Final version of GRAL 20.01 released and now it is open source!

on .

gramm gral 20.01   The Graz Lagrangian (GRAL) system is a Lagrangian particle model with a free Graphic User Interface (GUI) available in both Linux and Windows. The last beta was published last November and now the developers have released the version 20.01. The software is now open source under a GPL-3.0 license, so everybody is welcomed to contribute to the project. The source code, has been published in github.

    The Graz Lagrangian Model - GRAL - was initially developed in 1999, and has been used extensively in regulatory assessments and scientific studies. The initial driver for the development of GRAL was the need for a model that could deal with the frequent low-wind-speed conditions (< 1.5 m s-1 for up to 90 per cent of the time) in the inner-Alpine basins of Austria. According to the developers, there are around 600 users worldwide using, the GRAL/GRAMM system.

Determination of odorant compounds in the thermal-mechanical a drying phase of wastes from olive oil extraction

on .

P05I3   In the industrial production of olive oil, both solid wastes and those produced from their incineration are a serious environmental problem since only 20% w/w of the fruit becomes oil and the rest is waste, mainly orujo and alperujo. 

   A key aspect to transforming these wastes into an important source of energy such as pellets is to recognize the most appropriate time of the year for waste drying, with the objective of minimizing the environmental impact of the volatile compounds contained in the waste.

Air quality monitoring to establish and / or discard the origin of Quintero odor events

on .

P05I3   In Quintero Bay, an important industrial complex is located. Between August and September of 2018, air pollution events associated with odors occurred in the city of Quintero, resulting in intoxication of hundreds of people.

   To try to clarify the origin of these events, an air quality monitoring campaign was carried out in one of the companies of the industrial complex (ENAP Terminal Quintero), in addition to the chemical speciation of the fugitive emissions existing in the Quintero Terminal ENAP. The air quality monitoring was performed using an equipment to an EPAS HIM 6000 HAZ SCANNER, Environmental Devices Corporation, USA, capable of measuring the concentration of twelve contaminants including HTC and VOCs, while the chemical speciation was performed using a TORION T9 portable GC / MS, Perkin Elmer, USA.
