Abstract
A system for ammonia distillation may include a condenser to condense ammonia vapor into liquid anhydrous ammonia, a flush tank to receive a flushed portion of the liquid anhydrous ammonia, a collection tank to receive a collected portion of the liquid anhydrous ammonia, and a corrosion inhibitor dispenser to transfer a corrosion inhibitor to the collected portion of the liquid anhydrous ammonia to form corrosion-inhibiting liquid anhydrous ammonia.
Claims20
A system for ammonia distillation comprising:
- a source of liquid ammonia configured to enable distillation of liquid ammonia to form an ammonia vapor;
- a condenser fluidly directly coupled to the source of liquid ammonia and configured to condense the ammonia vapor into liquid anhydrous ammonia;
- a flush tank fluidly directly coupled to the condenser and configured to receive a flushed portion of said liquid anhydrous ammonia from the condenser;
- a collection tank fluidly directly coupled to the condenser and configured to receive a collected portion of said liquid anhydrous ammonia from the condenser;
- and
- a corrosion inhibitor dispenser fluidly connected to the collection tank and configured to supply a corrosion inhibitor to said collected portion of said liquid anhydrous ammonia to yield corrosion-inhibiting liquid anhydrous ammonia,
- wherein said collected portion of said liquid anhydrous ammonia has a purity, and wherein said purity of said collected portion of said liquid anhydrous ammonia is at least approximately ten times greater than a purity of said liquid ammonia.

A system for ammonia distillation comprising:
- a liquid ammonia source configured to enable distillation of liquid ammonia and form an ammonia vapor;
- an interconnected plurality of stages, each stage of the interconnected plurality of stages comprising:
- a condenser to condense the ammonia vapor into liquid anhydrous ammonia;
- a flush tank to receive a flushed portion of said liquid anhydrous ammonia from the condenser, the flush tank fluidly directly coupled to the condenser;
- and
- a collection tank to receive a collected portion of said liquid anhydrous ammonia;
- the system further comprising:
- of the interconnected plurality of stages, at least one stage having a corrosion inhibitor dispenser supplying a corrosion inhibitor, the corrosion inhibitor added to said collected portion of said liquid anhydrous ammonia to form corrosion-inhibiting liquid anhydrous ammonia,
- wherein said collected portion of said liquid anhydrous ammonia has a purity, and wherein said purity of said collected portion of said liquid anhydrous ammonia is at least approximately ten times greater than a purity of said liquid ammonia.
