CHAPTER 5c - OUTLINE HYDROCRACKING I. Hydrocracking is a versatile catalytic refining process that upgrades petroleum feedstocks by adding hydrogen, removing impurities, and cracking to a desired boiling range. Hydrocracking is an alternative to solvent refining technology which allows production of a far more pure and stable base stock. The feed, which is typically a blend of HCGO and VGO and in certain cases includes residue hydrocracker VGO, is sent to the first stage of the hydrocracker and is severely hydrotreated.

Hydrocracking is a flexible catalytic refining process that can upgrade a large variety of petroleum fractions. Distillate Hydrotreating In general, all liquid distillate streams contain sulfur compounds that must be removed Saturate olefins in diesel to improve the cetanenumber Hydrogenation at the high pressure produces small amounts of naphtha from hydrocracking Required to get at the embedded sulfur. It is carried out mostly for producing middle distillates and fuel oils from vacuum distillates, catalytic dewaxing for lube base stock at a pressure below 10 MPa and at a temperature range varying from 350°C to 450°C. Hydrocracking. Hydrogenation removes impurities in the feed such as sulphur, nitrogen and metals. The various equipment like reactors are. Namun proses Hydrocracking tetap tidak kehilangan pamor dan tetap diminati karena keunggulannya yang dapat mengubah minyak berat (gas oil) menjadi distillate (maksimasi kerosene dan diesel). To answer to the world demand on middle distillates, the hydrocracking process has been developed not only at a processual level, but also on the catalysis domain. A hydrocracking unit, or hydrocracker, takes gas oil, which is heavier and has a higher boiling range than distillate fuel oil, and cracks the heavy molecules into distillate and gasoline in the presence of hydrogen and a catalyst.

A process is disclosed for the preparation of a light hydrocarbon oil distillate by (1) hydrocracking a vacuum distillate, (2) separating the product of (1) into distillates and a residue, (3) catalytic cracking the residue obtained in (2) and a portion of the vacuum distillate to thereby isolate a light hydrocarbon oil distillate. The main objective of this work was to create a kinetic model of refinery vacuum residue hydrocracking and to monitor the impact of the operating conditions on the product yields. This process has at least two stages. [1] for hydrocracking of vacuum residue at 380, 400 and 420oC were used in a simple kinetic model using a series of CSTRs to calculate the residue conversion and the VGO, distillate, naphtha and gaseous products concentrations and molar flow rates. The combination of desulfurized, denitrogenated lighter products of lower overall aromaticity makes hydrocracking an ideal process for producing diesel, jet and gas turbine fuels meeting the more stringent fuel specifications effective starting in 2005. Naphtha/Distillate Hydrocracker Feed thousands of barrels/year 3. The most recent grassroots hydrocrackers were designed to maximise the production of middle distillates from increasingly difficult feedstocks such as FCC light cycle oil (LCO), heavy vacuum gas oils (HVGO) and heavy coker gas oils (HCGO). on the other hand, the yield of the middle distillate while hydrocracking is reduced and the cracking products have a tendency to discoloration, when the reaction temperature exceeds 370°C. •Industry-leading hydrocracking technology for optimizing the production of high quality fuels •Multiple solutions for next cycle and long term opportunities strategies: - Hydrocracking innovations - Bottom of the barrel upgrading - Alliances - Honeywell process solutions •Flexible offerings to meet refiners’ processing and financial.
