Frito-Lay's Commitment to Conservation

Frito-Lay North America, a business unit of PepsiCo, Inc., serves as a role model for conservation for the conglomerate's other companies. At its production facility in Killingly, Conn., Frito-Lay installed a supplementary-fired HRSG from RENTECH to better manage its energy consumption and make it more competitive on the grocery store shelf. An important consideration in the industry is energy-per-pound of product. More

CHP replaces fired boilers at Smith College

When Smith College in Northampton, Mass., decided to renovate and reconfigure its central heating plant and steam distribution system originally built in the 1940s, it installed a vertical-design HRSG and a low-emissions packaged boiler from RENTECH. Now Smith College produces power onsite in a reliable operation that satisfies some of the nation's most challenging environmental standards. More

HRSGs for small plants

Mention HRSG and most people in the power business think of triple-pressure units in service at large combined-cycle plants. But drop in size to HRSGs serving in small combined-cycle and cogeneration plants (those powered by GTs producing up to about 60 MW), and it's another world in unique design variation. A leader in the supply of drum-type boilers for GTs rated up to 60 MW is Rentech Boiler Systems. More

Backup steam supply is critical for Calpine

In some areas of the country, a merchant plant capable of generating and selling only electricity can have difficulty turning a profit. Add a thermal contract and the revenue stream can change dramatically. However, a thermal contract means you must supply steam even when the gas turbine (GT) portion of the combined cycle or cogeneration plant is forced out of service. More

Self-generation at ASU

Many large consumers of electricity, including municipalities and universities, are considering the benefits of self generation because of the spiraling cost of energy. Arizona State University's new combined heat and power plant includes an HRSG from RENTECH to stabilize power costs and guarantee a reliable supply of electricity, steam and chilled water. More

Reduce emissions in Texas

A chemical plant in Texas selected RENTECH to help reduce pollutant emissions. Four packaged steam generators from RENTECH were designed with minimal refractory to enable rapid startups and SCR to assure emissions compliance. The plant's new cogeneration system allowed the company to retire its old steam generators and meet its compliance schedule. More

Energy for Corona

Corona, a city of about 125,000 people in southern California, established a municipally-owned power generation company as its answer to the state's energy crisis. The goals included providing a reliable source of electricity, stabilizing costs, and controlling emissions. RENTECH developed a HRSG for this unique project to reduce installation time and cost, facilitate maintenance, and perform to the customer's requirements. More
