CALGARY SUN: Shell shows off new technology

Frothing technique will reduce GHGs and water use, says company
By IAN WILSON,CALGARY SUN

Shell Canada is touting a new oilsands technology which it says will use less water and reduce greenhouse gas emissions.

The Calgary-based company said its Shell Enhance froth treatment technology will eliminate 40,000 tonnes of greenhouse gas emissions per year – improving efficiency by 10% – and it will require 10% less water.

Froth treatment is a process that removes dirt and clay from the oilsands, leaving bitumen suitable for upgrading.

Shell said its method will use higher temperatures to make the separation process happen at a faster and more efficient rate.

The technique was developed by Shell and federal government scientists at the CANMET Energy Technology Centre in Devon.

“Shell Canada’s commercialization of Shell Enhance demonstrates the importance of new technology in the responsible development of the oilsands to help meet Canada’s energy needs,” said Shell Canada president and CEO Clive Mather.

Natural Resources Minister Gary Lunn called the development “a great example of how governments and industry can work together to develop clean technologies.”

Along with reducing greenhouse gas emissions and water use, the technology is expected to result in other benefits.

Shell expects reduced costs due to construction efficiencies.

As well, essential equipment can be 75% smaller with the new technology.

Shell Enhance will be used in the first expansion of the Athabasca Oil Sands Project (AOSP), which was formally launched earlier this month.

The AOSP is a joint venture which Shell Canada has a 60% stake in, while Chevron Canada Ltd. and Western Oil Sands L.P. each own a 20% share.

Shell is one of Canada’s largest integrated energy companies.
