Methanol Manufacture from Natural Gas

Methanol (methyl alcohol) is an important chemical commonly used as a solvent, as a starting material in the production of chemicals and in the fuels sector. In recent years, technologies that have developed using methanol as the main raw material include methanol-to-gasoline (MTG), methanol-to-olefins (MTO) and methanol-to-propylene (MTP) processes.

Technology Description

The following describes a process for producing methanol from natural gas that employs combined reforming for the generation of synthesis gas (syngas). Companies offering combined reforming technologies similar to the one discussed here include: Air Liquide Global E&C Solutions; Toyo Engineering Corp.; KBR Inc.; Johnson Matthey and Haldor Topsoe A/S.

Syngas Generation

Natural gas feedstock passes through a desulfurization step and is then fed to a saturator, where process water is supplied until gas saturation is achieved. The saturated natural gas is then sent to a pre-reformer for converting the larger hydrocarbons in the feed gas into a gas rich in methane and hydrogen. The pre-reformed gas is split into two streams: a portion is fed to the steam-reformer, with the balance being fed directly to the autothermal reformer (ATR).

In the steam reformer, methane reacts catalytically with steam, generating CO and H2. In the ATR, methane is converted to CO and H2 using oxygen as the reforming agent. The ATR outlet stream is then cooled and the condensed water is separated from the syngas.
