Definitions

  • the invention relates to a device for supplying a consumer with gas from a supply of cryogenic liquid gas, in particular liquid natural gas (LNG).
  • LNG liquid natural gas
  • These are primarily consumers who use fuel gas, eg. B. engines. But there are also other consumers into consideration, for. For example, those that require purge gas.
  • LNG liquid natural gas
  • consumers expect that the gas will be supplied to them with a pressure specified by the consumer and to be maintained precisely, which varies with time, depending on the working condition of the consumer, and can also undergo sudden changes.
  • the amount of time required gas ie. H. the mass flow of the gas, usually not constant, but depending on the load of the consumer.
  • Typical consumers for which the invention is contemplated are diesel engines for marine propulsion or smaller, electricity-producing power plants which are optionally gas operated in such a manner that at each stroke in the cylinder in addition to the diesel oil, the so-called pilot oil , a certain amount of gas is introduced under high pressure.
  • the gas requirements of these engines may change rapidly.
  • the required pressure depends on the respective power of the engine and is typically between 150 and 300 bar for LNG.
  • Particularly pronounced and erratic are the changes in pressure and mass flow when in a group of consumers, eg. B. in a power plant group, a consumer or engine suddenly, z. B. due to an emergency stop completely fails.
  • the device which supplies such consumers with gas must be able to meet such changes.
  • the still liquid gas is first brought to high pressure in a conventional manner and then, in the state of high pressure, for. B. by supplying heat through a heat exchanger, evaporated, d. H. converted into the gaseous state.
  • There are two regulators of which a first regulator regulates the pressure of the gas delivered to the consumer via a pressure regulating valve in the flow direction downstream of the evaporator, while a second regulator regulates the pressure of the gas upstream of the pressure regulating valve and behind the pressure increase used for high pressure pump by he adjusted the mass flow of the gas delivered by the high-pressure pump.
  • this mass flow is now influenced not only by the manipulated variable of the second regulator, but also by the manipulated variable of the first regulator acting on the pressure regulating valve behind the evaporator.
  • the setting of the mass flow of the gas is equivalent to setting the volume flow of the gas, because both quantities are proportional to the density, more precisely the volume density of the mass of the gas, at the place of adjustment as a proportionality factor.
  • Preferred means for combining the manipulated variables of the two controllers are characterized in claims 2, 3 and 4.
  • the mass flow thus preferably depends on a sum of the two From manipulated variables, possibly with a limitation of the sum corresponding to the permissible signal range of the control device for the mass flow, and optionally further with an individual influencing the manipulated variable of the first controller according to a specific, preferably dynamic transfer function, as far as the manipulated variable to the mass flow setting is shared.
  • the mass flow adjustment is realized according to claim 6 preferably via the mass flow determining speed of the high pressure pump by providing an electric motor together with an associated, commercially available speed controller for driving the high pressure pump, which uses the combination of the two manipulated variables for speed setting.
  • the extension of the device according to the invention according to claim 7 has no purpose to allow a constant "excess" operation of the device. Rather, this development takes into account the fact that conventional high-pressure pumps have a lower mass flow below which they no longer work satisfactorily. So there is a smallest mass flow of the gas that the pump can not go below.
  • the third regulator only operates by opening the second pressure control valve associated with it, thus allowing a return of liquid gas to the storage tank when the consumer requests a mass flow which is so low that it is below the minimum value the high-pressure pump is located.
  • the second and the third controller may each have their own pressure transducer, but are preferably connected to a common pressure transducer. In principle, it is not decisive whether this is arranged upstream or downstream of the evaporator in the flow direction.
  • the pressure transducer detects the pressure of the liquid gas in front of the evaporator.
  • the device according to the invention is preferably used on board ships to supply the ship propulsion with natural gas (LNG), especially when the ship's propulsion comprises so-called MEGI engines, which in the manner described above with Diesel and gas are operated.
  • LNG natural gas
  • MEGI engines which in the manner described above with Diesel and gas are operated.
  • These motors require that the LNG be provided at the input to a given pressure with high accuracy.
  • the pressure values can vary widely over a wide pressure range; typical are 150 to 300 bar.
  • the device according to the invention is able to follow exactly even fast pressure ramp curves. This is possible with the device according to the invention, although the mass flows required by the marine engine can be completely different, independent of the pressure requirement.
  • the invention is explained in more detail below with reference to a preferred exemplary embodiment.
  • the sole figure shows a process flow diagram of a device according to the invention.
  • liquid natural gas LNG
  • a high-pressure pump 3 is connected via a discharge line 2, which is driven by an electric motor 4.
  • a connecting line 5 leads from the outlet of the high pressure pump to an evaporator 6.
  • a consumer 8 here in the form of a diesel engine, which is additionally operable with high-pressure gas.
  • a damper 9 is also connected.
  • the high pressure pump 3 driven by the electric motor 4 draws cryogenic liquid gas from the storage tank 1 and sets it under high pressure.
  • the damper 9 a partially filled with liquid gas and partially filled with self-vaporized gas container, dampens the resulting pressure oscillations in the LPG.
  • the liquefied gas passes via the line 5 to the evaporator 6. This includes not shown in detail a heat exchanger by means of which the liquefied gas is heated and thereby evaporated.
  • the ver vaporized gas which is thus gaseous and thereby has the high pressure generated by the high-pressure pump 3, passes through the output line 7 to the diesel-gas engine eighth
  • a pressure control valve 10 is inserted, which is adjusted by a first controller 11.
  • the controller 11 detects the means of a pressure transducer 12 as a controlled variable Pressure of the gas in the flow direction behind the pressure control valve 10 and forms it and from an externally set value SP1, the manipulated variable for the pressure control valve 10th
  • a second controller 15 detects via a pressure transducer 16 as a control variable, the pressure of the liquid gas in the connecting line 5 and forms it and from an externally predetermined setpoint SP2 a manipulated variable which reaches the one input of an adder 17.
  • a pressure transducer 16 detects via a pressure transducer 16 as a control variable, the pressure of the liquid gas in the connecting line 5 and forms it and from an externally predetermined setpoint SP2 a manipulated variable which reaches the one input of an adder 17.
  • the manipulated variable of the first regulator 11 passes through a transfer member 13, the manipulated variable of the first regulator 11.
  • the transfer member 13 modifies this manipulated variable, as far as the adder 17 is supplied, in accordance with a realized in the transmission element, dynamic transfer function, the individual ratios of the device can be adapted.
  • a speed controller 19 for the electric motor 4 is connected via a limiter 18, a speed controller 19 for the electric motor 4.
  • the speed controller 19 is formed for example as a frequency converter, the speed of the electric motor in accordance with the limited sum of the over the frequency of the electric motor 4 supplied supply current, the sum of the two actuating variables 17 formed in the adder 17 sets both manipulated variables of the controllers 11 and 15 and thus also the funded by the high-pressure pump 3 mass flow of the liquefied gas.
  • a second pressure regulating valve 20 is connected to the connecting line 5, the output of which is connected to the storage tank 1 via a return line 22.
  • the pressure control valve 20 is actuated by the manipulated variable of a third regulator 21, which receives the control variable via the pressure transducer 16 as the controller 15, the pressure of the liquefied gas behind the high pressure pump 3 and forms therefrom and from an externally predetermined desired value SP3, the manipulated variable for the pressure control valve 20.
  • the setpoint SP2 of the second controller 15 is higher than the setpoint SP1 of the first controller 11 and the setpoint SP3 of the third controller 21 is again higher than the setpoint SP2 of the second controller 15.
  • the regulators 11 and 15 together adjust the pressure of the vaporized gas entering the diesel gas engine 8.
  • the third controller 21 provides for a reduction of the gas pressure at the outlet of the high pressure pump 3, when the lower limit speed of the high pressure pump. 3 is reached and therefore by influencing only the pump, the pressure can not be lowered further.
  • the first controller 11 is implemented as an industry-standard PI controller, set for fast parameterization, high gain factor and small integration time constant.
  • the second controller 15 is designed as an industrial PID controller with the usual additional functions and works as a P controller. The same applies to the third controller 21.
  • the maximum deviations of the pressure and mass flow of the gas from the requested set values were less than 1% stationary and less than 5% dynamic.
  • the dynamic control performance test was based on two cases, namely an increase in consumer power from 0 to 100% within two minutes, and a consumer performance decrease - simulating an emergency shutdown - from 100% to 0% within ten seconds.
