Energy Engineering Lab

Introduction
 Energy is often defined as the capacity to do work. Several different forms of energy,
such as kinetic, potential, thermal, electromagnetic, chemical, and nuclear have been defined to
explain all known natural phenomena. Energy is converted from one form to another, but it is
never created or destroyed. This principle is called the conservation of energy.
 Energy engineering is a broad field of engineering dealing with energy efficiency, energy
services, facility management, plant engineering, environmental compliance and alternative
energy technologies.
 Chemical engineers work on process plants, where mass and energyare inputs to get
product as an output. Engineers haveto find ways to get product economically. So, they have to
play with mass and energy so that good qualityproduct is obtained in an economical manner
with minimum and efficient use of energy. So, energy engineering is a very important field for
chemical engineers and the lab of this subject provide the necessary practical knowledge to the
students.

Details of Equipment
Softening Point Apparatus
 This apparatus is used to measure softening point of bituminous coal. Softening point is
the temperature degrees C at which a bitumen attains a particular degree of softness with
reference to test conditions. Softening point will tell us that at what temperature the coal starts to
soften. So, it will help us to know that at what temperature deterioration of roads started.
Swelling Index Apparatus
 This apparatus is used to measure swelling index of coal. Swelling index indicates that
how much the given amount of fuelswells after burning. It tells us an indication of the caking
characteristics of the coal.
Carbon Residue Apparatus
 This apparatus is used to find carbon residueof an oil sample. The carbon residue of a
fuel is the tendency to form carbon deposits under high temperature conditions in an inert
atmosphere. High carbon residue can cause knocking and affect engine performance.
Distillation Apparatus
 This apparatus is used to study the general process of distillation which is an important
mass transfer operation in industry.
Cleveland Open-Cup Flash Point Apparatus
 This apparatus is used to measure the flash point and fire point of an oil sample in an
open environment. The flash point of a flammable liquid is the lowest temperature at which it
can form an ignitable mixture in air.
 The fire point is defined as the temperature at which the vapor continues to burn after
being ignited. These are important temperatures in fuel storing.
Close-Cup Flash Point Apparatus (Pensky Marten’s Apparatus)
 This apparatus is used to measure the flash point of an oil sample in close environment.
This temperature is also important in fuel storing.
Saybolt Viscometer
 This equipment is used to study the variation of viscosity with respect to temperature.
Because viscosity is used for various design calculations in chemical engineering.
Redwood Viscometer
 This equipment is used to study the variation of viscosity with respect to temperature.
Because viscosity is used for various design calculations in chemical engineering.
Engler Viscometer
 This equipment is used to study the variation of viscosity with respect to temperature.
Because viscosity is used for various design calculations in chemical engineering.
Aniline Point Apparatus
 This apparatus is used to measure aniline pint of oil sample. Aniline point is the  temperature at which fuel and aniline become immiscible with each other. Aniline point is used
in the determination of cetane number which tells us about the anti-knocking properties of diesel
fuel.
Cloud & Pour Point Apparatus
 This equipment is used to measure cloud and pour point of oil sample. Cloud Point is the
temperature at which waxy crystals in an oil or fuel form a cloudy appearance. The pour point
can be defined as the minimum temperature of a liquid, particularly a lubricant, after which, on
decreasing the temperature, the liquid ceases toflow. These temperatures are important for
transportation and storage of fuels.
Solar Energy Minilab Apparatus
 Solar energy is energy directly from the Sun. This energy is in the form of heat and light.
This energy drives the climate, weather and supports virtually all life on Earth. This equipment is
used to study solar energy as an environmental friendly source of energy as other fossil fuels are
causing serious environmental problems and the behavior of different solar cells connected in
series and parallel arrangements.
