Chemical Plant Replaces Bag Filters-Case Study
PROBLEM. A large US chemical plant that manufacturers monomer for paint coatings was spending more than $90,000 per year on bag filters. The bag filters were supposed to remove catalyst carry over from the batch reactor. Problems arose with the bags breaking and by-pass from poor sealing. Two batches per day was maximum production. SOLUTION. Pentair analyzed their process and recommended it 's V-MAX Technology. V-MAX is a coreless element that flows from the inside-to-the-outside like a bag... (read more)

Removing Dissolved Gases without using Chemicals
It is commonly known that dissolved gases such as CO2 and O2 can oxidize and destroy metal piping and system components. Corrosion control and prevention is essential to avoid the large cost associated with replacing boiler tubes, old pipes and corroded equipment. The life time of metal components can be extended and plant downtime can be minimized by adding a small compact membrane degassing system that controls dissolved gasses and prevents corrosion. Historically, oxygen scavengers might... (read more)
