AM-07-62 Solving Clean Fuels Production and Residuum Conversion through Hydroprocessing Integration

Description:

The increase in crude oil prices, particularly in lgt/hvy diff has renewed interest to convert VR to lgter products.However,strict req for clean fuels created a diff tech and econ hurdle for conversion projects.CLG improved efficiency of hydroprocessing tech to meet challenges.Process schemes upgrading resid to mid-distill will be presented that incorporate dev in ART hydro cats.Improvements in LC-Fining with use of integrated hydroprocess allows LC-FINING to directly produce clean fuels from a high conversion VR operation in single hydroprocess complex.Advances employ SmART Cat Sys. customized to individual ref objectives.As ref gear for ultra low sulfur diesel,many discover constraints such as hydro avail forces them to sacrifice cat performance.Application allows ref to balance demands for hydrogen with need to achieve clean fuels.Integrated process also accepts additional dist streams needing additional upgrading. This allows a new LC-FINING based project to meet important ref upgrade needs in economic manner.Lower gas sulfur req cause refiners to look to FCC pretreater.This can mean using higher activity Co/Mo desulfur cat which results in decreased nitro removal and decreased PNA sat.While this helps reduce FCC gas sulfur,has neg impact on FCC conversion and gas yield.Application of ApART Sys offers opportunity to lower FCC gas sulfur and improve FCC upgrade.These dev increase choices to achieve clean fuels with opt resource utiliz applying latest cat advances with best tech.
