The rise of the salty water table in many areas of Australia is threatening a large area of agricultural land. In a two-year research, development and demonstration project, scientists have been looking for ways to solve the problem by producing fresh water as a valuable byproduct of salinity mitigation. The Renewable Energy Group of RMIT University's School of Aerospace, Mechanical and Manufacturing...

    Why do governmental bodies regulate VOC (volatile organic compounds) emissions? Because these compounds react with nitrogen oxides to produce ground-level ozone. VOC emissions have many names: hazardous air pollutants (HAPs), non-condensable gases (NCGs), or just plain “organic vapors.” Examples of such emissions in the chemical process industries (CPI) include gasoline and diesel...

    Regenerative thermal oxidizers (RTOs) are commonly used for controlling volatile organic compound (VOC) emissions from a broad spectrum of industries. An RTO is basically a thermal oxidizer that uses ceramic media as the heat exchanger medium, providing high heat recoveries. Over the past few years, much attention has been given to the pros and cons of the different types of ceramic media...

Although there has been big surge in biodiesel production recently, such fuels are not without problems of their own, such as low mileage, poor performance at lower temperatures, and adverse effects on engine components. Also, the production process for making biodiesel — the methyl esterification of fatty acids derived from vegetable oils (such as palm and rapeseed)...

    When in 1997 a United Nations’ conference at Kyoto, Japan, called into being the Framework Convention on Climate Change (UNFCCC), it seemed that greenhouse-gas emissions regulations were just around the corner. Not so fast, was the world’s answer. The United States — after originally supporting the so-called Kyoto Protocol — turned around and rejected the treaty, which...

Hardly a day goes by that there is not some story in the daily press related to climate change. This was especially true last month, due to the United Nations Conference on Climate Change taking place in Nairobi, Kenya (November 6–17). Personally, I’ve become desensitized by daily reports about “the latest scientific findings” citing evidence either for or against the premise that...
