摘要： A process and a plant for producing an olefin stream from a hydrocarbon mixture feed stream, wherein the olefin stream is depleted as regards its content of oxygen-containing organic compounds (oxygenates) as compared to the feed stream. The hydrocarbon mixture feed stream is charged to a separation column operated by a thermal separation process, for example to a distillation column, wherein a material stream enriched in oxygenates is withdrawn via a side outlet and removed from the process. The process according to the invention is particularly useful for processing the product streams obtained in the olefin synthesis by an OTO process.

摘要： A method for producing a synthesis-gas product gas and a vapor stream includes catalytic steam reforming a hydrocarbonaceous feedstock in a steam reformer. The hot synthesis-gas product gas stream is cooled in a heat exchanger to form a cooled synthesis-gas product gas stream and a first partial vapor stream, which is supplied to the product vapor stream. The reforming furnace is operated so as to burn a burner feedstock in burners, cool a hot flue gas stream from the burners in a heat exchanger to form a cooled flue gas stream and a second partial vapor stream, and separate the cooled flue gas stream into a waste gas stream and a flue gas recirculation stream. The flow of the recirculated flue gas is increased with decreasing flow of the synthesis-gas product gas to obtain an approximately constant product vapor stream by increasing the second partial vapor stream.

摘要： A method for producing methanol from a synthesis gas containing hydrogen and carbon oxides with a high content of inert components includes passing the synthesis gas through a synthesis reactor so as to catalytically convert a part of the carbon oxides to methanol. The methanol is separated from the obtained mixture from the reactor. The mixture liberated from methanol is separated into a cycle stream and a purge stream. The cycle stream is recirculated so as to form a synthesis circle and combined with a fresh gas stream including hydrogen and carbon oxides before being charged into the synthesis reactor. The purge stream is supplied to a secondary reactor so as to catalytically convert a further part of the hydrogen and carbon oxides to methanol. Further methanol is separated the obtained mixture including synthesis gas, inert components and methanol vapor.
