Hydrocyclone for Separating Immiscible Fluids and Removing Suspended Solids

Inventor(s):  Khalid A. Hashmi (Canada), Hassan A. Hamza (Canada), Kanti L. Kar (Canada), Martin T. Thew (United Kingdom), Wally I. Friesen (Canada)
Patent Expiry Date: 2018-04-29

Through research and extensive field testing at several Canadian oil company sites, CanmetENERGY has developed a new hydrocyclone that is specifically suited for treating difficult-to-separate oily emulsions such as those encountered in the secondary treatment of heavy oil production fluids. The new CANMET hydrocyclone embodies a number of unique design advances, including an adjustable overflow orifice and the capability to remove suspended solids in a separate stream.  It also lends readily to on-line monitoring and control. The new design has already proved highly effective in treating heavy oil production fluids and has demonstrated the potential to deliver significant cost savings when installed as a replacement for conventional treatment technologies.

Recognizing the potential of hydrocyclone technology to handle a wide range of separation problems, CanmetENERGY Centre Devon introduced CANMET hydrocyclone as a cost-effective alternative to conventional treatment trains in national and international heavy oil industry. CanmetENERGY worked closely with Prof. Martin Thew of University of Southampton, U.K., who pioneered the original hydrocyclone designs that are now in widespread use in offshore oil production.

Pyrolysis Liquid-In-Diesel Oil Microemulsions

Inventors: Michio Ikura, Siamak Mirmiran, Maria Stanciulescu, Henry Sawatzky
Patent Expiry Date: 2018-07-03

The Bio-oil Diesel Microemulsions (BDM) process produces a stable bio-oil/diesel fuel mixture with properties similar to those of No. 2 fuel oil. It used to be that bio-oils were insoluble in No. 2 diesel oil. Mix the two and they formed two separate phases. Now an effective process for mixing them is available: the BDM Process. Once mixed by this process, the two oils form a blend that is stable and easy to ignite. The BDM Process produces a bio-oil/ diesel fuel mixture with properties similar to those of conventional diesel fuel. Most boilers, turbines and power generation stations can use this blended fuel without major modifications. The BDM Process has also been used effectively to blend heavier fuel oils, such as No. 4, with bio-oils. This added benefit will greatly accelerate the penetration of blended bio-oil fuels into existing oil-fired facilities that are used to generate electricity. The use of the BDM Process could result in a significant savings in fuels costs depending on the fuels blended and on their relative proportions.

Preform for magnesium metal matrix composites

Inventor(s): Jason Sin Hin Lo, Areekattuthazhayil K. Kuriakose, Raul Santos
Patent Expiry Date: 2019-07-19

Lightweighting engineering structures and components are effective means in reducing energy consumption in the transportation industry.  Magnesium alloy being one of the lightest engineering alloys appears to provide the solution.  However, though magnesium alloy has the advantage of low weight, its disadvantage is in its low mechanical properties compared to other engineering alloys.  In order to compensate for this weakness, reinforcement/reinforcements can be added to the alloy to form a composite, which would have much superior mechanical, physical or other properties.  Typical reinforcements include carbon, graphite, silicon carbide, titanium diboride, boron carbide and boron nitride.  The major challenge in the fabrication of magnesium matrix composites by the effective squeeze casting route is that magnesium is extreme reactive, often undesirable products are formed with a binder in the fabrication process ( a binder is used in the preform to hold the reinforcements in homogeneous distribution in the squeeze cast component).  These products would lead to inferior properties of the squeeze cast product.

This invention seeks to provide a process for preparing a preform for a magnesium metal matrix composite which involves the use of a preform binder which is unreactive with molten magnesium, does not cause the creation of undesirable solid materials in the magnesium composite, and which can be used with the reinforcing materials. In addition, this invention also seeks to provide a process for preparing a preform useful in composites in which the metal is not magnesium, such as aluminum and aluminum alloy composites.

Candes Plus

Inventor: Michio Ikura
Patent Expiry Date: 2030-09-03

Research at NRCan in the field of oxidative desulphurization of diesel fuel has led to the development of CANDES Plus, a process resulting in cetane numbers up to 157.  The current practice for increasing a cetane number in diesel fuel is to add a small amount of alkyl nitrates which gives, at best, a cetane number increase by 8. Biodiesel has a cetane number ranging between 60 and 70. CANDES Plus builds on CANDES, a patented NRCan technology, which could be installed in or beside any petroleum refinery.
