This unit accepts reduced crude processed by the CDUs and distills them into the primary products including LPG, naphtha, kerosene, light gas oil and refined crude 700 F typical 100 psig

10 Sentry Equipment Corp Sampling Solutions Specialty Heat Exchangers VBC – Visbreaking Unit VBC or Visbreaker is a thermal cracking unit. This unit accepts vacuum tower resid or the very viscous vacuum tower bottoms and uses high heat (800 F) to crack the hydrocarbons into fuel oil, naphtha and light gas oil 800 F typical 100 psig Typically a patented process (UOP, shell)

11 Sentry Equipment Corp Sampling Solutions Specialty Heat Exchangers HTU – Hydrotreater Unit HTU or Hydrotreater uses a recycled hydrogen stream and catalyst to convert sulfur compounds to hydrogen sulfide, nitrogen to ammonia and aromatic hydrocarbons to stronger hydrocarbons. This unit accepts vacuum tower light and heavy gas oil and converts them to gasoline, kerosene and naphtha 200 F typical 200 PSIG liquids 1300 PSIG gases

12 Sentry Equipment Corp Sampling Solutions Specialty Heat Exchangers CRU – Catalytic Unit CRU or catalytic reforming unit removes oxygen, nitrogen and sulfur from naphtha that contaminates the units catalyst and then converts it to gasoline Up to 500 F typical 200 PSIG liquids Typically a patented process (Unifiner, etc.)

13 Sentry Equipment Corp Sampling Solutions Specialty Heat Exchangers SRU – Sulfur Recovery Unit SRU or sulfur recovery unit converts hydrogen sulfide into elemental sulfur Up to 200 F typical 100 PSIG liquids

14 Sentry Equipment Corp Sampling Solutions Specialty Heat Exchangers FCCU – Fluid Catalytic Cracking Unit Fluid catalytic cracker (FCC) uses high temperature and catalyst to crack heavy gas oil mostly into gasoline.
