The invention relates to a combined reforming process for making synthesis gas from a desulphurized gaseous hydrocarbon feedstock, wherein the feedstock is split into a first and a second feedstock stream, the first feedstock stream is mixed with steam and fed to a gas heated reformer (GHR) and a steam methane reformer (SMR) operated in series, and the second feedstock stream is mixed with reformed gas coming from the SMR and fed with oxygen to a non-catalytic partial oxidation reformer (POX). The process of the invention enables to produce syngas with adjustable composition and at very high capacity in a single line. The process specifically allows designing a methane-to-methanol production plant with a capacity exceeding 10000 mtpd using technically and economically feasible reforming equipment, and showing high feedstock and energy efficiency. The invention further relates to an integrated process for making methanol from a hydrocarbon feedstock comprising said combined reforming process.

Combined reforming process for methanol production

An apparatus for performing continuous flow chemical reactions such as oxidation, oxidative dehydrogenation and partial oxidation processes involving a reactor design characterized by controlled/optimized addition of a reactant with the objective of: (i) avoiding the explosion regime of the reactant mixture (e.g., hydrocarbon/oxidant mixture); (ii) maximizing the selectivity of the reaction to the desired product; (iii) limiting the reactor temperature gradient and therefore the threat of reaction runaway; and (iv) controlling the operating temperature of the reaction zone so that desirable temperature range is maintained over the entire zone.
