Description
Summary:•Refine bleaching deodorized palm oil (RBDPO) is used for the bio-hydrogenated diesel (BHD) production process.•Gaseous byproducts from BHD process are raw material for methanol synthesis, valuable co-product.•The comparison of stand-alone BHD process and BHD process coupled with methanol synthesis based on technical and economic aspect.•The BHD process couple with methanol synthesis performs the best option. A bio-hydrogenated diesel (BHD) or green diesel is produced from refined bleached deodorized palm oil (RBDPO) via a heterogeneous catalytic reaction which requires high hydrogen to oil volumetric ratio for a complete conversion of oil. In this regard, a hydrogen recovery process is required to reduce a high amount of hydrogen loss in a gas by-product. This work proposes coupling the conventional BHD process with a production of methanol, a valuable co-product, and performs its techno-economic evaluation in comparison with the stand-alone BHD process. The results showed that the BHD process coupled with the methanol synthesis can recover by 46.3% of discharged hydrogen and reduce 14% of carbon dioxide and carbon monoxide emissions from the production process. Furthermore, methanol synthesis could improve the internal rate of return (IRR) by 23.2%, shorten the payback period by 2.81 years, and increase the net present value (NPV) by 54.41 million USD relative to the BHD process. Finally, environment potential impact of both processes are analyzed. The most significant on the environment is hydro-processing stage and both processes provide same environmental results.
