World-Leading Sulfuric Acid Plant Processes
MECS® has a long and successful history in providing proven and reliable solutions to the sulfuric acid industry. Our solutions feature breakthrough technologies, many of which have revolutionized performance, quality and cost-effectiveness for the sulfuric acid industry. We offer complete processes and plant designs for sulfur burning, metallurgy, spent acid recovery, and wet gas sulfuric acid recovery (SULFOX).

DynaWave® Wet Gas Scrubbers
DynaWave® is the only wet gas scrubbing process that can use a variety of reagents and accomplish multiple functions — including SO2 acid gas absorption, quenching, particulate removal, and oxidation — all in one scrubber. A unique, high-performance environmental technology, DynaWave® has been implemented by MECS® in over 300 solutions worldwide, in various industries.

Brink® Mist Eliminators for Air Emissions Control
MECS® offers the industry’s broadest range of products designed to remove virtually any type of mist from any gas stream, including elusive submicron-sized aerosol mists. Thousands of our systems have been installed in hundreds of applications: from sulfuric acid to asphalt manufacturing, plastic extrusions, metalworking, and beyond.

Innovative Heat Exchange Technologies
MECS® gas-to-gas heat exchanger technology offers one of the most efficient means on the market for recovering heat from energy-consuming applications in a wide range of industries. Our flexible and modular fully welded plate heat exchangers (MECS-ThermoZ™)  or non-welded “floating” plate units (OCAP™) have delivered results in fertilizer, refining, non-ferrous metals, general chemicals, and coal gasification installations, as well as many others. For the sulfuric acid industry, we also offer a flexible and modular fully welded plate heat exchanger, MonPlex II™.
