USING ORGANIC WASTE AS RAW MATERIAL IN METHANOL PROCESS
Methanol is produced from synthesis gas, which is produced from natural gas. Natural gas can be replaced by biogas for the production of synthesis gas. We compare the production of methanol from varieties of raw materials -natural gas and biogas. The basic starting point for comparison is the same mass inlet flow rate of both raw materials under the same operating conditions. Methanol production using natural gas and biogas as the raw material was simulated using an Aspen Plus simulator with real chemical thermodynamic, and 16 146 kg/h crude methanol from natural gas and 14 615 kg/h from biogas could be produced. Methanol production from biogas could also increase by 9.7 ％ with processed operational and parametric modification using nonlinear programming (NLP). The most important is the conversion of methane in the reformer. Optimal methane conversion could take place by operating with the use of optimal parametric data in a reformer unit (temperature=840 ℃ and pressure=8 bar). The optimal production of methanol from biogas was 16 040 kg/h under optimal parameters.
