The NOx present in the waste gases of both power stations and any other type of fixed source of emission can be eliminated by a series of methods and secondary measures that are based on the reduction of NOx using different reducing agents in the presence or not of a catalyst.
Directive 2001/80/EC of the European Parliament on the limitation of emissions of certain pollutants into the air from large combustion plants (“LCP Directive”) allows Member States to prepare a National Emissions Reduction Plan, NERP-LCP, with which the same reduction is achieved globally by applying the individual limits to power stations and industrial facilities, such as cement plants, waste incineration and other combustion sources.
To help companies comply with the IPPC directive on NOx emissions, Fertiberia has developed a complete range of reducing agents for use in installations with Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR).
There are several technical solutions to achieve the emission reduction targets set by law, with the two main systems being Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR). Both achieve the abatement of NOx gases thanks to the direct application of ammonia or urea at the emission points. Depending on the characteristics of the source of the emissions, the presence of a catalyst (SCR) may be necessary.
We now have NOx gas reduction systems in all our nitric plants and have extensive experience in the supply of reagents to large industrial groups. Some of the main industrial groups that are customers of Fertiberia include Spain’s most important cement, incineration and energy companies.
As in the case of urban wastewater, the purification of liquid effluents is a fundamental part of environmental management in any industry. This must be assumed in its double facet of the environmental obligation to society and as part of the production process.
The nitrogen solutions produced and sold by Fertiberia are widely used in biological purification, as nitrogen, along with phosphorus, plays a very important role as a nutrient in the eutrophication process.
Hydrogen sulphide is a toxic gas with a strong odour that is produced as a result of biological activity in sewage networks and wastewater treatment plants. Apart from its toxic and unpleasant odour, it can also cause corrosion problems in everything that comes into contact with this gas. Applying Calcium Nitrate Solution acts directly on the source of the problem, preventing the formation of hydrogen sulphide, odours and corrosion.
