a b s t r a c t
In this paper, a new method is presented for optimization of heat exchanger networks making use of genetic algorithm and Sequential Quadratic Programming. The optimization problem is solved in the following two levels: 1- Structure of the optimized network is distinguished through genetic algorithm, and 2- The optimized thermal load of exchangers is determined through Sequential Quadratic Programming. Genetic algorithm uses these values for the determination of the fitness. For assuring the authenticity of the newly presented method, two standard heat exchanger networks are solved numerically. For representing the efficiency and applicability of this method for the industrial issues, an actual industrial optimization problem i.e. Aromatic Unit of Bandar Imam Petrochemistry in Iran is verified. The results indicate that the proposed multistage optimization algorithm of heat exchanger networks is better in all cases than those obtained using traditional optimization methods such as Pinch Analysis Method and Mathematical Optimization Method.

Byron Smith ⇑ Process Systems Laboratory, School of Mechanical and Building Sciences, Vellore Institute of Technology University, Vellore 632014, Tamil Nadu, India a r t i c l e i n f o Article history: Received 5 September 2012 Accepted 2 August 2013 Keywords: Onboard fuel processor Hydrogen Fuel cell vehicles Process Simulation a b s t r a c t Fuel cell vehicles have reached the commercialization stage and hybrid vehicles are already on the road. While hydrogen storage and infrastructure remain critical issues in stand alone commercialization of the technology, researchers are developing onboard fuel processors, which can convert a variety of fuels into hydrogen to power these fuel cell vehicles. The feasibility study of a 100 kW on board fuel processor based on gasoline fuel is carried out using process simulation. The steady state model has been developed with the help of Aspen HYSYS to analyze the fuel processor and total system performance. The components of the fuel processor are the fuel reforming unit, CO clean-up unit and auxiliary units. Optimization studies were carried out by analyzing the influence of various operating parameters such as oxygen to carbon ratio, steam to carbon ratio, temperature and pressure on the process equipments. From the steady state model optimization using Aspen HYSYS, an optimized reaction composition in......

Shell and Tube Heat Exchanger

...Effectively Design Shell-and-Tube Heat Exchangers To make the most of exchanger design software, one needs to understand STHE classification, exchanger components, tube layout, baffling, pressure drop, and mean temperature difference. Rajiv Mukherjee, Engineers India Ltd. T hermal design of shell-and-tube heat exchangers (STHEs) is done by sophisticated computer software. However, a good understanding of the underlying principles of exchanger design is needed to use this software effectively. This article explains the basics of exchanger thermal design, covering such topics as: STHE components; classification of STHEs according to construction and according to service; data needed for thermal design; tubeside design; shellside design, including tube layout, baffling, and shellside pressure drop; and mean temperature difference. The basic equations for tubeside and shellside heat transfer and pressure drop are wellknown; here we focus on the application of these correlations for the optimum design of heat exchangers. A followup article on advanced topics in shell-and-tube heat exchanger design, such as allocation of shellside and tubeside fluids, use of multiple shells, overdesign, and fouling, is scheduled to appear in the next issue. • baffles; and • nozzles. Other components include tie-rods and spacers, pass partition plates, impingement plate, longitudinal baffle, sealing strips, supports, and foundation.

Solar Thermal System for Southern Ontario

...included. Signature: Date: August 18, 2014 Acknowledgments The author would like to acknowledge the use of the Queen’s University On-line Library for access to Research Journals. 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 use of solar energy to pre-heat water. This report details the equipment necessary for such a domestic solar hot water system (DSHW). The information has been used in a design matrix to create a viable system for southern Ontario from the many alternatives available.

Nassir School of Engineering, Taylor’s University, Malaysia Abstract Refrigerators normally are systems that are used to preserve perishable goods in a house hold by reducing the temperature of the food compartments. However, refrigerators are also infamous for their high electricity consumptions. This paper presents first a comparison between theoretical and experimental determination of the tons of refrigeration (TR) of a vapor compression refrigeration cycle (VCRC). Then, it was looked into the derivation of empirical models, grounded on experimental results, which would provide refrigerator designers a reliable mean to check on the impact of each examined parameter on the TR during the preliminary stage of refrigerator design. It was noted that both evaporator heater power input (EHPI) and refrigerant flow rate (RFR) positively affected the tons of refrigeration, while the effects of condenser water flow rate (CWFR) was negligible. A total of three models generated. As the accuracy of the data for all models were about 99.7%, the minute difference had to be looked in to. Hence, Model 1, considering both evaporator heater power input (EHPI) and refrigerant flow rate......

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.

Green Buildings

...ACE TECHZION 2K15 Implementation and explanation of the Green Building concepts PRESENTED BY Y.SAI KRISHNA 138P1A0137 Towards the implementation and explanation of the Green Building concept Y.SAI KRISHNA (1256sai@gmail.com) Abstract: The “Green Building” is an interdisciplinary theme, where the green building concept includes a multitude of elements, components and procedures which diverge to several subtopics that intertwined to form the green building concept. Generally, the green building is considered to be an environmental component, as the green building materials are manufactured from local eco-sources, i.e. environmentally friendly materials, which are then used to make an eco-construction subject to an eco-design that provides a healthy habitat built on the cultural and architectural heritage in construction while ensuring conservation of natural resources. This ensures disassembling the building components and materials, after a determined building lifetime, to environmentally friendly materials that can be either re-used or recycled. During their lifecycle, the green buildings minimize the use of resources (energy and water); reduce the harmful impact on the ecology, and provide better indoor environment. Green buildings afford a high level of environmental, economic, and engineering performance. These include energy efficiency and conservation, improved indoor air quality, resource and material efficiency, and......
