Abstract
The operation of a 1t/d PSU (process support unit) was studied in the NEDOL coal liquefaction process. Modification was made, which involved the installation of a high-temperature/high-pressure sampling device for observing reaction and fluidity in the liquefaction reactor, a differential pressure measuring device, and a neutron attenuation-aided measuring device. Relative to coal injection, a 49.5-day and 49.3-day slurry injections were carried out using Tanito Harum coal, when impacts on the product yield and the operability of the unit were examined. A verification test was conducted for an improved hydrogenation catalyst, and liquefaction reactor characteristics were investigated. During a 19-day operation for the study of maintenance, newly installed equipment and devices were verified for function, and operating methods were probed into. In the survey of environments, characteristics were examined of the wastewater discharged from the Tanito Harum coal liquefaction process, and wastewater treatment methods were studied. The air, odor, and tar mist were examined with the PSU in operation, and the measured values were found to be below the management limits showing that its operation did not pose any problems relating to working environments.
