For a plant comprising a gas/air separation unit supplying a boiler and a boiler-fed unit for compression and/or purification of CO2, the quantity of fumes sent to the compression and/or purification unit is modified according to the sale price of the electricity generated and/or the cost of venting the fumes.
摘要:
The present invention relates to a process and apparatus for producing a fluid enriched in carbon dioxide starting from a waste gas from a ferrous metallurgy unit.
摘要:
The invention relates to an apparatus for producing carbon dioxide-rich liquid, which includes a separation unit including a column for physically washing with a solvent and means for cooling a fluid of the separation unit, and a unit for compressing and liquefying a carbon dioxide-rich gas derived from the separation unit, including means for cooling the gas upstream and/or downstream from the compression operation, a single refrigerating cycle using carbon dioxide as the refrigerant, which is suitable for providing frigories to the means for cooling the fluid of the separation unit and to the means for cooling the gas upstream and/or downstream from the compression operation, and means for sending a portion of the liquid from the liquefaction unit to the refrigerating cycle.

摘要:
Integrated air separation units with a petrochemical process. This invention provides an integrated process and gas treatment process wherein at least one first pressurized gas derived from a first process at a first site is expanded. Using the work generated by the expansion of at least one pressurized gas, a first gas compressor at the first site is driven, operates, and removes compressed gas from the first gas compressor. At least part of the compressed gas from the first gas compressor is sent to a gas treatment unit located at a remote second site. At least part of the compressed gas sent from the first site to the second site is treated in the gas treatment unit. At least one fluid from the gas treatment unit is removed and at least part of the fluid removed from the gas treatment unit is sent to the first site.

摘要:
In a process-for the use of a hydrocarbon feedstock (10) by reacting the feedstock in a reactor (11) with oxygen (9) to form a synthesis gas containing at least carbon monoxide, carbon dioxide and hydrogen and subjecting the synthesis gas to a conversion process comprising an exothermic reaction to produce methanol as a final product in a converter (15), the converter operating at an operating pressure, said oxygen being provided to the reactor at an oxygen pressure, the synthesis gas is produced at a pressure higher than the operating pressure of the converter.
