…showed last 75 words of 533 total…vapor. A 26-meter heat exchanger is rather long and given a lack of space in the plant, this may not be possible. An alternative to this would be to add an additional heat exchanger for cooling the ammonia vapor, so two shorter exchangers will replace the longer one. Besides the given length of the ammonia heat exchanger, we are confident that the above system gives the most efficient heat transfer with minimal cost and material.
