Abstract:
1. An apparatus for combining two or more streams that when mixed produce a vapor stream containing one or more components that can condense to form liquids and/or solids at temperatures above ambient, said apparatus comprising: a vessel having an outer wall; a baffle wall located within said vessel and in proximity to said outer wall to create an annular space between said baffle wall and said outer wall for receiving at least one dilution stream, a vessel interior space within said baffle wall for containing a combined stream; at least one dilution stream inlet extending through said outer wall for delivering said dilution stream into said annular space; at least one dilution stream outlet for delivering said dilution stream from said annular space to said vessel interior space; at least one injection fluid stream inlet extending through said outer wall and said baffle wall for delivering an injection stream to said vessel interior space and mixing said injection fluid stream with said dilution stream to form a combined stream in said vessel interior space; and at least one combined vapor stream outlet extending through said outer wall for delivering said combined vapor stream from said vessel; wherein said dilution stream inlet delivers a dilution stream comprising a vapor having a dew-point temperature that is less than that of said combined vapor stream and delivers said vapor to said annular space at a temperature above the dew-point temperature of said combined vapor stream.
