Waste water is becoming an industrial raw material

By 2025, one third of the world‘s population will be affected by water shortages and by 2050, 60 percent. There will be a 40% increase in water consumption by 2025. Water is used in steel industries up to eight times

June 2005: Prohibition on dumping untreated municipal solid waste

The dumping of municipal solid waste is scheduled to cease completely by 2020. The storage of non-pretreated municipal solid waste has already been prohibited since June 1, 2005. This has meant, for example, that the paper industry can no longer dump its residual materials.

Best available techniques (BAT) are mandatory under the Directive for authorizing installations

According to the IPPC Directive, industrial installations that are particularly relevant to the environment must be authorized on the basis of the best available techniques (BAT).Older (existing) installations must be run in compliance with BAT by October 30, 2007.

Megatrends are driving the transformation in production and are demanding new approaches to solutions

Megatrends

Urbanization

Consequences Measures

Increasing number of environmental laws to protect human beings, to conserve nature and preserve resources.Ecobalance and Lifecycle considerations are more and more factors for expenses, products and production

Increasing need for environmental protection

Increased competition about resources

Water: Consumption in agriculture will increase to up over 80 % of the worldwide resources until 2020.Global production and availability of resources make competition fiercer at industry sites everywhere.

Demographicchange

Development of new production processes

Energy efficiency - use of regenerative energy

Stricter conditions foroperation and production

Strengthening of the cost position

Innovative Technology for sustained energy use

Pressure 34 bar

Pressure 22 bar

Thermal efficiency rate approx. 10% *

Thermal efficiency rate approx. 14% *

More efficient arrangement of heat exchangers. Higher temperature difference in cycle.

The thermal efficiency rate of the Siemens cycle is higher than the Kalina Cycle KCS 34.

The use of a mixture of ammonia and water as working fluid represents the most efficient type of heat transmission. Instead of the conventional water-steam cycle, this mixture already vaporizes at considerably lower temperatures.

The pressure in the Siemens cycle is lower than in the Kalina cycle. Therefore the plant design is less complex.
