Abstract

PURPOSE:To eliminate the need of installing compression engine related equipment for high compression by heating LNG increased in pressure by a pump by atmospheric heat or waste heat, and evaporating LNG to produce high-pressure gas. CONSTITUTION:LNG increased in pressure to a designated pressure by a LNG pressure-up pump 4 is transferred in an adiabatic pipe 7 to be injected in a caburetor 8. The evaporation and expansion of LNG injected in the LNG carburetor 8 are promoted by heating of external heat. A designated amount of high pressure gas increased to a designated pressure by expansion is fed by pressure into a high pressure gas tank 17 having a pressure gauge 22 from a gas distributor 14 through a flow meter 15 and a valve 16.

地域ｎ国において使用されており、増加の傾向がある。Normally natural gas! Compressed natural gas (hereinafter referred to as dlt G) compressed to about 30 to 20 J atmosphere is held in a pressure tank, and automobiles and other engines that are driven using it as fuel are pollution-free, safe, and gasoline, LPG, etc. Because it is more economical than other fuels, it is used in countries in other regions, including Europe and America, and is on the rise.

（）の利用検討が各方面で行われている。In Japan, for the above reasons, 0N is used as an alternative fuel such as gasoline and IIPG for automobiles and other engines, or as an alternative to city gas by pipe rice supply.
The use of () is being considered in various fields.

合、約４００倍に成るので、天然ガスの大容量の輸送形
態としては液体状態で行われるのが通常である。However, in Japan, where natural gas resources are scarce compared to other countries, natural gas (liquefied natural gas), NG, is introduced in a liquid state at approximately 1 atm, -/AJC, by LNG tankers, and is commonly used. It is heated to room temperature with seawater, etc., and is widely used as natural gas, mainly as a fuel for thermal power generation, and as a raw material for city gas. As a physical property of natural gas, when changing from a liquid state to a gas state, its volume increases approximately 400 times, so natural gas is normally transported in a liquid state in large quantities.

して輸送、貯蔵する以外に、ＯＮＧとしての輸送。However, in order to maintain natural gas in a liquid state, it is necessary to maintain it at an extremely low temperature of -1.2C under atmospheric pressure. Therefore, in order to transport LNG, tankers or storage tanks need to be made of materials that can withstand this extremely low temperature, and aluminum, stainless steel, Ni steel, etc. are usually used.6 On the other hand, as mentioned at the beginning, In addition to liquefying, transporting and storing natural gas, we also transport it as ONG.

もその一環として積極的に行われている。Strength is required. Therefore, ONG is not suitable for large-capacity transportation and storage, but it can be used as fuel for automobiles and other engines as mentioned above, or as gas for small and medium-sized housing complexes where it is difficult to construct pipelines for supplying i-Gas. Promising applications for ONG include gas supply and temporary gas supply during disasters. The future plan for the introduction of LNG in Japan is JA, tθ, 10,000 tons/year in 1932, and in recent years, consideration has been given to expanding the use of natural gas other than for electricity or city gas. The development of applications for aHa is also being actively pursued as part of this effort.

充填するものである。しかしガス体の圧縮であるため、
圧縮機の所要動力は可成り大きく、その動力費は充填天
然ガス価格のＩＯ％程度をしめているのが実情である。The current method for producing ONG is to compress natural gas to about /10 to -00 atmospheres using a compressor, and then fill it into a pressure container. However, since it is a compression of a gas body,
The power required for the compressor is quite large, and the actual situation is that the power cost is about IO% of the price of filled natural gas.

〔発明の目的〕[Purpose of the invention]

本発明は、このような実情に鑑みなされたもので、簡単

的方法を提供せんとするものである。The present invention has been made in view of these circumstances, and provides a simple yet rational means, specifically, eliminating a large amount of compressor power for compression during ONG production, which is seen in the conventional OHG production method. Therefore, LN() is used directly as an OHG raw material. That is, a predetermined amount of I+NG is pressurized to a predetermined pressure by a pressurizing means such as a pump, this pressurized LNG is injected into a pressure-resistant container, and the LNG is vaporized and expanded by heating to obtain ONG having an arbitrary internal pressure. The aim is to provide an economical way to do so.

m critical temperature - g:L! Since it is rC, it is in a gaseous state in a temperature range of -5C or higher, regardless of the pressure. In other words, in order to vaporize LNG, it is necessary to heat it in such a low temperature range, so direct heating with water, seawater, etc. risks clogging the pipes due to freezing of the water, seawater, etc., so this is not recommended. The heating within the IING vaporizer in the system shall use an intermediate medium such as propane.

Further, the intermediate medium circulation pipe (II) has a heat transfer section (toα)t (tob), and one heat transfer section (to
α) is placed in the LNG vaporizer (8), and the other heat transfer part (tab) is placed in the ventilation duct αυ. The heat transfer part (tab) in the ventilation duct αυ is forcibly heated by air or another heating source,
The heat heats the LNG in the LliG vaporizer (8), causing it to vaporize and expand. The heating source of the heat transfer part (TOB) located inside the ventilation duct αυ uses an atmospheric heat source of air, but it is better to use exhaust gas heat from a gas turbine, gas engine, etc. or factory waste heat. Effective.

The vaporizer (8) is connected via a pipe (IS) to a gas distributor α having a pressure gauge αB.The high pressure gas ('OMG), which has reached a predetermined pressure, is transferred from the gas distributor α to a flow rate. A predetermined amount of OWa is pumped into an ONG tank aη having a pressure gauge (2) via a pressure gauge (Li2.pulp←Q).

としてより経済性のあるＯＮＧの製造が可能となる。The present invention does not produce 0N() using a high-stage, high-compression type compressor, which is done in the conventional method, but simply injects LNG pressurized by a pressure-boosting means such as a pump into a closed container, and Alternatively, heat the LN using waste heat, etc.
The present invention not only eliminates the need for compressor-related equipment that was required in the prior art for high compression of natural gas. The large amount of power required for compression can also be reduced, making it possible to produce ONG more economically as an alternative fuel.

以上のように本発明は、従来方法の不利な点を充分補い
つる画期的なものである。As described above, the present invention is an epoch-making method that fully compensates for the disadvantages of conventional methods.
