PRISM™ Programme
Styrene production provides multiple challenges to manufacturers such as corrosion and fouling that can negatively impact reliability, profitability, safety, and sustainability. The Nalco Water PRISM Programme provides cost-effective, less toxic treatment alternatives to commodity chemicals traditionally used in the industry, market-leading insights in styrene production and digital solutions.
The Nalco Water PRISM Programme offers a selection of polymerization inhibitors, green retarders and corrosion inhibitors to address fouling and corrosion control challenges throughout the plant.
Styrene Polymerization Control
Nalco Water addresses styrene polymerization with customized programmes that specifically target areas of the plant where unwanted polymer forms. Our innovative solutions and onsite technical expertise provide a comprehensive programme to help protect critical assets and achieve sustainability goals.
PRISM Polymerization Inhibitors
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 Programme Assurance
Nalco Water offers proprietary technology to detect the residual inhibitor chemistry by providing a measure of inhibitor consumption and programme optimization for greater reliability.
PRISM Green Retarders
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 Programme 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.
Maximise Polymerization Control
Best practice is to pair a true polymerization inhibitor with a slower-reacting polymer retarder to deliver optimal control for plant operations. The inhibitor provides control during normal production while the retarder provides unit protection during a plant upset or emergency shutdown. Contact your Nalco Water representative for details.
Styrene Corrosion Control
In styrene reactors, acid gases such as CO2 are formed and can cause corrosion in heat exchange equipment, vent gas compressor, water stripper, piping, and other associated equipment. This results in equipment damage, unplanned shutdown, and environmental release.
Nalco Water offers cost-effective corrosion inhibitors formulated to protect critical assets and improve reliability.
