  • Efficient Way of Carbon Dioxide Utilization in a Gas-to-Methanol Process: From Fundamental Research to Industrial Demonstration
    Topics in Catalysis, 2018
    Co-Authors: Chundong Zhang, Geunjae Kwak, Haegu Park
    Abstract:

    Efficient Utilization of CO_2 to produce clean liquid fuels and various petrochemicals has attracted significant attention during the past decades. This review mainly focuses on our efforts and main achievements during the development of a CO_2-utilizing Gas-to-Methanol (CGTM) process, which is composed of CO_2/steam-mixed reforming and methanol synthesis via CO_2 and CO hydrogenation. Experimental apparatus at different scales, ranging from lab to demonstration, have been established to pursue an efficient CGTM process with enhanced energy efficiency and reduced CO_2 emissions. The proposed CGTM process employs a proprietary coke-resistant Ni-based catalyst in the reforming section, which is very stable under a 1000-h accelerated stability test. Based on the results of the process simulation and optimization obtained by using Aspen Plus, a CGTM demonstration plant with a methanol-production capacity of 10 t/day is designed and constructed, which comprises a reforming section (co-feeding CO_2 into the reformer), a methanol synthesis section, and a recycling section. During the continuous operation for 1000 h, the CGTM demonstration plant exhibited a satisfactory performance, which is in good agreement with the design values. The overall thermal efficiency is shown to be superior to that of the conventional Gas-to-Methanol (GTM) processes, and the CGTM process is economically feasible given that the NG price, methanol price, and the plant scale are located in the following range of 1–5 $/MMBTU, 350–500 $/Mt, and 2500–5000 TPD, respectively. Furthermore, the proposed CGTM process would be even more competitive in the case of a higher Carbon tax.

    Co-Authors: Chundong Zhang, Kiwon Jun, Ruxing Gao, Geunjae Kwak, Haegu Park
    Abstract:

    Abstract Conceptual design for two options of Carbon-Dioxide-utilized gas-to-methanol process (CGTM) was implemented by using process simulation software Aspen Plus. The overall mass and energy stream results as well as the thermal and Carbon efficiency were obtained from the developed process models. Before the following economic evaluation and sensitivity analysis, total capital investment (TCI) and total product cost (TPC) of both CGTM options were determined. Then, economic evaluation were conducted to assess the economic profitability of the base cases for both CGTM options, using the economic evaluation indicators such as net present value (NPV), internal rate of return (IRR), and discounted payback period (DPBP). Furthermore, sensitivity analysis as well as break-even analysis were also applied to investigate the economic performance of both CGTM options under different circumstances, by changing parameters such as methanol and NG prices, plant scale, and Carbon tax. It was shown that the methanol price, CAPEX, and NG price are the most sensitive factors, and the two CGTM options were economically feasible in the plant scale range of 2500–5000 ton per day, according to the economic evaluation indicators NPV, IRR, and DPBP, and were more economically competitive in the case of higher plant scale and Carbon tax.
