  1. PID CONTROL

    A proportional–integral–derivative controller (PID controller or three term controller) is a control loop  feedback mechanism widely used in industrial control systems and a variety of other applications requiring continuously modulated control. A PID controller continuously calculates an error value e(t){\displaystyle e(t)} as the difference between a desired setpoint (SP) and a measured process variable (PV) and applies a correction based on proportional, integral, and derivative terms (denoted P, I, and D respectively) which give the controller its name.

  2. Chemical Kinetics

    Chemical kinetics is the study and discussion of chemical reactions with respect to reaction rates, effect of various variables, re-arrangement of atoms, formation of intermediates etc. There are many topics to be discussed, and each of these topics is a tool for the study of chemical reactions.

  3. Distillation

    Distillation is a widely used method for separating mixtures based on differences in the conditions required to change the phase of components of the mixture. To separate a mixture of liquids, the liquid can be heated to force components, which have different boiling points, into the gas phase. The gas is then condensed back into liquid form and collected.
        Repeating the process on the collected liquid to improve the purity of the product is called double distillation. Although the term is most commonly applied to liquids, the reverse process can be used to separate gases by liquefying components using changes in temperature and/or pressure.
    A plant that performs distillation is called a distillery. The apparatus used to perform distillation is called a still.

  4. ADSORPTION OF REMAZOL BRILLIANT BLUE ON AN ORANGE PEEL ADSORBENT

    A novel orange peel adsorbent developed from an agricultural waste material was characterised
    and utilised for the removal of Remazol Brilliant Blue from an artificial textile-dye effluent. The adsorption
    thermodynamics of this dye-adsorbent pair was studied in a series of equilibrium experiments. The time to
    reach equilibrium was 15 h for the concentration range of 30 mg L-1 to 250 mg L-1. The adsorption capacity
    decreased with increasing temperature, from 9.7 mg L-1 at 20 °C to 5.0 mg L-1 at 60 °C. Both the Langmuir
    and Freundlich isotherm models fitted the adsorption data quite reasonably. The thermodynamic analysis of
    dye adsorption onto the orange peel adsorbent indicated its endothermic and spontaneous nature. Thus, the
    application of orange peel adsorbent for the removal of dye from a synthetic textile effluent was successfully
    demonstrated.

  6. BOILER

    A boiler is an enclosed vessel that provides a means for combustion and transfers heat to water until it becomes hot water or steam. The hot water or steam under pressure is then usable for transferring the heat to a process. 

    Water is a useful and cheap medium for transferring heat to a process. When water is boiled into steam its volume increases about 1,600 times, producing a force that is almost as explosive as gunpowder. This causes the boiler to be extremely dangerous equipment and should be treated carefully.

    Liquid when heated up to the gaseous state this process is called evaporation.  

    The heating surface is any part of the boiler; hot gasses of combustion are on one side and water on the other. Any part of the boiler metal that actually contributes to making steam is heating surface. The amount of heating surface of a boiler is expressed in square meters. The larger the heating surface a boiler has, the more efficient it becomes.

  7. Fuel And Combustion

    The various types of fuels like liquid, solid and gaseous fuels are available for firing in boilers, furnaces and other combustion equipments. The selection of right type of fuel depends on various factors such as availability, storage, handling, pollution and landed cost of fuel. The knowledge of the fuel properties helps in selecting the right fuel for the right purpose and efficient use of the fuel. The following characteristics, determined by laboratory tests, are generally used for assessing the nature and quality of fuels.

  8. liquid liquid extraction

    Liquid–liquid extraction is also known as solvent extraction and partitioning is a method to separate compounds based on their relative solubilities in two different immiscible liquids, usually water and an organic solvent. It is an extraction of a substance from one liquid into another liquid phase.

  10. storage of flammable liquid in tanks

    Only approved containers and portable tanks shall be used for storage and handling of flammable liquids. Approved safety cans or Department of Transportation approved containers shall be used for the handling and use of flammable liquids in quantities of 5 gallons or less, except that this shall not apply to those flammable liquid materials which are highly viscid (extremely hard to pour), which may be used and handled in original shipping containers. For quantities of one gallon or less, the original container may be used, for storage, use and handling of flammable liquids.
