Abstract
Utilization of residual oil fractions in the light of environmental protection. The conversion of residual fractions produced in refineries into raw materials of chemical industry offers an alternative to fueling in thermal power stations, which is noteworthy from an energetic as well as environmental point of view. Processes may be compared using some criteria as yardstick, which have been derived from the request for pollution abatement. The modern process of high‐pressure gasification keeps in line with those criteria. It is considered as a source of large quantities of hydrogen and carbon monoxide. Furthermore a thermal power plant is considered, in which the flue‐gas desulphurization is replaced by fuel desulphurization operated at high pressure. A comparison of processes shows typical productions and consumptions as well as thermal efficiencies. The remaining environmental pollution is also tabulated. Thermal efficiencies of chemical processes are remarkably higher than that of the power plant process.
