What are the options to meet Tier II sulfur requirements?
To meet ultra-low sulfur specifications for diesel and gasoline, U.S. refiners will 'retool' existing facilities; feedstock changes, operational/processing adjustments and installing new post treatment technologies are some possible choices
Combine power options with clean fuels projects
A build-own-operate project structure involving refinery upgrade results in increased product yield and power production
Cat naphtha sulfur management: undercut or not?
Several processing options can create a high-sulfur heavy cat naphtha that concentrates FCC sulfur into one stream
Consider improved liquid alkylation catalysts
To process 'cleaner fuels,' refiners will seek octane gains from the blending pool; alkylate refinement is a possible solution
Process ultra-low sulfur diesel
New catalyst technology efficiently works at the molecular level to remove thiopenes
