A continuous online process for rejuvenating whole stream of contaminated lean sulfolane in an extraction system is provided. A rejuvenator is installed in the solvent: circulation loop to remove the contaminants continuously to keep the solvent clean, effective and less corrosive. The rejuvenator includes a high pressure vessel with a removable cover and a round rack with vertical stainless steel tubes fitted in the high pressure vessel. A magnetic bar is placed in each stainless steel tube. A screen cylinder is installed outside the ring of stainless steel tubes. As the contaminated sulfolane is passed through the rejuvenator, the rejuvenator picks up contaminants. The rejuvenator can be dissembled to remove the contaminants periodically. The rejuvenator is simple in construction, reliable in operation, and low in operation and maintenance costs. With this rejuvenator, the extraction system operates at high efficiency and high capacity without the dreaded corrosion.

Process and apparatus for online rejuvenation of contaminated sulfolane solvent

A novel design of filters for removing iron rust particulates and other polymeric sludge from refinery and chemical process streams that are paramagnetic in nature is provided. The performance of these filters is greatly enhanced by the presence of the magnetic field induced by magnets. Basically, the filter comprises a high-pressure vessel with means to support the plurality of magnets in the form of bars or plates that are encased in stainless steel tubes or columns. Filters with various configurations are disclosed for accommodating the removal of contaminants from the process streams of different industries, with high efficiency for contaminants removal, simple construction, low operational and maintenance costs, and low hazardous operation.

A method for recovering reforming catalyst comprises obtaining spent reforming catalysts; immersing the spent reforming catalysts with different degrees of aging into a light solution to obtain immersed catalysts and allowing the light solution to enter pores in the spent reforming catalysts to lower a pseudo-skeletal density of each spent reforming catalyst to obtain immersed catalysts; immersing the immersed catalysts into a heavy solution that has a density greater than pseudo-skeletal density of the immersed catalysts and replacing the light solution in the pores in the immersed catalysts by the heavy solution to increase density of the immersed catalysts; and awaiting the immersed catalysts to settle in the heavy solution to obtain settled catalysts, wherein different settling velocities due to aging creates layers of settled catalysts. Therefore, the reforming catalysts with different degrees of aging are easily classified into different layers, which can be reused for cost saving.
