                                                             the steam conditions will be 5kg/cm2G and 159°C.
           4.6.1  Plant Scope
                                                                 Steam generation unit will consist with one Furnace
              STRP will process about 24,000 tons/yr of waste solvent   to burning spent solvent and natural gas, discharging flue
           and generate about 91,200 tons/yr of low-pressure steam for   gas and recovery the heat into steam by boiler. Four liquid
           ZWM plants. The Table 7 demonstrates the four types of waste   waste solvent streams shall be fired. Spent solvent shall be
           solvent feed.                                     sprayed into the furnace by the sprayer lance and make
