MUD CLEANING MACHINE
Walter L Spruiell, Jerry L Spruiell A machine for cleaning drilling muds by removing entrained solids and impurities and returning cleansed and for recycling. The machine comprises a centrifuge desander operatively connected to a plurality of cooperating conical desilters to remove gases and separate materials of varying densities. Initially muds containing solid materials are pumped at a controlled pressure from the cleaning bed into an initial cyclone chamber, where, under increasing centrifugal force, the processed mud is separated into relatively heavier and lighter components, which are transmitted via separate pathways to twin chambers in the lower level compartment of a particle separating drum. The first chamber of the drum receives heavier materials and transmits them to a large desander cone where the heaviest impurities are removed; the second drum chamber receives the lighter components which are further separated and delivered to a network of desilter cones which output properly cleansed mud. The purified output of the large densander cone is transmitted directly back into the cleaning bed reservoir, and £37 dirty + 38 + 0 mud is thus recycled continuously until + 3 7 clean enough + 38 + 0 to escape the loop by exiting through the desilter cones. Freed air and gasses are discharged at controlled rates to be burned or dispersed into the environment through a third stage, which is in fluid flow communication with the initial stage and the desilter stage. Through the gas removal construction disclosed, the efficiency of the various stages of the cleaning processes is increased, and drilling mud losses are minimized. + RE
4670148 APPARATUS AND METHOD FOR WITHDRAWING GASEOUS DECOMPOSITION PRODUCTS
FROM A REFUSE DUMP Reinhard Schneider, 6300 Giessen, Federal Republic Of Germany
An apparatus and method for withdrawing gaseous decomposition products from a refuse dump. Disposed at various locations in the refuse are gas collection mechanisms, such as gas wells, drainage systems, etc., each of which is connected via a gas withdrawal line with a collector, from which the gas is withdrawn for further utilization. Disposed in each gas withdrawal line is a sensor and a regulatable shutoff device. The sensor transmits the content of a characteristic constituent of the gas flow in a given gas withdrawal line to a measuring and control unit, which monitors the gas flow volume as a function of a comparison of the sensor signals with preset threshold values. If the sensors indicate that the content of the characteristic constituent of the gas flow exceeds or drops below the preset threshold values, the measuring and control unit opens or closes the associated shutoff device by an appropriate amount.

4670159 P R O C E S S FOR O B T A I N I N G PURIFIED WATER FROM WET SLUDGES AND SLURRIES OF SOLID MATERIALS David Garrett, Alfred Bacher assigned to Benmol Corporation The invention relates to a process for obtaining purified water from wet sludges and slurries of solid materials by treating these materials with a clathrate forming agent at a temperature above the freezing point of water to form a solid clathrate and dewatered solid material. The clathrate and solid material are then separated and the clathrate decomposed to give purified water and clathrate forming agent.
