摘要： A process for cracking a hydrocarbon stream by: combusting fuel in a gas turbine in the presence of compressed air to produce a flue gas, wherein the flue gas drives a turbine to produce electricity in a coupled generator or work to power a coupled rotating equipment; (a) feeding a first portion of the flue gas to a heat exchanger; (b) feeding ambient air to the heat exchanger to be heated by the first portion of the flue gas to provide heated air; (c) feeding a furnace with fuel and a mixture of a second portion of the flue gas and the heated air obtained by step (c) and (d) cracking the hydrocarbon stream in the furnace.

摘要： A method for heating one or more streams from a refinery process, chosen from the group of a crude tower inlet, vacuum tower inlet, catalytic reformer inlet, coker inlet, thermal cracker inlet and hydrocracker inlet. The method includes transferring, in a heat exchanger, heat from one or more streams from a petro-chemistry process, chosen from the group of a steam cracker charge gas, propane dehydrogenation charge gas and butane dehydrogenation charge gas to said one or more streams from a refinery process for obtaining one or more heated streams in which the temperature of said one or more streams from petro-chemistry process is above the temperature of said one or more streams from a refinery process before said step of heat exchanging has taken place.

摘要： A refrigeration system for cooling a charge gas by a binary refrigerant. The refrigeration system comprises n heat exchangers, n compressor stages, at least one separator and a demethanizer. By flowing depressurized refrigerant through all the subsequent heat exchangers and installing interstage coolers, the overall energy for the refrigeration system is reduced.

摘要： Steam reforming system having a steam cracker and a steam reformer. The steam cracker includes a steam cracking unit to steam crack a feed stream to produce a stream comprising hydrogen, methane and C2+ hydrocarbons; a heat exchanger for cooling the steam cracking product stream; a separation unit for separating the cooled steam cracking product stream into a gas stream including hydrogen and methane and a liquid stream including methane and C2+ hydrocarbons, a demethanizer which is fed the liquid stream producing a third stream containing at least 95% methane and a fourth stream comprising C2+ hydrocarbons. The steam reformer includes a feed preheater which is fed the third stream and steam to provide a preheated stream and a steam reforming unit arranged for heating the preheated stream to at least 800° C. to steam reforming the heated stream and obtain a product stream containing hydrogen and CO2.
