    Abstract: 本发明涉及烯烃气相聚合用设备,其中主要包括流化床反应器和至少一根聚合物排料管,所说的排料管带有隔离阀并且将反应器的垂直侧壁与封闭斗连通,该排料管离开反应器的垂直侧壁向下延伸,使所说排料管的每部分均与水平面间具有35~90°夹角。本发明还涉及在流化床反应器中使烯烃连续气相聚合的方法,其中包括使聚合物经由排料管从反应器的垂直侧壁排入封闭料斗中,使排料管中产生的全部聚合物流均沿着向下与水平形成的倾角A排出,该倾角A至少等于该聚合物静止角β且又不超过90°。本发明改善了封闭料斗的充满程度而且降低了随聚合物排出的气体量。

    Abstract: 公开了用于把酸催化剂从在较低蒸汽压力水平下运载液态酸的运输设备传输到在更高压力水平下贮存液态酸的烷基化过程的生产容器中,同时使损失到环境中的酸蒸汽减至最小。经在运输容器和贮罐间使用较小体积的压力锁气室而实现酸传输而不必使生产容器排气。在较佳实施方案中,小体积压力锁气室也用作为补充酸的贮罐,按需要把补充酸给入烷基化过程。

    Abstract: Disclosed herein is an improved gas gate for interconnecting regions of differing gaseous composition and/or pressure, more particularly between atmosphere and a vacuum. The gas gate includes a cylinder within a housing situated between the regions of differing gaseous pressure, wherein the gas gate provides for choke mode transonic flow of air leaks between the regions. A web of substrate material is adapted to move between the regions with at least one roller in a first region and at least one roller in a second region. The rollers are positioned to create sufficient tension as the web advances over the top peripheral portion of the cylinder between the two regions or under the bottom peripheral portion of the cylinder between the two regions.
