"Process design is the choice and sequencing of units for desired physical and/or chemical transformation of materials."
The creation of a plan or blueprint for a chemical process.
Process flow diagrams: A systematic representation of the overall process that includes the equipment, instruments, controls, and piping of a chemical plant.
Material and energy balance: A systematic method for accounting the mass and energy flow in a chemical process.
Chemical thermodynamics: The study of the energy and heat associated with chemical reactions, and their relation to the thermodynamic properties of materials.
Heat transfer: The study of the transfer of heat energy between different mediums, including solids, liquids, and gases.
Mass transfer: The study of the movement of materials between phases, such as the transfer of dissolved solids from a liquid to a gas.
Fluid mechanics: The study of the behavior of fluids, including gases and liquids, when they are in motion.
Chemical reaction engineering: The study of the design and optimization of chemical reactors, which are used to convert raw materials into finished products.
Process control: The study of the techniques used to maintain the desired operating conditions in a chemical process, including feedback control and instrumentation.
Process safety: The study of safety protocols and procedures designed to minimize the risks associated with chemical processes.
Economics and optimization: The study of the economic factors that influence the design and operation of chemical processes, including the cost of raw materials, energy, and labor, as well as the optimization of process design to reduce costs and increase efficiency.
Process modeling and simulation: The use of computer models to simulate and optimize the operation of chemical processes.
Process equipment design: The design, selection, and sizing of equipment needed for a chemical process, including pressure vessels, pumps, and heat exchangers.
Process integration: The integration of different processes or stages of a process to improve efficiency and reduce environmental impact.
Environmental regulations and sustainability: The study of regulations relating to pollution prevention and control, and the design of processes that minimize their environmental impact.
Batch process design: This process involves producing a fixed quantity of product at a time in a single batch. It is characterized by its repetitive cycle and the absence of any equipment, such as pipes or tanks, that would connect it with other units.
Continuous process design: This process is used to produce a continuous flow of product. The production rate is usually constant, and the process is characterized by equipment that connects to other units to create a seamless flow.
Semi-continuous/batch-continuous process design: This process is designed to produce large quantities of product in batches, with the output being continuous. Semi-continuous processes tend to be more flexible than continuous processes and can be adapted to meet changing production needs.
Hybrid process design: This process combines the advantages of both batch and continuous processes. It often incorporates semi-continuous or batch-continuous processing equipment in combination with continuous production units.
Chemical looping process design: This process uses a solid carrier to transport reactants between reactors. The process involves a continuous circulation of the carrier material between reactors, which can lead to higher efficiency and lower emissions.
Modular process design: This process is characterized by the use of pre-made modules that can be easily combined to create a customized process. Modules can be added or removed depending on production needs or changes in production requirements.
Flexible manufacturing process design: This process is designed for companies that need to produce a wide range of products to meet changing customer demands. The process involves a high degree of automation and can quickly adapt to changes in production needs.
Green manufacturing process design: This process is focused on reducing the environmental impact of production. It involves using renewable energy, minimizing waste, and reducing the use of hazardous chemicals.
Material recovery process design: This process is designed to recover valuable materials from waste streams. It involves separating and purifying the desired components of the waste stream and can be used to produce a range of products.
Nanoparticle synthesis process design: This process involves the production of nanoparticles, which have unique properties and can be used in a range of applications. It requires specialized equipment and involves precise control of process parameters, such as temperature and pressure.
"Process design is central to chemical engineering, and it can be considered to be the summit of that field, bringing together all of the field's components."
"Process design can be the design of new facilities or it can be the modification or expansion of existing facilities."
