Enhanced BTX Production in Refineries with Sulfur Dioxide Oxidation by Thermal Integrated Model

Abstract

More stringent environmental regulations as well as limitations of traditional energy sources lead to the development of innovative techniques to supply the required energy of different industries. Multifunctional autothermal reactors as a novel strategy in process integration technology have been introduced as a response to this requirement. The catalytic naphtha reforming process is one of the main processes in the refinery industries which demand several sources of energy to manage the existing reactions. Also, oxidization of sulfur dioxide to sulfur trioxide as a highly exothermic reaction is one of the typical solutions to reduce and control this greenhouse gas in various industries. According to the main aims of process integration and by considering environmental regulations, a novel thermal integration model is proposed. The results demonstrate the aromatic upgrading and high conversion of sulfur dioxide in this model.

Designing a simple volumetric apparatus for measuring gas adsorption equilibria and kinetics of sorption. Application and validation for CO2, CH4 and N2 adsorption in binder-free beads of 4A zeolite

“…Nowadays, one of the world challenging issues is the global climate change and rising level of greenhouse gases (GHGs) in the atmosphere, originating from anthropogenic activities [1,2]. This environmental concern deriving from the combustion of coal, petroleum and petrochemical industries [3,4] is expected to be intensified as consequence of economic growth and industrial development [5][6][7]. In this context, carbon capture and storage technology has been introduced as a promising policy to reduce the GHGs emissions as well as decrease the mitigation costs of relevant industries [8].…”

Compost from Municipal Solid Wastes as a Source of Biochar for CO2 Capture

“…The coal-and natural gas-fired power plants released 11.1 Gt of CO 2 , nearly 30 % of the total global emissions in 2012 [2,3]. In this way, the combustion of coal, also oil and natural gas industries including naphtha refineries [4,5] and petrochemical complexes [6,7], are the main industrial sources of CO 2 emissions [8,9]. As consequence of these industrial activities, the CO 2 percentage exceeded 50 ppm in the atmosphere from the maximum allowable level in the pre-industrial period until now (280-400 ppm) [10,11].…”

Analyses of Adsorption Behavior of CO2, CH4, and N2 on Different Types of BETA Zeolites

“…On the other hand, while natural gas is one of the favorable energy sources in the world, the applications of this energy source has still some problems because of the presence of several impurities such as nitrogen and CO 2 [5,9]. Beside of its toxic effects, CO 2 corrodes the transportation and storage systems in the presence of water.…”

“…Beside of its toxic effects, CO 2 corrodes the transportation and storage systems in the presence of water. Also, the significant amounts of nitrogen in the natural gas should be purified to meet the pipeline quality for minimum heating value specifications, typically > 90 % methane [9,10]. As a result, the natural gas upgrading should be implemented during the sweeting processes to meet the ''pipeline-quality'' methane.…”
