Title	Incineration of Hazardous Waste in a Mobile System
Creator	Acharya, Prakash, P.E.
Publisher	Digitized by J. Willard Marriott Library, University of Utah
Date	1984
Spatial Coverage	presented at Tulsa, Oklahoma
Abstract	The principal system described is the third generation of Pyrotech's hazardous waste processors. The system can burn a wide variety of solid and liquid wastes efficiently while meeting stringent emmision standards. Two mobile liquid incinerators were constructed prior to developing the solids handling capability. The first mobile waste processor (MWP-75) obtained an EPA permit to burn 60 gallons per hour of polychlorinated biphenyls (PCBs) up to 42 percent (by. wt.) concentration, in 1982. The second unit was scaled to process 100 gal./hr. of 77 percent (by. wt.) PCBs. The unit is scheduled to under go a trial burn in October, 1984. Although the first unit is permitted to burn only PCBs at this time, other liquid wastes with heating values above 4500 BTU./lb. can also be incinerated.

OCR Text	Show 5-10-12 gases are mixed with secondary air in the afterburner. The off gasses are maintained at 2200 DEG.F in the secondary combustor and the gases are then cooled in the quench section by a water spray. HCL and free chlorine are removed in the scrubber by recirculating caustic solution and the clean off gases are then vented to the atmosphere through a 30f high stack. This unit has a sophisticated laboratory to analyze various gas and liquid samples. The control room is equipped with a computer that is capable of controlling various process parameters and acquires the necessary data. MOBILE WASTE PROCESSOR-(MWP-100) The process schematic of the MWP-100 is presented in Figure 5. This is the second generation of the mobile waste processors. The basic design of MWP-100 is the same as of MWP-75 except that it is designed for higher feed rate and PCB concentrations. The scrubber incorporated into the MWP-100 is designed to remove HCL using water instead of caustic solution. The concentrated acid solution is withdrawn from the quench box and externally neutralized using 25% caustic solution. The scrubber can remove HCL but not free chlorine. The formation of free chlorine is reduced greatly by incineration at very high temperature,(= 4200 DEG.F) and by using low excess air. Table II summarizes the actual destruction test parameters taken during the 72 hour trial burn. Actual test data of the MWP-75 comply with EPA guidelines.
