Abstract
The invention is a method of introducing an aggressive liquid additive into a vapor-containing process stream including (a) heating the liquid additive by a heating means thereby producing a heated additive; (b) passing the heated additive to an injection quill in fluid communication with the vapor-containing process stream; and (c) passing the heated additive from the injection quill into the vapor-containing process stream.
Claims18
A method of introducing an aggressive liquid additive into a vapor-containing process stream comprising
- (a) heating said aggressive liquid additive by a heating means thereby producing a heated aggressive liquid additive;
- (b) passing said heated aggressive liquid additive to an injection quill in fluid communication with said vapor-containing process stream;
- and
- (c) passing said heated aggressive liquid additive from said injection quill into said vapor-containing process stream.
A method of introducing an aggressive liquid additive into a vapor-containing process stream comprising
- (a) passing said aggressive liquid additive to a heat exchanger, wherein said aggressive liquid additive is heated a sufficient amount to vaporize at least a portion of said aggressive liquid additive;
- thereby producing a mixture consisting essentially of said aggressive liquid additive and a vaporized form of said aggressive liquid additive;
- (b) recovering said mixture from said heat exchanger;
- (c) passing said mixture to an injection quill in fluid communication with said vapor-containing process stream;
- and
- (d) passing said mixture from said injection quill into said vapor-containing process stream.
A method of introducing an aggressive liquid additive into a vapor-containing process stream comprising
- (a) collecting said aggressive liquid additive in a container having a jacket;
- and passing a hot fluid through said jacket, thereby producing a heated aggressive liquid additive, and wherein at least a portion of said heated aggressive liquid additive vaporizes, thereby forming a vaporized form of said aggressive liquid additive;
- (b) recovering said vaporized form of said aggressive liquid additive;
- (c) passing said vaporized form of said aggressive liquid additive to an injection quill in fluid communication with said vapor-containing process stream;
- and
- (d) passing said vaporized form of said aggressive liquid additive from said injection quill into said vapor-containing process stream.
