Abstract
Methods and systems for reducing an average particle size of blackwater solids is disclosed. A vessel is configured to receive a blackwater stream through a one-way inlet. The one-way inlet is configured to allow the blackwater stream into the vessel and prevent backflow. The blackwater stream contains blackwater solids and water. A device in a bottom portion of the vessel is configured to receive the blackwater and comminute the blackwater solids. A recirculating pump is configured to recirculate the blackwater stream under pressure through the device until the average particle size of the blackwater solids is reduced below a size threshold, resulting in a sized blackwater stream.
