Definitions

  • the invention provides a process in which a flow of vaporized gas is drawn off at least one tank, compressed and divided into two component flows.
  • One component flow is then fed as a fuel to the propulsion unit of a ship, for example, to a combustion device such as a piston engine, marine boiler or gas turbine plant.
  • the other component flow is further compressed and passed in heat exchange relation with the continued flow of vaporized gas from the tank to heat the flow of vaporized gas prior to initial compression and to cool the gas component flow.
  • the cooled gas component flow is then reduced in pressure and fed back to the gas tank in at least partly liquified form. In this way, it is possible to use the low temperature of the full gas flow drawn off the tanks to cool the second gas component flow over the entire temperature range covered during cooling and, at least, partial liquifaction of this component flow.
  • the invention also provides an apparatus which includes means for drawing off the flow of vaporized gas from a gas tank. a first compressor to compress the full flow and a first branch line to deliver one component flow to the propulsion unit. Also. a second compressor is used to receive and compress the second component flow and a heat exchanger is used to effect the heat exchange between the full flow and the second component flow. A pressure reducing means is also connected to the heat exchanger and the tank to deliver the at least partly liquified gas back to the tank.
  • the second compressor does not need to operate at low suction temperatures but instead can operate at temperatures above C.
  • the drawing illustrates a schematic view of a ship employing an apparatus according to the invention.
  • a ship such as a liquified combustible gas tanker has a propulsion unit (not shown) and a plurality of liquified gas tanks 10, only two of which are shown for simplicity.
  • a means. such as a line 11, is connected to each tank 10 to draw off a flow of gas. for example. methane or natural gas vaporized in each at a temperature, for example, of l50C and approximately at atmospheric pressure.
  • the line II is connected to a cooling passage 12 in a heat exchanger 13 to deliver the flow of vaporized gas to the passage 12 for heating, for example. to 10C in a manner as described below.
  • a line 14 extends from the exit end of the passage 12 to a compressor 15 to deliver the heated flow for compression purposes.
  • a delivery line 16 extends from the compressor 15 through an aftercooler 17 and divides into two branch lines l8, 19.
  • One line 18 conveys one component flow of the gas after cooling in the aftercooler 17 to a combustion device (not shown) of the propulsion unit (not shown), e.g. a combustion chamber of a steam generator.
  • the line 18 is provided with a non-return valve 20 and a pressure regulating valve 21 which maintains the pressure in the line 18 at a predetermined value by means of a controller 21a.
  • the compressor 15 has a drive motor 22 whose speed is controlled by a controller 23 according to the pressure in the line 11.
  • the conditions are such that when the pressure rises in the line 11 due to the vaporization of gas in the tanks 10 the speed is increased and vice versa.
  • the branch line 19 carries a second gas component flow into a second compressor 24 formed by a threestage piston machine driven by a diagrammatically indicated electric motor 25. Coolers 26 are also provided between the various stages and where the gas component flow leaves the last stage.
  • a line 27 connects the outflow of the compressor 24 to the heat exchanger 13 so that the component flow of compressed gas comes into heat exchange relation with the continued flow of vaporized gas from the tanks 10 and is cooled.
  • a pressure reducing means including a line 28 and a pressure reducing valve 29 e.g. an expansion valve is connected to the heat exchanger 13 to receive the cooled component flow.
  • the pressure reducing valve 29 is operated by a controller 30 so as to maintain the desired pressure in the line 28.
  • the valve 29 communicates via a line 31 with a separator 33 which has a conventional level regulating means 34 for operating a valve 35 in an exit line 36 to a pump 46.
  • the pump 46 serves to feed the liquified gas back to the tanks 10.
  • the separator 33 is connected by a line 41 to another cooling passage 42 in the heat exchanger 13 so that volatile gas constituents, particularly nitrogen, can be drawn off along the line 41 and used to cool the gas component flow passing through the heat exchanger during liquification. These constituents then flow along a line 43 into the line 18, where they are added to the component intended for combustion.
  • volatile gas constituents particularly nitrogen
  • the aftercooler 17 is connected by a line 38 to a source of coolant, for example, cooling water for cooling the gas flow through the line 16.
  • a regulating valve 380 is disposed in the line 38 and is operated via a controller 39 in accordance with temperature variations in the compressed gas in the line 16 so that a rise in temperature is followed by increased cool ing and vice versa.
  • the process of treating and utilizing the vaporized gas resides in drawing off the gas from the tanks via the line 11 into the heat exchanger 13. After heating, for example, to 10C, the gas flows along the line 14 into the compressor 15 and is compressed to a pressure of approximately 2 atmospheres absolute and heated to about 60C. After cooling to about 40C in the aftercooler 17, one component flow of gas is conveyed via the line 18 at the same pressure to the furnace (not shown) of a steam generator which produces steam for the turbines which propel the ship.
  • the other gas component flow passes via the line 19 into the compressor 24 and is compressed, for example, to about 42 atmospheres absolute and at a temperature of, for example, 40C.
  • the gas then flows along the line 27 into the zone of the heat exchanger containing the cooling passage 12 and is cooled, for example, to 120C.
  • the gas so cooled is discharged from the heat exchanger 13 along the line 28 to the pressure reducing valve 29, where the pressure is reduced to 2 atmospheres absolute, that is, to the delivery pressure of the first compressor 15.
  • the gas now at least partly liquified, flows along the line 31 into the separator 33 and collects in the lower part of the separator 33.
  • the re-liquified portion of the gas is then re turned to the tanks 10 via the line 36 by means of the pump 46.
  • the gas component flow intended for combustion instead of going to a boiler furnace, can be fed to a diesel engine at a pressure of, for example, eight atmospheres absolute or to a gas turbine plant used to propel the ship.
  • the pressure reducing valve 29 is used to reduce the pressure to that in the tanks 10 directly, omitting the separation of volatile gases.
  • the invention provides an apparatus which is of simple construction and which uses equipment on which no complicated demands need be made.
  • a process of treating and utilizing vaporized gas from a liquified gas tank of a ship for transporting liquified combustible gas comprising the steps of drawing off a flow of vaporized gas from at least one gas tank;

  • An apparatus for treating and utilizing vaporized gas from a liquified gas tank of a ship for transporting liquified combustible gas comprising at least one gas tank;
  • a first compressor connected to said for drawing off means for compressing the flow of vaporized gas
