PRISM™ Program

Nalco Water offers polymerization inhibitors tailored to the specific area of the plant where fouling and undesired polymerization occurs such as post-reactor cooling, vent gas compressor or distillation process areas.

These cost-effective, fast-reacting, true polymerization inhibitors are proven in all technology licensors and styrene production processes. ;

Monitoring and Program Assurance
Nalco Water offers proprietary technology to detect the residual inhibitor chemistry by providing a measure of inhibitor consumption and program optimization for greater reliability.

Styrene manufacturers have traditionally utilized toxic dinitrophenols like DNBP as polymer retarders. These substances are also extremely water-soluble and produce NOx emissions when incinerated. As a result, government regulation around dinitrophenolic retarder chemistries is increasing along with the need for less toxic alternatives.

Nalco Water has developed Green Retarder technology to effectively replace highly toxic retarder chemistry with a more sustainable product that is less toxic, non-soluble in water, improves employee safety and reduces environmental concerns.

Monitoring and Program Assurance
To ensure adequate plant protection during an emergency shutdown, Nalco Water provides a proprietary test procedure to determine available protection time at a particular dosage.
