Steam System Optimization : A Case Study

The steam system optimization (generation, distribution, use and condensate return) offers a large opportunity for action to comply with the new levels of energy efficiency standards. Superior design and improved maintenance practices are the two main sources of savings in steam systems. Increased competition no longer permits an industry to survive with energy waste that could be eliminated. This paper highlights the study findings of the steam system in a plant from the Food industry. The steam system operates with an annual budget of $1.9 million. Normal steam demand ranges between 80,000 to 85,000 lb/hr. The steam system analysis identified energy savings worth $270,000 per year. The optimization measures were in two categories: • No cost/low cost optimizations that can be done through a better maintenance and improved operating condition • Major improvements that require a significant investment, and includes the modification of the process and major equipment
