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.

Methanol is predominantly produced by a coaltomethanol process in China. However, this process is criticized by high CO 2 emissions because of the high carbon contents of coal. The high CO 2 emission and low resource utilization efficiency greatly weaken the competitiveness of the coalto methanol industry.

Methanol is a clean fuel and an important feedstock for the petrochemical industry. Conventionally, the coaltomethanol process generates a substantial amount of CO2 emissions with a low yield of methanol. In this study, we propose the conceptual design development of coaltomethanol process using captured CO2 from the gasification plant by implying process intensification. The base case and ...

Overall, the coaltomethanol process has the greatest demand for green hydrogen. However, the uncertainty of hydrogen flowrate has a great impact on the system, and the highvalue utilization is also limited by the lowgrade waste heat at a relatively low temperature. The coaltoSNG process shows the smallest demand for green hydrogen.

Gasification is a thermochemical process for the conversion of a solid organic material, typically coal or biomass, into syngas. From a chemical point of view, gasification occurs due to the partial oxidation of a solid material at temperatures of 700900 °C by means of a gasifyingoxidant agent, such as air, oxygen, steam or carbon dioxide.
