SEGREGATION OF STREAMS FOR THE PRODUCTION OF AMMONIA

摘要

A method for recovering NH3 present in a sour water stream containing
odiferous
compounds such as pyridines, indoles, ketones and mercaptans produced during
an
upgrading process for upgrading bitumen from oil sands into synthetic crude
comprising
treating the sour water stream in a sour water treatment unit to produce a NH3-
rich
stream and a H2S-rich stream; and hydrotreating the NH3-rich stream in a
hydrotreater
in the presence of hydrogen to remove the odiferous compounds such as
pyridines,
indoles, ketones and mercaptans and produce a treated NH3-rich stream.
