Odorants Atmospheric Dispersion Forecast around a Pulp Mill Plant

on .

sesion04 cartelle04   Traditionally, pulp mill plants using Kraft process produce TRS (Total Reduced Sulphur) odorants emissions; this is the case of ENCE-Pontevedra plant.

   In this work, PrOlor operational system for odorants atmospheric dispersion forecast is presented, based in WRF/CALMET/CALPUFF models, and applied to prevent sporadic odor episodes around that plant.

PrOlor: Forecasting Odors Two Days beforehand. Case Study of An Animal By-Product Processing Plant.

on .

sesion04 diaz02   PrOlor is the first commercial software application in the world that is able to forecast an odor incident two days beforehand by using advanced dispersion modeling and odor measurements at the source.

   PrOlor tool was used to forecast odor incidents during 10 months in a rendering plant. The results are shown in this article.

A new update on CALPUFF. The version 7 of this lagrangian model is here.

on .

calpuff v7   The 22nd of June 2015, a new version of the CALPUFF software has been released. The Version 7 of the CALPUFF modeling system contains many new features. The model updates introduce new source types including roadways and flare modeling. The new pre-processor SURFGEN which can process sub-hourly ASOS data and the post-processors CALRANK, CALAVE and CALMAX are also now available.

   This version 7 includes all the new features introduced in Version 6 (which is now being deprecated), such as the ISORROPIA (now updated to v2.2) inorganic gas-particle equilibrium model, aqueous phase chemistry and an anthropogenic secondary organic aerosol (SOA) module based on the CMAQ/MADRID model; options to use sub-hourly time steps for both meteorological and emissions data, nested grid capabilities; an option in CALPOST to compute daily peak one-hour concentration values consistent with the new U.S. 1-hour SO2 and NO2 standards.
