摘要： Method of producing ethylene and, optionally, propylene by subjecting a feedstock to steam cracking to produce a first olefin containing stream; heating an ethanol containing stream with heat from a steam cracker; passing the heated ethanol containing stream over a dehydration catalyst at a temperature between 200 C to 500 C preferably 250 C to 450 C to produce a second olefin containing stream; and combining the first and second olefin containing streams to give an initial product stream containing ethylene and optionally propylene. The initial product stream is subjected to purification including at least i) water content reduction ii) hydrogen content reduction iii) reduction of content of molecules containing 4 or more carbon atoms and iv) ethane content reduction.

摘要： A calculated vertical velocity sensor signal is determined from a recorded pressure sensor signal. A constructed vertical velocity sensor signal is determined as a linear combination of the calculated vertical velocity sensor signal and a recorded vertical velocity sensor signal in dual-sensor seismic streamer data, using a mixture coefficient as a proportionality constant. An upgoing pressure wavefield component is determined as one half of a difference of the recorded pressure sensor signal and the constructed vertical velocity sensor signal, as a function of the mixture coefficient. An error in the upgoing pressure wavefield component is determined by propagating errors in the recorded pressure sensor signal and constructed vertical velocity sensor signal terms. A value of the mixture coefficient is determined that minimizes the error in the upgoing pressure wavefield component.
