Course Description
Process engineering includes the generation, study and analysis of process designs. All processes must obey some fundamental laws of conservation. We can group these into conservation of matter and conservation of energy. Given a set of operations, if we draw a box around this set, the amount of mass going in must equal the amount going out; the same applies to the energy. Mass and energy balance operations are fundamental operations in the analysis of any process. This training course describes the basic principles of mass and energy balances. Material quantities, as they pass through processing operations, can be described by material balances. Such balances are statements on the conservation of mass. Just as mass is conserved, so is heat. The energy coming into a unit operation can be balanced with the energy coming out and the energy stored. Energy balances are often complicated because forms of energy can be inter converted, for example mechanical energy to heat energy, but overall the quantities must balance.
Material and heat balances are very important in an industry. These are fundamental to the control of processing, particularly in the control of yields of the products. The first M & E balances are determined in the exploratory stages of a new process, improved during pilot plant experiments when the process is being planned and tested, checked out when the plant is commissioned and then refined and maintained as a control instrument as production continues. When any changes occur in the process, the M & E balances are revisited again.
Material and heat balances can be simple, at times they can be very complicated, but the basic approach is general. Experience in working with the simpler systems such as individual unit operations will develop the facility to extend the methods to the more complicated situations, which do arise. The use of computer programs is helpful in readily analyzing very complex mass and energy balances and therefore it is a very effective tool in everyday process management to maximize product yields and minimize costs.
Engineers do mass and heat balance to account for what happens to each of the inputs that enters the operations and analyze the outputs for alternative processes, energy conservation and environment monitoring pollution dispersion models. Inefficient use of raw materials and energy in production processes are reflected as wastes.
This course will introduce you to the fundamental principles and of mass and heat balance as applicable to the process industry. It introduces the principles of mass and energy conservation and emphasizes on the development of systematic approaches in calculations used for design and analysis of production and physical processes. These processes are involved in a wide range of applications from environmental protection, energy conservation to value-adding manufacturing processing. Participants will learn writing mass and energy balance equations, selecting design variables, and preparing algorithms by way of examples.
