natural gas is used as feedstock for the primary reformer; and 25 to 35% is used as fuel for the reformer radiant section and for steam pro-duction. As natural gas reserves continue to dwindle, feedstocks based on heavier hydrocarbons and coal gasification processes (3) will undoubtedly be used increasingly in ammonia plants in years to come.

Cracking hydrocarbon feedstock with a heavy ta

Steam cracking is a process for the thermal conversion of hydrocarbon feedstock into ethylene, propylene and other cracked gas products by thermal cracking in the presence of steam. Various types of feedstock are used for steam cracking, such as ethane, propane, butanes, straight-run refinery fractions (naphtha, kerosene, atmospheric gas oil

US Patent for Steam cracking of ethane-rich an

This invention relates to a process for cracking hydrocarbon feedstock comprising a mixture of ethane and propane by (a) subjecting the feedstock to a fractionation process so as to separate the feedstock into an ethane rich stream and a propane rich stream, (b) steam cracking each of these streams separately under optimum cracking conditions for each stream in separate furnaces, (c
