摘要

THE ENVIRONMENTAL performance of chemical plants has become increasingly important over the past decade, and is now possibly the most important constraint on plant design. The way that engineers cope with environmental factors has changed considerably in recent years, however. When environmental issues first came to prominence, the emphasis was on reducing emissions from existing plants by installing 'end-of-pipe' solutions, such as equipment to filter out particulates or absorb harmful vapours.
