A spray tower is a scrubber which uses a liquid (typically water) to capture and remove pollutants and dust
from a gaseous stream. It is usually used to remove dusts and particulates before their emissions in atmosphere, due to its simplicity and low requirements.
The excel spreadsheet that I developed can be downloaded at the end of this article. It allows for a preliminary calculation of a single stage spray tower, by calculatin removal efficiency and pressure losses.
Inside the spreadsheet I’ve added a guide both in italian and english language to describe how to use it. The guide includes also an appendix in which it is described the calculation method used complete with bibliographical references. The guide is also downloadable as PDF separate file.
