Abstract: A vertical drier system and method for managing oil well solids and liquids includes a vertical drier; a hopper for well drilling cuttings mixed with residual liquids; and an enclosed drag chain conveyor having an opening into the hopper for picking up drill cuttings and associated liquids. The enclosed drag chain conveyor extends from the hopper to a vertical drier, there being an opening in said enclosed drag chain located at said vertical drier, whereby drilling cuttings and associated fluids being conveyed by said drag chain are delivered to said vertical drier for drying. The enclosed drag chain conveyor returns again to said hopper in a continuous enclosed loop except for the openings.
