Performance assessment and process optimization of a sulfur recovery unit: a real starting up plant.

Sulfur recovery units (SRU) have an important role in the industrial production of elemental sulfur from hydrogen sulfide, whereas the generated acidic gas emissions must be controlled and treated based on local and international environmental regulations. Herein, Aspen HYSYS V.11 with Sulsim software is used to simulate the industrial and treatment processes in a refinery plant in the Middle East.

Exergy study of amine regeneration unit using diethanolamine in a refinery plant: A real start-up plant.

Refinery plants use diethanolamine (DEA) solutions for gas sweetening. The role of DEA is to absorb HS from sour gas. Amine Regeneration Units (ARU) are used to regenerate the rich Amine with HS from refinery units to Lean Amine.

A hierarchical approach for the design improvements of an Organocat biorefinery.

Lignocellulosic biomass has emerged as a potentially attractive renewable energy source. Processing technologies of such biomass, particularly its primary separation, still lack economic justification due to intense energy requirements. Establishing an economically viable and energy efficient biorefinery scheme is a significant challenge.

Reducing CO2 emissions and energy consumption of heat-integrated distillation systems.

Distillation systems are energy and power intensive processes and contribute significantly to the greenhouse gases emissions (e.g. carbon dioxide).
