- Learn about how Ecolab used a proprietary chlorine dioxide program at an Egyptian fertilizer plant to reduce water consumption, maintenance costs, corrosion rates, and chemical usage.
Detailed Description
INSIGHT
Egyptian Fertilizers Company (EFC) is a leading global producer and distributor of high-quality nitrogen fertilizer products and industrial chemicals that provides clean, environmentally sound solutions to its customers. Its Suez plant is one of the largest fertilizer complexes in Egypt, producing 1,400 tons a day of ammonia and 5,000 tons a day of urea. It has four different recirculating cooling water systems designed to manage critical process operations.
INNOVATION
One of the biggest challenges in open, recirculating cooling systems is a high risk of bacterial proliferation due to ammonia contamination and the high temperature of the cooling tower. This can lead to increased water, energy and chemical consumption as well as:
- Lower production
- Heat exchanger failure
- Microbiologically induced corrosion
- Loss of revenue
Nalco Water provided a comprehensive solution that included on-site expertise and PurateTM Technology, a patented, proprietary chlorine dioxide program that controls biologic growth in cooling towers and other industrial water treatment applications. The treatment program has helped the EFC plant reduce:
- Water consumption
- Maintenance costs
- Corrosion rates
- Chemical usage
In addition, overall plant performance has improved, and safety has increased, due to the replacement of volatile chlorine gas with stable and reliable Purate biocide technology.
