Zero Emission Power Plants system

Several other countries are also planning to build zero-emission power plants. The GreenGen Project, started in 2005 in China, will employ hydrogen to generate power and will include a C02-sequestering system.

As alluded to in Chapter 8, the ideal biomass feedstock for thermal conversion, whether it be combustion, gasification, or a combination of both, is one that contains low or zero levels of elements such as nitrogen, sulfur, or chlorine, which can form undesirable pollutants and acids that cause corrosion, and no mineral elements that can form inorganic ash and particulates. Ash formation, especially from alkali metals such as potassium and sodium, can lead to fouling of heat exchange surfaces and erosion of turbine blades, in the case of power production systems that use gas turbines, and cause efficiency losses and plant upsets. In addition to undesirable emissions that form acids (SOx), sulfur can...

Integrated waste management and zero emission plants are commonly heard phrases in the chemical corridors of power these days. What goes in must come out, somewhere. Preferably what comes out should be the desired product. Everything else should be considered as undesirable and its formation avoided or be kept in the system. 

In Figure 2 the flow chart of classic fuel burning incinerator combined with plasma vitrification system of all solid residues is presented. The system is self-supplied in the electric power and it employs only single plasma furnace for vitrification of solids. This way every classic waste incineration plant can be converted to zero waste emission system. The excess of energy in the form of electricity or steam can be sold.
