JOURNAL FREE ACCESSThe natural gas industry is developing at a rapid pace in such countries as the United States, European countries and Soviet Union. Main reasons for the increase of consumption of natural gas are the increase of reserves, realization of ocean transportation of LNG and demand for non-pollutant energy sourcess because of aunti-pollution consideration.
In Japan also, there have been obvious signs for an increased demand for natural gas as a result of the fast growth of needs for and import of petroleum products, These potential requirements for natural gas may be met to some extent by the future development of the exploration efforts in Japan, but for the most part they must necessarily be dependent upon the import of LNGView full abstractDownload PDF (2668K) -

JOURNAL FREE ACCESSLNG (Liquified Natural Gas) is a novel fuel recently attracting public attention as a key to solve the recent environmental pollution problem. The paper deals with the LNG recieving terminal facilities, now under construction, at the Semboku Works of the Osaka Gas Company, as well as with the circumstances leading to the importation of LNG, preequisites of equipment design work, basic designing conditions, circumstances of studies made on the selection of equipments and general description of these equipments. The paper also discusses about the prospect of the future role to be played by the developing LNG industry as a whole.View full abstractDownload PDF (1819K) -

JOURNAL FREE ACCESSThe plan for the production of liquid oxygen and nitrogen, utilizing the cold of LNG which was imported by Tokyo Gas into her Negishi Works, brought about the establishment of a new company named Tokyo Liquid Oxygen Co. of which Kanto Tar Prod. is one of the parent companies.
This is the first project of the world for utilizing LNG Cold in the commercial scale.
The author describes the specific feature of this particular project and outlines the present and future aspects of technology as a whole in relation to the cold utilization of LNG, covering the evaluation of coldness, the balance of the cold quantity and the scale of utilizing industry and the economic analysis of some probable application.View full abstractDownload PDF (824K) -

JOURNAL FREE ACCESSDepending on its mode of use, LNG possesses great value as a source of cold energy. The application of the cold energy of LNG to the petrochemical industry is explained hereunder.
Facilities actually constructed and in operation which utilize the cold energy of LNG to separate the heavy components contained in the LNG are those at the Barcelona Terminal in Spain and the La Spezia Terminal in Italy.
A method of using the cold energy of LNG for separation purposes and for the ethylene production unit itself, wherely ethane separated from LNG containing heavy components in used as feed for ethylene production, is described in the literature released by Air Products Ltd. in “LNG-1”.
There is a process, in the patent stage, by which heavy components are separated from LNG containing such comporents and high-pressure methane gas is produced. This method does not require the use of the compressor for which a patent application has been lodged by Air Liquid.
The methane is liquefied using the cold energy of LNG and vaporized after being pressurized with a pump.
Similarly, Conch Methane Service has announced its patented method which utilizes the cold energy of LNG to separate refinery tail-gas into its individual components.
A scrubbing method using LNG and propane chilled by means of liquefied nitrogen to remove trace quantities of impurities from hydrogen, is adopted.
The use of the cold energy of LNG in an ethylene production plant, taking the case of an ethylene production rate of 300, 000 tons per year, is described briefly.
In this case, 1, 380, 000 tons per year of LNG will be required if all necessary refrigeration is to be carried out by the sole use of LNG.
Trial calculations were per formed on the basis of using LNG for the ethylene refrigeration around the demethanizer only. These calculations evaluate the cost of one kilogram of LNG at 1.59 yen.
The use of the cold energy of LNG, especially in ethylene production units, will probably be realized with the establishment of stable supply and increased imports of LNG.View full abstractDownload PDF (1538K) -

JOURNAL FREE ACCESSThe conductornetric meter for SO2 in atmosphere generally shows a rather higher value comared with the conventional West-Gaeke method. It was confirmed that the higher values in this conductometric method were caused not by solving the NOx, HCl and other electrolytes, but by the loss of sensitive cell solution during gas sampling. Correction procedures of observed values were also shown.View full abstractDownload PDF (917K) -
