Abstract: The invention provides for an improved seal leg and method for transferring particulate solids in a non-fluidized condition from a first pressure zone to a second pressure zone while controlling the level of solids in the first pressure zone or in the seal leg. A relatively uniform pressure gradient is produced across the length of the seal leg by bleeding gas into or out of the seal leg along its length. Bleeding gas as aforesaid permits the use of a shorter seal leg and a smaller diameter seal leg for a given solids flow rate as compared to a seal leg not provided with means for bleeding gas in or out along its length. The pressure gradient along the length of a seal leg not provided with means for bleeding gas in or out along its length will be highly nonuniform resulting in retarded solids flow due to localized high pressure gradients and a low overall average pressure gradient resulting in a substantial length requirement for the seal leg to maintain a pressure seal.
