KOMBINIERTES REFORMIERUNGSVERFAHREN FÜR DIE METHANOLHERSTELLUNG

摘要

The invention relates to a combined reforming process for making a synthesis gas mixture from a desulphurised methane-rich gaseous feedstock, wherein the gaseous feedstock is mixed with steam and passed through an adiabatic pre-reformer (APR) (6), and wherein pre-reformed gas from the APR is divided into three streams that are fed to a steam methane reformer (SMR) (21), a gas heated reformer (GHR) (18) and to an auto- thermal reformer (ATR) (14), which reforming reactors are operated in parallel. 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 of at least 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 methane-rich gaseous feedstock comprising said combined reforming process.
