    摘要： he gas and water content of crude oil flowing through a pipeline (1) is measured using a flow restriction (2) in the pipeline, a radioactive source (3) for providing separate radiation energies for each component to be measured, a detector (5) for detecting the radiation transmitted by the various components to generate a first set of signals, pressure gauges (8, 9) upstream of and in the flow restriction (2) for providing a second set of signals, and a signal processor (7) for correlating the signals to provide mass flowrate values indicative of the relative proportions of the components of the mixture. The temperature of the mixture in the flow restriction can also be measured (12) and fed to the signal processor (7) for ensuring that accurate values of flowrate are obtained when temperatures vary.

    摘要： A process for hydrocracking a heavy hydrocarbon oil feedstock, a substantial portion of which boils above 524 °C, is described which includes the steps of: (a) passing a slurry feed of a mixture of heavy hydrocarbon oil feedstock and from about 0.01-4.0 % by weight (based on fresh feedstock) of coke-inhibiting additive particles upwardly through a confined vertical hydrocracking zone, the hydrocracking zone being maintained at a temperature between about 350° and 600 °C a pressure of at least 3.5 MPa and a space velocity of up to 4 volumes of hydrocarbon oil per hour per volume of hydrocracking zone capacity; (b) removing from the top of the hydrocracking zone a mixed effluent containing a gaseous phase comprising hydrogen and vaporous hydrocarbons and a liquid phase comprising heavy hydrocarbons; (c) passing the mixed effluent into a hot separator vessel; (d) withdrawing from the top of the separator a gaseous stream comprising hydrogen and vaporous hydrocarbons; (e) withdrawing from the bottom of the separator a liquid stream comprising heavy hydrocarbons and particles of the coke-inhibiting additive; and (f) fractionating the separated liquid stream to obtain a heavy hydrocarbon stream which boils above 450 °C said heavy hydrocarbon stream containing said additive particles, and a light oil product. According to the novel feature, at least part of the fractionated heavy hydrocarbon stream boiling above 450 °C is recycled to form part of the heavy hydrocarbon oil feedstock at a lower polarity aromatic oil is added to the heavy hydrocarbon oil feedstock such that a high ratio of lower polarity aromatics to asphaltenes is maintained during hydroprocessing. This provides excellent yields without coke formation.
