Dual
Laminate Piping used in Chlor-Alkali Plant Expansion
Prolite recently
completed a multi-million dollar dual laminate piping project for
the most modern Chlor-Alkali Membrane facility jointly owned by
American and Japanese companies which applied Japan's Chlorine
Engineers Cell Membrane Technology.
This project used low
concentration magnesium and calcium CPVC liners with FRP
structural reinforcement for the anolyte piping which reduces the
possibility of "chlorine buttering" usually encountered
using styrene based vinylester resins.
The catholyte headers
and hydrogen separators for the 33% membrane caustic was
constructed from PP-B (block co-polymer polypropylene) liners due
to it's corrosion resistance to membrane caustic and it's
excellent long term resistance to chloride attack on the
thermoplastic welds. The polypropylene liners were reinforced
with fiberglass for structural strength.
This is a fast
growing specification for dual laminate piping for Chlor-Alkali
membrane technology companies worldwide.
