Abstract The availability of natural gas as feedstock for nitrogen fertilizer production continues to decline, while its price increases, encouraging the search renewable feedstocks future green urea industry. Renewable include waste biomass, hydrogen from solar PV ‐electrolysis, and combination these with gas. selection a strategy is critical step in trade‐off between economic environmental considerations. aim this work was propose using multi‐objective optimization ( MOO ) model minimize...
Abstract Bioenergy with carbon capture and storage (BECCS) has the potential to produce negative emissions. This study assessed overall energy efficiency dioxide (CO 2 ) avoidance costs emission footprint following integration of BECCS a polygeneration system (BECCS-PS) for co-production green electricity methanol. The process was simulated in Aspen Plus HYSYS v.11. Oil palm empty fruit bunches were used as feed biomass integrated gasification combined cycle power plant. flue gas, which...
This study evaluates three pathways: supercritical water treatment (SCW), CO2-water (scCO2-H2O), and catalytic hydrothermal hydrolysis (CHH) to produce second-generation bioethanol using palm tree fronds (PTF) as feedstock. The analysis focuses on technical performances process simulation with Aspen Plus™, environmental evaluation by applying a Life Cycle Assessment (LCA) framework an economic the levelized cost. results of reveal CHH best pathway for production, highest ethanol yield at 273...
Crude oil logistics activities, which are mostly carried out using ships, one of the contributors to greenhouse gas (GHG) emissions. GHG emissions from activities predicted increase significantly by 2050, so they need be controlled with right planning strategy. This study aims apply green concept in crude transportation that considers multiple depots and heterogeneous fleets multi-objective optimization (MOO). investigates a case refinery unit 6 scenarios single-objective (SOO) MOO cases....
Abstract This study proposes a conceptual design of green hydrogen production via proton exchange membrane electrolysis powered by floating solar photovoltaic system. The system contributes to industrial decarbonization in which blending with natural gas is proposed as an approach smooth the energy transition. addresses challenge supplying continuous flow-rate hydrogen, typically demanded end users. particularly considers realistic area required for installation To enable 7.5 million...
Sebira Island is an Indonesian remote island that relies on its energy source mostly from diesel-generated electricity. The island's main economic activities include related to the coastal and fishery sectors. This research paper evaluates long-term planning of a mini-grid hybrid system solar, wind, diesel in level based technical aspects. designed not only meet electricity demands residential, community, but also integrated with development productive zone advance local economy by enhancing...
Herein, Ag/TiO2 nanocomposite was synthesized via a green chemistry approach, which is an eco-friendly, simple, and cost-effective method involving mangosteen pericarp extract as reducing agent. The as-prepared nanocomposites were characterized using X-ray powder diffraction (XRD), Fourier transformation infrared spectroscopy (FT-IR), UV-Vis spectrophotometer, Scanning electron microscopy (SEM), Energy dispersive (EDS), Transmission (TEM), Zeta potential measurement, nitrogen (N2)...
The transportation sector is one of the largest fuel consumers and pollutant contributors worldwide. International Maritime Organization predicts that greenhouse gas (GHG) emissions from will be increasing significantly until 2050, driven by growth in global maritime trade. Managing logistics distribution routes considered a possible approach for controlling GHG emissions. This study aims to implement green concept petroleum products—gasoline, kerosene, diesel—in eastern Indonesia, whose...
This study is to obtain the effect of adding hydrochloric acid (HCl) mixture sulfuric (H2SO4) and HNO3 in CNT covalent functionalization. HCl expected increase dispersibility functionalized by improving dispersion time period done with H2SO4 or HNO3. Functionalization used volume ratio 3:1. Covalent functionalization 0.5 grams MWCNT ultra sonicated 50mL Additions 200 mL variation molarity from 1M, 2M, 3M, 4M, 5M 6M. were oxidized form carboxylic hydroxyl bonds on surface that CNT.
