Description

(54) INSTALLATION FOR SECONDARY LIQUIDATION OF GAS

rum 14 maintaining constant pressure in pipe 11. The rotational speed of the drive motor 15 of the auxiliary compressor 6 is changed by the regulator 16 directly proportional to the pressure change in the pipe 2, i.e. the change in the amount of liquefied gas evaporated in tanks 1.

Another part of the compressed gas after the cooler 7 enters the main compressor 17 inlet, made in the form of a three-stage reciprocating machine with a drive motor 18 and intermediate coolers 19. Next, through the line 20, the compressed gas is directed to the heat exchanger 4, where it washes the coil 3 and Then, through the expansion valve 22, the pipeline 21 is led to the separator 23, after which the liquefied gas is again pumped out by the pump 24 to the tanks 1, and the gaseous phase is through the pipeline 25, an additional cooling coil 26 of the heat exchanger 4 p pipelines 27 and 11 goes to the power plant of the ship for burning as fuel. In this case, the regulator 28 maintains the desired pressure in the pipe 21, and the separator 23 is equipped with a level regulator 29 acting on the valve 30.

A ship power plant that uses evaporated liquefied gas as a fuel, depending on the pressure of the latter, generated by an additional compressor 6, may contain a steam boiler, a diesel engine or a gas turbine plant.

The installation works as follows.

The gas evaporated in tanks 1 with a temperature of the order of 150 ° C and at approximately atmospheric pressure enters the coil 3 of the heat exchanger 4, where it is heated, for example, to 10 ° C, and further to an additional compressor 6 due to heat exchange with a counter flow of liquefiable gas. Compressed gas with a temperature of about 60 ° C and a pressure of about 1 kg / cm enters cooler 7, after which with a temperature of about 40 ° C it is divided into two streams, one of which is led through pipeline 11 to combustion in the propulsion system of the vessel, and the other, compressed by compressor 17 to the pressure and in the order of 41 kg / cm and with a temperature (after intercoolers 19) of the order of 40 ° C, it is cooled in the heat exchanger 4 to a temperature of the order of –120 ° C due to the return of teil to the primary stream of gas evaporated in tanks 1. Next, the flow of squeezed gas expands in valve 22 to a pressure of 1 kg / cm, i.e., to the supply pressure of an additional compressor 6, and is partially liquefied, after which the boiling components, especially nitrogen-containing gas, are separated from it then heated in the additional coil 26 of the heat exchanger 4 due to the heat of the stream of liquefied gas and removed for combustion in the power plant of the vessel. The liquid phase of the liquefied gas stream with a temperature slightly lower than -150 ° C is withdrawn by the pump 24 into the tanks 1. The liquefied gas stream can expand in the valve 22 directly to the pressure in the tanks 1, 5 and this can prevent the separation of low-boiling gas components.

The gas secondary liquefaction facility allows for gas transportation to reduce evaporative gas losses and heat removed during gas secondary liquefaction to heat the vaporizing gas before it is compressed to a pressure that allows the gas to be used in the power installation of the vessel as fuel. gas is carried out over the entire temperature range of cooling and partial liquefaction of this stream. In addition, heating in the heat exchanger and compression (and, therefore, additional heating) of the total gas flow with an additional compressor ensures that the unit’s compressors operate at temperatures generally above 0 ° C, which allows the installation to be made from simpler and cheaper elements.
