The demand curves for competitive firms, however, are almost perfectly elastic because no matter how these firms change their production, in a perfectly competitive economy, there are so many firms out there that its production will not affect anything.onopolistic competition, because there are so many relatively weak firms, there are no barriers to entry. Companies can enter the market relatively easily (although, of course, not as perfectly easy as in perfect competition). This makes for a long-term equilibrium competition of no profit.
How Is Natural Gas Produced. Natural gas is found in oil fields, natural-gas fields and coal beds. Since natural gas isn't a pure product, it needs to undergo processing before it can be used as consumer fuel. The gas is extracted from a field using a decompression process called retrograde condensation.
Natural gas is a fossil fuel formed when layers of decomposing plant and animal matter are exposed to intense heat and pressure over thousands of years. The energy that the plants originally obtained from the sun is stored in the form of chemical bonds in natural gas.atural gas can be used to produce hydrogen, with one common method being the hydrogen reformer. Hydrogen has many applications: it is a primary feedstock for the chemical industry, a hydrogenating agent, an important commodity for oil refineries, and the fuel source in hydrogen vehicles.
