Carbon Dioxide Separation from Flue Gases: A Technological

CO 2 is the primary anthropogenic greenhouse gas, accounting for 77% of the human contribution to the greenhouse effect in recent decade (26 to 30 percent of all CO 2 emissions). Main anthropogenic emissions of CO 2 come from the combustion of fossil fuels. CO 2 concentration in flue gases depends on the fuel such as coal (12–15 mol-% CO 2) and natural gas (3-4 mol-% CO 2).

Fossil fuel power station - Wikipedia

A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity.Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator.The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine.

Water Handbook - Preboiler & Industrial Boiler Corrosion

In these applications, the increased dissolved solids contributed by sodium sulfate (the product of the sodium sulfite-oxygen reaction) can become a significant problem. Also, sulfite decomposes in high-pressure boilers to form sulfur dioxide (SO 2) and hydrogen sulfide (H 2 S). Both of these gases can cause corrosion in the return condensate

Selective Catalytic Reduction - an overview

In the exterior of the ECA, i.e., when high-sulfur fuel is used, the exhaust gas should flow out without making contact with the SCR catalyst. Fig. 4.1.2 shows a schematic of the SCR system in (A) vertical and (B) horizontal installations.

2020 Toyota North American Environmental Report

"Carbon" is one of Toyota's four focus areas in North America. Our carbon strategy addresses Challenges 1, 2 and 3 of the Toyota Environmental Challenge 2050 through reducing CO 2 emissions from new vehicles, helping suppliers and dealers eliminate their CO 2 emissions, and eliminating CO 2 emissions from our operations. Climate change affects people in all parts of the global community.

Hydrogen economy - Wikipedia

In the current hydrocarbon economy, heating is fueled primarily by natural gas and transportation by petroleum.Burning of hydrocarbon fuels emits carbon dioxide and other pollutants. The demand for energy is increasing, particularly in China, India, and other developing countries.Hydrogen can be an environmentally cleaner source of energy to end-users, without release of pollutants such as

Selective Catalytic Reduction

When the flue gas contains sulfur, as is the case with diesel exhaust, SO 2 can be oxidized to SO 3 with the following formation of H 2 SO 4 upon reaction with H 2 O. These reactions are the same as those occurring in the diesel oxidation catalyst.

IMO 2020 – cutting sulphur oxide emissions

Some ships limit the air pollutants by installing exhaust gas cleaning systems, also known as "scrubbers". This is accepted by flag States as an alternative means to meet the sulphur limit requirement. These scrubbers are designed to remove sulphur oxides from the ship's engine and boiler exhaust gases.
