Olin : Conserving Resources With Optimized Washing Process

CONSERVING RESOURCES WITH OPTIMIZED WASHING PROCESS IN FREEPORT

This sustainability story is one of many that shows how Olin products, technologies, ideas, and people are having a positive impact on our world.

SUSTAINABILITY CHALLENGE

1. At its Freeport plant, Olin uses diaphragm cells for electrolysis to separate caustic, chlorine, and hydrogen.

1. The diaphragm cells must be cleaned regularly to remove hardness and impurities.

1. This cleaning process was carried out continuously, requiring river water and CO2.

OLIN'S SOLUTION

1. As result of a continuous improvement process, a project was initiated to optimize the cleaning of the diaphragm cells.

1. A soak-wash process was introduced, in which the cells are cleaned in a batch process rather than continuously.

1. This cleaning only needs to be done when the caustic strength gets lower.

DID YOU KNOW?

POSITIVE IMPACT

1. Due to the more efficient cleaning of the diaphragm cells, significantly less river water and CO2 is required for the process.

1. This saves up to 13 million gallons of water and 50 tons of CO2 per year, protecting the environment and conserving resources.

Olin is North America's largest producer of electrolytic hydrogen and is continuously increasing its green hydrogen percentage.
