WASTE HEAT RECOVERY AND ENERGY CONSERVATION OF ARL DISTILLATION UNIT waste heat recovery and energy conservation of arl distillation unit
Energy conservation and waste heat recovery are important global issues of our times. Attock Oil Refinery Limited (ARL) is pioneer in crude oil refining in Pakistan. After thorough surveys and analysis Heavy Crude Unit (HCU) was selected for energy conservation and waste heat recovery. A detailed study of the plant led to the identification of potential zones for energy conservation and waste heat recovery. Energy conservation was done in the ‘pre-heat train'' which exchanges heat between the products at high temperature and crude at low temperature. By increasing the heat exchange here, both the amount of fuel burnt in the heater to heat crude and the coolant used to cool products could be reduced. Waste heat recovery was done on the flue gases of the combined stack of two heaters which were being exhausted into the atmosphere at a temperature well above its due point temperature. Recovered heat could be used to heat up the intake air for combustion in the heater which was being used at ambient temperature, saving fuel and environment, hence addresing economic and global warming issues.

Optimizing Thermal Energy Recovery, Utilisation and Management waste heat recovery and energy conservation of arl distillation unit
The persistent increase in the price of energy, the clamour to preserve our environment from the harmful effects of the anthropogenic release of greenhouse gases from the combustion of fossil fuels and the need to conserve these rapidly depleting fuels has resulted in the need for the deployment of industry best practices in energy conservation through energy efficiency improvement processes like the waste heat recovery technique. In 2006, it was estimated that approximately 20.66% of energy in the UK is consumed by industry as end-user, with the process industries (chemical industries, metal and steel industries, food and drink industries) consuming about 407 TWh, 2010 value stands at 320.28 TWh. Due to the high number of food and drink industries in the UK, these are estimated to consume about 36% of this energy with a waste heat recovery potential of 2.8 TWh. This work presents the importance of waste heat recovery in the process industries in general, and in the UK food industry in particular, with emphasis on the fryer section of the crisps manufacturing process, which has been identified as one of the energy-intensive food industries with high waste heat recovery potential

Exhaust gas-Thermic Fluid heat Recovery Unit For Diesel Generator Set waste heat recovery and energy conservation of arl distillation unit
Energy conservation is equivalent to energy generation and transmission at 100% efficiency. Combined heat and power (CHP) is an important concept as fuel is used to generate two different forms of energy simultaneously. This book reports a project done at a bottle-cap manufacturing company, where a diesel generating set is employed as backup source of electrical energy. The possibility of using heat from exhaust gases to heat thermic fluid is explored. The design process for the heat recovery heat exchanger and other components is presented. The hot thermic fluid can be used for process heating for making the bottle-caps. It is estimated that around 50 kW heat can be recovered using a shell and tube heat exchanger for the 125 KVA diesel generator set. The payback period is around 480 days. This work thus demonstrates feasibility of such CHP system for process industries. It would also help people in the trade to design such system and also evaluate them.

Feasibility study of Waste Heat Utilization in a Sheet Glass Factory waste heat recovery and energy conservation of arl distillation unit
Waste heat utilization is well known for saving energy, cost and environment, but its practical implementation is not common especially in developing countries. Heat is produced as a result of energy usage. Overall efficiency of the process improves if waste heat is utilized before it is lost to environment. This book discusses the waste heat recovery system designed for a Glass Factory in Pakistan. In order to extract heat from flue gases, the dew point temperature is first calculated in order to have a lower limit of flue gas exit. The exergy of flue gases is then determined based on this limiting value. This available energy is to be used to preheat the furnace oil during the low ambient temperature season. In order to impart this energy to the furnace oil, two heat exchangers have been designed. The first heat exchanger transfers heat from the flue gases to an intermediate heat transfer medium. The second heat exchanger is designed to transfer heat from to the furnace oil. An insulated piping network is also designed in order to meet the purpose. Two pumps are selected in order to pump these fluids. The expected payback period of investment is also calculated.

SAARC Renewable Energy, Efficiency Challenges & Opportunities waste heat recovery and energy conservation of arl distillation unit
SAARC is a diverse conglomerate of nations, mostly developing ones, where the demand for power has soared, propelled by the inexorable inertia of population explosion and aspirations for higher quality of life. Governments around the world are motivated to diversify their energy resources and find an alternative cheaper and a cleaner source of energy. Energy Conservation & Energy Efficiency (EC&EE) is a movement to resolve & to plug in all kind of inefficiencies and wastage in all aspect of Energy Conservation. All sector of economy can conserve energy to the extent of 25% of total energy consumption. It is very important to make a note that Energy Conservation & Energy Efficiency (EC&EE) cannot be very effective where policies and prices are not appropriate. The vital role of Government must be to move toward energy prices that reflect true costs, discourage waste, and make conservation economically profitable for individuals and the society. The book consist of Road Map and action plan for SAARC countries to improve there energy inefficiencies from all sector of economy. SAARC Region security of supply as regards oil and gas in particular has been weakened in the long term.

Design Of Var System Using Waste Heat Recovery Of Diesel Genset waste heat recovery and energy conservation of arl distillation unit
A vapor absorption refrigeration system provides cooling using a heat source rather than electrical input as in the more familiar vapor compression cycle. It seems unreasonable that cooling can be achieved with heat, but that is what occurs within an absorption system.The differences cause an absorption system to use little to no work input, but energy must be supplied in the form of heat. This makes the system very attractive when there is a cheap source of heat, such as solar heat or waste heat from electricity or heat generation. Absorption chillers have recently gained widespread acceptance due to their capability of not only integrating with cogeneration systems but also because they can operate with industrial waste heat streams.

Thermochemical Recovery of Heat waste heat recovery and energy conservation of arl distillation unit
Chemical recuperation of heat has gained significant interest due to higher magnitude of reaction heat compared to that of the latent heat in conventional (physical) recovery. In particular, two concepts have been identified which engage chemical reactions within the process: Chemical Recuperation of Heat through Fuel Synthesis and Chemical Recuperation of Heat through Reaction Coupling. The first concept uses the recovery of surplus heat by chemically manipulating the fuel through an endothermic reaction. The result is the generation of a secondary fuel within the cycle which can be used to reduce the process primary fuel consumption and thus increase the overall efficiency. Based on the second concept, one can temporally store the heat using a pair of endothermic/exothermic reactions for later release to system or continuous upgrade of the heat temperature level. It is of interest if the chemical recuperation of heat can be realized through integration of the two concepts. The inclusion of chemical reactions for recuperation of heat will form the next phase in the heat recovery sector as it offers the possibility of extracting a vast remnant of waste heats.
