摘要： A low energy process for producing acetic acid by the carbonylation of methanol is disclosed. The process involves a rhodium-catalyzed system operated at less than about 14% water utilizing up to 2 distillation columns. The process is preferably controlled such that the product stream has a low level of propionic acid impurity and the level of aldehyde impurities is minimized by way of aldehyde removal or minimizing aldehyde generation. The level of iodides is controlled by contacting the product, at elevated temperatures, with ion exchange resins. In preferred embodiments, at least one silver or mercury exchanged macroreticular strong acid ion exchange resin is used to purify the product. The high temperature treatment provides the added benefit of controlling the Color Value (Pt—Co units) of the product stream.

摘要： A method and apparatus for sequestering entrained or volatile catalyst species in a carbonylation process includes contacting the product stream with a vinyl pyridine or a vinyl pyrrolidone resin bed which is operative to sequester entrained or volatile catalytic species. The invention is particularly useful in connection with the iridium catalyzed carbonylation of methanol wherein the loss of entrained or volatile catalyst species depletes the catalytic content of the reactor. The resin may be digested in order to recover the catalytic metals.

摘要： The converting of an existing methanol plant to make acetic acid is disclosed. The converted plant utilizes the steam reformer (10) to which (a) a hydrocarbon ,e.g., natural gas, or a lower alkanol, e.g., methanol, and (b) steam (water) are fed. Syngas is formed in the reformer (10). All or part of the syngas is processed to separate out carbon dioxide (24), carbon monoxide (30) and hydrogen (32), and the separated carbon dioxide (24) is fed either to the existing methanol synthesis loop (12) for methanol synthesis, or back into the feed to the reformer (10) to enhance carbon monoxide formation in the syngas (18). When a lower alkanol is fed to the reformer (10), the methanol synthesis loop (12) is shutdown and isolated from the rest of the plant. Any remaining syngas (38) not fed to the carbon dioxide separator (22) can be converted to methanol in the existing methanol synthesis loop (12) along with carbon dioxide (24) from the separator (22) and/or imported carbon dioxide (25), and hydrogen (35) from the separator (28). The separated carbon monoxide (30) is then reacted with the methanol (36) to produce acetic acid (40) or an acetic acid precursor by a conventional process. When the methanol synthesis loop (12) is shutdown, an imported source of methanol is used.
