Demand for this black viscous liquid is growing every day in this era if modern technology. Electricity, vehicles and synthetics are among the major consumers of petroleum fluids or crude oil. Crude oil could be referred to as the ‘black gold’ due to its expensive price and complicated production process. Unlike gold, crude oil naturally is useless in its primary form. A process called fractional distillation or petroleum refining need to be carried out onto the crude oil to separate...

...that best friend a man can ever get is a book but we at this juncture realize that only books cannot give all the information a person seeks. When any student is unable to understand a particular topic, he is advised to imagine the whole matter and then try to understand it. Normally, this method succeeds. But in engineering stream considering the study of wide range of process and equipments involved in it, it is hard to understand the unit operations and processes just through books or even with imagination .Unless one happens to see the process, equipments, he is like a soldier who knows to fire the gun ,but is yet to face a war. Industrial training is one of the most vital part of a syllabus of chemical engineering, which not only teaches one the industrial unit operations, equipments and other technical aspects, but also teaches discipline, interaction with various people irrespective of their posts, the importance of teamwork, etc. This report contains a brief introduction to GUJRAT REFINERY and knowledge gathered about various units in refinery during the training. ACKNOWLEDGEMENT I would like to express my gratitude to all those who gave me the possibility to complete this training. I want to thank the department of training and management of Gujarat refinery for giving me permission to commence this training. I have furthermore to thank the officers of production who giving me such knowledge of about the plant and production process. It’s really great opportunity...

...on the topic ‘Distillation Process’. I would also show my gratitude towards my Programme Leader Dr. Monika Thakur and our HOD Dr Amarinder Singh Bawa for including such a project in my course curriculum which gave me a chance to gain knowledge as much as I can in this field. Thank you Varun Gadodia BTech Food Technology IV semester Amity Institute of Food Technology Introduction This report examines the distillation process. This will enable the reader to understand the necessary components along with distillation calculations. Distillation is a process that separates two or more components into an overhead distillate and bottoms. The bottoms product is almost exclusively liquid, while the distillate may be liquid or a vapour or both. The separation process requires three things. First, a second phase must be formed so that both liquid and vapour phases are present and can contact each other on each stage within a separation column. Secondly, the components have different volatilities so that they will partition between the two phases to different extent. Lastly, the two phases can be separated by gravity or other mechanical means. Distillation differs from absorption and stripping in that the second phase is created by thermal means. The report also high lights the important equipments/methods used for distillation as well as its...

...ABSTRACT Nylons comes in many types but the most common and widely used in textile and plastic industries are Nylon 6 and Nylon 6,6. Nylon 6,6 is made up of two monomers each containing 6 carbon atoms. One of them is Adipic Acid which is a dicarboxylic acid. It is manufactured by oxidation of Cyclohexanol which is produced by oxidative cleavage of cyclohexane or by hydrogenation of phenol. Commercially Cyclohexane is preferred as raw material because of its lower cost and a two-step mechanism involving Nitric acid is used to produce Adipic Acid. This process has higher selectivity and yield than other processes. The only concern with this process is the emission of nitrogen oxides in the gas effluents which is a major environmental concern. 1. Introduction Adipic acid is an organic compound, with formula HOOC (CH2)4COOH, which is a white crystalline solid and one of the most important Dicarboxylic acid. It is Odorless, Colorless and freely soluble in Ethanol, Methanol and Acetone. Other Important properties of Adipic acid is shown in Table 1.From Industrial perspective it is used mainly in Nylon-6, 6 production. About 2.5 billion kilograms of this white crystalline powder are produced annually. In US it is mainly produced by three companies at four manufacturing plants, with nearly two-thirds of the total production, 860,000 tons capacity occurring at DuPont's two Texas facilities. The use of adipic acid in food items have started in recent times and this has created a demand...

...engine because the turbine forces more intake air, proportionately more fuel, into the combustion chamber than if atmospheric pressure alone is used. Turbochargers were originally known as a turbosuperchargers when all forced induction devices were classified as superchargers, nowadays the term "supercharger" is usually applied to only mechanically-driven forced induction devices.[3] The key difference between a turbocharger and a conventional supercharger is that the latter is mechanically driven from the engine often from a belt connected to the crankshaft, whereas a turbocharger is driven by the engine's exhaust gas turbine. Compared to a mechanically-driven supercharger, turbochargers tend to be more efficient but less responsive. Twincharger refers to an engine which has both a supercharger and a turbocharger. Turbos are commonly used on truck, car, train and construction equipment engines. Turbos are popularly used with Otto cycle and Diesel cycle internal combustion engines. They have also been found useful in automotive fuel cells Operating principle In most piston engines, intake gases are "pulled" into the engine by the downward stroke of the piston[16][17] (which creates a low-pressure area), similar to drawing liquid using a syringe. The amount of air which is actually inhaled, compared with the theoretical amount if the engine could maintain atmospheric pressure, is called volumetric efficiency.[18] The objective of a turbocharger is to improve an engine's volumetric...

Abstract Global warming is one of the most potentially disastrous issues facing mankind in the early 21st century, considered to be caused by man-made greenhouse gas emissions. Approximately 30% of the man-made carbon dioxide (CO2) emissions causing global warming is created by the burning of fossil fuels to produce electricity or used as a direct energy source. The use of solar energy to pre-heat water for industrial, commercial and institutional and residential purposes can reduce electricity usage by up to 2% to 6% in southern Ontario. Adding the emissions from using natural gas directly to heat water a figure of 5% to 17% reduction in CO2 emissions can be derived by the...

...INTRODUCTION Background of the Study The evolution of industrialization and mechanization in the 21st century made it possible to transform manual equipment into modern machinery. With this development, global reliance on petroleum-based fuel is constantly increasing, giving rise to a challenge on energy sufficiency. Negative impacts, such as greenhouse gas (GHG) emissions, are associated with the combustion of these petroleum-based fuels (MacLellan, 2010). Major GHG contributors identified by the United States Environmental Protection Agency (EPA) include industry (20%), residential and commercial (11%), and agriculture (8%) (Bogart, 2013). Adverse effects on health and the environment of using petroleum-based fuels, thus, urge scientific community to search and develop alternative renewable fuel to replace the current and existing petroleum-based fuels. Biofuels have been demonstrated by several researches to reduce GHG emissions as compared to gasoline (petrol) (Leen, 2012). Among the alternative biofuels, bioethanol has received considerable attention in transportation sector because of its utility as an octane booster, fuel additive, and even as neat fuel (Mudliar, et. al., 2009). Bioethanol can be derived from organic materials, such as energy crops like corn, wheat, sugar cane, sugar beet, and cassava, among others (Neves, et. al., 2007). However, due to their primary utility as food, these crops cannot provide the global demand for bioethanol production. Among...

...------------------------------------------------- Temperature controlled applications In a temperature control application, the inlet temperature of the secondary fluid to the heat exchanger may change with time. This means that in order to maintain a consistent secondary fluid outlet temperature, the heat supplied to the heat exchanger must also vary. This can be achieved by using a control valve on the inlet to the primary side of the heat exchanger, as shown in Figure 13.2.1. Fig. 13.2.1 Typical temperature control of a steam/water shell and tube heat exchanger A control valve is used to vary the flowrate and pressure of the steam so that the heat input to the heat exchanger can be controlled. Modulating the position of the control valve then controls the outlet temperature of the secondary fluid. A sensor on the secondary fluid outlet monitors its temperature, and provides a signal for the controller. The controller compares the actual temperature with the set temperature and, as a result, signals the actuator to adjust the position of the control valve. For a constant heating area and heat transfer coefficient, the rate at which heat is transferred from the steam to the secondary fluid for a particular heat exchanger is determined by the mean temperature difference between the two fluids. A larger difference in mean temperatures will create a large heat transfer rate and vice versa. On partially closing the control valve, the steam pressure and the temperature difference...

...CHM 1101 Introductory Chemistry Dawn Fox Medeba Uzzi August, 2007 Compiled and edited by Medeba Uzzi Authors’ Note This document is an initiative by the authors in an attempt to deal with what they think may be one of the reasons contributing to the relatively high failure rate in the introductory Chemistry course (CHM 1101) at the University of Guyana. It was brought to our attention that many first year students taking CHM 1101 are unable to efficiently cope with the frenetic pace of the Semester system and even less able to deal comprehensively with the large content in CHM 1101. It is hoped that by providing this paper, students will not need to make lots of notes in lectures and so they can focus on grasping the concepts taught. The document is meant to be a guide to the topics covered in CHM 1101 and is by no means exhaustive. Students are still required to attend classes regularly and punctually and to engage meaningfully in lectures and tutorials. Further, supplemental reading of these topics in any good General Chemistry text is expected. Dawn Fox Medeba Uzzi 2 SECTION 1 – Modules A – D: section deals with the foundation for chemistry. It introduces students to matter & its classification, Atom & its structure, Periodic table and chemical rxns. Introduction to Science and Measurement What is Chemistry? – Chemistry is the study of matter and its transformations Natural sciences refer to the systematic study of the natural world (our...
