In this research the experimental and theoretical studies on different Enhanced Oil Recovery (EOR) techniques, i.e. Water Flooding (WF), Gas Injection (GI) and Water Alternating Gas process (WAG) were performed on specimens taken from an Iranian carbonate offshore reservoir at the reservoir condition. The experimental results for each specified techniques were compared with the correspondin...

In this research, Zn, Ni, and Cu recovery from mobile phone printed circuit boards was investigated. The initial pH pulp density using Aspergillus niger or Penicillium simplicissimum fungi were optimized to improve the of a central composite design. Fungi able recover 97% Cu. Often for Ni recovery, A. more effective, but in low densities pH, P. preferred. For is appropriate at lower than 6, out...

Extraction of intracellular lipids the oleaginous yeast Yarrowia lipolytica has been systematically studied aiming towards a sustainable extraction process for lipid recovery. Selection suitable industrial (bulk) solvents and parameters that lead to maximization recovery are significant issues be addressed, with applications motivating this study. Biomass from fermentation (MUCL 28849) was used...

A regenerative organic Rankine cycle (RORC) is modeled and optimized for the use of waste heat recovery from a prime mover (PM). Three PMs including, a diesel engine, a gas engine, and a microturbine are selected in this study. Four refrigerants including isobutane, R123, R134a, and R245fa are selected. The nominal capacity of the PM, PM operating partial load, turbine inlet pressure, condenser...

The by-product from tuna processing is a potential source of edible protein. Therefore, it is very important to extract protein from such raw materials for human food. In this study the optimum pH for protein extraction from tuna by-products was optimized by using isoelectric solubilization and precipitation processes. The Response Surface Methodology (RSM) and the single factor model were used...

A sulfate solution containing 1773.965 mg/L Mn2+, 3216.178 Mg2+ and 566.254 Ca2+ was used to perform the maximum recovery of manganese minimum magnesium. Carbonate precipitation due better selectivity for over magnesium other impurities compared hydroxide precipitation. Four factors were studied: pH value, contact time, reaction temperature sodium carbonate consumption. Analysis variance (ANOVA...
