Electrostatic bead bed separator for separating suspended solid particles from high resistivity oils, fine glass beads used in the micro glass bead bed, a method for separating suspended solid particles from the oil of the high resistivity and system for obtaining the key bottoms oil of the ultra-high purity by separating the suspended solid particles containing the catalyst particles from the main tower bottom oil of high resistivity

摘要

PURPOSE: To make a separator, which removes contaminating particles from hydrocarbon oils, suitable for separating catalyst fines from various oil fractions by forming glass beads with a chemical composition incorporating silicon oxide and potassium oxide with respective specified contents. ;CONSTITUTION: Glass beads, which form a glass beads bed 54 of an electrostatic beads bed separator 50, are formed with fine glass beads, formed with a chemical composition comprising at least 50% silicon oxide and at least 10% potassium oxide. Besides the chemical composition can comprise one or more kinds of oxides of sodium, cesium, rubidium or lithium For example, 50-90% SiO₂, 0-25% Al₂O₃, 10-40% K₂O, 0-15% CaO, 0-12% MgO and 0-5% TiO₂ area formulated. In addition, beads are spherical bodies with about 1/32 to about 1/4 inch average diameter.;COPYRIGHT: (C)1994,JPO
