A system may include a catch tray coupled with a flow distributor. A mesh screen and carriage may be positioned within the catch tray. A drive bar may be coupled with the carriage and a pitman arm. A gear box may be coupled with a motor and the pitman arm. A process may include distributing contaminated fluid onto the mesh screen. A screen plane of the mesh screen may be at a screen angle that is oblique relative to the direction of the force of gravity. The screen plane is defined by a top surface of the mesh screen. The process may include moving the carriage in a reciprocating linear motion by rotating the pitman arm, and spraying a liquid onto the mesh screen. Liquid may flow through the mesh screen forming clarified liquid, and contaminate may move along the top of the mesh screen to a contaminate outlet.

The present invention relates to an extraction apparatus for extracting at least one constituent in a substance. The extraction apparatus comprises an extractor, an extraction separator and an extraction condenser. The extractor is used to mix the substance and an extraction fluid, wherein the extraction fluid is a subcritical fluid. The extraction separator is connected to the extractor for receiving and heating the extraction fluid to gasify the extraction fluid and to separate the constituent and the gasified extraction fluid. The extraction condenser is connected to the extraction separator and the extractor for receiving and liquefying the gasified extraction fluid from the extraction separator and sending the liquefied extraction fluid to the extractor.

Monitoring drill cuttings suspended within a drilling fluid with one or more cuttings detection devices as the drill cuttings traverse one or more shaker screens of a shaker. Drill cuttings data of the drill cuttings is then generated with the one or more cuttings detection devices. Analyzing and processing the drill cuttings data with one or more processors included in a data acquisition system and thereby generating processed drill cuttings data. The processed drill cuttings data is indicative of at least one of a cuttings size distribution and a density of the drill cuttings. One or more operational parameters of the shaker may then be modified based on the processed drill cuttings data.

A combined hopper and shaker assembly which can be used at least in processing excavation or other remains. The assembly features a hopper that can be pivoted (through operation of a hoist/sling) to cause the contents of the hopper to be fed via gravity through an exit chute onto the shaker. The hopper includes splash guards or sidewalls on the portions thereof that are proximate the pivot axis and an internal shape along the exit chute so as to guide the contents of the hopper toward the exit chute.
