Fluor executed a lump-sum contract for engineering, procurement, construction, and project management on an FCC plant addition project at the Kralupy Refinery in the Czech Republic.
The FCC plant included a new integrated resid conversion complex being added to the existing Ceska Kralupy Refinery. This resid conversion complex was based on an upgraded UOP Combustor-Style FCC reactor-regenerator, able to effectively charge and convert a low-sulfur resid mix of medium heaviness. Safety studies were performed for the Kralupy and Litvinov refineries.
The core FCC reactor-regenerator is supported by a collection of carefully integrated units and systems:
- FCC main fractionator, integrated heavy FCC gasoline desulfurizer reactor train and FCC gasoline merox (two-stage extractive concept)
- FCC gas concentration plant
- Dedicated amine system (using DEA amine) - dedicated sour water stripper system
- High purity propylene plant (single MD tray tower and heat pump) - Olefinic C3 and C4 LPG Merox (extractive type)
- HHP steam for export and letdown to HP steam system for "self-powering” of key blowers/compressors
- Upstream vacuum distillation unit to provide flexibility in controlling qualities of the resid cat feed composite
- DCS control system
The capacity of the FCC unit was 3,800 tonnes per day, and the capacity of the vacuum unit, 2,000 tonnes per day.
