In this study the enthalpies of dissociation for pure methane and pure carbon dioxide was calculated using a hydrate equilibrium data obtained in this study. The enthalpy of dissociation was determined using Clausius-Clapeyron equation. The results were compared with the values reported in literature obtained using various techniques. Keywords—Enthalpies of dissociation, methane, carbon dioxide...

In recent years, green solvents named deep eutectic solvents (DESs) have been found to possess significant properties and to be applicable in several technologies. Choline chloride (ChCl) mixed with urea at a ratio of 1:2 and 80 °C was the first discovered DES. In this article, chemical structure and combination mechanism of ChCl: urea based DES were investigated. Moreover, the implementation o...

In this study, a reformer model simulation to use refinery (Farashband refinery, Iran) waste natural gas. In the petroleum and allied sectors where natural gas is being encountered (in form of associated gas) without prior preparation for its positive use, its combustion (which takes place in flares, an equipment through which they are being disposed) has become a great problem because of its a...

the request for natural gas attention to its adaption with environment and less pollution than the other fossil fuels has the highest growth in last decades. in result this energy has high geopolitical importance. iran with has about 2.18 percent of total world reserves, the largest in the world. but couldn't played important role in the natural gas geopolitics and even it hasn't in b...

An integrated Artificial Neural NetworkParticle Swarm Optimization (PSO) is presented for analyzing global electricity consumption. To aim this purpose, following steps are done: STEP 1: in the first step, PSO is applied in order to determine world’s oil, natural gas, coal and primary energy demand equations based on socio-economic indicators. World’s population, Gross domestic product (GDP), o...

use of zinc and iron oxide are common in the desulfurization process from natural gas. in thisresearch, after determinations of the size and specifications through tem and xrd for each of the metaloxides, two different size ratios were used, 0.66 for zinc oxide and 0.142 for iron oxide. further, absorption of sulfur compounds in gas (hydrogen sulfide (h2s), carbonyl sulfide (cos), methyl mercap...

compressibility factor and viscosity of natural gasses are of great importance in petroleum and chemical engineering. to calculate the natural gas properties in the pipelines, storage systems and reservoirs, the exact values of gas compressibility factor and viscosity are required. a new method that allows accurate determination of compressibility factor and gas viscosity for all types of: swee...
