Energies 2020, 13, 6421 3 of 21 with the methanol synthesis process. VanDal et al. [18] designed and simulated the conversion of CO2 and H2 to methanol using Aspen Plus. They proposed to capture CO2 from a coal fired power plant and produce H2 from the water electrolysis. Their results showed that ton of CO2 can be abated per ton of methanol production.

The process flow of Route 3 is similar to that of Route 1 . Route 3 uses a coelectrolysis unit and a MeOHsynthesis unit. In the coelectrolysis unit, steam and CO 2 are reduced to syngas by the SOEC after pressurization (up to ~ MPa). The syngas is then sent to the methanolsynthesis unit and converted to MeOH.

A coalbased coproduction process of liquefied natural gas (LNG) and methanol (CTLNGM) is developed and key units are simulated in this paper. The goal is to find improvements of the lowearning coal to synthesis natural gas (CTSNG) process using the same raw material but producing a lowmargin, single synthesis natural gas (SNG) product. In the CTLNGM process, there are two innovative aspects.

The coaltomethanol (CTM) is an important technical route for methanol process suffers from high CO 2 emission and low energy efficiency due to the mismatch of H/C (hydrogentocarbon) ratio between raw coal and products. Hydrogen production from renewable energy can be introduced into the system to meet the H/C ratio. In this paper, a novel CTM process with nearzero carbon ...

The methanol capacity of the CTM and GHCTM processes is approximately Mt/y with the same coal consumption at Mt/y. The schematic diagram and life cycle boundary of the CTM and GHCTM processes are displayed in Fig. 1, which expands the research scope from the methanol production process to the whole lifetime ("cradle to gate") of the methanol production plant.
