Fractional Factorial Design Optimization Of Nontraditional Completion Fluid For Perforation With Underbalance, Abdul Aziz Abdul Raman
Fractional Factorial Design Optimization Of Nontraditional Completion Fluid For Perforation With Underbalance, Abdul Aziz Abdul Raman
Abdul Aziz Abdul Raman
Optimal well performance is always associated with the creation of a clean and undamaged connection between wellbore and reservoir. However, it is apparent that the use of shaped-charge perforating tends to produce perforation-induced formation damage. This damage impairs fluid flow and decreases well productivity. To minimize and eliminate this damage, underbalance perforating should be considered. Underbalance perforating has been considered as one of the best means of providing a transient surge flow for tunnel cleanup. This paper introduces the formulation of super lightweight completion to achieve underbalance condition. The formulation was optimized using fractional factorial design. The result indicates that …
Potassium Hydroxide Catalyst Supported On Palm Shell Activated Carbon For Transesterification Of Palm Oil, Abdul Aziz Abdul Raman
Potassium Hydroxide Catalyst Supported On Palm Shell Activated Carbon For Transesterification Of Palm Oil, Abdul Aziz Abdul Raman
Abdul Aziz Abdul Raman
In this study, potassium hydroxide catalyst supported on palm shell activated carbon was developed for transesterification of palm oil. The Central Composite Design (CCD) of the Response Surface Methodology (RSM) was employed to investigate the effects of reaction temperature, catalyst loading and methanol to oil molar ratio on the production of biodiesel using activated carbon supported catalyst. The highest yield was obtained at 64.1 °C reaction temperature, 30.3 wt.% catalyst loading and 24:1 methanol to oil molar ratio. The physical and chemical properties of the produced biodiesel met the standard specifications. This study proves that activated carbon supported potassium hydroxide …
High Quality Biodiesel And Its Diesel Engine Application: A Review, Abdul Aziz Abdul Raman
High Quality Biodiesel And Its Diesel Engine Application: A Review, Abdul Aziz Abdul Raman
Abdul Aziz Abdul Raman
The continuous increasing demand for energy and the diminishing tendency of petroleum resources has led to the search for alternative renewable and sustainable fuel. Biodiesel is best substitute for petro-diesel and also most advantageous over petro-diesel for its environmental friendliness. The quality of biodiesel fuel was found to be significant for its successful use on compression ignition engines and subsequent replacement of non-renewable fossil fuels. Conventional biodiesel separation and purification technologies were noticed to yield lower quality biodiesel fuel with resultant excessive energy and water consumptions. Membrane technology showed more potential for effective and efficient separation and purification of biodiesel. …
Quantitative Risk Assessment For The Transport Of Ammonia By Rail, Abdul Aziz Abdul Raman
Quantitative Risk Assessment For The Transport Of Ammonia By Rail, Abdul Aziz Abdul Raman
Abdul Aziz Abdul Raman
Risk assessments are considered to be an essential tool in ensuring the safety of engineering projects. The benefits of using risks assessments have prompted its acceptance in the safety legislation for a number of industries. The use of quantitative risk assessment for rail transportation of hazardous materials has gained more attention in recent years, because the amount of the transported hazardous materials is large, and the transportation route often passes through populated areas, such as cities. In this study, the risk for the ammonia transportation by rail in Malaysia was conducted by combining the results from a previous failure frequency …
Cohesiveness And Flowability Properties Of Silica Gel Powder, Abdul Aziz Abdul Raman
Cohesiveness And Flowability Properties Of Silica Gel Powder, Abdul Aziz Abdul Raman
Abdul Aziz Abdul Raman
Problem statement: The measurement of powder flowability is a major concern for most industrial processes that deal with the handling of bulk solids as raw materials, intermediates, or products. Approach: The influence of particle size on the flowability of silica gel was investigated using aerated and non-aerated methods. The aerated method involved the measurement of the Hausner Ratio (HR) and Angle Of Repose (AOR) using a Hosokawa Powder Tester (PT-S), while the non-aerated method involved a Cohesion Index (CI) measurement based on a Stable Micro Systems TA.XT Plus texture analyzer. The mean size diameters of the fine and coarse powders …
Application Of Natural Clay To Formulate Nontraditional Completion Fluid That Triples Oil Productivity, Abdul Aziz Abdul Raman
Application Of Natural Clay To Formulate Nontraditional Completion Fluid That Triples Oil Productivity, Abdul Aziz Abdul Raman
Abdul Aziz Abdul Raman
In the last decades, the problem of perforation damage has been considered as the major factor for the reduction of oil productivity. Underbalance perforation is considered as one of the best means to minimize or overcome this problem. By maintaining wellbore pressure lower than formation pressure, perforation damage could be minimize or eliminated. This can be achieved by the use of nontraditional lightweight completion fluid. This paper presents the effect of natural clay in formulating nontraditional completion fluid to ensure successful perforation job and increase of production rate. Natural clay is used as homogenizing agent to create a stable and …
Methanol Recovery During Transesterification Of Palm Oil In A Tio2/Al2o3 Membrane Reactor: Experimental Study And Neural Network Modeling, Abdul Aziz Abdul Raman
Methanol Recovery During Transesterification Of Palm Oil In A Tio2/Al2o3 Membrane Reactor: Experimental Study And Neural Network Modeling, Abdul Aziz Abdul Raman
Abdul Aziz Abdul Raman
High quality palm oil biodiesel can be produced by combination of alkali transesterification and separation processes in a TiO2/Al 2O3 membrane reactor. Due to the small molecular size, methanol molecules are able to pass through the membrane along with the products. Since methanol is one of the process reactants it is necessary to be recovered. Methanol recovery by means of continuous distillation was employed and the influences of different operational parameters including heating temperature permeate flow rate and reactants ratio were investigated. The results indicate that these parameters have significant effects on the rate of methanol recovery. To simulate the …
Phytoremediation Of Soil Contaminated With Used Lubricating Oil Using< I> Jatropha Curcas, Abdul Aziz Abdul Raman
Phytoremediation Of Soil Contaminated With Used Lubricating Oil Using< I> Jatropha Curcas, Abdul Aziz Abdul Raman
Abdul Aziz Abdul Raman
Soil contamination by used lubricating oil from automobiles is a growing concern in many countries, especially in Asian and African continents. Phytoremediation of this polluted soil with non-edible plant like Jatropha curcas offers an environmental friendly and cost-effective method for remediating the polluted soil. In this study, phytoremediation of soil contaminated with 2.5 and 1% (w/w) waste lubricating oil using J. curcas and enhancement with organic wastes [Banana skin (BS), brewery spent grain (BSG) and spent mushroom compost (SMC)] was undertaken for a period of 180 days under room condition. 56.6% and 67.3% loss of waste lubricating oil was recorded …
