To help improve air quality, governmental agencies around the world have legislated new standards for lower sulfur content in gasoline and diesel. Many refiners are producing cleaner fuels by using hydrodesulfurization (or hydrotreating), a process that removes sulfur from feedstock by passing it over a fixed bed of catalyst in the presence of large amounts of hydrogen. Using its expertise in modular design and fabrication, CB&I built this 35,000 barrel per day hydrotreater at Valero Energy Corporation’s Ohio refinery. The unit removes contaminants from gasoline grade feedstock to produce low sulfur gasoline. |
