Yaz- Dehydrone is a unique invention ,
patented in the U.S. and Canada, has the potential in revolutionizing the two-
phase separation technology. Although it utilizes centrifugal separation , which
is a well known and widely used method , but it is unique in design and method
of operation. It is expected to strongly compete and eventually replace other
types of centrifugal separators presently used in the industry.
2- THE INVENTION
YAZ- DEHYDRONE is a completely new and more efficient method of separation
adaptable to any operation. With no internal or external moving parts, it
requires little or no maintenance and little or no additional energy, if the
fluid is in a flowing state.
A broad patent coverage for the DESIGN and METHOD of
separation has been granted by the U.S. and Canadian Patent offices.
3- THE VESSEL
The Vessel is made from a central cylinder around which a
pipe is wound in a spiral form. From the spiral pipe, at specified turns,
precise openings are made with leading pipes to the central cylinder. These
openings are traps for directing the heavy phase into the central cylinder. The
central cylinder has a level control and a dump valve for discharging the heavy
phase as it reaches a specified level inside the cylinder. A hatch at the lower
end of the central cylinder is installed to remove any solids that may
accumulate with time .Also, this hatch is put to remove solids when separation
of solid/ liquid or solid/ gas is desired.
4- HOW THE SEPARATOR OPERATES
The mixture of two- phase fluid, in this case water in oil,
enters the vessel at the lower end of the spiral pipe and moves upward in a semi
circular motion through the pipe.
For the fluid to flow inside the vessel , if not induced by
the natural flow of the well, a small pump is used for that purpose. An inlet
pressure of 100 psi is normally sufficient.
As the fluid moves through the spiral pipe, the water
droplets ,being the heavier phase, are forced by their motion within the pipe to
the outside portion of the flow. The water droplets are, also, forced together
and coalesce forming a water stream flowing on the outside portion of the flow.
As the whole fluid flows further , the water is caught by the first trap and
directed to the central cylinder, This happens without any turbulence to the
main flow, because the design of the central cylinder is made to operate as a
collection vessel and as a stabilizer to the main flow. In addition , the traps
are also designed that no turbulence occurs when the heavy phase is directed
As the fluid flows further, any water that had not
separated would separate and is caught by further traps alongside the spiral
The main separation by centrifugal force occurs in the
spiral pipe and the heavier phase is directed to the central cylinder. Further
separation, however, occurs in the central cylinder for any portion of the light
phase that may have entered with the heavy phase through the traps. This happens
by gravity segregation and the light phase is re-introduced into the main stream
near the exit point.
In principle, Yaz-
Dehydrone is a centrifuge with no moving parts, with no
need for power supply to operate a rotating vessel, with no need of regular
maintenance of the different parts and it is manufactured at a fraction of the
cost. Furthermore , it can deal with mixtures of liquid and gas or solids and
gas which centrifuges cannot do.
Yaz- Dehydrone can separate any two-phase mixtures
,regardless of their concentrations or fluctuation in their concentrations in
5- MANUFACTURING COST
A U.S. manufacturer, based in Ohio, has provided an
estimate for manufacturing the first Unit and has estimated 30 to 60 days to
construct the Unit.
The vessel manufacturer has been manufacturing pressure
vessels since1901 and their manufacturing standards meet ASME Boiler and
Pressure Vessel Code and it complies with ANSI. Blue prints, bill of materials
and manufacturing costs are all available and any other manufacturer can build
the vessel based on this information.
Because the vessel is made of only steel pipe and a central
cylinder and few instruments, the cost is extremely low compared with the sale
price that is expected to obtain, considering other separating equipment in the
market, which are sold at prices of $200,000 and $350,000 or more. Yaz-Dehydrone can easily
compete with these prices and have an exceptionally high margin of profit , in
addition to giving superior results.
6- ECONOMIC PROJECTIONS
The initial intended market for the Separator is the
International Petroleum Industry
With the expansion of the global economy, the need for
two-phase separators for new facilities is constantly growing. In addition more
oil wells are being depleted into producing formation water or injection water
with their crudes, which need to be separated. Requirements to replace the
presently inefficient separators or too expensive to operate or maintain, will
also contribute to continuous demand.
The total direct market is projected in excess of $ 3
billion. In addition to the oil industry, other separation processes are largely
hidden from the average consumer. These processes are a part of many industries
from mining to food processing to various manufacturing. The combined U.S.
,Canada and European markets for various separation equipment which are used in
liquid/ liquid, solid/ liquid, solid/ gas and liquid / gas is estimated at over
$ 3.5 billion . Yaz- Dehydrone can easily get a small share of the market in the first three years
which would amount to many million dollars. In a prepared Business Plan The
expectation of sales was estimated at $100 million at the end of 5
Market efforts should focus on replacing two-phase and
three-phase separators used in Oil and Gas operations. Target market should
include offshore production ,where deck space in addition to efficiency is of
primary importance ,in addition to onshore, exploration and
because of its simplicity, efficiency, ease of operation, low manufacturing cost
and little or no maintenance cost should be able to target new customers and to
compete and eventually replace many of the presently used separators because of
their lack of efficiency or to their high initial cost and their high operating
and maintenance costs.
It is envisaged that Yaz-Dehydrone, with aggressive marketing
and further development would suit all different separation needs and would
establish a permanent presence in the separation industry with a large share of
