T04 The 242-A Evaporator began waste management operations in March of 1977. The 242-A Evaporator is Located in the
200 East Area and is used to treat mixed waste from the Double-Shell Tank (DST) System by removing water and east volatile
organics. Two waste streams Leave the 242-A Evaporator following the treat*ant process. The first waste stream, the
concentrated slurry (approximately 40 to 60 percent of the water is removed during evaporation along with a portion of the
volatile organics), is pumped back into the DST System. The second waste stream, process condensate (containing a portion of
the volatile organics removed from the mixed waste during the evaporation process), is routed through conde ns ate filters
before release to a retention basin (Liquid Effluent Retention Facility). Offgasses iron the process are routed through a
de-entrairment unit, a prefilter, and high-efficiency particulate air filters before being discharged to the environment.
The 242-A Evaporator is used to treat up to 870,642 Liters (230,000 gallons) of mixed waste per day.
4102Tank C-100, a 4.3-meter (14-foot) diameter and 5.9-meter (19-foot) high tank with a maximum design capacity of
67,380 liters (17,800 gallons ), is Located in the condenser room. Process condensate fr om the primary, inter-, and
after-condensers drain by gravity to tank C-100, which is constructed of stainless steel. in addition, tank C-100 receives
potentially contaminated drainage from the vessel vent system via a 102-liter (27- 9allon) seal pot.
Tank C-A-1 is located inthe evaporator room and consists of two sections: the lower (Liquid) section, a 4.3-meter (14-foot)
diameter stainless steel shell, and the upper (vapor) section, a 3.5-meter (11.6-foot) diameter stainless steel shell,
containing two wire-mesh de-entrairmmt pads for the removal of liquids and solids that could be carried into the vapor
header. Process slur ry from the reboiler discharges to the evapbrator vessel (tank C-A-1). Concentrated process slurry
exits the Lower section of tank C-A-1 via the 28-inch' recirculation line. Vapor flows out of tank C-A-1 through a
42-inch vapor Line at the top. The um
maximum
capacity of tank C-A-1 is 103,217 liters (27,267 gallons),

A. DANGEROUS WASTE NUMBER - Enter the fear dig it number f ro m Chapter 173.303 WAD for each listed dange rous waste you will handle. R you handle
dange ro us wastes which m not lis ted in Chapter 173-303 WAD, enter the tour dig it number(,) that dssmribas the cha racteristics and/or the to xic con-
Lmmants of those mng. rom wastes.
