Purge gases from hydrocrackers and hydrotreaters and refinery off-gases are important
hydrogen sources. Some of these hydrogen sources are also rich in light hydrocarbons that …

The hydrogen network plays an important role in maintaining the stable production of the
refinery. However, the disconnected hydrogen network and production system has led to a …

Modeling and optimization of large-scale refinery scheduling problems is challenging
because of their complexity and size. Herein, we propose a mathematical model to …

In developing countries like Indonesia, adding a new unit for hydroprocessing facilities is
more efficient than modifying the existing equipment. When the addition occurs, refiners …

A refinery hydrogen network is crucial for the processing of increasingly deteriorating heavy
crude oil into light clean fuels, for which pressure swing adsorption (PSA) is indispensable in …

Process design procedures under uncertainty result in stochastic optimization problems
whose resolution is complex due to the large uncertainty space, which hinders the …

Tighter environmental legislation across the globe pushes refineries to produce more
cleaner fuel. This restriction is more impactful to developing nations, like Indonesia …

Global warming has become increasingly serious over the last decade. As one of the
greenhouse gas (GHG) emission contributors, petroleum refineries are now encountering …

Relevance. The relevance of investigating the processes of amine gas purification is
manifested in the constant need to improve this technology to effectively reduce emissions of …

A stochastic programming modeling framework based on mass transfer mechanism was
proposed, which took the uncertainty of crude oil properties into consideration, to achieve …
