The COpure process Technology

This technology provides a unique low cost solution to carbon monoxide recovery. Process improvements have made COPure a highly reliable source of carbon monoxide for downstream manufacture of chemicals and pharmaceuticals. COPure can be considered whenever recovery of high purity carbon monoxide is required. This is especially the case when the feed gas contains significant quantities of nitrogen and/or carbon dioxide, which need not be removed.

The COPure process selectively removes carbon monoxide by complexation/ decomplexation of carbon monoxide in a proprietary solvent containing cuprous aluminum chloride (CuAlC1₄) dissolved in an organic liquid such as toluene.

Essentially the COPure process technology absorbs carbon monoxide and slips carbon dioxide, nitrogen and other gases. Typical product recovery is 98%, and typical purity is 99%. (Higher recoveries and purities are achievable.)

The COPure process may contain various post treatment or pretreatment steps that may include, compression, hydrogenation, dehydration, hydrogen sulfide removal, carbon dioxide removal etc. that are optimized for your process and plant configuration. For example if you were going to perform a Fischer-Tropsch reaction then purification of hydrogen and recombining it with the purified carbon monoxide would be included in the process.

Cold Box (Installation for producing carbon monoxide by cryogenic distillation)

An installation for producing carbon monoxide by cryogenic distillation comprising: a) a heat exchanger for cooling and partially condensing a gas mixture containing carbon monoxide, hydrogen and nitrogen to produce a cooled and partially condensed gas mixture; b) a separator for separating the cooled and partially condensed gas mixture to produce a hydrogen-enriched gas and a carbon monoxide-enriched liquid; c) means for conveying the cooled and partially condensed gas mixture from the heat exchanger to the separator; d) a stripping column and means for conveying at least part of the carbon monoxide-enriched liquid thereto; e) means for withdrawing a hydrogen-enriched gas from the top of the stripping column and means for withdrawing a hydrogen-free liquid from the bottom of the stripping column; and f) a distillation column, means for sending a stream of the hydrogen-free liquid to a first intermediate point of the distillation column, means for withdrawing a bottom liquid from the distillation column, means for withdrawing an overhead gas (RSD N2) from the distillation column and means for withdrawing an intermediate fluid at a second intermediate point of the distillation column, the second intermediate point being above the first intermediate point.

Cold Box (Method for producing carbon monoxide)

A method for producing carbon monoxide by cryogenic distillation comprising the following steps: a) a gas mixture containing carbon monoxide, hydrogen and nitrogen is cooled and partially condensed to produce a cooled and partially condensed gas mixture; b) the cooled and partially condensed gas mixture is separated to produce a hydrogen-enriched gas and a carbon monoxide-enriched liquid; c) a stream of the carbon monoxide-enriched liquid is sent to a stripping column to produce hydrogen-free liquid carbon monoxide and hydrogen-enriched carbon monoxide gas; d) a stream of the hydrogen-free carbon monoxide is sent to a first intermediate level of a distillation column; e) a liquid stream, richer in methane compared to the stream feeding to the distillation column, is withdrawn from the bottom of the distillation column; f) a carbon monoxide-rich stream is withdrawn from a second intermediate point, the second intermediate point being above the first intermediate point; and g) a stream, enriched with nitrogen and optionally hydrogen compared to the stream feeding to the distillation column, is withdrawn from the top of the distillation column.

Steam Reformer for Carbonmonoxide plant

Steam reforming of hydrocarbons is a well-established process for the generation of synthesis gas, hydrogen etc. The steam reforming process comprises the high temperature reaction of methane or higher hydrocarbons over a catalyst to produce hydrogen and carbon monoxide in accordance with the following reaction equation:
CnH2n+2 + nH2O nCO + (2n +1)H2
The reforming takes place in tubes packed with catalyst and arranged vertically in gas-fired steam reformers. A nickel catalyst is used and applied to a supporting structure. The operating conditions of the steam reformer vary depending on the application, with temperatures ranging from 740 °C to 950 °C and pressures of up to 50 bar. This wide range of operating conditions necessitates a versatile reformer design.
