FIELD: gas industry.
SUBSTANCE: invention relates to method for flushing gas of hydrotreated outlet flow from hydrotreatment zone. According to suggested method first part of flushing water flow is added to hydrotreated outlet flow to form combined flow and combined flow is condensed. Then combined flow is directed into separator, which comprises substantially cylindrical body connected in turn with settler and tower. Second part of flushing water flow is supplied into tower for flushing of ammonia and hydrogen sulphide, running inside tower. Method allows to achieve higher level of ammonia removal from recirculation gas and to avoid corrosion of downstream equipment.
EFFECT: invention also relates to separator, which is used in disclosed method.
