Abstract A compact muffler, scrubber or chemical reactor device for utilization with a combustion engine to aid in the removal of impurities from exhaust gases comprises a housing in which serially connected shallow reactant and demister compartments are horizontally arranged. An inlet line is provided which opens into the reactant compartment. The reactant compartment contains a body of reactant material and packing. The inlet line to the reactant compartment contains a venturi and an aspirator line for aspirating the reactant material into the venturi. These are so located in the upstream end of the compartment as to provide a pressure gradient which is utilized to return the reactant material to the bottom of the reactant compartment through selected orifices which also serve as surge suppressors in the muffler device.

The muffler device of claim 3 wherein said active absorbent salt is a eutectic composition molten above 395*C and consisting essentially of, in mole percent, 45 + or - 5 lithium carbonate, 30 + or - 5 sodium carbonate, and 25 + or - 5 potassium carbonate.
Claim 6
Dependent Claim
39 words
The muffler device of claim 1 wherein said reactant compartment includes a de-entrainment passageway located in the forward end of said compartment for removing a portion of entrained molten material from the exhaust gas following exhaust gas-molten material contact.
Claim 7
Dependent Claim
16 words
The muffler device of claim 1 further including surge suppressor means disposed in said molten pool.
Claim 8
Dependent Claim
19 words
The muffler device of claim 6 wherein said surge suppressor means includes a baffle containing a plurality of orifices.
Claim 9
Dependent Claim
85 words
The muffler device of claim 1 further including a first exhaust gas treatment compartment positioned downstream from said demister compartment, said first treatment compartment including separate catalyst means for receiving and treating the dry exhaust gas from said demister compartment, and still further including a second exhaust gas treatment compartment positioned downstream from said first treatment compartment and including separate catalyst means for receiving and oxidatively treating the dry exhaust gas from said first treatment compartment prior to emitting said gas from the muffler device.
