Abstract

The silica gel is produced in two main shapes, regular and irregular. Due to the decreasing of gas mobile phase pressure drop, increasing the contact surface area and lowering friction dust effects, SPHERICAL SILICA GEL is used in the adsorbing towers of oil and gas industries. The most important methods for producing SPHERICAL SILICA GEL are OIL DROP and molding. According to the studying and laboratory experiments done in this research, the OIL DROP method was selected. This method based on the immiscibility of SILICA SOL (prepared from sodium silicate, sulfuric acid and other additives) with some organic oils and solvents. Dropped SILICA SOL with a pH equal to 4 after passing through an oil phase is solidified into spherical hydrogen then SPHERICAL SILICA GEL is produced after washing and drying steps. Therefore a granulating apparatus for producing SPHERICAL SILICA GEL was designed and constructed, byu which a SPHERICAL SILICA GEL having the technical characteristics of a one used in oil industries (red sorbead) was product.In this article many effective factors like pH of SILICA SOL, oil temperature (65-70 °C), viscosity of the oil (46-67 cSt.) and hydrogel washing condition were have been studied.
