Abstract: A hydrotreatment unit for an oxygenate feedstock is provided, the unit including: a hydrotreatment reactor; a first cooling unit; a high-pressure separator and a low pressure flash unit. The hydrotreatment unit is arranged to feed at least a part of the hydrogen-rich stream from the high-pressure separator to the hydrotreatment reactor; and the hydrotreatment unit is arranged to feed a part of the degassed hydrocarbon-rich stream from said low pressure flash unit as a hydrocarbon recycle stream to the hydrotreatment reactor. Also, a method for hydrotreating an oxygenate feedstock using the hydrotreatment unit.
