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....
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...
Abstract Multi-objective optimization is one of the most effective tools for decision support system. This study aims to optimize gasification municipal solid waste (MSW) advanced power plant. MSW gasifier simulated using Aspen Plus v11 produce syngas, be fed into generation technologies. Four technologies are selected, oxide fuel cell, gas turbine, engine, and steam turbine. Mixed-integer non-linear programming (MINLP) multi-objective developed provide an optimal solution minimum levelized...
Indonesia's energy consumption mostly comes from non-renewable sources, with 32% dedicated to the transportation sector. The Indonesian government is currently increasing application of a 30% biodiesel blend in diesel fuel and aiming for 20% bioethanol gasoline by 2025. Microalgae one most promising sources production, yielding ethanol glycerol as by-products. main processes this plant are cultivation, transesterification, washing, side product. For bioethanol, include hydrolysis,...
Abstract The trend towards increasing biofuel blending mandates in several countries has raised a sustainability trilemma, especially for biofuels derived from palm oil. This study aims to find the most sustainable hydrogen production technology of hydrogenated vegetable oil (HVO) and blending. It assesses palm‐oil‐derived biodiesel (FAME), HVO, petroleum diesel. There are three options HVO: steam methane reforming (SMR), biomass gasification (BG), electrolysis solar energy (PVELC). use any...
