MCE offers cost-effective, modular methanol production units using compact Steam Methane Reformers. The process scheme consists of following sections:
Feed gas is compressed and treated to remove natural gas liquids, water and acid gases. Hydrogenator and Sulfur removal beds are used to remove traces of sulfur prior to reforming. The Hydrogen rich gas recycled from Methanol synthesis loop is used for hydrogenation of sulfur compounds.
The two-step reforming process features a combination of tubular reforming (primary reforming) followed by oxygen-fired adiabatic reforming (secondary reforming). This technology can be used for large and small-scale plants and offers several advantages compared to conventional steam reforming indicated below:
The methanol synthesis step involves conversion of synthesis gas into raw methanol, a mixture of methanol, small amount of water, dissolved gases and traces of by-products (DME, higher alcohols, other oxygenates and minor amounts of acids and aldehydes). The methanol synthesis catalyst and process are highly selective in nature. The conversion of hydrogen and carbon oxides to methanol is described by the following reactions:
CO2 + 3H2 → CH3OH + H2O
CO + 2H2 → CH3OH
Distillation as well as Molecular Sieve options are available for purification of Methanol
MCE also supplies factory assembled containerized units for production 25/ 50/ 100 TPD Methanol.
