Global Warming
Global warming facts
The average temperature of the Earth
Has increased between 0.4 and 0.8 degrees over the past 100 years.
Will rise by 5.8 degrees by year 2100.
Drought
- Drought ranks second in terms of national economic crisis related to climate change, with annual losses nearing $9 billion per year in the U.S.
- Drought can seriously impact on drinking water supplies and ecosystems, and even contributes to increased food price, poverty and food famine.
Sea levels
Risen about 7 inches over the last 100 years.
Will rise by 7‐23 inches by the end of this century.
(According to IPCC 2007 report)
The rising sea levels could threaten the lives of people living along the coastal area.
What is Global Warming
Global warming is a gradual increase in the average temperature of the Earth's atmosphere and its oceans.
The main reason is over‐emittance of greenhouse gases into the atmosphere.
These greenhouse gases such as carbon dioxide, methane and nitrous oxide absorb heat that would otherwise escape from earth.
Solution Stop greenhouse gas emission, which is mainly carbon dioxide, to the atmosphere.
Current methods and problems
Amine sweetening stripping column is employed to capture CO2, which uses aqueous solutions of various amines. However, challenges of carbon capture using amines:
- High energy consumption
- Large facilities
- Need high investments
- Periodically, the degraded aminated carrier must be replaced by fresh one
Our solution
We can solve these problems with
gas membrane, which are
highly energy efficient, low maintenance cost with modular structure in a compact system.
