CONTACT SUMMARY: j 

Mr. Cowly called in order to obtain information about the development of the vapor suppressed 

resin test method. He indicated that because the suppressed corrosion resins that DOW sells are 

sold with the vapor supressant already added, DOW would need to run the test for its customers. 

During the conversation, we talked about the types of corrosion i ssistant (CR) applications that 

require resins that contain high quantities of hazardous air pollutants (HAP). Mr. Cowry indicated 

that only equipment made for alkaline senary He thought that under the 

averaging scheme, it would be possible for facilities to use M8%JJtAP content resin (an example 

of a high HAP resin) for such an application because they cf3uTEaverage it with a lower HAP 

resin for another CR appUcation. (_^ y itAP/" -^ A ' 'e***~~J^

DERAKANE Epoxy Vinyl Ester Resins - Case History 

CUSTOMER 

Louisiana Pacific 

Samoa, California 

EQUIPMENT 

Piping that leads into a chlorine 

dioxide (ClO^ updraft tower in a 

pulp bleach plant. This fiber-reinforced plastic (FRP) piping measures 

9'-3" long with a 24"-diameter, and 

has a standard 90° elbow with flange 

on one end and standard 150-lb. 

full face flange on the other. 

OPERATING CONDITIONS 

A stock pump is used to convey 

the pulp through the piping into 

the tower. The piping handles two 

alternating processes with pH 

ranging from 3-12. 

The mill previously used a .5 g/1 

C102 solution at 150°F with a pH 

of %A. However, two solutions are 

now being alternated in order to 

begin reducing chlorine dioxide 

within the bleach plant. The alternate process uses a 2.4 g/1 sodium 

hydroxide and up to 1.0 g/1 hydrogen 

peroxide solution at up to 210°F with 

apHof 12. According to Byron 

Wilson, pulp mill superintendent, the 

mill was totally chlorine-free by 

September 1995. 

CONSTRUCTION 

The piping is fabricated with 

DERAKANE' 441400 Epoxy Vinyl 

Ester Resin. The 125-mil corrosion 

barrier consists of two layers of 

This FRP piping handles both the low pH of chlorine dioxide and the hish pH of sodium 

hydroxide/hydrogen peroxide at temperatures up to 210°F. 

Nexus* veil, followed by 1.5 ounces 

per square foot of chopped strand 

mat. The structural layer is hand 

Iaid-up to total thickness of 1". 

The outer layer consists of one 

surface coat with an ultraviolet light' 

inhibitor. The piping was post-cured 

for 4 hours at 180° F. 

THE DERAKANE RESIN 

SOLUTION 

"We needed a resin that was versatile 

enough to handle both the low pH of 

chlorine dioxide and the high pH of 

sodium hydroxide/hydrogen peroxide," said Wilson. 

According to Stacy Mitchell, designer 

/estimator for Lape Industrial Fiber* 

glass, Inc. DERAKANE resin was 

selected because of its ability to 

handle the range of chemical solutions and temperatures required in 

this application. 

Wilson agreed that DERAKANE resin 

offers advantages for this service. 

"The fact that we can use it under 

such extreme conditions is certainly 

one of the benefits. We've been 

pleased with its performance," he 

noted.

SERVICE YEARS 

The piping was installed in December 

1992, and was reported in good 

condition in January 1996.
