How do large and waste-heavy industries comply with environmental regulations and still stay in the black? The solutions to this complex technical challenge
begin with an understanding of where each type of waste
stream must go and how it can be profitably re-used if possible. At most industrial sites, waste streams include wastewater, solid wastes and air emissions.
A new proposed state-of-the-art facility that would utilize
large rotary kilns to manufacture a ceramic product needed to
be able to meet regulatory requirements to become a reality.
The design team at SSOE — a global engineering, procure-
ment and construction management firm — addressed all
three of the problematic waste streams. In doing so, it elim-
inated industrial wastewater discharges and reduced the pro-
duction and disposal of solid waste during the manufacturing
process. But the biggest win was in its solution for air emis-
sions, without which the proposed project could not have
Air Emissions Abatement
The production lines in this plant emit sulfur dioxide
(SO2), nitrogen oxide (NO2), acid gases and particulate matter (dust or PM). Technical issues with the clay material used
to make the ceramic product, until recently, have prevented
the reduction of these emissions using traditional emissions
control technology in this industry.
For the new facility, the manufacturer needed permits for
four production lines, each of which had to satisfy strict air
emission maximums. Traditional technology would entail
three separate emission control devices, one for each type
