MECS® DynaWave® Wet Gas Scrubber
This unique, high-performance environmental technology has applications in numerous industries. DynaWave® is the only wet scrubber that accommodates a variety of reagents and handles multiple functions in one process, including SO2 acid gas absorption.
Increasingly stringent air pollution controls require refineries, power plants, chemical manufacturers, and cement kilns to remove acid gases and particulate matter from flue gas before releasing it to the atmosphere. The DynaWave® Wet Gas Scrubber offers a proven approach. Featuring unique MECS® Froth Zone technology, DynaWave® is our preeminent solution for particulate removal, hot gas quenching, and acid gas absorption — all in one vessel.
Many industries gain competitive advantage, as well as financial benefits, by implementing DynaWave®. This innovative technology can pay for itself as it allows a facility to cleanly utilize a less costly fuel source, such as pet coke or high-sulfur coal. MECS® experts have installed the DynaWave® Wet Gas Scrubber at over 300 locations, in various industries around the world. The distinctive DynaWave® design is helping reduce air emissions and increase efficiency and cost-effectiveness in power generation, refining, cement production, and sulfuric acid plants, among other applications.
Four Functions in One to Reduce Costs
Most industry applications require a wet gas scrubber to perform two or more of the following functions.
- Quench incoming gas
- Remove acid gases
- Oxidize sulfites to sulfates
- Eliminate particulate matter
In many conventional scrubbers or simple caustic scrubbers, each function occurs in a different area of the vessel, or outside the scrubber altogether. The DynaWave® Wet Gas Scrubber is different from conventional scrubbers in that it handles all four of these functions in the same vessel. Three of the functions take place in a unique area known as the Froth Zone. The fourth function, oxidation, is achieved in situ in the vessel sump. No other scrubber is capable of this performance. Our straightforward approach reduces both capital and operating costs. Most importantly, it allows for minimal equipment inside the vessel, making DynaWave®an extremely reliable and low-maintenance scrubber.
Unique Features and Benefits
DynaWave® offers numerous benefits over conventional wet gas scrubbers:
- Virtually unpluggable, with large, open-bore liquid injectors and nonrestrictive, open vessels
The only wet scrubbing process that can use a variety of reagents, including:
- Sodium hydroxide, NaOH
- Calcium hydroxide, Ca(OH)2
- Calcium carbonate, CaCO3
- Magnesium hydroxide, Mg(OH)2
- And others
- Simple to operate
- Low maintenance
- High on-stream reliability
- Zero liquid effluent (using lime or limestone reagent)
Expert Solutions, Customized to Your Needs
MECS® engineering experts can customize DynaWave® for your specific application needs, as we’ve already done for many industries. Major companies in the metallurgical, power, cement, and many other industries currently depend on DynaWave® to meet their clean air requirements.
Sulfur Recovery Units (SRU)
SRUs recover a high percentage of the sulfur in off-gases for a broad range of applications in the refining, coal gasification, and natural gas processing industries. DynaWave® removes the rest, and can save the day when a tail gas treatment process goes into bypass.
Power Flue Gas Desulfurization (FGD)
DynaWave® offers an excellent solution for FGD applications in the power industry.
DynaWave® masters the challenges of high-inlet SO2 and particulate emissions in FGD applications for the cement industry.
The solutions DynaWave® offers to the TiO2 industry are based on over 30 years of experience delivering difficult application solutions.
This green industry looks to DynaWave® to meet its sulfur removal requirements.
