A coke catching apparatus for use in hydrocarbon cracking to assist in the removal of coke and the prevention of coke build up in high coking hydrocarbon processing units. The apparatus includes a grid device for preventing large pieces of coke from entering the outlet of the process refining equipment while allowing small pieces of coke to pass through and be disposed of. The coke catching apparatus can be easily disassembled to be removed from the refining process equipment and cleaned.

A natural gas liquid plant is retrofitted with a bolt-on unit that includes an absorber that is coupled to an existing demethanizer by refrigeration produced at least in part by compression and expansion of the residue gas, wherein ethane recovery can be increased to at least 99% and propane recovery is at least 99%, and where a lower ethane recovery of 96% is required, the bolt-on unit does not require the absorber, which could be optimum solution for revamping an existing facility. Contemplated configurations are especially advantageous to be used as bolt-on upgrades to existing plants.

A system for crude oil desalting and dehydration includes a separation vessel defining a cavity extending along a central axis having a substantially-vertical orientation. The separation vessel comprises a first distributor configured to distribute a mixture within the cavity of the separation vessel, and a second distributor configured to distribute a wash fluid within the cavity of the separation vessel. The mixture comprises crude oil, water, dissolved salts, free salts, or combinations thereof, and the wash fluid comprises an aqueous fluid. The first distributor is disposed within the cavity below the second distributor, and an interface level controller is configured to detect an interface between an oil phase and an aqueous phase and to maintain the interface within a predetermined range within the cavity.

The present invention relates to a process for preparing liquid hydrocarbons by the Fischer-Tropsch process integrated into refineries, in particular comprising recycling streams from the steam reforming hydrogen production process as the feedstock for the Fischer-Tropsch process.

For the shipping industry, these fuels provide solutions to long outstanding technical problems that heretofore hindered supply of low sulfur marine fuels in quantities needed to meet worldwide sulfur reduction goals. When ships on the open seas burn cheap low grade heavy bunker oils high in sulfur, nitrogen and metals, the SOx, NOx, and metal oxides go to the environment. This invention converts essentially all of each barrel of crude feed to a single ultraclean fuel versus conventional refining where crude feed is cut into many pieces, and each piece is sent down a separate market path meeting various different product specifications. When in port, ships can generate and sell electricity to land based electrical grids to offset fuel cost in an environment-friendly manner.
