What opportunities for managing energy costs and GHG emissions are commonly found in industrial plants?
• Compressed air systems are expensive utilities in industrial facilities. Their energy demand can be replaced by application of electric drives, impeller mixers and energy efficient blowers, and reduced by smart changes to distribution systems, machine controls and improved maintenance practices; • Steam boilers and distribution systems are less efficient than direct-fired heaters for many applications. Reducing or replacing steam demand can save considerable energy costs and eliminate the need for expensive maintenance practices; • Newer reliable variable speed drives and pressure flow controllers can drastically improve the part-load performance of ammonia chilling plants; • Monetary incentives, for example, cash rebates and tax incentives, from governments and utilities for renewable energy and energy efficiency projects are more valuable than ever before; • Aging rooftop HVAC equipment serving many facilities was specified and installed based only on lowest first cost.
