Fluid Catalytic Cracker (FCC) Units for Sale

Used 9,000 TPD ISAL (Heavy FCC Gasoline Desulphurization) Unit built in 2005. The ISAL process is a two-reactor, selective hydrotreating process for treating a wide range of naphtha feedstocks. The process uses a bifunctional catalyst system to desulfurize FCC gasoline and to achieve a controlled transformation of the gasoline hydrocarbons. When treating FCC gasoline, the ISAL process reduces the sulfur content to very low levels, saturates almost all of the olefins and restore the octanes through the specific hydro conversion reactions (hydrocracking, isomerization, de alkylation). ISAL catalyst is specially formulated for the selective hydrocracking of the low octane cuts in gasoline to allow in the end regaining the octanes. This is the major advantage of ISAL process vs. a conventional FCC naphtha hydrotreater, where considerable octane loss occurs with olefin saturation. The operating conditions and process equipment used in the ISAL process are similar to those used in a conventional naphtha hydrotreater. Thus, no special operating procedures are required.

Used 68,000 BPD Fluid Catalytic Cracker (FCC) Unit built in 1982. This unit comes complete with the cracker reactor, catalyst regenerator, and distillation column.

Used 23,000 BPD Fluid Catalytic Cracking Unit (FCCU) built in 1950. The purpose of the Fluidized Catalytic Cracking Unit is to crack and convert a lower value Atmospheric Gas Oil (AGO) and Vacuum Gas Oil (VGO) stream from the Crude Unit, into higher value gasoline blend components. This is accomplished by use of slide valves to control circulating catalyst level and temperature between the Reactor and Regenerator.

Used 15,800 BPD Fluid Catalytic Cracker (FCC) Unit built in 1983. The FCCU was originally designed for 1800 MT/D but later processed up to a nominal 2300 MT/D of fresh feed comprising heavy VGO. The fresh feed can change from HS VGO to LS VGO depending on the source of crude to the refinery. Most of the fresh feed comes to the FCCU hot from the vacuum distillation unit. The remainder of the feed comes cold from tankage. The unit was operated to maximize the production of light distillate. The light distillate is taken as a side draw from the main fractionator called “LLCO” which comprises the heavy end of the gasoline and the light end of the light cycle oil, 160°C - 300°C in ASTM D86 distillation. This LLCO is then hydrotreated for blending in the 10 ppm sulfur automotive diesel pool. In 2010, the FCCU carried out a revamp project. The primary goals of this revamp project were to (i) increase the fresh feed rate to 2400 MT/D using the HS VGO feed, (ii) improve the reactor yield slate to maximize the production of LLCO and minimize the production of dry gas and slurry and (iii) reduce the production of butadiene in the C4’s by approximately 50%.
