TL;DR: In this paper, a spray tower is used to spray water contg. alkali materials in waste gases, capturing dust and the product of reaction with a collision type preduster then heating the gases and feeding the same to a dust collector.
Abstract: PURPOSE:To improve desulfurization rate and to reduce the consumption of calcium hydroxide by spraying water contg. alkali materials in waste gases, capturing dust and the product of reaction with a collision type preduster then heating the gases and feeding the same to a dust collector. CONSTITUTION:After part of high temp. waste gases are branched and are introduced into a drying chamber 12, they are returned into an introduction duct 2, and are introduced together with other waste gases into a spray tower 1. Slurry of calcium hydroxide, etc. are sprayed from a spray nozzle 4 and are caused to react with S compds. in the gases and the temp. of the waste gases is reduced down to within 15 deg.C of saturation temp. The product of the reaction and the coarse particles in the dust are captured in the tower 1 and a collision type preduster 13 moving in a drying chamber 2, whereby they are dried and separated. The waste gases contg. fine dust and the product of reaction are heated by heat exchanging with the preduster 13, and are introduced through a discharge port 10 then through a discharge duct 7 into a dust collector 8.

TL;DR: In this paper, the authors examined the spray drying process of α-olefin sulfonates and discussed important parameters and considerations in that spray-drying process, and an examination of the product from the spray tower.
Abstract: This paper examines the spray drying process, particularly the spray drying of α-olefin sulfonates. Topics covered center on the spray drying process for α-olefin sulfonates, important parameters and considerations in that spray drying process, and an examination of the product from the spray tower. Product development from laboratory to pilot plant is described with attendant translation to full-scale facilities. At least 4 different cocurrent spray-drier units are illustrated and key parameters are discussed.
