Abstract: A process of fractionating a stream is disclosed. The process comprises fractionating a reactor effluent stream in a fractionation column. A reboiling stream is taken from a reboil outlet in a side of the fractionation column. The reboiling stream is combined with a stripping vapor stream to provide a mixed reboiling stream. The mixed reboiling stream is heated in a reboiler to vaporize less than 70 vol % of the mixed reboiling stream to produce a reboiled stream. The reboiled stream is charged to the fractionation column through a reboiled inlet in a side of the fractionation column. A stripping vapor stream may be fed to the fractionation column near a bottom stage. An overhead product stream and a bottom product stream is taken from the fractionation column.

Abstract: A powdered adsorbent lossless recovery method based on a belt filter is provided. The lossless recovery method includes a first separation step of collecting a powdered adsorbent at a tail end of a belt filter. In the first separation step, at least a gas-water mixture fluid is used to flush a filter cloth to separate the powdered adsorbent from the filter cloth. In this disclosure, the separation manner of simple water washing used in the conventional technology is replaced with the manner that a gas-water mixture fluid is used to flush a filter cloth. Such a separation manner can not only save a large amount of liquid, but also reduce water content in a flushed powdered adsorbent suspension, so that the leakage of the powdered adsorbent is greatly reduced during transportation, to improve the recovery rate of the powdered adsorbent.
