ABSTRACT:
A method for recovering NH3present 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.
