Incorporation
of upto 5-20% water in Fuel Oils such as diesel and furnace
oil is known to improve the fuel efficiency and reduce pollution.
Both the particulate matter and the nitrogen oxide in the
exhaust are considerably reduced. Although the concept is
known since the turn of last Century, the Technologies have
been developed and commercialized in the West in the last
2-3 years. Some American Companies have already entered this
Country and are operating such plants.
MAMKO have studied the system and, developed Water/Fuel Oil
Emulsion Technology, to meet this objective. The water incorporation
in Fuel Oils is effected by a process called emulsification.
It is the emulsification of water droplets into the fuel oil.
The key to achieving maximum efficiency is to produce droplets
as small as possible. Here we offer the technology for Fuel
Oil such as Furnace Oil and LDO.
The Emulsification may be implemented at any one of the following
three stages; namely :
(a) At Consumption Stage
Here the oil is emulsified just before the use that is just
before the entry to the Boiler or a Diesel Engine as the case
may be.
(b) At Buffer Stage
Generally there is a buffer storage where the material is
stored before the use. For example, when a Truck driver fills
his tank at a Petrol Pump his tank is his buffer storage.
Also a boiler operator stores his fuel in a tank and uses
it as and when the boiler is fired. The storage tank is a
buffer storage. In these cases emulsification may be carried
out at the time of filling the buffer storage tank.
(c) At Manufacturing Stage
Here the emulsification may be carried out at the Refining
center prior to the distribution of the Fuel after the refining
of the given fraction. There is a fundamental difference in
the final products in the above cases. All f them differ in
the requirement of the period for which Emulsion should be
stable. The following Table gives the figures.
| Emulsification
Stage | Required
Physical stability period for the product | |
At Consumption stage |
Less than a minute. | |
At Buffer stage |
1 to 7 Days. | | At
Manufacturing stage |
2-5 Years. |
