In this paper, energy, exergy, and sustainability analyses are performed on the Karun
petrochemical nitric acid plant in Mahshahr at varying ambient temperatures to reveal …

Methanol synthesis is an exothermic reaction where heat is removed by using it for boiling
water. This heat can be utilized for endothermic reactions in thermally coupled reactors. The …

The modern low-energy production processes of urea and ammonium nitrate (AN) are
analysed and compared regarding to the natural resources consumption efficiency and GHG …

Ostwald process for nitric acid production was simulated using Aspen HYSYS. Effects of
input parameters on concentration of nitric acid in the product show increase in mole fraction …

Ethylene oxide (EO) is an important petrochemical used for different applications in chemical
process industries. EO production cost is higher due to price of ethylene and silver catalyst …

Nitric acid production begins with the oxidation process of ammonia in the reactor. The aim
is to cool the NOx gas as much as possible for high efficiency. It was aimed to increase the …
