asphaltene instability is one of the major problems in gas injection projects throughout the world. numerous models have been developed to predict asphaltene precipitation; the scaling equation is an attractive tool because of its simplicity and not involving complex properties of asphaltene. in this work, a new scaling model is presented to account for asphaltene precipitation due to gas inje...
different recovery mechanisms are activated during the production from reservoirs. wells sometimes are kept with the injection. therefore the evaluation of injection indices depended on material injection, seems to be necessary. this study is going to determine the drive indices for a reservoir by making a model using eclipse. the model consists a gas cap and aquifer, in which there is an injec...
an industrial gas turbine has the characteristic of decreasing output power on hot summer days while electricity demand peaks. steam injection in gas turbines has been used for many years to prevent the loss of performance of gas turbines caused by high ambient temperature. vodoley system is a closed steam injection gas turbine cycle (csigtc), which is known as a self-sufficient in steam produc...
Different modified atmosphere conditions with various CO2 concentrations on microbial load (psychrophile, mesophile aerobic and anaerobic bacteria) and physico-chemical properties of barramundi (Lates calcarifer Bloch) fillets stored at 8°C were compared to determine the best packaging conditions. The gas conditions evaluated were 100% CO2 (M1), 75% CO2/25% N2 (M2), 50% CO2/50% N2 (M3), 25% CO...
In a refrigeration cycle, some of the oil circulates and resides in cycle components. The worst scenario of oil circulation in the cycle is where a large amount of oil is retained outside the compressor. High oil retention causes system performance and reliability degradations. The purpose of this study is to experimentally clarify oil retention and pressure drop characteristics due to the pres...
Saline aquifer geological carbon sequestration (SAGCS) is considered most attractive among other options for geological carbon sequestration (GCS) due to its huge sequestration capacity. However, in order to fully exploit its potential, efficient injection strategies need to be investigated for enhancing the storage efficiency and safety along with economic feasibility. In our previous work, we...
The presence of natural gas hydrates at all active and passive continental margins has been proven. Their global occurrence as well as the fact that huge amounts of methane and other lighter hydrocarbons are stored in natural gas hydrates has led to the idea of using hydrate bearing sediments as an energy resource. However, natural gas hydrates remain stable as long as they are in mechanical, t...
The paper discusses the various methods used in Europe to reduce emissions of pollutants from the stack gases of municipal incinerators. With respect to NOx, the paper mentions two experimental postcombustion control approaches involving the addition of chemicals to the wet-scrubber system to oxidize or reduce the NOx to absorbable NO 2 or dischargeable N 2. As pointed out , these methods would...
Flue gas from a plant using fossil fuels contains CO2. Thus power/process plants using fossil fuels contribute to climate change if CO2 in flue gas is not captured. The process of CO2 capture from flue gas is called „postcombustion‟ CO2 capture. Existing plants may be retrofitted with this process to minimize CO2 emission. Amine solutions are mostly used for this process to scrub the flue gas. ...
We report a quantitative study of the effect low-concentration methanol (MeOH) on formation and dissociation hydrates based CH4 CO2/N2 guest molecules. The kinetic promotion ability MeOH is also compared with anionic surfactant sodium dodecyl sulfate (SDS, 100 ppm, 50 ppm). effects concentration changes (1 wt% 5 wt%), pressure (p = 80–120 bar), molecules (CH4 CO2), temperature °C below 0 °C) ar...
