Abstract: Process and plant for producing a synthesis gas by catalytic steam reforming of a hydrocarbon feedstock in a steam reforming unit, further comprising a first and second shift conversion unit, wherein water is removed from the synthesis gas as a process condensate, wherein boiler feed water is introduced in the process, and wherein said process or plant produces at least two separate steam streams: a pure steam which is generated from at least a portion of said boiler feed water by the cooling of synthesis gas, and a process steam which is generated by evaporating at least a portion of the process condensate in a process condensate boiler (PC-boiler) by using synthesis gas, optionally together with pure steam and/or flue gas from the steam reforming unit. Process steam, and pure steam other than that from the PC boiler, are added to the first shift conversion unit, optionally also to the second second shift conversion unit.

Abstract: An apparatus and process for distillation of methanol which may also be used in distillation of other products, such as ethanol. The apparatus and process have the purpose of reducing the consumption of energy and of cooling water and/or electricity in a distillation process of crude intermediate products, including a pre-treatment stage, known as stabilizing stage, for the removal of the volatile components, and a concentration stage, including one or more columns for distillation.

Abstract: A process and plant for producing a high purity CO2 product, comprising: providing a CO2-rich stream containing hydrocarbons, hydrogen and/or CO, combining it with a stream rich in methane (CH4), and mixing it with oxygen, thereby forming a CO2/O2- mixture; subjecting the CO2/O2- mixture to a catalytic oxidation step, thereby producing a purified stream having a higher CO2 and/or H2O concentration; removing H2O from said purified stream, for producing said high purity CO2 product stream. The CO2-rich stream is for instance derived from the CO2-removal section of a plant for producing hydrogen.
