Combined reforming process for methanol production |
摘要 |
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. |

1. A combined reforming process for making a synthesis gas mixture from a desulphurised gaseous hydrocarbon feedstock, wherein the feedstock is divided 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),
wherein said synthesis gas mixture produces methanol and wherein the combined reforming process produces at least 10,000 metric tons of methanol per day. |
