Disclosed are methods and systems for removing a highly reactive polymer precursor such as acetaldehyde and acetone from a hydrocarbon gas stream. Embodiments may disclose a method for removal of carbonyls comprising providing a hydrocarbon gas stream comprising a carbonyl, providing a liquid bisulfite stream, and contacting the hydrocarbon gas stream and liquid bisulfite stream in a mass transfer device wherein at least a portion of the carbonyl reacts with the bisulfite to form a solid adduct that is soluble in the liquid bisulfite stream.

Treatment of hydrocarbon streams, and in one non-limiting embodiment refinery distillates, with reducing agents, such as borohydride and salts thereof, alone or together with at least one co-solvent results in reduction of the sulfur compounds such as disulfides, mercaptans, thiophenes, and thioethers that are present to give easily removed sulfides. In one non-limiting embodiment, the treatment converts the original sulfur compounds into hydrogen sulfide or low molecular weight mercaptans that can be extracted from the distillate with caustic solutions, hydrogen sulfide or mercaptan scavengers, solid absorbents such as clay or activated carbon or liquid absorbents such as amine-aldehyde condensates and/or aqueous aldehydes.

Provided herein in is a method of removing phosphorus from a liquid hydrocarbon that includes the steps of (a) contacting the liquid hydrocarbon with an aqueous solution that comprises an oxidizing agent to form a reaction mixture that comprises an aqueous component and a hydrocarbon component, wherein the liquid hydrocarbon comprises at least an alkene.sub.(C4-30), and a phosphine.sub.(C?30); (b) reacting the oxidizing agent with the phosphine.sub.(C?30) to form the corresponding phosphine oxide.sub.(C?30); and (c) separating the aqueous component from the hydrocarbon component, thereby removing the phosphine oxide.sub.(C?30) from the liquid hydrocarbon.

The present invention relates to integrated processes for using hydroformylation reaction strategies to efficiently convert ethylene in ethylene feed mixtures into C3 products (i.e., products comprising 3 carbon atoms) such as propionaldehyde, 1-propanol, propylene, propanoic acid, and the like. An aspect of the present invention is to partially purify a feed comprising an ethane/ethylene mixture rather than to attempt more complete purification. In contrast to substantially complete purification of ethylene, partial purification is technically and economically feasible at lower cost and allows hydroformylation to be practiced at high productivity and with a lower hydrogen and CO requirement. The lower volumes of such syngas used in the hydroformylation reaction, as well as a more favorable profile of leftover reactants in following hydroformylation makes recycle strategies much easier to practice.

We provide a catalytic process to reduce an organic halide in a hydrocarbon, comprising: a. producing the hydrocarbon comprising the organic halide in a process unit; and b. contacting the hydrocarbon comprising the organic halide with a metal chloride under anhydrous conditions in a halide removal vessel to produce a contacted hydrocarbon having from 50-100 wt % of a total halide in the hydrocarbon removed. We also provide an apparatus for performing this process.
