Abstract: System and method for predicting the rate of deterioration in one or more items of process equipment which are subject to deterioration by one or more deterioration mechanisms. The system includes a first item of process equipment which receives an inlet stream including a feedstock or derivative thereof, and discharges one or more outlet streams which can be fed to the item of process equipment. A data processor which is a programmed computer including at least one rate model for the first item of process equipment receives values of one or more properties of the feedstock and calculates predicted rates of deterioration by the one or more deterioration mechanisms for the first item of process equipment from the values of one or more of the feedstock properties. The data processor additionally provides an output containing information relating to the predicted rates of deterioration by the one or more deterioration mechanisms for the first item of process equipment.

Abstract: A process is disclosed for removing highly deleterious non-basic nitrogen compounds upstream from an acid catalyzed thiophene alkylation process using adsorbents capable of adsorbing the non-basic nitrogen compounds.

Abstract: An arrangement and method for removing a shaft from a gearbox housing without having to totally disassemble the housing. One embodiment incorporates a compressible retaining ring that circumscribes the output shaft. The retaining ring expands when the shaft has been inserted to a proper depth within the housing to lock the shaft in place. When it is necessary to remove the shaft, axial force is applied to the shaft that causes the retaining ring to compress and unlock the shaft. Another embodiment of the invention has an aperture in the housing of the gear box. The aperture is used to gain access to the retaining ring that locks the shaft within the housing. Once the retaining ring is removed, the shaft may then slide out of the housing. A plug member is used to cover the aperture when it is not necessary to remove the shaft.
