  • Patent number: 11254626
    Abstract: Disclosed herein are processes for producing and separating ethane and ethylene. In some embodiments, an oxidative coupling of methane (OCM) product gas comprising ethane and ethylene is introduced to a separation unit comprising two separators. Within the separation unit, the OCM product gas is separated to provide a C2-rich effluent, a methane-rich effluent, and a nitrogen-rich effluent. Advantageously, in some embodiments the separation is achieved with little or no external refrigeration requirement.

  • Patent number: 8277639
    Abstract: The invention is directed to a process comprising feeding high TAN feedstreams to a steam cracker, whereby naphthenic acids in the feedstreams are substantially converted to CO, CO2, and low amounts of smaller acids (e.g., formic, acetic, propionic, and butyric acids). The feedstream is preferably a high TAN feedstream comprising crude or high TAN feedstream which has previously been subjected to a refinery process to remove resid.

  • Patent number: 5484578
    Abstract: A distributor system for uniformly directing vapor and liquid across the surface of a fixed bed of solids in a downflow reactor comprising a distributor tray, and a plurality of open-ended downpipes extending through the tray. A first array of the downpipes has a plurality of vertically spaced elevations of holes above the level of the tray. A second array of the downpipes has at least one elevation of holes at substantially the same height above the level of the tray as one of the upper elevations of holes in the first array of the downpipes. But, the second array has no elevation of holes corresponding to the lowermost elevation of holes, and possibly other lower elevations of holes, in the first array of downpipes. The absence of the lowermost holes in the second array of downpipes causes the liquid flow rate through the distributor tray at a given liquid height to be reduced when that liquid height falls below the elevation of the holes second from the bottom in the first array.
