Methanol production is a CO 2 -intensive process as its raw materials are mainly from fossil resources. Despite numerous proposed measures for CO 2 mitigation, selecting low-carbon options for methanol production still poses significant challenges. Here, we present an assessment approach based on their fossil energy demand (FED) and global warming potential (GWP). Specifically, four methanol production routes were first established based on the calcium looping sorption enhancement process, namely, coal to methanol, natural gas to methanol, biomass to methanol, and biomass to methanol with biochar (BTMC). Results show that appealing performances for FED and GWP of −17.085 MJ/kg-methanol and −2.457 kg-CO 2 -eq/kg-methanol were achieved in the BTMC process. Additionally, by tracking FED and GWP indicators, the lowest carbon footprint route (−5.793 kg-CO 2 -eq/kg-methanol) can be quickly identified when considering CO 2 capture, renewable energy, and feedstock substitution for existing processes. Overall, this work provides a new pathway for sustainable methanol production by evaluating low-carbon options from both energy and environmental perspective.

The industrial anthropogenic emissions of the greenhouse gas, carbon dioxide (CO2) have surged over the past century. The unconscious emission of carbon dioxide into the environment leads to the greenhouse effect and causes global warming. The cement industry is regarded as one of the major sources of carbon dioxide emissions recently, numerous companies decide to construct relevant installations for mitigating the severe pollution caused by CO2. HeidelbergCement, a multinational building materials company, is also conscious of the issue and concentrates on the capture, usage, and storage of CO2 (CCUS). Apart from the direct use, the captured CO2 has the possibility to become a promising business. In the paper, one of the technologies that convert CO2 into methanol by hydrogenation is presented and simulated with the program named Aspen Plus. The improvements based on the purer output and energy saving on the initial simulation were accomplished. After purifying the solution, there is a rise in the concentration of CH3OH from 96.0%wt to 99.97%wt, which is an exceptionally high level that could be employed for spectroscopic or semiconductor applications. This paper may offer some references for the future studies of CCUS.

“…This indicates a low conversion rate for the process, with a signify cant amount of reactants still present in the gas stream exiting the reactor. Research studies have indicated that the average hydrogen conversion rate does not exceed 50% (Timsina et al 2022). Consequently, it is necessary to recover the unconverted syngas for reintegration into the synthesis loop.…”

The aim of this study was to design a simple and user-friendly model for simulating the adiabatic multiphase fixed-bed reactor utilized in methanol synthesis at the Methanol and Synthetic Resins Complex in Arzew, Algeria. The process was based on the ICI (Imperial Chemical Industries) method, employing a copper oxide-based catalyst (CuO, ZnO, or Al2O3). Methanol is synthesized from syngas, which is a mixture of CO, CO2, and H2, and acts as the primary feedstock for methanol production in this reactor setup.The developed model provides the capability to predict methanol yield, control high temperatures resulting from exothermic reactions within each catalyst bed, and determine the necessary amount of quenching gas injection to reduce the temperature. Through simulations, we achieved a crude methanol ratio of 3.41, closely matching the estimated ratio of 3.4 in the actual reactor. This outcome serves as strong evidence for the effectiveness of the designed model in simulating complex chemical reactors.Building on these promising results, the study proceeded to the recycling simulation stage, where the mass of crude methanol was increased to 4.1%. This step indicates the model's capacity to handle and optimize the recycling process, which is crucial for enhancing the overall efficiency and sustainability of methanol production in the complex. By accurately predicting process parameters and performance, the developed model proves to be a valuable tool for advancing methanol synthesis technologies and promoting more efficient industrial practices.
