On Earth Day this year, the Zaandam cruise ship of the Holland America Line set sail from Vancouver, B.C., with revamped emission technology. In cooperation with several U.S. and Canadian government and regulatory agencies, the cruise line launched a technology demonstration project designed to show the feasibility of using sea water to “scrub” or reduce engine emissions on ocean-going vessels. “This is a ship like no other in the cruise industry,” says Stein Kruse, president and CEO of Holland America Line. “After studies and modifications of the ship’s new test emissions technology, it could dramatically change not only the cruise industry, but the entire maritime industry by reducing ship engine emissions.”
The sea water scrubber system was developed by Krystallon, a subsidiary of BP. It uses the natural chemistry of seawater to remove virtually all sulfur oxide, as well as significantly reduce particulate matter emissions. The sea water is then treated to remove harmful components while the calcium carbonate in seawater renders the sulfur oxides harmless by converting them to sulfates and neutral salts.

A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
