Case Study #1: Glass Furnace Exhaust for
Container and Flat Glass Manufacturing
Glass Melting Furnaces. Applications where several pieces of conventional equipment
struggle to attain only marginal efficiency provides an opportunity for the Cloud Chamber Scrubber
(CCS) to showcase its unique capabilities as a multi-pollutant device. Container / flat glass
manufacturing is a typical example.
Following other successful applications in the glass industry, a pilot study to evaluate the
performance of a Cloud Chamber Scrubber (CCS) system was performed at a major glass
company. The purpose of the study was to evaluate the ability of the CCS to treat emissions
from the exhaust of a glass melting furnace for both particulates and SO2. The test was deemed
successful, and Tri-Mer received an order from the major glass company based in part on the
pilot study, which showed the ability to meet requirements set by state and federal regulatory
authorities. A third-party testing company was contracted by the glass company to source test
the inlet and outlet of the CCS using EPA Method 5/202 for particulates.
of these tests are proprietary. Other tests conducted independently by Tri-Mer Corporation,
using standard methods modified for the circumstances, showed that the CCS could remove
total particulates in excess of 95%. A summary of the tests conducted by Tri-Mer utilizing
modified methods is shown below.
CCS Emission Data for Glass Furnace Exhaust:
Oxy Fired Glass Melting Furnaces, Total Particulates
Graphic 1. Performance results on container flat / glass manufacturing showing over 95% capture of
total particulate, both filterable and condensable. These were conducted by Tri-Mer using a modified
Method 5 to account for “drift water,” an artifact of the equipment set-up.
CCS Typical Removal Efficiency for Sulfur Dioxide (SO2)

Removal of SO2 was a requirement of the system.
For removal efficiency tests, third party testers employed continuous emission monitors (CEM)
for SO2. A variety of applications verify that typical SO2 removal in the CCS is in excess of 99%
as shown in graphic 2 above. As an enhancement, a method for minimizing or recycling treatment
of the waste stream for soda glass was proposed by Tri-Mer. This is called the Zero Discharge
feature of the CCS system for glass applications.
Wet scrubbing of soluble gases is well understood. Tri-Mer Corporation, as a leader in wet
scrubbing, has thousands of scrubbers of different types installed in many industries. The CCS,
by utilizing charged droplets, can remove fine particulate that other wet scrubbers cannot,
while retaining the gas scrubbing ability of a packed tower scrubber.
