Simple, Low-cost Carbon Filter Removes 90 Percent Of Carbon Dioxide From Smokestack Gases
ScienceDaily ^ | (May 20, 2008) | staff

Posted on 05/21/2008 5:37:59 AM PDT by saganite

Researchers in Wyoming report development of a low-cost carbon filter that can remove 90 percent of carbon dioxide gas from the smokestacks of electric power plants that burn coal and other fossil fuels.

Maciej Radosz and colleagues at Wyoming's Soft Materials Laboratory cite the pressing need for simple, inexpensive new technologies to remove carbon dioxide from smokestack gases. Coal-burning electric power plants are major sources of the greenhouse gas, and control measures may be required in the future.

The study describes a new carbon dioxide-capture process, called a Carbon Filter Process, designed to meet the need. It uses a simple, low-cost filter filled with porous carbonaceous sorbent that works at low pressures. Modeling data and laboratory tests suggest that the device works better than existing technologies at a fraction of their cost.

Oops.

> the plant would require 9200 tons of coal

Little typo on my calculator there. 9900 tons of coal is the correct number, with corresponding increases in the amount of oil extracted as well.

Two year payback time is more than acceptable!

Seriously...has anyone picked up on just what level of CO2 would be acceptable?

My understanding is that if it fell below 200 ppm, most vegitation would die.

But remember,
even if the replacement filter material were free,
and even if there were no cost to create and install the filters,
and even if there were no smokestack “excessive backpressure (lower efficiency to generate electricity!), and even if there were no storage disposal volume, energy, manpower, or transportation costs (or pipe line fees or pipe construction costs),
and even if there were no use for the CO2 that is now being released (because we ARE seeing 25% MORE plant and crop growth from the increase in CO2 ...)

There would still be NO reason to trap or separate the smokestack CO2.

AGW is socialist myth.

Roger your point, but I disagree, on a technicality.

IF (big if) ONLY free market forces were driving reduction in CO2 (for whatever reason), THEN there would be a reason to do it.

I totally agree that the Global Warmism religion is bogus.

Now we can build more coal-burning power plants.

The US has plenty of coal.

Wow, now all we have to do is burn the saturated filter in the same boiler as the one from which it came, right?

Sorry, but I’m way more worried about sulfer and mercury emissions than I am plant food coming out the end of a pipe.

And so should you be more worried since those are real problems and CO2 isn’t but since the Supreme Court said CO2 should be considered a green house gas and regulated as such that makes it a problem the coal burning power plants need to deal with. If 90% of those CO2 emissions can be dealt with in a cost effective manner then maybe we can continue to build them.

My first question was... "What happens to the captured CO2?"

That was my first response too. Great answer.

This is remarkably good news. Carbon capture and sequestration at the source is identified as one of the 12 wedges that can be used to reduce civilizations carbon emissions.

Introduction to the Wedges

Wedge Summary Table

Capture CO2 at baseload power plant (PDF)

The main unknown is the total sequestration capacity -- there's a wide range of estimates. But if this is truly commercially viable, this is an important advance.

Unfortunately, not in the USA. I understand China is trying this.

Adding Karrick pre-processing to a coal-powered electrical power plant would increase the plant’s CO2 emissions by about 10% to 15%. To many so-called Greens, this would be a crime against humanity.

The GW cultists are trying to kill every coal plant under construction in the US. So far they are pretty successful. This is the major risk in building these add-ons. You can invest $500 million, get 70% of the construction complete, and then environmental lawsuits can shut you down. Industry is also afraid that the new administration in 2009 will enact carbon taxes or CO2 caps.

China is deploying about two coal powerplants per week.

Carbon sequestration is going nowhere. It is horribly expensive. Even greenpeace is against it.

Thanks for the ping. Goes to show that private research works.

Sweet...

I wonder if they could sequester the CO2 and use it in "enhanced greenhouses" e.g. for plant growth. You know, like corn.

Cheers!
