FIELD: chemical technology.
SUBSTANCE: invention relates to a device for reducing the pressure drop in a hydrocracking system containing a set of throttling washers. In this case, the washers have a variable flow area, ensured by the fact that the inlet hole of the washer has a larger diameter than the outlet hole. Moreover, the axis of the outlet hole of the washer is shifted relative to the axis of its inlet hole.
EFFECT: improved reliability of the hydrocracking system due to reduced risk of erosive wear and destruction of system components in the separation section.
