    Abstract: A method for the production of syngas from methanol feedstock is disclosed. The methanol feed (110) is supplied to a partial oxidation reactor (112) with oxygen (114) and optionally steam (116) to yield a mixed stream (118) of hydrogen, carbon monoxide, and carbon dioxide. The carbon dioxide (122) is separated out and the hydrogen and carbon monoxide mixture (124) is fed to a cold box (126) where it is separated into hydrogen-rich and carbon monoxide-rich streams (130, 128). The separated carbon dioxide (122) can be recycled back to the partial oxidation reactor (112) as a temperature moderator if desired. The carbon monoxide-rich stream (128) can be reacted with methanol (134) in an acetic acid synthesis unit (132) by a conventional process to produce acetic acid (136) or an acetic acid precursor. Optionally, an ammonia synthesis unit (144) and/or vinyl acetate monomer synthesis unit (156) can be integrated into the plant.

    Abstract: A process for the recovery of oil from a subsurface reservoir in combination with the production of liquid hydrocarbons from a hydrocarbonaceous stream involving: (i) separating an oxygen/nitrogen mixture into a stream enriched in oxygen and an oxygen depleted stream; (ii) partial oxidation of the hydrocarbonaceous feed at elevated temperature and pressure using enriched oxygen produced in step (i) to produce synthesis gas; (iii) converting synthesis gas obtained in step (ii) into liquid hydrocarbons; and (iv) recovering oil from a subsurface reservoir using at least part of the oxygen depleted gas stream produced in step (i).

    Abstract: In a process for separating air in a system comprising a gas turbine, including a compressor (1), a combustor (5) and an expander (17), said expander being coupled to the compressor, a natural gas conversion unit (23) and an air separation unit (20), air is compressed in the compressor, a first part (3) of the air is sent to the combustor and a second part (7) of the air is sent to the air separation unit, oxygen enriched gas (21) is sent from the air separation unit to the natural gas conversion unit, compressed nitrogen enriched gas (16) is sent upstream of the expander, a first stream (33) of natural gas is sent to the natural gas conversion unit, a second stream of natural gas (35) is sent to a natural gas liquefaction unit and work produced by the expander is used to operate a cycle compressor of a refrigeration cycle of the natural gas liquefaction unit.
