Co-electrolysis for power-to-methanol applications
Andika, Riezqa,Nandiyanto, Asep Bayu Dani,Putra, Zulfan Adi,Bilad, Muhammad Roil,Kim, Young,Yun, Choa Mun,Lee, Moonyong Elsevier 2018 RENEWABLE & SUSTAINABLE ENERGY REVIEWS Vol.95 No.-
<P><B>Abstract</B></P> <P>This article reviews the issues facing co-electrolysis and its applications to the power-to-methanol process. Co-electrolysis is an attractive process for syngas production that uses excess generated electricity. In extended applications, syngas produced from co-electrolysis can be used for various applications like methanol production. In this review, the power-to-methanol process is comprehensively discussed from a process systems engineering viewpoint. The subjects discussed include the reason to choose methanol as a final product, the latest progress in power-to-methanol projects, and a comparison of methanol production from H<SUB>2</SUB>-CO (from co-electrolysis) and H<SUB>2</SUB>-CO<SUB>2</SUB> mixtures (from electrolysis). Syngas production pathways from co-electrolysis and electrolysis are further investigated, and potential power-to-methanol schemes using co-electrolysis are deployed. Lastly, research directions are proposed to accelerate power-to-methanol commercialization.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Power-to-methanol (PtM) technology using co-electrolysis is intensively reviewed. </LI> <LI> The PtM technology regulates fluctuate power supply from renewable energy and consumer demand. </LI> <LI> Co-electrolysis applications for PtM process are comprehensively discussed. </LI> <LI> A comparison of methanol productions from co-electrolysis and from electrolysis is done. </LI> <LI> Start-up time and ramping flexibility are critical to commercialize the PtM process. </LI> </UL> </P>

We conducted research to evaluate economically and engineering about the synthesis of Magnesium Oxide, MgO, nanoparticles using physicochemical methods. The method used was economic evaluation by calculating GPM, BEP, PBP, and CNPV. The other method used was engineering perspective. MgO nanoparticles were synthesized by reacting Mg(NO3)2 and NaOH with a mole ratio 1: 2. Mg(OH)2 formed was heated and calcined to remove water content and to oxidation to form MgO. An economic evaluation by calculating GPM and CNPV for the production of MgO nanoparticles on an industrial scale shows that the payback period (PBP) occur in the third year and profits increase each year. Tax variations show that the higher of tax, the lower profits received. When there was an increase of selling prices, the profit was greater. The variable cost used is the price of raw material. When there was an increased in the variable cost price, the payback period was longer and the profits was reduced. The benefit of this research is knowing the industrial production of MgO nanoparticles is beneficial. The function of MgO nanoparticles is a material for the manufacture of ceramics and can be used as an antimicrobial in the water filtration process.

Economic Evaluation on Production of ZnO Nanoparticles from Laboratory Scale to Industrial Scale
Tri Suhartono,Asep Bayu Dani Nandiyanto ASCONS 2019 INTERNATIONAL JOURNAL OF EMERGING MULTIDISCIPLINAR Vol.3 No.4
ZnO nanoparticles are used to obtain inorganic antibacterial and UV-blocking properties. The purpose of this study is to evaluate the increase in the production of ZnO nanoparticles from the laboratory scale to the industrial scale. Economic evaluation is carried out from an engineering and economic perspective. From the engineering evaluation, the results show that the production of prospective ZnO nanoparticles uses modern methods and technology. From an economic point of view, the results show that the production of ZnO nanoparticles on an industrial scale can benefit from certain conditions of raw materials, certain conditions of selling prices, and certain conditions of income tax. All evaluation parameters give a positive price. The development of this project needs to be added especially regarding additional strategies to increase profits and to attract investors, this study provides sufficient promise for the production of ZnO nanoparticles in developing countries.
