    摘要: A catalytic hydrocracking reactor vessel includes enhanced components for the conversion of a hydrogen gas and fossil fuel feedstream to light liquid hydrocarbons. The reactor vessel comprises one or more of a reactor cup riser with a helical cyclonic separator conduit for separating a liquid and vapor product stream to provide an essentially vapor-free liquid recycle stream; a grid plate bubble cap with wall housing having serrated edges for producing small hydrogen bubbles of increased total surface area of bubbles at lower pressure drop; a feedstream inlet pipe sparger containing rows of downward directed slots for even distribution of the feedstream across the cross-sectional area of the reactor and providing free drain of solid particles from the sparger; and optionally a liquid recycle inlet distributor containing vertically curved plates for creating a whirling motion in the liquid recycle stream for better mixing with the feedstream with minimal solids settling.

    摘要: A setting leg for a polymerisation reactor connected to the lower part of the loop reactor (1). A conduit (2) is welded to the loop reactor and leads to upper valve (3) and lower block valve (4). Downstream of the lower block valve (4) is a further conduit (5) which leads to a lower region (6) and to a product take off (PTO) valve 7. Conduit (5) has a significantly greater cross-sectional area than conduit (2). In use, the block valves (3) and (4) are always open to allow slurry from the reactor loop to enter the settling leg. The PTO valve (7) is regularly opened to allow the settled polyethylene “fluff” to be rapidly expelled along conduit (8). The greater area of conduit (5) significantly increases the settling rate ad polymer concentration of the polyethylene “fluff”.
