Definitions
- the barrier member is in the form of an inflatable bag connected to the fluid inlet of the pressure vessel.
- An inflatable water bag has never before been used inside a pressure vessel to prevent direct contact between water and the subjected gas to be compressed.
- the inflatable water bag may be dimensioned to occupy the internal space of the pressure vessel when inflated, in order to pressurise the gas while keeping the switchable air vent on the inlet water pipe open to atmosphere.
- the internal shape and volume of the pressure vessel may be substantially identical to the external shape and volume of the inflatable water bag.
- the bag may be made of any flexible or composite materials such as reinforced rubber, fibre reinforced plastic etc.
- the gas inlet of the first pressure vessel and the gas inlet of the further pressure vessel may be connected to the same source of gas.
- the compressor may comprise at least one further pressure vessel having a gas inlet connected to the gas outlet of the first pressure vessel and a fluid inlet for the high pressure fluid.
- the compressor may be arranged to introduce the high pressure fluid into the further pressure vessel via the fluid inlet whereby to compress further a volume of gas in the further pressure vessel. In this way, the desired pressure of the gas can be achieved in stages.
- the gas inlet of the (or each) pressure vessel is supplied with gas from a water electrolyser.
- the gas is hydrogen.
- the gas compressor may be connected to a source of gas to be compressed or may be directly connected to an electrolyser to compress hydrogen and oxygen gas.
- the gas compressor may comprise one or more of a bottom water tank, a high pressure water pump, at least one an inflatable water bag installed inside a pressure vessel, a gas inlet valve to the pressure vessel, a high pressure gas outlet purge valve from the pressure vessel, a nitrogen gas purging valve, switchable atmospheric air vents located on top of the bottom water tank, a piping configuration and valve mechanism, monitoring and control devices for pressure, temperature, flow rate and fluid level, non return valves installed after the high pressure gas-purge valve and after the outlet of the water pump, inline gas sensors, a liquid condensing and separation unit, an oxygen removal unit for removing oxygen from hydrogen gas, a gas drying unit and an electronic control system.
- a liquid vapour condensing unit, a liquid separation unit, an oxygen removal unit, a gas drier and a liquid absorption unit may be fitted after the gas outlet purge valve of the pressure vessel.
- a gas sensor may detect the purity of gas and send an electrical voltage and/or current signal to the electronic control box.
- the compressed gas may be vented to the atmosphere if the purity of the gas is not at a desired level or for any maintenance work.
- the invention also provides a gas compressor directly coupled with an atmospheric electro lyser, wherein the de-oxo-drier removes the traces of oxygen gas present in hydrogen gas followed by gas drying.
- the operating range of the compressor is from 10 mbar gauge pressure up to very high pressure such as 700 bar in multiple stages depending on the output pressure of the water pump and the volume of the pressure vessel.
- the flow rate of the gas compressor is in the range of 10 cubic centimetres per minute to several hundreds normal cubic metres per hour.
- the higher gas pressure inside the pressure vessel will deflate the water bags; the gas compressor operates the multiple valves as per the above sequence to empty the water from the pressure vessel or from the inflatable water bag by pumping water back into the bottom water tank.
- the gas is fed into the empty pressure vessel followed by pumping of water into the inflatable water bag or directly into the pressure vessel.
- Figure 1 is a schematic diagram of various components of this invention
- Table 1 provides an example of the compression ratio but following the same principle different compression ratios will be achieved by changing the physical parameters of this invention
- Table 2 describes the sequence of valve control corresponding to Figure 1 ; there will be several ways to perform the operation using the same physical configuration and/or different configurations using the same components.
- Figure 2 shows an alternative configuration of a gas compressor according to an embodiment of the invention
- Table 3 describes the sequence of valve control corresponding to Figure 2.
- the inflatable water bag (10) is made of flexible materials such as reinforced rubber, composites, fibre reinforced plastic bags etc.
- the safe operating pressure of the inflatable water bag is about 10-15 bar and the design pressure is 25bar.
- the differential pressure between the inside and outside pressure of the fully inflated water bag never exceeds 15 bar because the water bag is supported when fully inflated by the wall of the pressure vessel; the physical volume change from the deflated to the inflated water bag is up to 20 times or even more; therefore the gas can be compressed up to 20 times by the fully inflated water bag resulting in 20 times increase in gas pressure inside the first pressure vessel (4).
- the first pressure vessel (4) is securely connected to a leak free port (32) of a second pressure vessel (33) via an adjoining pipe (14) and a fourth valve (14).
- the gas outlet port is connected to a high pressure gas delivery pipe (39) a seventh valve (40), and a non return valve (41).
- Figure 2 shows an alternative configuration of an embodiment of a gas compressor according to the invention, which combines four functionalities of gas compression, gas drying, gas cooling and gas cleaning at low cost and greater efficiency.
- a fifth valve 111 between the first vessel 101 and a low pressure electro lyser stack 103 is open, while a sixth valve 112 between the second vessel 102 and the low pressure electro lyser stack 103 is closed.
- a seventh valve 113 between the first vessel 101 and a high pressure gas delivery line 116 is closed.
- An eighth valve 114 between the second vessel 102 and the high pressure gas delivery line 116 is also closed.
- the gas in the second vessel 102 is compressed up to 700 bar or higher from ambient pressure in a single stage by gradual filling of liquid by the high pressure liquid pump 108.
- the compressed gas is then discharged by opening the eighth valve 114 into the high pressure gas delivery line 116 while keeping the third valve 106 and the sixth valve 112 closed.
- An output valve 109 is opened to deliver high pressure gas or fill up a buffer tank for storage.
- the gas inlet of the first vessel 101 is controlled by the fifth valve 111 which is connected to the electro lyser cell 103 producing hydrogen and oxygen gas or any other sources of gas.
- the electrolyser cell 103 may be as described in GB 2469265.
- Table 3 shows the position of the valves during the gas compression and gas discharge in both vessels 101, 102.
- the liquid is sprayed by nozzles 110, 115 inside the pressure vessels 101, 102 to scrub various impurities by physical absorption or by chemical reaction.
- sodium hydroxide (NaOH), potassium hydroxide (KOH) solution is used to remove C0 2 from biogas during compression.
- Hydrogen sulphide (H 2 S) is removed by scrubbing in ferric sulphate solution or by washing of the raw gas in water. Removal of tar, oil, hydrocarbon, particulate and other impurities is achieved by various scrubbing techniques with relevant liquid solution.
- the present invention primarily relates to the compression of hydrogen gas and any other gaseous substance using high pressure water pump.
- the present invention provides a safe and leak proof gas compressor due to the use of water seal making it ideal for compression of explosive gases such as hydrogen.
- This invention allows a low pressure gas such as from an atmospheric water electrolyser to increase the gas pressure significantly in a much more economical way than costly pressurised electro lysers or conventional hydrogen compressors.
