas, reducing the loss of heavy components with compressed gas and reduction of the saturated vapour pressure of the condensate by cooling compressit in the dephlegmator,
- lowering the temperature of the compressed gas, and receipt of associated petroleum gas of the fuel gas with reduced dew point temperature of water and hydrocarbons due to the additional cooling compressit in the dephlegmator fuel gas.
Said technical result is achieved in that in the known method, including compressed gas with a compressor, cooling compressit external refrigerant and its separation from �rucenim compressed gas and condensate the peculiarity lies in the fact that the cooling of compressit carried out in the dephlegmator, and compressed after cooling, external refrigerant subjected to further counterflow cooling throttled circulating a part of the compressed gas, the compressed gas is separated into carrying and circulating parts, last drosselbart and serves as the refrigerant in the reflux condenser, and the condensate get stabilized condensate.
Stable condensate can be optionally cooled to a temperature transportation or processing.
When compressed gas that forms during cooling of the stratified condensate, the latter is advisable to separate.
The proposed method is carried out using a device consisting of a compressor equipped with a gas inlet line and the supply line compressit, a refrigerator equipped with a line input/output external refrigerant, and a separator equipped with a line output of compressed gas, a feature of which is that as a room separator and installed the baffle, the bottom of which is equipped with line output, stabilized condensate, while at the top of the reflux condenser is placed the heat and mass transfer unit, the top of which is connected by a line feed then�tidal gas equipped with a throttle device with a line output of compressed gas, and the bottom is equipped with a line output fuel gas, and in the middle of the baffle above the line supplying compressit posted of heat and mass transfer unit, equipped with line input/output external refrigerant.
For cooling the stabilized condensate in the line of withdrawal of the latter can be additionally installed the refrigerator.
To output light of condensate in compressed gas that forms during cooling of the condensate, exfoliating into light and heavy condensates, the bottom of the dephlegmator is advisable to equip the line of output light condensate, and the line of withdrawal of the condensate serves as the line of withdrawal of heavy condensate.
In the proposed method, the cooling compressit carried out in the reflux condenser, equipped with heat and mass units, it allows you to condense heavy components of the gas with the formation of phlegm, and also to carry out fractionation of the latter, thereby to reduce the loss of heavy components with compressed gas, to increase the volumetric yield of the latter and to reduce the saturated vapor pressure of the condensate.
Additional counterflow cooling compressit fuel gas is cooled by throttling due to the Joule-Thompson to a temperature lower than the temperature in�asnago refrigerant, can further reduce the temperature of compressed gas and to obtain a fuel gas with reduced dew point temperature of water and hydrocarbons.
The equipment of the device instead of the fridge separator and a reflux condenser, equipped with two heat and mass units, the cooled fuel gas and an external refrigerant, allows the proposed method and achieve the claimed technical result due to the use of a secondary energy source - heat compressit that in the known methods is lost.

The proposed method is performed as follows (Fig.). Gas (I) is compressed by the compressor 2, compressed (II) was cooled under the conditions of delegatie first external refrigerant (III) of heat and mass transfer in block 3 of the reflux condenser 4, then fuel gas (IV) in heat and mass transfer unit 5, from the top of the reflux condenser 4 is withdrawn compressed gas (V), which is separated into the carrying part (VI), which is withdrawn from the plant, and the circulating part (VII), which drosselbart through the device 6 (conventionally shown a throttle valve), the resulting cooled fuel gas (VIII) cool compressed of heat and mass transfer in the upper unit 5 and output from the installation. From the bottom of the dephlegmator derive a stable structure with three wheels�vanny condensate (IX).
The invention is illustrated by the following example.

When gas compression in accordance with the prior art under similar conditions obtained 1,63 t/h of hydrocarbon condensate from the saturated vapor pressure by Reid 1688 kPa and 4259 nm3/h of compressed gas with a temperature 40,1°C, throttling of which received 2000 nm3/hour of fuel gas with methane index of 45.9, the dew point temperature on the water -11,7°C hydrocarbons of 1.6°C. the Loss of hydrocarbons C5+compressed gas amounted 0,572 t/h.
From this example it follows that pre�proposed method and device allows to reduce the temperature of compressed gas, to reduce the saturated vapor pressure of the condensate to reduce the loss of heavy components, and to obtain a fuel gas with a low dew point temperature of water and hydrocarbons. The invention can be used in oil and gas and other industries.
