MEDC basically means the country have education, good water supply,health care and high transportation. While LEDC means the county are very less education, but it doesnt mean they have no education. It means they have but less.
Ethane (/ËÉÎ¸eÉªn/ or /ËiËÎ¸eÉªn/) is an organic chemical compound with chemical formula C 2 H 6. At standard temperature and pressure, ethane is a colorless, odorless gas.Ethane is isolated on an industrial scale from natural gas, and as a byproduct of petroleum refining.Its chief use is as petrochemical feedstock for ethylene production.lthough ethane is a greenhouse gas, it is much less abundant than methane and also less efficient relative to mass. It has also been detected as a trace component in the atmospheres of all four giant planets, and in the atmosphere of Saturn 's moon Titan.
Recall from Part III that ethane has about 66,500 BTU/gallon. If we multiply by 42 to get BTU/Bbl, that yields the BTU factor in the above table. (2,790,000 BTU/Barrel or 2.79). If we divide the price of ethane on a per barrel basis by the BTU factor, weâll get the price of ethane on an MMBTU basis.(0.46 * 42) / 2.79 = $6.92/MMbtu. Obviously thatâs a lot higher than the price of natural gas at $2.00 /MMbtu. But that number pales against natural gasoline.f we multiply by 42 to get BTU/Bbl, that yields the BTU factor in the above table. (2,790,000 BTU/Barrel or 2.79).
