Abstract
This study focuses on the design of a plant for the production of 30,000 tons per year of dimethyl carbonate (DMC) from natural gas. The plant design was carried out using the Aspen HYSYS Software. The data obtained from Kokori natural gas served as the primary feedstock for the plant. A kinetic model for the production of DMC was developed from existing literature, followed by the development of the mathematical model of a packed bed reactor. The simulation of the DMC plant model was done using Aspen HYSYS software. DMC is a widely utilized liquid chemical with diverse applications ranging from transportation fuel and energy. The planned DMC production plant was designed to employ the methanol dehydration method for synthesizing 30,000 metric tons of DMC annually. The primary feedstock used in the process is natural gas. Methanol is synthesized from natural gas, and then DMC is produced from the dehydration of methanol in the second step. The methodology involves the compression of natural gas to extract methane, followed by dry reforming to produce syngas, methanol synthesis, and subsequent conversion to DMC. For the simulation of DMC production from natural gas in this study, a flow rate of 3847 kg/h of natural gas (feed) was supplied with a temperature and pressure of 30°C and 10 bar, respectively, at the plug flow reactor (PFR). The DMC was produced at the conversion reactor where methanol and carbon dioxide (CO2) were synthesized at a temperature and pressure of 162.7oC and 60 bar, respectively. The DMC production was optimized at a methanol conversion rate of 80% to yield DMC. Material and Energy balance, development of models, and sizing of major equipment of the plant were considered. For the cost estimation and economic evaluation for the first year, an estimated capital investment of approximately 2,823,220 USD and an operating cost of 1,506,050 USD/year will be required. The establishment of the plant is anticipated to yield encompassing job creation, increased tax revenue, and local economic development. Overall, the proposed project plant holds significant potential and annually produces 30,000 t of 95% pure DMC from natural gas.
