Abstract: An apparatus and method are provided for the defluorination of a liquid hydrocarbon mixture, containing organic fluorides, produced during the conversion of hydrocarbons using a fluorine-containing catalyst. In one embodiment, both a thermal means and a contacting material are used to effectuate a more complete defluorination. The liquid hydrocarbon mixture is extracted from a distillation column and heated sufficiently in the thermal means to decompose at least some of the organic fluorides. The effluent from the thermal means is separated into a vaporous and a liquid effluent. The liquid effluent is passed to the bottom of the distillation column where it undergoes further defluorination through contact with the contacting material.

Abstract: A delayed coker drumhead handling apparatus, which includes remotely operable trammel pivot apparatus to open and close the coke drum by moving the drumhead downwardly and laterally, such that the apparatus is especially suitable for use in areas of restricted clearance to the operating deck or otherwise confined space.

Abstract: A coke drum unheading device having an actuator system operable from a location remote from a drum outlet. The actuator is adapted to move a drumhead between closed and open positions and to retain the drumhead in a closed position under load.
