Technology
for revamping amine sweetening process
The
increase of organic sulfur compounds in sulfur and amine
wastewater increases the difficulty for amine sweetening.
Current amine sweetening system mostly combines amine
crystallizing and sulfur removing, but is not efficient in
removing all organic sulfur compounds from the by-product
ammonia, resulting poor quality for the ammonia.
To
address this problem, FRIPP carried out optimization and
revamp for the tri-stage condensation system and the amine
crystallizer, and is developing efficient desulfurizer
that has high organic sulfur removing activity. At the
same time, an analysis method has been developed for
determining the contents of hydrogen sulfide and organic
sulfur in ammonia.
