Separations in Mining and Oil Sands Operations

Separation of water from fine tailings in mining and oil sands operations has been a challenge.  To speed water recycle, the density of dispersed particles is increased to form sediments. Continue reading

Best Practice For Inline Particle Size Characterization

 Chemists, engineers, and biologists are often challenged by processes involving particle or droplet systems. Solid or liquid dispersion, homogenization, agglomeration, or precipitation can create variability in product stability and manufacturing throughput. To develop and manufacture world class products at competitive costs, scientists and engineers use inline particle size measurements to optimize process conditions and consistently meet product quality specifications, at the bench or in manufacturing. Continue reading

AIChE Annual Meeting 2012

I’m really looking forward to attending the annual American Institute of Chemical Engineers (AIChE) meeting in Pittsburgh, PA this year. It is always a great opportunity to meet excellent scientists working in very diverse areas. As a chemical engineer it is also nice to focus on chemical engineering for a change! – since many of the conferences I attend are chemistry orientated.

It is also great to see so many papers being presented that Continue reading

Analysis of Particle Sizes in Process Workshop

The Analysis of Particle Sizes in Process: Measuring Techniques for Emulsions and Suspensions Workshop takes place this week (October 10-12) at the University of Potsdam Institute for Chemistry.  This workshop not only focuses the theory of particle size but also the technology that can be used for real-time, in-process measurements. One of the most interesting sessions will be on the emerging areas where particle size is gaining traction – particle measurement in biotechnology. Continue reading

HANBAT International Workshop on Industrial and Pharmaceutical Crystallization

Crystallization is a complicated process where the final crystal product is a function of thermodynamics as well as kinetic and physical phenomenon. Continue reading

Oil-Sands and Tailing Settling and Water Recycle

Alberta, Canada is home to massive deposits of oil sands, estimated to contain approximately 300 billion barrels of recoverable bitumen. However, byproducts of the oil recovery are tailings which include a mixture of water, sand, silt, clay, and residual bitumen. To minimize environmental concerns posed by tailing ponds, it is important to separate tailing solids to ensure efficient water recycle and speed water recovery process.  Continue reading
