摘要： A valve-tray assembly and method for lighter fluid heavier fluid contact towers. The active area of the tray is constructed with valves having multiple lighter fluid discharge areas facilitating improved mass transfer efficiency. The valves include first and second support legs oriented in line with the heavier fluid flow with both legs and the valve top constructed with apertures wherein the heavier fluid may flow into engagement with the lighter fluid passing from beneath the tray up, through and out of the valve.

摘要： Apparatuses and systems for removing heavy hydrocarbons from a solvent stream are disclosed herein. The apparatuses extract heavy hydrocarbons into light hydrocarbons and provide a solvent stream having the heavy hydrocarbons removed. Two water washing steps are used to remove residual solvent from the heavy hydrocarbon solution in light hydrocarbons. In some embodiments, the second water wash is used for processing subsequent batches of the solvent stream. The heavy hydrocarbons and solvent can be recovered and processed further. Methods for removing heavy hydrocarbons from a solvent stream are also disclosed herein.

摘要： Embodiments disclose a process for converting gaseous alkanes to higher molecular weight hydrocarbons, olefins or mixtures thereofs wherein a gaseous feed containing alkanes may be reacted with a dry bromine vapor to form alkyl bromides and hydrobromic acid vapor. The mixture of alkyl bromides and hydrobromic acid then may be reacted over a synthetic crystalline alumino-silicate catalyst, such as a ZSM-5 or an X or Y type zeolite, at a temperature of from about 250° C. to about 500° C. so as to form hydrobromic acid vapor and higher molecular weight hydrocarbons, olefins or mixtures thereof. Various methods are disclosed to remove the hydrobromic acid vapor from the higher molecular weight hydrocarbons, olefins or mixtures thereof and to generate bromine from the hydrobromic acid for use in the process.

Alkyl bromides may be reacted over a catalyst in at least one conversion reactor to produce at least an effluent stream comprising higher molecular weight hydrocarbons and hydrogen bromide. A portion of the catalyst may be removed from the conversion reactor. The portion of the catalyst may be contacted with a stripping gas to displace hydrocarbons from the portion of the catalyst. The portion of the catalyst may be contacted a first inert gas. The portion of the catalyst may be contacted with oxygen to form a regenerated catalyst by removal of coke. The regenerated catalyst may be contacted with a second inert gas. At least a portion of the regenerated catalyst may be introduced into the conversion reactor.
