Question

Urgent, please can anyone tell me the quantity of C02 that will be produced for using 500m3 of natural gas?

Answer 1

natural gas is mostly made up of methane (70-90%) just to simplifie things ill assume that its 100% methane.

methane has a density of 0.668kg/m^3 [1] so for the 500m3 you will get 334 KG of methane [2].

is mad up of 1 part carbon and 4 parts hydrogen. the atomic weight of carbon is 12.0107 g·mol−1 and hydrogen 1.00794 g·mol−1.

so by weight the methane will be made up of by weight  12.0107 : 4.03176. = 2.97902 : 1. which means for every 3.97 KG you will get 1KG of carbon

co2 weighs 44.0095 g/mol . oxygen has a atomic weight of 16. so by mass it will be made up of 44  : 32= 1: 0.72 which means that for every KG of carbon you will get 1.72 KGs of CO2.

so to get your answer you just times how much (in kg) methane you have by 1/3.97 and 1.72.

334 * 1/3.97 *1.72 = 144.70528

so you will get 144KG of co2 if you burn 500 m3 of natural gas

------------------

note natural gas is a gas so its density is related it its pressure. this is only valid at one atmosphere.

edit evins.

its a gas, a gas has no fixed density.

Answer 2

gengi has the correct method.

Answer 3

1 billion Btu's of nat gas produces 117,000lb CO2.

http://www.naturalgas.org/environment/na...

Natural gas produces 1,000Btu/cubic foot.

http://hypertextbook.com/facts/2002/Jany...

1 cubic foot (1 ft³)= 0.028 316 846 592 m³ (exactly)

http://en.wikipedia.org/wiki/Cubic_metre

Sooooo.....

(500m3) multiplied by

(1ft3/.028316846592m3) multiplied by

(1,000Btu/1ft3) multiplied by

(117,000lb/1,000,000,000Btu) equals

Approximately 2,065.9lbs of CO2

or 6.5 times the "simple" answer given earlier.

I'd probably just say "It produces a ton of CO2!" and call it good (that's in US short tons or 2,000 pound increments).

Edit:  Apparently, according to another answer, the correct method is to assume 10-30% of a substance is an entirely different substance for simplicity's sake, then assume laboratory settings at exactly 1 atmosphere for simplicity's sake, then....no wonder today's "scientists" believe CO2 is causing global warming!  You can only guess what substances they're assuming is CO2 for simplicity's sake!

Edit Gingy:  Nice try.  It's a commodity bottled and sold by volume in controlled environments at a preset pressure.  Industry standards and international regulations dictate the allowed variance from these figures.  You can't just ignore the unknown quantities and expect your calculations to resemble real world results!  What I present are the real world figures, with links.

Answer 4

I have a HUUUUGE list available at www agua-luna com it's like 33 pages long and would just spam this whole answer. But here's a few cut from the list below. if you'd like the entire list feel free to visit www agua-luna com or email me through the site directly and I’ll send you a copy.

Also Agua-Luna com now offers Carbon Offsetting Credits, since our Team of Volunteers is already accomplishing several carbon eliminating projects, we’re now converting the carbon offsets to you. Visit www agua-luna com for a FREE carbon calculator to calculate your carbon footprint for free and more info on carbon credits.

You could also Volunteer with us, planting a tree or working on a Sustainable Renewable Energy Building Project in Mexico with us. Again see www agua-luna com for more info.

I also do some free consulting, there's more info on the site about that too. Here’s some more ways to help the environment…

Recycle paper, cardboard, newsprint and magazines.

Recycle aluminum cans.

Recycle all batteries.

Recycle and reuse. Roughly 50% of the average person's trash can be recycled. Don't forget that hazardous waste like batteries, your printer's ink cartridges, and cell phones can be recycled too! Find out how and where to recycle in your area. Always buy recycled paper. Just 1 ton of recycled paper saves 17 trees.

Just because your community doesn't pick up all recyclables on the curb, it doesn't mean there are not viable alternatives nearby. Check with dry cleaners, supermarkets, manufacturers, your local public works department and civic organizations to find out where recycled goods can be dropped off, at a location near you.

Did you know that just in 1995 alone, recycled toner cartridges kept over 21,000 tons of trash out of landfills? Believe it or not, now you can recycle your printer's toner cartridges! Every year, Americans throw out enough printer cartridges to stretch from Los Angeles to New York City and back again. Toner cartridges can be recycled, having just as good a performance as an unrecycled cartridge. To recycle your toner cartridges, find a local business that does printer cartridge recycling, or contact the manufacturer of your current toner cartridge and ask about a cartridge recycling program.

Not only should you recycle, but buy products that are recycled. By purchasing these products, you are helping to conserve natural resources, and to protect the environment.

Wash clothes in cold water.

Hot water is unnecessary for most clothes. When needed, use warm water.

Fill your toilet tank.

Put a plastic bottle or two, filled with water and rocks, in your tank to reduce the amount of water used in each flush.

Clean your filters.

Clean the filters of your air-conditioners once a month to improve energy efficiency. While you’re at it, change your car’s filters as recommended in your manual.

Get a low-flow shower head.

Stop at the hardware store on your way home, and get a low-flow shower head. Takes a few minutes to install, and it’ll save gallons of water a day.

Lower your thermostats.

If you use heating, get by with less heat and wear warmer clothes. If you use air-conditioning, get by with less cooling and wear cooler clothes.

If it’s a nice sunny day, hanging clothes only takes a few minutes, and you’re using solar power instead of electricity to do the job. It also makes your clothes last longer.

Turn down your water heater.

Most people have their water heater’s thermostat turned up too high, wasting energy. Turn it down to 130 degrees, saving energy but still hot enough to kill bacteria.

Use CFC light bulbs.

If your light bulb burns out, replace it with a Compact Flourescent bulb (those spiral-looking ones). They’re more expensive, but if you just replace them one at a time, it doesn’t cost much, and the energy savings is great. And as they last longer, over the long run, you’ll save money.

Wash and dry only full loads of laundry and dishes.

Follow your community's water use restrictions or guidelines.

Install a low-flow shower head.

If you are not looking to change your car just yet there are a number of ways you can be more environmentally friendly and help you save money by conserving fuel.

Lighten your car to reduce weight by not carrying unnecessary items.

Cut your speed and stick to the speed limits

Drive smoothly avoiding heavy accelerating and braking.

When stationary for a long time, switch off the engine.

Closing windows will make the car more efficient by being more aerodynamic.  Remove roof bars when not is use also helps.

Make sure your tyres are properly inflated as under inflated tyres cause more resistance.

Where possible, walk, cycle or even use public transport.  

If possible lift share to reduce the number of cars on the road.

Try mass transit.

Millions of people use it, and it saves tons of fuel. If you don’t already, give it a try.

Unload your car.

Remove excess weight from your car (such as stuff that might be in the trunk) to reduce the amount of fuel you use.

Walk instead of drive.

You don’t have to do this all the time, but walking the short trip to a store, or to lunch from work, or some other short trip like that, can reduce the amount of fuel you use over the long term, and you shed some fat at the same time. Or at least burn off that morning donut.

Buy a smaller car.

You won’t be able to do this today, probably, but the next time you’re in the market for an automobile, get a smaller and energy-efficient car rather than a big, lumbering one. It’s one of the best things you can do to reduce your fuel consumption.

Inflate your tires.

Many people don’t realize that their tires are under-inflated. Check the recommended pressure for your tires, and fill them up to that pressure. It only takes a few minutes, but it will save you on fuel consumption (a little) and more importantly, make your tires last longer and reduce the rubber that’s worn off your tires.

Get creative with gift-giving. The gift of time, services, or environmentally positive gifts may be more appreciated than disposable goods that are not to the taste or needs of the recipient.

Look into those lifestyle changes you’ve been putting off

Work from home more. Many organisations, when prodded a little, will accept flexible work arrangements where there is no impact to the work that needs to get done.

Use your oven less.

The oven not only uses a lot of energy, it heats up your kitchen, requiring more cooling. Instead, use toaster ovens, crockpots, microwaves, and electric grills when you can. And when you do use your oven, open it less - you lose 25% of the heat every time you open the oven door.

Mend your stuff.

Try not to throw stuff away and buy new stuff if the old stuff can be fixed. Torn clothing? Takes a few minutes to sew up.

Install a water filter.

If you buy a lot of bottled water, use your tap instead. Some places need a filter to make tap water taste drinkable, but they don’t cost much and they can save money, water, and plastic bottles over time.

Unplug appliances.

If you don’t use an appliance several times a day, it’s better to unplug it, as they often use energy even when turned off

Use rechargeable batteries.

Instead of throwing your batteries away all the time, reuse rechargeable batteries. Costs a little more, but cheaper in the long run.

When you’re looking to buy appliances, be sure to research the most energy-efficient ones. They may cost a little more, but they’ll more than make up for that in the long run with lower energy bills.

Buy a smaller home.

The next time you’re home-shopping, instead of buying the McMansion, look for a smaller home that’s big enough to meet your needs comfortably. Reducing the amount of stuff you own is a good way to need less house. It’s cheaper, and requires less energy to heat and cool. And easier to clean at the same time.

Look for energy efficiency.

Use acryllic paint.

Compost.

It’s not hard to set one up (look it up online), and you can save a lot of waste from the landfill and help your garden at the same time

Water grass early in the morning.

Reduces the amount of water you need to keep your grass looking fabulous.

Plant shade trees near your house.

It’ll take awhile before they can make a difference, but shade trees greatly reduce the need to cool a home.

Coat your roof.

This’ll take up an afternoon, but you only have to do it once every few years. And it’ll save you a lot of money and energy in heating and cooling over the long-term, more than making up for the cost of paint.

Avoid fast food.

Instead, eat at home or at a sit-down restaurant. Fast food restaurants are one of the worst polluters of the environment, both in the massive amounts of beef they must raise, in the wasted packaging, and in the energy they use in so many ways. And they’re tremendously unhealthy.

Buy a manual reel mower or electric mower.

If you’re looking for a new lawn mower, and you have a small yard, consider getting a manual one. They’re much advanced from the reel mowers of our grandparents’ generation, much quieter, cheaper, and they save on fuel and pollution. Electric mowers are also quieter and use much less energy.

Clean up.

Hope this helped, feel free to contact me personally if you have any questions if you’d like assistance in making your first self sufficient steps, I’m willing to walk you step by step threw the process. I’ve written several how-to DIY guides available at  www agua-luna com on the subject. I also offer online and on-site workshops, seminars and internships to help others help the environment.
