FIELD: process engineering.
SUBSTANCE: invention relates to method of diesel fuel production. Particularly, it pertains to compression of makeup hydrogen flow in compressor to bleed hydrogen flow from said compressed makeup hydrogen flow. Hydrocarbons flow is subjected to hydro cracking in the presence of hydrogen flow and catalyst to get outlet hydro cracking products flow to be separated in liquid flow and vapour flow to be compressed to get hydrogen compressed flow. Liquid outlet flow is fractionated to obtain diesel fuel flow. Hydrogen flow is bled for hydraulic cleaning from said compressed hydrogen flow for hydraulic cleaning of diesel fuel flow in the presence of hydrogen flow and catalyst to get outlet hydro cracking products flow. Invention covers also the diesel fuel production plant.
EFFECT: perfected process.
