PentoMuls - Water-in-Oil Technology for HFO Boilers
From Fuel Oil Fired Power Plants
PentoMuls water-in-oil emulsion technology allows online production of a stable water-in-oil emulsion to increase combustion efficiency and reduce emissions. Firing emulsions in boilers has been researched intensively for many decades. Pentol successfully commercialized this technology in 1997. PentoMuls® mechanically and chemically stabilizes fuel oil to emulsify it with water.
Action Principle
Typically, 60-80% of the ash emitted in a power plant consists of unburned carbon. We like to call this wasted energy. PentoMuls makes it possible to increase carbon consumption by up to 90%. This results in a minimum of 50% less total ash being forced through superheaters, economizers and the air heater. This ash creates deposits that clog the heat exchanging surfaces. PentoMuls fuel oil treatment provides many advantages, from cleaning the fuel oil heaters and injection nozzles to increasing runtime with a full load.
PentoMag®, Pentol’s Magnesium technology, increases the melting point of vanadium, sodium and potassium, so these fuel components are actively suppressed. PentoMag neutralizes all condensing SO3, which reduces the exit gas temperature and increases efficiency by up to 2%. Any residuals remaining in the boiler will be water soluble and easy to remove during outages.
Benefits
To guarantee the long-term stability of the emulsion, Pentol uses a combined mechanical and chemical stabilization of the fuel.
PentoMuls® is a well-balanced blend of surfactants, dispersants and catalysts. PentoMuls cleans the fuel oil system by removing buildup and preventing deposits in fuel oil heaters, corners and valves. It also emulsifies and stabilizes water content. Tests have shown that heavy fuel emulsions remain stable for up to six months without separation of the water and the fuel.
Deagglomerating asphaltene in the emulsion reduces the demand for air pressure during combustion, which results in a corresponding reduction of NOx and SO3 emissions. We guarantee that PentoMuls will ensure emulsion stability for up to six months. This allows us to produce the emulsion either online just before the burners or offline in front of the storage or day tank.
Dosing Skid
The PMDS (PentoMuls® Dosing System) is the key to creating a stable water-in-oil emulsion.
Fully automatic production of water-in-oil emulsion with perfectly sized water droplets.
The PMDS includes a continuous, online measurement of the water content in the fuel. Therefore the water content is continuously adjusted to the fuel oil consumption and takes the natural water content of the fuel into consideration.
The PMDS can be connected to the DCS (distributed control system) for signal exchange.
