    摘要： Process to produce integer glandular trichomes from resin rich plants, comprising the steps of dislodging the integer glandular trichomes from the plants by the means of a pressurized cold water jet, and sieving the resulting water flow across a series of sieving screens being in a progressively decreasing hole size order.

    摘要： A process for refining sand for use as frac sand includes the steps of passing the sand through a first fines separation stage to remove fine particles of contaminant from the sand, reducing the water content of the sand (such as to less than 20%), passing the sand into an attrition scrubber unit containing moving blades to delaminate clay and other contaminants from the sand grains, passing the sand from the attrition scrubber unit through a second fines separation stage to separate fine contaminants from the sand, and dewatering the resulting sand product in a further dewatering stage.

    摘要： An aerated grit tank is provided having a longitudinally extending control wall dividing the tank into parallel lift and settling chambers. An air discharge apparatus is provided at the bottom of the lift chamber to induce an upward flow of sewage causing a generally helical flow of sewage around the control wall. The control wall is supported in the tank by mechanisms selectively operable to vertically position the wall with a bottom longitudinally extending edge in predetermined spaced relationship to a bottom floor of the tank whereby the velocity of the cross currents may be effectively controlled. One form of the structure has a single control wall unit while a second form of the invention has two wall forming panels with an uppermost panel supported in fixed relationship to the tank and a lowermost panel supported for vertical displacement.

    摘要： This invention relates to an apparatus and process for extracting bitumen from mineral particles such as sand. The invention avoids many of the problems of the conventional hot water or solvent extraction processes by using an abrading process to remove the bitumen or oil from sand particles, using cool water and little solvent. The abrading process involves agitating a pulp of tar sand and water, preferably with some small amount of diluent, and then moving this around an annular space at a speed low enough to allow settling of clean sand to form a sand bed in contact with the moving pulp, the speed being high enough to prevent settling of bitumen coated sand particles, so that the bitumen is abraded from the sand particles and rises in the pulp. Fines and clay which are removed with the water and bitumen can be separated from the water, after removal of the bitumen, to give a sludge suitable for mixing with the clean sand prior to disposal.
