How to purify carbon dioxide and produce natural gas

Madras scientist at the Indian Institute of Technology has two solutions to one problem – climate change and energy security.

Want to get a carbon dioxide home from an industrial source? Do you want to produce natural gas – the purest of fossil fuels – from India’s abundant natural gas reserves under its seas?

Rajnish Kumar, a professor in the Department of Chemical Engineering, has completed a project funded by GAIL, which first shows that almost all carbon dioxide can be separated from industrial exhaust gases, especially from coal-fired plants. The next step is to inject carbon dioxide into the gas hydrate zones, and then the carbon dioxide molecules push the occupants to replace them. Methane can be copied.

Hydrates are a mixture of water and gas and are described as “solid ice-like water containing gas molecules in the molecular wells.”

The process of separating cumene carbon dioxide from exhaust gases is simple enough – cool down to 1.5 degrees Celsius and push it to 30 bar and react with water. Carbon dioxide separates and produces carbon dioxide hydrate.

Next, if you dehydrate the room (soon), pure carbon dioxide will be separated from the hydrates.

So far so good but what do you do with carbon dioxide? You need to find a permanent home to protect it from the elements, right?

It suggests that Kummer may be injected into the methane hydrate zone.

India has a staggering 2,000 trillion cubic feet of hydrate. The Kሽṣናa-Godvari basin alone has an area of ​​134 tcft.

For decades, the National Gas Hydrate program has been thinking about how to extract gas from water.

You only need to inject carbon dioxide, and the gas will do the rest. Like any gas station, it emits potentially harmful methane. Carbon dioxide will live there forever.

His project report is currently with GAIL.

A few questions remain to answer. First of all, do you not need energy to bring the exhaust gases to 1.5 degrees Celsius and 30 bar?

Kumer is sure to be economically viable.

Second, you produce natural gas, which is still a fossil. In today’s world, all fossils are enemies of mankind.

The answer to that is: ute-methane is the best of all fossil fuels – it is much better than coal. Carrying and storing carbon dioxide is a costly affair. In a coal-fired power plant, it can take up to 25 percent of the power generated by the plant.

Methane emissions from gas hydrates can pay off. But importantly, the net carbon dioxide emissions will be less than the greenhouse gas emissions.

The most common form of carbon dioxide is carbon dioxide. The problem here is that you have to spend a lot of energy to get the amines back. In contrast, separating carbon dioxide from carbon dioxide is practically cost-effective.
