Abstract:
1. A process for separating off particles from a cracked gas produced in a plant for generating hydrocarbons by cracking a hydrocarbonaceous feed, said process comprising: introducing said cracked gas into a scrubbing water column, said srubbing water column comprising a column shell and a bottom, and wherein, at a region adjacent the bottom of the scrubbing water column, the shape of the column shell changes from cylindrical to conical removing a water phase from a bottom region of said scrubbing water column via a take-off at a point above the bottom of said scrubbing water column, whereby said water phase is taken off from said scrubbing water column at a height between half or the whole nominal width of said take-off above said region where the shape of the column shell changes from cylindrical to conical, and whereby said water phase removed from said bottom region of said scrubbing water column is passed into a first gravity separator.
