from asphalt plant aggregate dryers [1]. Spray towers have lower capital costs than other wet scrubbers. Also, spray towers generally have lower power consumption and are not prone to fouling, so operating costs are also lower [5]. Operating costs of spray towers increase for fine PM applications, because such
