METHOD AND APPARATUS FOR WITHDRAWING PARTICULATE SOLID FROM A HIGH PRESSURE VESSEL

摘要

The particulate solid is maintained in a bed in contact with a liquid within a high pressure vessel. The particulate solid is supported in the vessel in a cone-like configuration. A discharge tube is provided communicating with the particulate solid running from the bottom of the cone externally of said vessel and pressure on the supported particulate is produced to discharge said particulate out of said vessel via the discharge tube.
