CR Clean Air Group has thousands of installations across the world addressing these core contaminant applications,” he says. The company designs and offers wet scrubbers, packed-tower scrubbers, and high-energy Venturi scrubbers to meet a variety of applications, ranging from arsenic and zirconium tetrachloride to chemicals like trimethylamine and dimethylamine, says Tebaldi (Figure 1).
