Low Cost Alternative Fuel (MSAR · SFO™)

Your Problem:

You want an alternative fuel that costs less than conventional fuel oil or natural gas and can be used in your existing equipment or you don't have access to natural gas.

Our Solution:

Quadrise Canada has an alternative fuel product, Multiphase Superfine Atomized Residue Synthetic Fuel Oil (MSAR® SFO™) that can cost between 5 to 50% less than your current fuel oil, bunker oil or natural gas and hence reduces your operating costs. The degree of cost reduction is contingent upon feedstock cost, availability and client capability. MSAR® SFO™ can be used in existing or slightly modified boilers, fired heaters, or engines.

Who We Help (Our Customers):

If you are in the Power, Marine, Thermal Heavy Oil (SAGD), Refining, Upgrading, Petrochemical, Metallurgical, Pulp and Paper, Mining, Oilsands, and Cement Industries and using oil, heavy fuel oil, diesel or natural gas to fuel your diesel engines, boilers, turbines, or fired heaters to create steam, power, or heat, then we have a solution for you.

Multiphase Superfine Atomized Residue Synthetic Fuel Oil (MSAR® SFO™)

MSAR® SFO™ is a proprietary emulsion fuel manufactured and supplied by Quadrise Canada under exclusive license from Akzo Nobel. Although there are various "instantaneous" water in hydrocarbon based emulsion fuels on the market provided by various vendors that can provide diesel engine efficiency improvements for light feedstocks such as diesel or bunker fuel, MSAR® SFO™ is the only hydrocarbon in water based emulsion fuel that has long term stability, can be stored and pumped at room temperature, can improve efficiencies, reduce NOx and particulate matter emissions and can reduce energy economics by using very very heavy residual feedstocks.

How is it made?

MSAR® SFO™ is made by combining a liquid hydrocarbon with water and proprietary additives in a custom designed processing unit with manufacturing sizes between 30 to 4,000 barrels per day in a single train. The product is a highly stable fuel emulsion consisting of between 70 to 80 percent hydrocarbon in water. Quadrise Canada can manufacture MSAR® SFO™ from virtually any liquid hydrocarbon.

MSAR® SFO™ can be manufactured from heavy oil or any low value liquid residue generated in upgrading and refining processes such as vacuum tower, visbreaker, or solvent deasphalter bottoms. The fuel cost is related to the value of the residual feedstock available for manufacturing.

Where is it used?

MSAR® SFO™ can fuel many industrial facilities in the cement, lime, glass, metal smelting, pulp and paper, spent sulphuric acid regeneration, fertilizer, petrochemical and petroleum refining industries. It can be used for direct firing, steam and on-site power generation applications rather than using high cost natural gas, fuel oil, or purchasing power from the grid. Many industrial facilities are outfitted to capture the sulphur dioxide containing flue gases from the combustion of sulphur containing hydrocarbon residues used to manufacture MSAR® SFO™.

Why does MSAR® SFO™ burn better than straight fuel and generate lower particulate emission?

The best steam atomized heavy fuel drops are around 80 microns in diameter. Combustion occurs at the fuel drop surface, and the fuel must burn completely in the boiler or piston combustion zone to minimize particulate emissions. Heavier residues do not burn as readily as lighter fuels, and the drop interior tends to char before it can combust. Unburned char is sticky, and adheres to the inside walls of the chamber or boiler tubes, creating severe fouling (lower efficiencies) and corrosion.

In contrast, MSAR® SFO™ can be air atomized into 80 micron drops, that contain thousands of small 5 micron fuel droplets and has 17 times more surface area than a standard steam atomized drop. This property provides a much larger surface for contacting the combustion air with the fuel, leading to the need for low excess oxygen, quicker and more complete combustion, and less char formation (lower particulate emissions). In addition, since the fuel contains liquid water, the combustion temperature is lower, leading to lower NOx formation.

Where has hydrocarbon in water Emulsion Fuel MSAR® SFO™ been used?

Emulsion fuel technology was developed by British Petroleum (BP) in the mid 1980's. Under a joint venture between BP and PDVSA (Petroleos de Venezuela SA) the "first generation" fuel emulsion was produced from 9 API Orinoco belt crude. Orimulsion® grew to a sizable market of over 120,000 barrels per day, but was abandoned in 2006 by PDVSA for political reasons. In the mid 90's, MSAR® was invented by Quadrise Limited (ex BP researchers) using Akzo Nobel technology and additives to convert refinery generated hydrocarbon residues in the minus 2 to plus 8 API range to a finely tuned fuel emulsion for various applications. In 2008, Quadrise Canada innovated MSAR® SFO™ to a "third generation" whereby very heavy asphaltenes in the minus 10 to minus 2 API range, sometimes referred to as 'liquid coke', can be converted to MSAR® SFO™.

MSAR® SFO™ has been test burned in Wartsila diesel engines, in test furnaces at the Canadian National Research Council CANMET facility, in several power plant boilers in the UK, Italy, Sweden, in commercial boilers at the Alstom test burn facility in Connecticut, USA, in rocket engines designed for power production, at a Thermal heavy oil SAGD bitumen production project in northern Alberta, and in a 120,000 barrel test at a Lithuanian power station.

Key Features and Benefits of MSAR® SFO™ are:

Can emulsify very heavy low cost residues
  • fuel manufacturing cost savings for producers and reduced costs for consumers of marine bunker fuel, #6 fuel oil, residual fuel oils, or natural gas
water content lowers combustion temperature
  • lower NOx than other fuels
  • lower V2O₅ production
  • resultant combustion zone heat flux is usually within design allowance for boiler radiant and convection sections, avoiding any boiler derating
water content increases flue gas mass:
  • increases power output (efficiency) of mass flow devices such as gas turbines
has reduced viscosity at room temperature due to the continuous water phase
  • operator ease
  • can be safely and easily pumped, stored and transported at room temperature
  • air atomization vs steam atomization (lowers parasitic steam/water demand)
  • fuel is handled below its flash point
has a very short combustion time
  • efficient burns
  • lower excess oxygen needs
  • over 99 percent carbon burnout,
  • low particulate emissions
  • minimizes boiler tube and piston fouling' leading to higher efficiency and lower maintenance
  • low carbon metallic ash suitable for metals recycling (less hazardous waste disposal)
Manufacturing sizes between 30 - 4,000 barrels/day feedstock
  • Scalability and can be conveniently manufactured on-site
Fuel droplet sizes and water content can be tailor-made
  • fuel is customized to suit the feedstock, application, handling conditions or shelf-life for a once-through-steam generator used in the oil sands industry, for a utility power boiler, or for a diesel engine
Fuel can be combusted in turbines, diesel engines and boilers
  • High efficiency co-generation applications can be considered
