摘要： Processes for the separation of a hydrocarbon-containing feed streams are described herein. The processes generally include cooling the hydrocarbon-containing feed stream using a first absorption refrigeration cycle to form a cooled feed stream, introducing the cooled feed stream into a first distillation zone for subjecting the cooled feed stream to distillation conditions adapted to remove a first bottom stream including co-monomer and a first overhead stream including hydrocarbon diluents, olefin monomer and further components selected from H2, N2, O2, CO, CO2, formaldehyde and combinations thereof, passing the overhead stream from the first distillation zone to a second distillation zone for subjecting the overhead stream to distillation conditions adapted to remove a second bottom stream including substantially olefin-free hydrocarbon diluents, a side stream including hydrocarbon diluent and a second overhead vapor stream including olefin monomer, diluents and further components selected from H2, N2, O2, CO, CO2, formaldehyde and combinations thereof, cooling the second overhead vapor stream using a second absorption refrigeration cycle to form a cooled overhead vapor stream and separating olefin monomer from diluents in the cooled overhead vapor stream.

摘要： A method and apparatus for automatically measuring the acidity of overhead water in an oil refinery, and dispensing a neutralizing agent into the refinery system at a rate responsive to that measurement. A sample of overhead water is collected and passed through a filter and cation exchange resin. The acid concentration of the sample is then automatically measured and a signal generated based on the concentration. The signal goes to a controller which controls the dispensation rate of neutralizing agent into the refinery system, thus reducing the acidity of the overhead water and limiting the corrosive effects of such acidity.

摘要： In a fractional distillation column wherein a split-range controller alternately manipulates a valve for flaring gas to decrease pressure and a valve for importing gas to increase pressure as required to maintain a desired distillation pressure, both flare gas and import gas are minimized by providing a valve position controller that slowly drives both of the control valves manipulated by the split-range controller toward a closed position while maintaining the desired distillation pressure.

摘要： A fractional distillation column operating as gasoline splitter is controlled by measuring the octane number of the column overhead fraction and adjusting the reflux to the column in response to the octane number. The octane measurement is effected by an analyzer comprising a stabilized cool flame generator with servo-positioned flame front which provides a real time output signal indicative of a sample octane number. The output signal is utilized to control reflux to maintain a given octane number in the overhead and to provide a control means for downstream blending of the overhead make.
