Carbon dioxide (CO2) injection is one of the most effective methods to improve enhance oil recovery. While the local displacement in CO2 injection process is highly dependent on minimum miscibility pressure (MMP), so this is one of the main factors in design of CO2 injection operations. There are several experimental methods utilized to determine MMP such as slim tube displacement and rising bubble...
Natural gas is an important source of energy. It is efficient, versatile and abundantly available. Calcium chloride (CaCl 2 ) dehydrator is the most common non-regenerative adsorption system in natural gas industry. As the need for natural gas increases, calcium chloride dehydration can help to make some gas wells more profitable to operate gas from remote or offshore wellheads, gas of a low...
Microbial fuel cells (MFCs) are the most recent bioelectrical devices which convert biodegradable organic matters to bioelectricity in presence of active biocatalyst. This system can generate electrons (e − ) and protons (H + ), in which electrons transfer from anode compartment to cathode chamber through an external circuit. MFC architect is one of important factor that effects on...
Viscosity is an important fluid property because of its direct relation with the fuel injection process for engines. The kinematic viscosity of biodiesel at 313K should satisfy the range specified by the international biodiesel standards. In this study, an artificial neural network (ANN) method was developed to predict the biodiesel kinematic viscosity at 313K with the experimental data of 105 biodiesel...
Engine performance and emissions depend on a variety of parameters affecting the engine. Thanks to utilization of modern diesel engine with mechatronic systems, the number engine actuators increase significantly. The actuators can affect the internal states (operational parameters) of diesel engine such as inlet manifold pressure, EGR rate, quantity and timing of pilot and main injection which in...
Raw natural gases are frequently saturated with water during production operations. It is crucial to remove water from natural gas using dehydration process in order to eliminate safety concerns as well as for economic reasons. Triethylene glycol (TEG) dehydration units are the most common type of natural gas dehydration. Making an assessment of a TEG system takes in first ascertaining the minimum...
