A comparative techno-economic analysis of combined oil and power production from pyrolysis and co-pyrolysis plants utilizing rice straw and scrap rubber tires

Viable Alternative Prospective Option for Liquid Methanol Industry’s Long-Term and Cost-Effective Development: CO2 to Methanol Conversion and Ethylene Glycol Coproduction

“…Here, the total production costs (TPC) of different CO 2 synthesis methanol technologies were evaluated to compare the economic performances of different methanol synthesis processes. The formulas are shown as follows: − T P C = ∑ k T C R k + prefix∑ k C O M k − prefix∑ k C k m MeOH T C R k = T C I k × C R F C R F = r 1 − false( 1 + r false) − n where TCR k is the total investment required for unit k ; COM k is the annual operation and maintenance cost of unit k ; C k is the salvage value of unit k (4%); m MeOH is the methanol flow rate; CRF is the capital recovery factor; and r and n are, respectively, the depreciation rate (12%) and the life time of the plant (15%). Raw material costs (CR), utility costs (CU), and operation and maintenance costs ( CM ) were calculated based on data in the Supporting Information.…”
