FLEXICOKING™

FLEXICOKING™ is a commercially proven, continuous fluid-bed technology that thermally converts heavy oils--such as vacuum resid, atmospheric resid, oil sands bitumen, heavy whole crudes, deasphalter bottoms and FCC bottoms--to lighter, more valuable products. FLEXICOKING technology, as an integrated process, offers comparatively greater flexibility when upgrading residuum, as it provides clean liquid products as well as fuel gas or a natural-gas substitute. Essentially, FLEXICOKING eliminates petroleum coke production while providing an economical and clean fuel.

The following advantages can be expected:
• No catalyst operating costs, loss of conversion over time on-oil, cost of H2 consumption or concern of using exotic metallurgy which are associated with resid hyprocessing technologies
• A continuous fluid-bed thermal conversion process with integrated coke gasification, producing a clean fuel gas or natural-gas substitute versus a batch operation
• Process heat provided by low-value coke versus use of fuel gas fired furnaces
• A clean FLEXICOKING gas which burns well in easily modified burners in a variety of furnaces, heaters and boilers within the refinery, or can be sold to nearby plants for use as fuel; Use of FLEXICOKING gas (FLEXIGAS) for power generation is more attractive than the Delayed Coking and separate coke gasification route
• A process which flexibly accommodates a variety of feed types, particularly those with high metal content, sulfur and/or Conradson Carbon Residue (CCR)
• A process which facilitates the upgrading of very heavy feeds, e.g. bitumen from the Canadian Oil Sands at the resource site or at the refinery, wherever the FLEXICOKING gas can best be utilized as a clean, low-cost fuel gas
• Much reduced concerns about operating safety issues around the quality of the coke produced
• Significantly lower SOx, NOx and particulate emissions for refinery fuel demand when utilizing FLEXIGAS
• A large single-train capacity provides an economy of scale that reduces the investment cost per unit of throughput; up to 65 KB/SD of 20 plus wt% Conradson Carbon vacuum resid can be processed within a single unit
• High reliability with service factors routinely exceeding 90%

BenzOUT - a cost effective gasoline benzene reduction technology

The BenzOUT process is a commercially proven technology for benzene reduction in gasoline. BenzOUT converts benzene typically in a light reformate stream to higher alkylaromatic blending components by reacting a benzene rich stream with light oIefins, such as refinery grade propylene stream.

Methanol to Gasoline (MTG)

High crude oil prices have helped to spur worldwide interest in finding and developing additional sources of transportation fuels. One such consideration is the conversion of carbon containing solids (coal, petroleum coke and biomass) and natural gas into high quality, clean-burning transportation fuel.
