This document presents the information required by the Colombian environmental regulator as a requirement for a production system that has to do with the thermal treatment of animal by-products, specifically the tallow used for the production of solid soap of the company JABONES EL TIGRE Y LA ROCA S.A.

   For the elaboration of the study, an evaluative research methodology has been used with the purpose of evaluating the effectiveness of the system of control of atmospheric emissions by absorption in water with the scrubber of the company. Initially, the obligations imposed by the national authorities are identified through the regulations defined by the Ministry of the Environment and Sustainable Development.

   Sewervac new mathematical modeling tool for the sulfur ion allows to model the routes of the sulfide ion to identify at which points we will have the highest sulfide’s concentrations and consequently hydrogen sulphide (H₂S), the conversion rates of sulfur to hydrogen sulphide, the origin of the hydrogen sulphide peaks and what it can be done to avoid it.

   The continuous investment in R+D has allowed the company Sewervac to present 2.0 version, developing software that provides a much more graphic and intuitive data output.
