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.

In Fig. 1, the box diagram for the methanol production via natural gas reforming along with direct hydrogenation of CO 2 captured from the power plant flue gas is shown, which is the proposed process in this study. Six operating steps are considered for this purpose: 1) Capturing CO 2 from the flue gas.. 2) Steammethane (natural gas) reforming. 3) Compression of CO 2.

HOW THE STEAM REFORMING REACTION TAKES PLACE The gases required to make Methanol later in the process leaves the Steam Reformer and the mixture is simply called Reformed Gas. The reformed gas contains a lot of unreformed steam at this stage, however this will be cooled, condensed into water and removed.

Process Chemistry. Catalytic conversion of hydrogen (H 2) and carbon monoxide (CO) from coalderived syngas into methanol can be done with conventional gasphase processes, or with a liquid phase methanol (LPMEOH™) process developed by Air Products and Chemicals. The reactions of interest are: 2 H 2 + CO → CH 3 OH. CO 2 + 3 H 2 → CH 3 OH ...
