    摘要: The present invention relates to a method for cleaning a reactor having a tendency of fouling by deposition of solids, wherein a hot solvent, in which the solids are soluble and which has a temperature of at least about 75° C., is applied to the reactor, the solids being substantially dissolved and the dissolved solids being discharged from the reactor, wherein the method is carried out without opening the reactor to atmosphere.

    摘要: The present invention relates to a method for processing high molecular weight oligomer waste products formed during the production of linear alpha-olefins by oligomerization of ethylene in a reactor in the presence of a solvent and a catalyst, characterized in that the high molecular weight oligomers are separated in a separation unit from a product stream of the reactor comprising the solvent, the catalyst, linear alpha-olefins and high molecular weight oligomers having a solidification temperature in the range of about 60-100° C., then diluted with a dilution medium and heated to about 130° C. to about 200° C., the diluted high molecular weight oligomers are then transferred to a disposal device, wherein at least some of the dilution medium may be recovered and recycled for addition to the dilution medium.
