How is ethane cracked to make ethylene?

ETHANE  ETHYLENE: CRACKING 25. ETHANE MUST BE “CRACKED” TO MAKE ETHYLENE 26. THE CRACKING PROCESS INVOLVES BREAKING UP THE CARBON AND HYDROGEN MOLECULES AND REARRANGING THEM. 27. CRACKING IS ACCOMPLISHED BY HEATING ETHANE TO GREATER THAN 800°C (1500°F) IN THE CRACKER FURNACE. 28.

What happens to ethane gas in high pressure?

Ethane – Thermophysical Properties. However, at low temperature and/or high pressures the gas becomes a liquid or a solid. The ethane phase diagram shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the ethane boiling point with changes in pressure.

What kind of fuel is used in ethane crackers?

How many species are in the ethane cracking process?

For the case of the free radical scheme for ethane cracking, there are 8 species in total. The mass For i =1, 2, 3… number of reactions, and j = 1, 2, 3, … total number of species (excluding steam). species. Free radicals, being of much smaller concentrations than molecular species, are ignored in the following differential equations; [1].
