Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
32 words
A process as set forth in claim 1 wherein the step of injecting under pressure further includes the step of producing first and second spaced vortices in proximity to said shearing space.
Claim 2
Dependent Claim
28 words
A process as set forth in claim 2 wherein said step of removing said sulfur constituents comprises the step of volatilizing said sulfur constituents by an ionic reaction.
Claim 3
Dependent Claim
25 words
A process as set forth in claim 3 wherein an additional step is provided of separating said char and fuel particulates from volatilized sulfur constituents.
Claim 4
Dependent Claim
30 words
A process as set forth in claim 4 wherein additional steps are provided for applying said volatilized sulfur constituents to a variable pressure condenser to condense said volatilized sulfur constituents.
Claim 5
Dependent Claim
19 words
A process as set forth in claim 2 wherein said shearing space is energized by counter flowing vortex streams.
