Treatment of emissions generating annoying odours in a turkey by-products processing plant

on .

GAroca   The processing of meat by-products for the production of protein meals entails the generation of gaseous emissions causing annoying odours that cause a severe environmental impact in the surrounding populations.

   This work presents the characterization of the main components of the process emissions, the dimensioning of the treatment system and the results of the operation of a rendering plant of turkeys, where fractions, such as viscera, blood, feathers, as well as seizures and discards, are processed to produce flour and oil for animal feed. This plant has a processing capacity of 8 million turkeys per year and a projection of 12 million.

Comparative between PLUME VDI 3940-2 method and CALPUFF atmospheric dispersion model application

on .

MZacarias   Chile is a country that has different industrial activities generating annoying odors for the communities that live in the surroundings. It seeks to determine the area of impact caused by odors, for which measurements are made with suitable panelists (according to the established in the chilean normative NCh3190: 2010).

   To determine the area of impact, plume measurements are made in accordance to VDI 3940 part 2. On the other hand, the mathematical model of atmospheric dispersion CALPUFF fed with emissions measured by dynamic olfactometry is applied.

Biogas treatment with recovery of nutrients from centrate in an outdoors high rate algal pond through algae-bacteria systems

on .

D_Marin   The upgrading of biogas coupled with centrate treatment was evaluated in an outdoors photobioreactor interconnected to an absorption column of CO2 and H2S from September to December 2016.

   The maximum recorded CH4 concentration in the biomethane was 94%, with total removal of H2S and removal efficiencies of CO2 ranging from 70% to 90% depending on the environmental conditions.
