Chemical Engineering Principles for Intensification of Domestic Operations

Many domestic process and methods used for cooking, washing, cleaning involves chemical engineering principles.Chemical engineering is interdisciplinary field in which many mechanical operations, chemistry fundamentals, kinetics, isotherms studies, unit operations and heart transfer operations are involved.Almost all the products which we use in our day to day life are produced by chemical engineering principles.Investigations are carried out to optimize the operations like cloth drying, cooking, and cloth washing by applying chemical engineering principles.This paper discusses the applications of unit operations for optimization of cloth drying, rice preparation and cooking, tea making and other domestic processes. CHEMICAL ENGINEERINGChemical engineering is application of physiochemical principles for transformation of the raw material into product by bringing about change in composition, energy content or physical state by processing it.Almost all the products starting from shaving cream, tooth paste, brush,soap, detergent, cloths, polyethylene bags, plastic, footwear, mattress etc. are prepared by chemical engineering principles.Powerful methodology is core of chemical engineering (1).Chemical engineer analyzes, designs and operates the processes in solid, liquid and gaseous phase (2).This requires strong knowledge of chemistry and physical principles.Process calculation is fundamental subject in chemical engineering which introduces to the chemical engineering processes and unit operations.Material and energy balances with relevant physical and chemical principles are learnt in this subject (3-4).Heat transfer operation and solid fluid mechanical operations are interdisciplinary subjects also covered in chemical engineering (5-7).Chemical reactions are part of many processes.Studies on conversion, yield, reaction mechanism, design of reactor are learnt in chemical reaction engineering (8-9).Environmental engineering in interdisciplinary subject also studied in chemical engineering with focus on industrial pollution control (10). CHEMICAL ENGINEERING IN DOMESTIC APPLICATIONSChemical engineering finds many applications in our daily life.The unit operations and unit processes in chemical engineering along with mechanical operations are part of our life.If we consider our body Abstract: The unit operations and unit processes in chemical engineering along with mechanical operations are part of our life.If we consider our body as a chemical plant then it has all the operations including size reduction, energy synthesis, membrane separations, mass transfer, heat transfer and conveyers.Day to day processes like tea preparation, cooking, cutting resembles various size reduction and unit operations.Tea making is solid liquid extraction, called as leaching.The equilibrium exists between the solute present in the solid phase and liquid phase.The principle of diffusion exists in fragrance, scent, deodorant, mosquito killers.Washing of cloths also involves chemistry.Chemical engineering principles have huge potential in domestic applications.In processing of food grains, rice, chemical engineering principles play very important and significant role.This paper discusses the applications of unit operations for optimization of cloth drying, rice preparation and cooking, tea making and other domestic processes.Intensification refers to increasing efficiency, conversion, yield and reducing the space requirement and cost for the process.Domestic processes can be intensified by using various chemical engineering fundamentals
