| Abstract;150t/d Bituminous coal liquefaction pilot plant (PP), supported by New Energy and Industrial Technology Development Organization (NEDO), has been operated for the period 1967,3-1998,9. For verifying of the materials selected in design of PP, the materials of equipment and pipes were investigated following 6200 hours of operation of PP, as a part of an overall coal liquefaction project. The following features in coal liquefaction process were noticeable under the severe operation conditions. . High temperature, high pressure and hydrogen service . Corrosive compounds in coal . High concentration of ash and slurry In this report, the nondestructive inspection such as penetration test, magnetic test etc. and the fracture tests such as impact test, tensile test etc. were carried out, for the main equipment and pipes in the liquefaction unit of PP. The adequacy of the selecting materials in PP was confirmed through this inspection study. The selected materials are basically clarified. The most proper material selections, by the evaluation of the materials based on the results of this inspection study are expected, for the design of commercial plants. (author abst.) |
