By conducting energy assessments of their steam systems, chemical plants can uncover important opportunities to improve energy efficiency, which leads to significant energy savings, lower emissions, and better productivity.  \nSummary  \nIn late 2005, a Save Energy Now energy assessment was performed at Dow Chemical’s St. Charles Operations petrochemical plant in Hahnville, Louisiana. The main objective was to identify opportunities for natural gas savingsin the plant’s steam system. The assessment, performed by U.S. Department of Energy (DOE) Energy Expert Riyaz Papar of Hudson Technologies, quantified several opportunities for increasing steam system efficiency. By capitalizing on some short-term opportunities, the St. Charles plant achieved impressive natural gas savings.  \nThe personnel at the St. Charles site improved their steam trap program and enhanced their ongoing leak repair campaign. Although Dow was aware that the efficiency of these systems could be improved, the assessment quantified the potential energy savings in a manner that made it more compelling to implement the improvements. The combined annual energy and cost savings resulting from these two efficiency measures amount to 272,000 MMBtu and $1.9 million, respectively. With project costs of approximately $225,000, the simple payback was around six weeks.  \nProject Drivers  \nTo meet their corporate energy efficiency goals, employees at the Dow St. Charles site knew that they needed to act decisively. The analysis conducted using DOE’s Steam System Assessment Tool (SSAT) identified the magnitude of energy savings that were possible from repairing the failed steam traps and leaks. This validated and increased attention on the company’s steam trap maintenance and leak repair policy. The savings opportunities from repairing the steam traps and leaks quantified in the Save Energy Now assessment encouraged the plant to replace the failed traps immediately and bolstered the steam leak repair program. This decision was justified by the energy savings achieved by the plant.  \nA utility pipe rack at Dow Chemical’s St. Charles Operations in Hahnville, Louisiana.  \nCompany and Plant Background  \nDow Chemical Company is a diversified company that offers a wide range of chemical, plastic, and agricultural products and services in many essential consumer markets. With customers in more than 175 countries and 42,000 employees around the world, the company has annual sales of $46 billion. Over the past 30 years, Dow has been proactive about energy efficiency. In 2005, the company established agoal of improving its energy intensity by 25% by 2015.  \nFormerly owned by Union Carbide Corporation, the 2,000-acre St. Charles facility has been in operation since 1966 and produces glycol ethers and amines. With nearly 3,000 employees, the St. Charles site produces approximately 10 billion pounds of these intermediate chemical products annually.
