Abstract
Abstract The reaction vessel accommodates a corrosive liquid bath such as molten carbonate and a reactant such as petroleum coke and air. The vessel includes an oxidation chamber and a reduction chamber separated by a tee-shaped baffle. A liquid level control chamber cooperates with the reduction chamber and also serves as the outlet. Orifices extend through the baffle so that there is a controlled flow and recirculation of the bath through the chambers. The reactant is injected into the oxidation chamber below the level of the bath. The vessel is lined with a refractory brick or block, an insulating refractory sealant, and sections of expanded metal or metal grating.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
24 words
The vessel of claim 1 having a baffle positioned within the first chamber between the second inlet means and in the first orifice means.
Claim 2
Dependent Claim
27 words
The vessel of claim 1, said chambers defined by a refractory lining, an insulating refractory sealant, an expanded metallic binding positioned therebetween and encapsulated by said sealant.
Claim 3
Dependent Claim
185 words
A reaction vessel for treating molten carbonate containing sulfur oxides to reduce the sulfur oxides to sulfides comprising: A. an oxidizing chamber having molten carbonate inlet means at the top thereof, air and carbon compound inlet means along a side thereof exiting near the bottom thereof and gas outlet means through the top thereof; B. a reducing chamber positioned adjacent the oxidizing chamber and having gas outlet means through the top thereof; C. a tee-shaped baffle separating the oxidizing and reducing chambers, the leg of the tee extending into the reducing chamber; D. a plurality of lower orifices extending through a lower portion of one end of the baffle between said chambers; E. a plurality of upper orifices extending through an upper portion of an opposite end of the baffle between said chambers; F. a bath control and exit chamber positioned adjacent the reducing chamber, said chamber positioned above an adjustable section of block; G. a first passageway extending from the bottom of the reduction chamber through the block and into the bath control and exit chamber; and H. a second passageway exiting said chamber.
Claim 4
Dependent Claim
26 words
The reaction vessel of claim 4 including a baffle positioned within the oxidizing chamber between the air and carbon compound inlet means and the lower orifices.
Claim 5
Dependent Claim
191 words
A reaction vessel for treating a liquid with a reactant comprising: A. a first chamber; B. first inlet means for directing the liquid into the first chamber; C. second inlet means positioned near the bottom of the first chamber to introduce a reactant into the first chamber below the liquid level; D. a second chamber positioned adjacent the first chamber; E. a baffle means separating the first and second chambers; F. first orifice means extending through a lower portion of one end of the baffle connecting said chambers; G. second orifice means extending through an upper portion of an opposing end of baffle means connecting said chambers; H. outlet means exiting the second chamber means; and I. liquid level control means cooperating with the outlet means to control the level of the liquid in said chambers and comprising a third chamber separated from the second chamber by a partition formed of block, said outlet means extending from a lower portion of the second chamber means through said block into said third chamber and second outlet means exiting through said block, the liquid level being controlleD by the height of the block.
