System for reducing CO2 concentration in closed atmospheres

A Galician university, in the north of Spain, has developed a system for reducing CO2 concentration in closed atmospheres. The system is especially useful in cockpits like rooms, chambers or any other closed space. They are looking for a license agreement.

The new innovative system consists of a crystal hollow cylinder of 3.2cm of diameter, stuffed with a substance that absorbs CO2. There are two air-impelling systems at its ends with electronic devices that create a flow that goes trough the cylinder. At the entrance of the system there is a water barrier, the function of which is to dehumidify the air that goes through it.

Main Advantages:
- The airflow can be varied modifying the speed of the air impellers so that the CO2 absorption can be faster or slower.
- This new system helps to reduce the concentration of CO2, by means of a chemical system of absorption on a variable airflow.
Innovative Aspects : The water barrier consists of a humidity absorption system that it is linked to an impulsion system in a way that it does not exist any exchange between the air and the atmosphere if the ends of the electro-valves are not open. The volume of the air can be regulated in function of the speed at which it is desired that the reduction of the CO2 concentration take place.

Abstract : COST Action 715 on 'Meteorology applied to urban air pollution problems' was set up to evaluate meteorological variables that are needed in air quality assessments in urban areas. Some of these variables are not routinely measured, and in normal circumstances the number of meteorological stations in urban areas is limited to a few sites. The action was organised in four working groups, dealing with (1)  urban wind fields, (2)  surface energy budget and mixing height, (3)  air pollution episodes in cities, and (4)  meteorological input data for urban site studies.

The project held a workshop in Toulouse, France, on 3 and 4 October 2001, comprising expert presentations on mixing heights and temperature inversions in urban areas. The workshop was jointly organised by working groups 2 and 3. Nine presentations were made, five on mixing heights and four on inversions. This volume contains the extended abstracts, conclusions and recommendations of the workshop.

Abstract : The Institute for Reference Materials and Measurements has characterised and certified a set of six European reference soils, the so-called EUROSOILS, under the number IRMM-443. This unique set of reference soils has been originally designed by the former JRC Environment Institute (now the Institute for Environment and Sustainability - IES) . After a successful validation and trial period it was decided to transfer the project to IRMM in order to produce a new type of certified reference materials.

The report describes the certification of pH in suspensions of pure water and 0.01 M CaCl(2)  as well as of the adsorption coefficients for atrazine, 2,4-D and lindane in these soils. Additionally, indicative values for the pedological parameters C(tot) , C(org)  and N(tot)  are given. The adsorption coefficients were obtained according to the prescriptions made in the OECD Testguideline 106 whereas for the pedological parameters the respective ISO standards were followed.

A high temperature dust filtration system”
Abstract: SWIRLER is an innovative system useful for specific application in the reduction of dusts present in the hot gases produced in municipal incinerators for urban solid waste or for gasifying processes. The particle abatement method is based on the principle of centrifugation of the flow through an axial centrifuge. This system differs from already existing ones in that it operates on fumes still at high temperatures. The advantage is that the most polluting substances are still in a gaseous state and thus, they can be easily separated by means of dynamic effect from other lighter substances present in the fumes. Gas enters the single separator, goes through one of its components called SWIRLER that transforms the flow of gas from axial to helicoidal, thus creating a swirling action which forces the particles which  must be retained against the walls of the tubular duct and concentrating the dust in an external crown. The principle flow of the purified gas is aspired into a central duct, while the secondary flow is conveyed to an external ring which carries it towards the traditional dust demolition device and is finally sent again to the combustion chamber. The purified central flow is then sent again to be converted into an axial flow.
