    摘要: A process for polymerizing or oligomerising a hydrocarbon includes feeding at a low level a liquid hydrocarbon reactant into a bulk liquid phase comprising polymeric or oligomeric product admixed with a catalyst. The liquid hydrocarbon reactant is allowed to vapourise to form bubbles rising through the bulk liquid phase and to polymerise or oligomerise to form the polymeric or oligomeric product, with the rising bubbles creating turbulence in the bulk liquid phase, thereby mixing the bulk liquid phase. Gaseous components comprising any unreacted vapourised hydrocarbon reactant and any gaseous product that may have formed are withdrawn from a head space above the bulk liquid phase. Liquid phase from the bulk liquid phase is withdrawn to maintain the bulk liquid phase at a desired level.

    摘要: This invention relates to a process for the production of a mixture of detergent-range alcohols having an average of between 8 and 20 carbon atoms per molecule. The process includes the steps of providing a hydrocarbon stream containing olefins and paraffins in which more than 5% by volume of olefin molecules in the hydrocarbon stream have a total number of carbon atoms which is different from the total number of carbon atoms of the most abundant two carbon numbers of olefins in the hydrocarbon stream; reacting the hydrocarbon stream with CO and an alcohol in the presence of a catalyst in a hydroesterification reaction to form a hydrocarbon stream containing esters and paraffins; separating esters from the hydrocarbon stream containing esters and paraffins; and subjecting the esters to a hydrogenation reaction to provide the mixed alcohol product.

    摘要: A method of cleaning fouled process equipment which includes a process vessel (10) fouled by an organic foulant, includes spraying a hydrocarbon stream at a pressure of at least 69 bar(g) at fouled surfaces inside the process vessel (10) thereby to dislodge the organic foulant from the fouled surfaces. The hydrocarbon stream is sprayed from at least one nozzle (24) located inside the process vessel (10). The hydrocarbon stream is at a temperature below the melting point of the organic foulant or below the melting point of a major component of the organic foulant when the organic foulant is a multi-component organic foulant. The dislodged foulant is removed from the process vessel (10).

    摘要: The saw blade includes a plate supporting a plurality of teeth about the periphery thereof. Each tooth consists of a cutting tip supported in a tip pocket. The tips are brazed to the tip pockets with no side clearance taper created on the tips. The side faces on the tips are parallel to each other. The tip pockets are stamped into the blade using a high volume stamping process that employs a semi-circular relief at the proximate trailing corner of the tip pocket to receive the proximate trailing corner of the cutting tip. The relief can be formed in a high volume stamping process because it eliminates the need for a sharp corner. The relief accommodates the sharp edge of the cutting tip and allows the cutting tip to be properly seated on the tip pocket for connection thereto.
