Clean coal technology refers to a gathering of technologies being created in order to reduce the environmental influence of coal energy production and to mitigate global climate change. There are three distinct technological procedures accessible for the aim of capturing carbon as demanded by the clean coal concept:
1. Pre-combustion capture: This includes gasification of a feedstock like coal to generate gas that may be shifted to develop a mixture of carbon dioxide and hydrogen gas, from which the carbon dioxide can be effectively separated and captured, transported, and eventually sequestered.
2. Post-combustion capture: This is the capturing of carbon dioxide from the exhaust gases of combustion methods.
3. Oxy-fuel combustion: The fossil fuels like coal are combusted in a mixture of oxygen and recirculated flue gas, rather than in air that hugely withdraws nitrogen from the flue gas allowing capturing of low-cost and efficient carbon dioxide.
An initial example of a coal-based plant utilizing carbon capturing technology is a Swedish company Vattenfall's Schwarze Pumpe power station situated in Germany.
I think it is C lay eggs but if not sorry
Answer:
A
Explanation:
because it weak and more weaker then the others in the answer
The giraffe is the organism which has systolic pressure among the other options.
The giraffe has one of the highest blood pressures of any mammal. It reaches pressures of up to 280/180 mm Hg, which is twice that found in humans (120/80 mmHg).
In their heads, a giraffe’s blood pressure remains about equal to a human’s. And they maintain that lower pressure in their heads whether they are chomping leaves from the limbs of tall trees or sipping water at ground level.
A giraffe’s large neck veins contain a complex system of valves that stops the blood from flowing backwards and pooling when it dips its head, which can be a full 20 feet differential from upright in a full-grown giraffe.
