The present invention is directed to a drilling fluid reclaimer. The reclaimer has at least one adjustable screen assembly for providing a leveling filter for reclaimed drill fluid. Used drill fluid is placed at the screen assembly at the front the of the screen assembly. The at least one screen is vibrated to separate large particulate matter from liquid drilling fluid. A second screen is provided for additional filtering. Large particulate matter is expelled by a chute at the back of the screen assembly. Drilling fluid passing through the screen is reclaimed for use with a drilling system.

According to an example aspect of the present invention, there is provided, an apparatus and a method for treating mixtures of liquids and solids. The apparatus comprises a casing and a rotor mounted inside the casing and having an inner volume delineated by an outer surface. The outer surface is provided with flow connections to the inner volume and configured to be rotated within the casing. The casing and the rotor are set in a vertical position.

A drilling mud remediation and drilling cutting treatment device and method. There are three main components: a vacuum liquid solid separator; a pelletizer; and an induction furnace. The liquid solid separator has a seamless filter belt configured to carry a mixture of liquids and solids over a vacuum. A slurry comprised of drilling mud and cuttings is deposited on the filter belt. An applicator ensures that the slurry is deposited evenly across the entire filter belt at a uniform thickness. The vacuum removes most of the liquids for further treatment and reuse. The solids are transferred to a pelletizer which compacts them into relatively uniform pellets while removing much residual liquid. The pelletized cuttings are then passed through an induction furnace, which removes any residual liquids, renderings the cuttings safe for disposal.

Processes for recovering a purified aromatic carboxylic acid include contacting a crude aromatic carboxylic acid with hydrogen in the presence of a catalyst in a hydrogenation reactor to form a purified aromatic carboxylic acid; crystallizing the purified aromatic carboxylic acid to form a solid/liquid mixture comprising purified aromatic carboxylic acid solids; filtering the solid/liquid mixture in a rotary pressure filter apparatus to remove a liquid filtrate, washing the solid/liquid mixture in the rotary pressure apparatus with a wash fluid to form a washed solid/liquid mixture, and drying the washed solid/liquid mixture in the rotary pressure apparatus with an inert gas to form a filter cake comprising purified aromatic carboxylic acid solids and a wet gas stream; withdrawing the wet gas stream from the rotary pressure filter apparatus while maintaining the wet gas stream at a pressure above ambient; and recovering the purified aromatic carboxylic acid solids from the filter cake.
