FRP Scrubbers for Corrosive Gas Cleaning — and Why Very Large Diameters Belong On-Site

Industrial gas scrubbing is one of the harshest duties for process equipment: acidic condensates, chlorides, oxidizers, slurry erosion, temperature cycling, and continuous operation. Material selection is often the single biggest driver of lifecycle cost and reliability.

Fiber Reinforced Polymer (FRP)—also referred to as GRP (glass reinforced plastic)—has become a proven solution for wet scrubbers and associated vessels and ducting because it combines excellent corrosion resistance with high structural efficiency at low weight.

What’s changing in today’s market is the scale: scrubbers are getting larger, and diameters in the 8–20 meter range create a new engineering and logistical reality. This is where on-site manufacturing becomes not just attractive, but often the most practical route to a safe, cost-effective installation.
