ULTRA LOW PRESSURE CONTINUOUS CATALYST TRANSFER WITHOUT LOCK HOPPER

An apparatus is presented for the transferring of catalyst from an upstream vessel to a downstream vessel. The apparatus includes a non-mechanical valve and a transfer line, wherein a lift gas provides for carrying catalyst through the transfer line. The non-mechanical valve has a catalyst inlet and a lift gas inlet to provide for a consistent flow to limit or reduce pipe erosion and catalyst attrition, as well as to provide catalyst and lift gas to the transfer lines. 提出了种用于将催化剂从上游容器输送到下游容器的设备。该设备包括非机械阀和输送管线，其中提升气体用于携带催化剂经过输送管线。非机械阀具有催化剂入口和提升气体入口以提供恒定流动，从而限制或减少管道侵蚀和催化剂磨耗，以及向输送管线提供催化剂和提升气体。
