specific gravity for common natural gas : 0.55 to 0.7
Specific gravity is unitless and is give the density of the gas divided by the density of air at 20C and 1bar.
2. Natural gas is colorless, tasteless, AND IS ODORLESS IF IT IS NATURAL, requiring the addition of an odorant [one or more of several "Mercaptans"] to allow olfactory detection [smell] of leaks.
3. When gas from an underground leak travels great distances [underground], the odorant can be "scrubbed out" of the gas, thereby rendering it again ODORLESS, and therefore a severe explosion and fire hazard.
4. Being a fossil fuel, it is carbon based, and its byproducts of combustion include carbon compounds [such as carbon dioxide and/or monoxide] which contribute to the environmentally damaging "greenhouse effect."A:
One disadvantage is that burning it creates CO2 emissions (although not as much as oil or coal), and CO2 is a greenhouse gas. Natural gas itself is actually a very strong greenhouse gas also (much more than CO2 in fact). Another disadvantage is that it can leak and cause fires and/or explosions.A:As noted above, Natural Gas is a fossil fuel. I am skeptical of calculations that it produces less carbon dioxide than other fossil fuels, although it does burn cleanly and efficiently.
In some places, Natural Gas is considered a waste gas, and excess methane is just burnt in the atmosphere without using any of the energy it carries. For efficiency, we should be utilizing all of our fossil fuel hydrocarbons.
Some communities are now investing in recovering natural gas from garbage dumps and farming for energy production. There is more of this that we could be doing.
As far as fueling automobiles with either Compressed Natural Gas (CNG) or Liquid Natural Gas (LNG), the refueling process is slow (slower than using propane), and high pressures are required. And there are dangers of carrying around CNG or LNG tanks in vehicles.A:If we are to believe scientists concerning global warming, we need to look at the two products here. Natural gas is mostly methane (as previously pointed out). Natural gas also escapes into our air naturally. Methane is many times more of a forcing agent in terms of green house effect. Converting methane into Carbon dioxide (a less substantial green house gas) would reduce our overall forcing in terms of real forcing.
There are several advantages to using compressed natural gas (CNG) to power vehicles. First, it is the cleanest burning fuel available. This reduces harmful emissions, which helps air quality. Secondly, there is an abundance of natural gas right below our feet. Increasing the production of natural gas would make the US less reliant on foreign sources for its energy, which would also help its national security. Third, as a result of the abundance of natural gas, it is much cheaper than diesel or gasoline. There are many areas throughout the US where natural gas is close to or less than $2 per gallon.
A: The gas orduces lots of energy and is easy to transport using pipelines.
D: It produces more pollution than oil and if it leaks natural gas can cause a big explosion and/or fire
Advantages of natural gas:
- It is a very clean burning fuel
- There is an abundance of it throughout the world - the U.S. has the 6th largest reserve of natural gas in the world
- It is about half the price of gasoline
- It can be used in vehicles and is very efficient
- It is used to heat most homes
- It is easy to recover it from shale
Disadvantages of natural gas:
- There are only about 1,000 fueling stations across the U.S. open to the public
- There aren't very many cars that use it yet
One advantage of natural gas is its abundance in the U.S. Our country has the 6th largest natural gas reserve in the world. Natural gas also has the advantage of being the cleanest burning fuel available.
it can help keep other gases from the destroying the atmosphere(good for the enviornment)
and it also made vampires decay in the caves back then so there arent any more alive...(or are there?)
Also natural gas is used for fuel... and other things that have to use power
Natural gas is a carbon fuel so burning it generates the greenhouse gas carbon dioxide. However this produces less carbon dioxide than the same amount of energy from burning oil or coal, so natural gas is slightly cleaner than other fossil fuels.
1 Therm is 100,000 BTU, and as there are 1000 BTU in 1 cubic foot of gas, 1 Therm = 100 cubic feet. Density of methane = 0.72 kg/cubic meter which is 35.3 cubic feet, so 100 cubic feet = 2.04 kg
Biogas is methane collected in a power plant from decomposing animal manure and organic matter, which is sometimes grown specially for this purpose.
To mention but few;
Natural gas does not have many carbon atoms in its chain, so there is more than enough oxygen in the surrounding air to burn it. When compared to a long chain hydrocarbon like diesel, which will never burn completely with the normal amounts of oxygen in the air mixture surrounding it, natural gas can be identified as easily flammable as it does not give out a lot of smoke due to incomplete combustion.
There are three possible answers to this question:
1. We will have to wait until scientists create a new type of fuel other than fossil fuel.
2. We may never be able to drive again
3. Nothing as scientists may have created a new fuel
Yes dehydration of neutral gas is using triethlene glycol (TEG) because TEG is the best water vapor absorbent.
Natural gas + Oxygen -> Carbon dioxide + Water
eg: CH4 + 2O2 -> CO2 + 2H2O
Where complete combustion of methane (CH4, a natural gas) is achieved.
After stating what precisely is meant by 'natural gas' (could be methane o.s.e.) then, in words, it could be something like:
"One mole of the natural gas 'methane' reacts with two moles of oxygen to form one mole of carbon dioxide and two moles of water"
Well, a simple chemical notation is easier and less ambiguous!
cause electricity stimulates the molecules in the gas, and since igniting is the only mayor funccion a flammable gas can do, it ignites.
Natural gas, methane, the fossil fuel, is NOT a renewable resource.
Natural gas, methane, produced from pig manure and rotting vegetation and collected from landfills IS a renewable resource.
It cannot be renewed from its original source as fossil fuel. Much of the natural gas we are burning now formed in deposits buried during the Devonian period, 300 million years ago. It is possible natural gas could form in as little as 50 million years.
None of the fossil fuels are considered to be renewable in that sense. But, since natural gas is primarily methane, and methane is readily available and obtainable from renewable sources other than gas wells drilled into conventional underground reservoirs, it can be considered renewable.
Methane can be derived from organic matter undergoing decomposition. For example in many parts of India, methane is generated through decomposition of both human and livestock feces, gathered and used as cooking gas. Methane can be recovered from organic matter decomposing in land fills and through processing of animal waste. .
switch the jets over to natural gas. get them at most hardware stores.
In addition to having the water chemically tested - the easiest way would be turn on a spigot (preferably an outside one) and then hold a lighted match near it. If a flame lights where the water spout is, that's pretty good proof.
An electric heat pump needs heat available to pump. If it is 30 degrees outside, heating a spa to 102 or so, may be impossible unless the heater has some type of alternative heat source. A properly sized, gas fired heater can take care of a larger range of heating needs. A combination heat pump and natural gas heater, probably with a controller, really makes the issue more difficult, expensive, and would require a lot of study for efficient, cost effective operation. Bottom line: In really mild climates a heat pump might do the job. In cooler climates the gas heater rules. And where a wide range of temperatures and high heat demand is wanted by the customer, a gas heater is the only way to go. A backup heat pump may take years to payout. HM Louisiana
It is easiest if the gas line and the electrical outlet are already set up in your home. At that point, it is easy to set up the appliance.
When hooking up a new or used gas appliance it is required that you use a new gas line. I always try to use a flexible line and make sure it is extra long so the appliance can be moved in and out. Shut the gas off at the valve and remove old gas line and replace with a new one. They do have different sizes, so you can take the old one to your nearest home depot type store to ensure the correct size. They also have the needed fittings to do most jobs,always use thread compound on the joints and check for gas leaks when done with soapy water..Good Luck.
Consult with a legally licensed gas fitter/plumber. If you do it and something goes awry you will not be covered by your home insurance and you really don't want it to happen now do you. Best it be legal and done rite...
Basically, it is extremely difficult to get solids to burn. It is even somewhat difficult to get liquids to burn! Gasses burn. Heat turns liquids or solids to gasses and then they burn. In a car engine, fuel injectors turn the gasoline into a fine spray which quickly evaporates into a gas. It then burns.
Coal does not burn. A fire heats coal. Then coal gives off gasses. The gasses burn. Then the coal gets hotter. As the coal gets hotter, some of the carbon in the coal turns to gaseous carbon, some of the carbon does not, those flakes of carbon become soot. The carbon gas burns. Some stuff simply is left.
It gets its gas from being pressed under the ground for thousands of years and gets burned into gasoline.
To understand the issue more fully you need to understand 'Peak Oil', the point when oil production reaches its maximum and after which it goes into irreversible decline. Although this is roughly halfway through all reserves, after this point oil becomes increasingly expensive and difficult to extract. Since demand for oil will outstrip supply the price will drastically increase after the peak and have huge effects on oil dependent industries: transport, agriculture, manufacturing, the military, medicine and many more.
Many people think the Peak is imminent (within 10 years) or has already happened. Coal reserves can be expected to peak later, in the next 20 - 50 years, but as the world's population keeps growing and consumption of fossil fuels increases (despite the known effects to the climate), it is difficult to predict. Of crucial importance is the fact that the development of alternative, renewable energy sources (wind, solar, nuclear fusion) are reliant on oil use.A:
Oil in about 50 years. Natural gas in about 70 yrs and coal in about 250 yrs.A:At current consumption and the population growth, scientists have determined that the oil supplies will run out in 500 years. A:Our coal will run out in about 40-50 years at the rate we are going at, according to scientists. If we use less coal and more renewable sources, it is sure it will last much longer, but the high demand for coal in industry is always rising as our world modernizes. A:it takes 500-1000 years A:pessimistically 30-40 years, optimistically ~100
Get real people. We have only been using oil for a little over a hundred years in any real capacity. If we have already reached peak production, and usage is increasing every day, than we are in trouble. Cant be too many years left!
Not unless ther is something seriously wrong with it.
1. Associated gas in Petroleum wells is utilised.
2. Tripura state, which is an extension of big gas fields of Bangladesh
3. Krishna-Godavari fields - These offshore sites spread along the mouths of River Godavari are the biggest find with great potential
There is a conversion kit that you can buy at the hardware store. It is fairly simple to do.
Typically it involves switching out orifices, which look like a short bolt with a hole in the middle. Take out the old, put in the new.Answer 2I don't understand what you mean by "stove." If you refer to a space heater with ONE BURNER AND ONE CONTROL VALVE, then you only have to change ONE ORIFICE. BUT, if your are refering to a kitchen range or cookstove, then you will have to replace the orifice IN EACH BURNER, INCLUDING THE OVEN(S).
To make the conversion, you must install the proper sized orifice for the gas you will be using in the heater or stove. For the sake of simplicity, the following directions are for a single burner space heater. For a multi-burner heater, or a cook stove, make the change at each burner. To change an orifice:
1. Turn off the gas supply STOP valve [valve at the wall, to which the flexible metal gas line ("hose") is attached].
2. Disconnect the flexible gas line from heater inlet [usually on the ON-OFF control valve on the heater].
3. With an adjustable wrench, or an open end wrench, remove [counterclockwise] the heater's control valve. Located on the end opposite from where the gas line was attached, is the orifice [it looks like a brass pipe plug (hex head) with a small hole in the center of the hex head]. It is the size of this hole which determines the rate of gas flow.
4. Two wrenches will be required for this step. Using one wrench on the hex head of the orifice, and another wrench on the hex shoulder of the control valve, unscrew [counterclockwise] and remove the orifice from the valve. I recommend that ANY time you disassemble threaded devices, that you use a wire brush to CLEAN ALL THREADS, which will make reassembly easier.
5. Although not required by Code, apply three or four turns of TEFLON thread seal tape to the "NEW" orifice threads.
6. Carefully by hand, so as NOT to crossthread, screw the new orifice into the valve body as far as possible.
7. Again using two wrenches, tighten the orifice into the valve body, clean the threads of the valve body, and apply a few turns of Teflon tape to those threads.
8. Fully hand thread the valve body back into the cast iron burner, and tighten with a wrench being careful, near the end, to stop when the control valve hand lever is on top.
9. Clean the hose coupling nipple threads on the valve and reconnect the metal "hose" [NO tape is required on these coupling threads].
10. Prepare a "test" solution of a few drops of liquid dishwashing detergent in about half a cup of water. With a paintbrush, whip solution into a bubbly "froth."
11. Turn gas ON at the wall stop, and OFF at the heater control valve, and "paint" the soap froth onto all joints.
12. Watch for new/"growing" bubbles for a few minutes. If bubbles form, you have a leak, and must retighten the joint, or install Teflon tape. If there is NO CHANGE in the bubble layer, the joints are tight and the heater is ready to use.
Most new stoves have both orifices in the control valve. It is a matter of making sure you have the correct one in place. The gases have a different density which results in a different mass of gas being supplied to the burners.
Natural gas is ignited and the heat is used to boild water and generate steam. Steam is then forced through impeller turbines spinning them in turn spinning Generator Coils that Produce the electricity.
Each ton of Urea will need 930 cubic meter of natural gas. It will require 230 cubic meter for conversion and nearly 700 cubic meter for input chemical. In MMBTU terms, it will require nearly 27 MMBTU. In calorific value, it will require 7 Giga calories.
