Abstract: Certain embodiments may generally relate to systems and methods for developing and improving compact electrocoalescers for in-line dehydration of water-in-oil dispersions. A compact electrocoalescer may include a casing, and a plurality of bare or insulated conical-shaped electrodes housed in the casing. The electrodes may include a metal mesh structure. The electrodes may also be truncated at the apex, and alternatively connected to a power supply and ground. The electrodes may further be stacked in a manner such that at least one electrode is at least partially nested within at least another electrode.

Abstract: Porous spheroidal alumina particulate solids that comprise an alumina filler in an amount of about 0.1% to about 25% by weight of Al2O3 and have a mechanical resistance to shocks measured by spheres impacting against a target at the speed of 20 m/s such that the fines fragmentation percentage, of a size of less than 50% of the average size of the initial spheres, is less than 5% by weight. Preparation of these spheres by coagulation in drops from an oil-in-water-type emulsion. Application of these spheres as a catalyst substrate or as an adsorbent.

Abstract: This invention relates to a method for the production of gases free from particulate contaminants, for use in driving gas turbines without causing fouling or corrosion of the blading.The method comprises feeding a gas contaminated with particulate material, for instance produced by the combustion or gasification of coal, and a tackifying material, such as a crackable hydrocarbon or an inorganic compound, to a collection medium, preferably a fluidized particle bed, maintained at a temperature whereat the tackifying material becomes sticky and is deposited on the collection medium. The contaminants are removed by becoming stuck thereon.
