    LNG (Liquefied Natural Gas) has recently been footlighted in Japan as a nen non-pollution fuel. Since 1969 Tokyo Gas Company has been importing 960, 000 tons of LNG per annum from Alaska for city gas production and electric power generation. Another project is contemplated to import about 4, 000, 000 tons of LNG per annum from Brunei. These schemes have brought on LNG age to Japan. However there are several problems which interrupt LNG from becoming a main source of energy firstly, the higher price compared to those of competitive fuels, which could be solved by importing large quantity to acquire scale merit and also utilizing coldness and latent heat, and secondly, necessity of wide use of LNG and its technical development. The author focosses his discussion on these points.

  • LNG Industry of Overseas Transport Type
    In Case of LNG from Libya to Spain and Italy

    The LNG technology and project scale differ from each other depending on the type of LNG industry. The Libya to Spain and Italy LNG project belongs to overseas transport type, not to peakshaving type. The associated gas from the Zelten and Raguba oil field is transported by the main gas pipeline to Marsa el Brega. Startup and testing of the Brega LNG facilities and the LNG tankers have been concluded successfully. This paper also gives a general outline of LNG terminal at Barcelona and La Spezia.

    Notwithstanding the very few experience we have in construction and operations of LNG carriers throughout the world, recently, there is a remarkable tendency to rapidly increase the ship's size only from a view point to improve the; economical feasibility in transportation cost.
    The writer is afraid that this concept will not satisfy the expectation for a scale merit but rather lead to concentration of risks, whereas the LNG tank has a fatal restriction in unit tank volume due to technical problems, both in the case of the self-supporting type or the membrane type, and this boundary is quite different from the case of conventional oil tankers.

    For last several years bitumen consumptions in Japan was rapidly increased owing to several five years road programmes, and now their consumptions will be nearly four million tons in 1971.
    However there are several problems of supply, quality and application technique as follows;
    a) Air polution of high sulphur C Fuel oil-decrease processing volume of high sulphur crude oil for short term (not good for bitumen production).
    b) Improved quality binder in order to meet more severe conditions of heavy traffic volume, heavy axile load and innumerable traffic accidents.
    c) Development of New application of bitumen in order to consume surplus bitumen come from enormous capacity of in-direct desulfurizing facilities in long term.
    d) Improvement of existing application technique for road, hydraulic and industrial applications in order to secure present bitumen consumptions.
    This paper will point out these problems of bitumen market at present and future as possible.
