Background: Iran is located in the seventh rank in terms of CO2 emissions resulting from the fuel combustion in the world. Gas compressor booster stations, due to the several sources of contaminants, are causing the release of large amounts of CO2 and CH4, which will cause climate change therefore, estimating the emissions of the gases from oil and gas, different processing units are necessary....

Future exploitation scheme of an oil reservoir in each cycle within its production life depends on the profitability of the current extraction scenario compared with predicted recoveries that acquire with applying other available methods. In fractured reservoirs appropriate time to pass from the gas injection process into chemical enhanced oil recovery (EOR) firmly depends on the oil extraction...

A number of commercial processes are available for removing hydrogen sulfide (H2S) from natural gas, tail gas from the Claus Process (containing un-reactive sulfur compounds, particularly CS2 and COS), coke-oven gas, pyrolysis gas and solution tail gas from heavy oil production. These processes are often limited by economics and technology. In the economic range from about 0.1 to 15 tons sulfur...

This paper presents the fabrication of controlled release devices for anticancer drug paclitaxel using supercritical antisolvent method. The thermodynamic and hydrodynamic effects during supercritical antisolvent process on the particle properties obtained were investigated. Scanning electron microscopy was employed to study particle sizes and morphologies achieved. It was observed that increas...

Membrane gas separation for carbon capture has traditionally been focused on high pressure applications, such as pre-combustion capture and natural gas sweetening. Recently a membrane-cryogenic combined process has been shown to be cost competitive for post-combustion capture from coal fired power stations. Here, the membrane-cryogenic combined process is investigated for application to post-co...
