Hydrogen Distribution in Refinery with Nonlinear Programming

Removal of H2S and Mercaptan from Outlet Gases of Kermanshah Refinery Using Modified Adsorbents (Bentonite and Sludge)

In this work, adsorbents, namely bentonite and sludge, modified by iron and copper were used to remove the H2S and mercaptan from Kermanshah refinery. The used adsorbents are inexpensive materials, which substantially decrease the operational costs. The structure of the adsorbents was analyzed using scanning electron microscope (SEM) and energy-dispersive X-ray spectroscopy (EDX). Th...

Optimal Management of a Hydrogen Network in a Petrol Refinery

This paper discusses different aspects of the optimization of the distribution of hydrogen in a petrol refinery through a network that connects production and consumption plants. Due to the lack of reliable information from the field measurements, a previous stage of data reconciliation is required. The hydrogen distribution problem can be formulated as a non-convex NLP one, which implies the p...

Biofertilizer production from gas refinery wastewater

Abstract In this study the wastewater treatment of a gas refinery was investigated by using an aerobic trickle bed filter bioreactor. Using a methanothrophic bacterium was the only difference of this experiment from the common aerobic wastewater treatment processes. In addition to reach the standards of wastewater treatments the other goal of using this special bacterium was the productio...

Green trees for greenhouse gases: a fair trade-off?

While forests retain carbon in plants, detritus, and soils, utility companies spew it into the air as carbon dioxide, the main greenhouse gas behind global warming. Industrial carbon dioxide emissions aren't currently regulated by federal law, but a number of companies are trying to address the problem voluntarily by launching carbon sequestration programs in heavily forested countries, where c...
