“…In the process simulation, two reactors were employed due to low conversion of the CO 2 hydrogenation reaction. represents the process flow diagram of methanol production via CO 2 hydrogenation (Wiesberg et al, 2016). In this process, the feed of 1,000 kmoles per hour of carbon dioxide at 40 • C and 20 bar was mixed with the 3,000 kmoles per hour of hydrogen (at the same conditions).…”

Carbon dioxide (CO 2) is one of greenhouse gases, which can cause global warming. One of studies to mitigate CO 2 emissions to the atmosphere is to convert CO 2 to valuable products (i.e., methanol). To make methanol production via CO 2 hydrogenation a competitive process, the optimal operating conditions with minimum production cost need to be considered. This paper studied an application of response surface methodology (RSM) in optimization of methanol production via CO 2 hydrogenation. The objective of this optimization was to minimize the methanol production cost per tons produced methanol. The sensitivity analysis was performed to determine the parameters that show significant impacts on the methanol production cost. Response surface methodology coupled with non-linear programming solver were used as the optimization tool. The results showed RSM was successfully applied to the methanol production via CO 2 hydrogenation process. The obtained minimum methanol production cost was $565.54 per ton produced methanol with the optimal operating conditions as follows. Inlet pressure to the first reactor: 57.8 bar, Inlet temperature to the first reactor: 183.6 • C, Inlet pressure to the second reactor: 102.6 bar, Outlet temperature of the liquid stream cooler after the second reactor: 63.5 • C, Inlet temperature to the first distillation column: 51.8 • C.

“…Whilst state‐of‐the‐art processes produce methanol almost exclusively from fossil fuels, there is an ever increasing interest in producing methanol based on alternative syngas sources. In such cases CO 2 and CO are obtained from industrial waste streams such as biogas plants, cement or steel production , , or carbon capture from air . H 2 can be supplied from carbon‐neutral sources, e.g., via electrolysis of water (H 2 O).…”

Worldwide production capacities of carbon‐based chemicals and associated products are steadily increasing. At the same time the reduction of greenhouse gas emissions such as carbon dioxide is of paramount importance in order to mitigate the anthropogenic impact of climate change. In Carbon2Chem® a cross industrial network develops concepts towards the utilization of steel mill gases for the sustainable production of “green” base chemicals, including methanol. This Review describes the technological challenges emerging from the use of these alternative feedstocks, specifically in the context of methanol production processes.

“…On the use of CO 2 as a raw material for methanol synthesis, Wiseberg et al [19] compared the direct methanol production process via the hydrogenation of CO 2 and the bi-reforming (steam reforming plus dry reforming) of natural gas process. The study concluded that the direct hydrogenation process is economically viable if the hydrogen price is lower than 1000 USD/t but the bi-reforming process is not feasible.…”

Carbon dioxide recycling is one of the possible contributions to CO2 mitigation and provides an opportunity to use a low-cost carbon source. Methanol is a commodity chemical that serves as an important basic chemical and energy feedstock with growing demand. For each of the four types of industrial methanol production processes from natural gas (methane), i.e., steam reforming (SR), autothermal reforming (ATR), combined reforming (CR), and two-step reforming (TSR), CO2 utilization cases of (A) no utilization, (B) as reforming step feedstock, and (C) as methanol synthesis step feedstock were designed based on common industrial operation conditions and analyzed for energy consumption, exergy loss (EXloss), net CO2 reduction (NCR) and internal rate of return (IRR). The utilization of CO2 can reduce energy consumption. The processes with the lowest and the highest EXloss are SR and ATR, respectively. All SR processes give negative NCR. All the B-type processes are positive in NCR except B-SR. The highest NCR is obtained from the B-ATR process with a value of 0.23 kg CO2/kg methanol. All the processes are profitable with positive IRR results and the highest IRR of 41% can be obtained from B-ATR. The utilization of CO2 in the industrial methanol process can realize substantial carbon reduction and is beneficial to process economics.
