Abstract:

Foaming and solvent degradation is a major issue in natural gas sweetening unit. Currently, GASCO Company (Abu Dhabi) is using aqueous methyldiethanolamine (MDEA) to scrub H2S/CO2.  Adsorption is mostly applied technology to regenerate MDEA. Polymeric/clay hybrid composite were used in continuous adsorption to remove contaminants using different column diameter and height. This study focusses on the removal of organic acid anions as major contaminant present in lean MDEA. Dimensional analysis has been carried out in order to identify the relevant dimensionless groups involved to provide scale up studies. The adsorption column bed diameter and bed height was changed from 1.5-2.6 cm and 10-45 cm, respectively. The columns with 2.6 cm diameter having 10, 23 and 45 cm height was filled with different weight of adsorbents. It was observed that with increasing bed diameter the breakthrough as well as bed saturation time was increased. The breakthrough curve for lower diameter column was observed to have a sharp slope and shortened mass transfer zone. The bed height of 10 cm had faster breakthrough as compared to 23 and 45 cm bed height. Thus, higher the bed height, higher is the breakthrough as more amount of lean MDEA can be treated.

Abstract:

Ghana was the first sub-Sahara country to gain independence (1957). In the early 1990s, after a long period of military rule, Ghana became a democratic state. Since then, it has been regarded as one of the most stable African democracies. The level of corruption is quite low, there are no violent conflicts and the macroeconomic structure is relatively strong. GDP is around US$38,24 billion, while the total state revenues, including grants, are approximately 30% of GDP. The main export products are gold and cocoa [CIA World Factbook, 2011]. In 2004 the country sold licences for offshore oil exploration and production (so called blocks) to different international companies. In July 2007, Tullow Oil and Kosmos Energy discovered oil in commercial quantities in the western region of Ghana. They named the area “Jubilee Field”. Development of the production site started right away and in December 2010 oil production was officially launched. Since 2007 further discoveries have been made. The Tweneboa field seems to be a second major discovery. In 2007 the former President Kuffour (2000-2008) announced enthusiastically, “With oil as a shot in the arm, we’re going to fly” [BBC News, 2007].

Leema Almakhadmeh

Jordan University of Science and Technology, Jordan

Title: Oil shale combustion under oxyfuel conditions

Time : 10:00-10:20

Speaker
Biography:

 

Leema Almakhadmeh, Associate Professor, Department of Environmental Engineering/Al-Hussein Bin Talal University and Department of Chemical Engineering/Jordan University of Science and Technology- Jordan. B.Sc. and M.S degrees from Jordan University of Science and Technology, Ph.D degree from Stuttgart University/Germany. Research areas are: oxyfuel combustion, pyrolysis and char combustion, emission control technologies (NOx, SOx, PM), and others.

Abstract:

Direct combustion of Jordanian oil shale under oxyfuel conditions was investigated. Unstaged and staged air-firing as well as combustion at 27% O2/73% CO2 (OF27) was conducted successfully. A 20 kW vertical reactor was used at a combustion temperature of 1200◦C. Oil shale- N conversion rate to NO is higher during unstaged air-firing than oxyfuel combustion; they are 27% and 15% for air-firing and OF27 combustion, respectively. NOx emission reduced efficiently by adopting staged combustion technology under oxy-fuel conditions as well as air-firing. In addition, the reduction of simulated recycled NO has been investigated. The actual situation has been simulated by injecting NO in the reactor through the burner during OF27 combustion. The reduction of the injected NO is more efficient with staging compared to unstaged combustion mode; 100% reduction of the injected NO during staged OF27 combustion is registered while for unstaged OF27 combustion it ranges from 57% to 65%. The high sulphur content in Jordanian oil shale is considered one of the biggest challenges for its utilization. The oil shale- S conversion rates to SO2 is lower during unstaged OF27 combustion compared to air-firing; they are 69% and 49% for air-firing and OF27 combustion, respectively. For both unstaged combustion modes, direct limestone injection at different molar Ca/S ratios has been investigated; SO2 emissions are reduced significantly by direct limestone injection. At Ca/S molar ratio of 3, the desulphurization efficiencies are 100% and 95% for OF27 combustion and air-firing, respectively.

Title: Reservoir characterization of typical tight gas in China
Speaker
Biography:

Guo Jianlin, born in Hunan province , China, received his B.S. degree in Petroleum Geology from the China University of Geoscience and his M.S. and Ph.D. degrees from Research Institute of Petroleum Exploration & Development (RIPED), Beijing, China. From 1998, he has worked in the areas of oil & gas geology, reservoir modeling and engineering. He is currently senior engineer of Department of Ordos E&P,RIPED,working mainly on gas development.

Abstract:

After more than ten years of tight gas development practice and technical research, China has successfully solved the technical problems of tight gas development, and it has become the most important contributor to China's natural gas production. Due to the strong heterogeneity of the tight gas reservoir, reserves producing degree and recovery rate is low, it needs more fine geological guidance to solve these problems, so the reservoir characterization of tight gas is crucial. This paper takes the Sulige gas field (the largest gas field in china) as a case study, because of its low abundance and strong heterogeneity, it is challenging for large scale commercial development of this field. Therefore, it is necessary to study the basic characteristics of effective reservoir, and first of all, looking for sweet spots is currently the priority.

Behzad Rostami (Corresponding Author) is an associate Professor of petroleum engineering in the Institute of Petroleum Engineering (IPE) at University of Tehran. His research interests involve gas injection based methods of enhanced oil recovery, foam injection and carbonated water injection, CO2 sequestration in Saline aquifers and depleted hydrocarbon reservoirs, gravity drainage and multi block interaction in fractured media. Rostami has authored more than 40 technical papers in international journals and also supervised more than 30 graduate students. 

Abstract:

Performance of CO2 and hydrocarbon (HC) gas injection into a heavy crude oil was investigated at high pressure/temperature condition, using high permeable well-sorted original reservoir sandstone. Complete series of PVT and slime tube tests were followed by vertical and horizontal gas floods to study the impact of injection rate, injectant type and reservoir pressure. Dimensional analysis was performed to study the involved mechanism and forces. Sometimes direct injection of CO2 may not be practically and economically possible. In addition, in plans for CO2 storage, CO2 as a free phase in a reservoir is coupled with a significant leakage risk that prevents the scenario of direct injection. Therefore, in the second part, the enhancement of heavy oil recovery was tested by the carbonated water injection.

Xu Zhengyu is an senior geologist who gets his expertise in shale gas exploration and tectonics. He mainly engages in selected play and evaluation, tectonic and stru-cture of research work of hydrocarbon in marine and continental basin of South China. Recently, he has summed up the basic characteristics of tectonic, sedimentar-y face and source rock, reservoir and preservation condition of Zhaotong demonstration region in Sichuan basin. He has optimized four favorable play and one sweet and described a gas-field in the demonstration region. He has summed up a series of evaluated technology and optimized way of South China marine shale gas.

Abstract:

            The upper Yangtze region has experienced multi geological events, and there is characteristic of high evolution and strong transformation of the marine shale. So that the shale gas accumulation is very complex. By the comparison of North American and the upper Yangtze shale, Longmaxi formation organic rich shale of the Upper Yangtze Region is older, higher degree of evolution, but the sedimentary environment and lithology basically is the same as North American Barnett shale. Due to Longmaxi shale experienced multi deformation and different burial environment, its hydrocarbon has entered the over-mature stage. North American tectonic is relatively stable and its shale is still in the middle- high mature stage. The upper Yangtze shale gas accumulation and preservation are controlled by the reservoir pore pressure and the sealing of the accumulation unit. Combined the Longmaxi shale reservoir and the stratigraphy deformation characteristics of the upper Yangtze region, the shale gas sweet is controlled by deep shelf anoxic face and structure transformation and adjustment zone. Recently, all of the found Longmaxi shale gas reservoirs locate in gentle wings and axis of residual syncline of the zone. And a series of identification technologies of the shale gas reservoir and prediction technologies of sweet distribution have been summed in the upper Yangtze region. Longmaxi shale gas layer takes it as a feature : high gamma, high acoustic time difference, low P-wave and S -wave velocity ratio, and with high resistance, low density, low compensation neutron anomaly. The Longmaxi sweet layer appears" low frequency wave impedance reflection and AVO anomalies".  The structure transformation and adjustment zone shows the multi-source convergence and natural net-fracture reservoir conditions, therefore good accumulation units of syncline belts become shale gas high production in the upper Yangtze region marine. Therefore Longmaxi shale gas sweet is controlled by deep shelf anoxic face and tectonic transformation and adjustment zone in the upper Yangtze region.

Title: Adsorption dynamics and rate assessment of volatile organic compounds in active carbon

Time : 10:50-11:10

Speaker
Biography:

Jing Zhu was born in 1991. She received the B.Sc. degree from China University of Petroleum, China, in 2011. She is currently working toward the Ph.D. degree in material science and engineering at China University of Petroleum, Beijing, China. Her research interests focus on the application of THz waves.

Abstract:

Volatile organic compounds (VOCs) emanated from car spills and oil and gas development can have mutagenic and carcinogenic effects on human beings. Adsorption using activated carbon with high specific surface area and large pore volume was one of the most widely used and mature methods to recycle VOCs. In this paper, an investigation was presented about terahertz time-domain spectroscopy (THz-TDS) as a novel tool for the characterization of the dynamic adsorption rate of volatile organic compounds, including isooctane, ethanol, and butyl acetate, in the pores of active carbon. The THz-TDS peak intensity (EP) was extracted and corresponded to the measurement time frames. By analyzing EP with time, the entire process could be divided into three physical parts including volatilization, adsorption and stabilization so that the adsorption dynamics could be clearly identified. In addition, based on the pseudo-second-order kinetic model and the relationship between EP and time in the adsorption process, a mathematical model was built in terms of the adsorbed rate parameter and the THz parameter. Consequently, the adsorption rate of isooctane, ethanol, and butyl acetate could be assessed by the THz measurement, indicating that THz spectroscopy could be used as a promising selection tool to monitor the adsorption dynamics and evaluate adsorption efficiency in the recovery of pollutants.

Abstract:

Three types of adsorbents: Bentonite clay Silica gels, Charcoal were selected to evaluate their behavior in minimizing sulfur contents in diesel fuel, and to characterize the more efficient adsorbent. Native diesel fuel with sulfur contents of 0.8% was received in a temperature range between (250-320oC) from fractional distillation of crude oil obtained from field of Kirkuk / Iraq with sulfur contents of 2% was used in this work. Desulfurization was performed in a continuous circulation of 150 ml. of diesel fuel through a glass column (2 cm. id x 25 cm length) containing 100 gm. adsorbent by circulating pump. Adsorption for sulphur contents was investigated at different duration of times i.e. 2hr, 4hrs and 6 hrs. Bentonite exhibited the maximum desulphurization yield of 65 % at 6 hrs adsorption. Surface areas of all adsorbents were characterized by SEM and EDX analysis. The FT-IR study of the desulphurized diesel sample revealed that mostly high molecular weight thioles and thiophenic compounds were depleted during adsorption process.

Title: Characterization of oil-water two phase flow based on terahertz time-domain spectroscopy

Time : 12:25-12:45

Biography:

Yan Song has her expertise in the evaluation and characterization of fluid (microfluidic) flow in the oil and gas field based on new optical method. Her research of oil-water two phase flow based on terahertz time-domain spectroscopy makes supplement of flow pattern analysis in the oil and gas field. 

Abstract:

Understanding the dynamics behaviors of oil-water two phase flow is crucial to important problems in the oil wells and pipelines. Because of the extremely high sensitivity of terahertz wave to hydrogen bonding, a new method to study oil-water two phase flows is put forward to study oil-water two phase flows using the terahertz time-domain spectroscopy (THz-TDS). By comparing the amplitudes of the maximum peak in THz-TDS, the ability of THz-TDS has been shown previously to discriminate the flow pattern for oil-water two phase flow with low water content in rectangular pipe. For further study on oil-water two phase flow, we conduct another experiment using diesel and tap water. the amplitude of THz-TDS of oil-water two phase flow is corresponding to the flow pattern, the flow pattern and the critical flow rate can be distinguished by THz-TDS. When the oil-water mixture flow rates are high, the water phase is intensively impacted by the oil phase, and W/O flow is found and the water content in the test part almost keeps unchanged in this situation, resulting the unchanged THz signal in the measurement. As the decrease of mixture flow rate, the droplets are mainly affected by gravity and the forces associated with the motion reduces. For further decrease in the mixture flow velocities, the number of droplets reduces and the maximum drop size increases, the flow is gravity dominated and then the O & DW/O flow pattern is formed. In order to investigate the effect of the input mixture flow rate on the slip, simulations have been performed under selected mixture flow rates for the two-phase flows with different input water fractions here. The results reveal that the slip is mainly dominated by the mixing flow rate at low flow rates, whereas the effect decreases gradually with increasing flow rate.
