Environmental compliance challenges

D. Shangguan, Lead-Free Transition and Environmental Compliance Challenges Ahead for the Industry, Global SMT Packaging, Sept 2004... 

Due to strict environmental regulations, turbine engine manufacturers and users are facing great challenges in reducing NO, SO , CO, and hydrocarbons to meet the compliance limits. To date, several innovative methods have been developed and introduced into the market to combat these problems. However, often, while reducing NOj, or other pollutants, new problems arise. These problems are lower turn-down ratio, poor thermal efficiency, flame instability, uneven temperature distribution in the combustor, and noise. These problems are even more pronounced in a liquid fuel fired turbine combustor. Therefore, the present research...

All of the above, particularly those parameters or factors that affect surfactant properties, which make up 10-30% of detergent formulations, as well as sustainability and environment-related properties of the formulation components [7,8], are expected to play a key role in their application. Consequently, the challenge ahead is not only to formulate concentrated cleaners and surfactant-based detergents but also to ensure the providing of environmentally friendly technologies that deliver the benefits customers have come to expect at a cost they are willing to pay while in compliance with sustainability.
