union oil and gas

This is a gaseous mixture of lower hydrocarbons, which covers crude oil in an oil field. Natural gas mainly consists of methane, which burns without smoke, and leaves no ash. It is an ideal fuel and can be used for heating, generating electricity, and also as a raw ma..

It is a mixture of gaseous hydro-carbons. It is found usually along with petroleum deposits. Natural gas consists mainly of 85% methane, 10% of ethane and 3% of propane and butane. It may also contain nitrogen, oxygen, carbon di-oxide and hydrogen sulphide. Its great advantage is that it ..

. These caps allow the lighter vapors to escape up the column while the progressively less volatile and heavier fraction condense and flow into the respective trays (through tray holes and overflow) in the lower section of the tower. They can then be tapped out. The major products obtained from the..

An oil company looked for a feasible area on map for constructing a gas station. The length of the land spotted by them on the map is 9 inches. The scale of the map is 1 inch : 4 ft. What would be the actual length of the land? => 38 ft or 36 ft or 35 ft or 37 ft..

It is produced by incomplete combustion of carbonaceous fossil fuels such as coal, fuel oil, natural gas, wood, etc., due to insufficient supply of oxygen. Soot is the most common particulate injected into the atmosphere through human activit..

The change of state from the gaseous form to the liquid form is called condensation. It is also called liquefaction. A good example of this process is that of water vapour in atmosphere condensing to form rain. By applying pressure to a gas the particles come closer and start condensing t..

Polynuclear aromatic hydrocarbons are a class of compounds found throughout the environment in the air, in the soil and in the water. They are found naturally in crude oil, coal tar, and coal. They are man-made during incomplete combustion of hydrocarbons like coal, oil, ga..

In this process, a mixture of water gas and hydrogen under pressure (5-10 atm) is passed over a cobalt catalyst at 450 - 475 K. The water gas required is obtained by passing steam over red-hot coke. C (red hot) + H 2 O ( g ) CO + H 2 water gas..

a) Metal casting can be tested for cracks by putting them in baths of radioactive salts. The castings are then inspected for radioactivity to find out any penetration of salts into cracks. Absence of salt penetration indicates absence of cracks. b) Radioactive isotopes can be used to detect any le..
