Definition of Distillation: Distillation is a separation process that involves heating a liquid mixture to create vapor and then cooling the vapor to obtain a liquid. The process exploits differences in boiling points of components in the mixture to achieve separation. Objectives of Distillation: Separation of Components: To separate a mixture into its individual components … Read more
Principle of Steam Jacketed Kettle: Uses steam to provide uniform heating to the contents within the kettle, typically for cooking, mixing, or concentrating solutions. Construction of Steam Jacketed Kettle: Kettle: Typically made of stainless steel, with a hemispherical bottom to ensure even heat distribution. Jacket: A double-walled structure around the kettle where steam is circulated. … Read more
Principle of Climbing Film Evaporator: Utilizes the principle of forming a thin film of liquid that climbs up the walls of a heated tube, enhancing evaporation due to increased surface area and reduced film thickness. Construction of Climbing Film Evaporator: Vertical Tubes: Long, vertical tubes where the liquid forms a climbing film. Steam Jacket: Surrounds … Read more
Principle of Horizontal Tube Evaporator: Uses steam to heat a liquid inside horizontal tubes, causing the solvent to evaporate and leaving a concentrated solution. Construction of Horizontal Tube Evaporator: Shell: A large cylindrical container housing the tubes. Tubes: Horizontal tubes within the shell where the liquid to be evaporated flows. Steam Chest: Surrounds the tubes, … Read more
Hormones Introduction: Hormones are chemical messengers produced by endocrine glands that are secreted into the bloodstream to regulate various physiological processes in the body. They play a crucial role in maintaining homeostasis, growth and development, metabolism, reproduction, and stress response. They act on target cells or organs that have specific receptors for these hormones. This … Read more
Evaporation vs. Boiling: Evaporation: Occurs at any temperature below the boiling point, typically at the liquid’s surface. Boiling: Occurs at a specific boiling point throughout the liquid, with bubbles forming within the liquid. Evaporation vs. Distillation: Evaporation: Primarily focuses on removing a solvent, usually without condensing the vapor. Distillation: Involves vaporizing a liquid and then … Read more
Heat Interchangers and Heat Exchangers are terms often used interchangeably, but they typically refer to the same concept: devices that transfer heat between two or more fluids. Heat Interchangers Terminology The term “heat interchanger” is less common. It typically refers to a device specifically designed for exchanging heat between process streams within an industrial setup, … Read more
Evaporation is a process where a liquid is converted into vapor, typically by heating, and then separated from the remaining liquid phase. This is widely used in various industries for concentrating solutions, drying materials, and recovering valuable substances. Objectives of Evaporation Concentration: Increasing the concentration of a solute in a solvent by removing the solvent. … Read more
Fourier’s law of heat conduction states that the rate of heat transfer through a material is proportional to the negative gradient of the temperature and the area through which the heat flows. Mathematically, it is expressed as: $\mathbf{q} = -k \nabla $ where: q is the heat flux (heat transfer per unit area per unit … Read more
Heat Transfer Mechanisms Methods Conduction in Heat Transfer Mechanisms Definition: Transfer of heat through a material without any movement of the material itself. Mechanism: Occurs due to the transfer of kinetic energy between molecules or atoms. Examples: Heat flowing through a metal rod when one end is heated. Factors: Thermal conductivity of the material, cross-sectional … Read more
