Introduction

Chemical engineering is a discipline of engineering that investigates the operation and design of chemical plants, as well as production techniques. Chemical engineers create commercial processes for converting raw materials into useful items that are both cost-effective and efficient. Chemical engineering principles are used by chemists, physicists, mathematicians, biologists, and economics to efficiently use, manufacture, design, transport, and transform energy and materials. Chemical engineers work on a wide range of projects, from small-scale laboratory research with nanotechnology and nanomaterial’s to large-scale industrial processes that convert chemicals, raw materials, live cells, microorganisms, and energy into useful forms and products.

Chemical engineers work on a variety of aspects of plant design and operation, including safety and hazard assessments, process design and analysis, modelling, control engineering, and chemical reaction engineering. A bachelor's degree in chemical or process engineering is normally required of chemical engineers. Practising engineers must have professional accreditation and membership in a professional organisation. The Institution of Chemical Engineers (IChemE) and the American Institute of Chemical Engineers are two such organisations (AIChE). To varying degrees, a degree in chemical engineering is directly linked to all other engineering fields.

Plant design and construction

Chemical engineering design comprises creating blueprints, specifications, and cost estimates for pilot plants, new plants, and plant modifications. Many design engineers work as consultants, designing factories to meet their clients' needs. Design is constrained by a variety of factors, including funding, government regulations, and safety considerations.

These constraints define the factory's approach, materials, and equipment. Plant construction is coordinated by project engineers and project managers, depending on the size of the expenditure. As a project engineer, who requires further training and skills, or as a consultant to the project group, a chemical engineer can work full-time or part-time. Chemical engineers can operate in a variety of roles, including project engineering, which is one of the most prevalent.

Process design and analysis

A chemical engineering unit operation is a physical phase in a single chemical engineering process. To prepare reactants, filter and separate their products, recycle unspent reactants, and manage energy transfer in reactors, unit operations are used. A unit process, on the other hand, is the chemical equivalent of a unit operation. Unit processes, along with unit operations, make up a process operation. Materials are converted via biochemical, thermochemical, and other methods in unit processes. Process engineers are chemical engineers who are in charge of these.

The types and sizes of equipment, as well as how they are connected and the materials used in their construction, must all be defined as part of the process design. A Process Flow Diagram, which is used to control the capacity and dependability of a new or existing chemical industry, is frequently printed with details.

Chemical engineering education begins with a bachelor's degree. The principles and techniques of process design are emphasised throughout the course of three or four years of study. Existing chemical facilities employ the same techniques to assess efficiency and provide recommendations for improvements.

Transport phenomena

Many industrial applications need the modelling and study of transport phenomena. Fluid dynamics, heat transfer, and mass transfer are all affected by momentum transfer, energy transfer, and chemical species transport, which are all governed by momentum transfer, energy transfer, and chemical species transport, respectively. Separate considerations for macroscopic, microscopic, and molecule level events are common in models. Modelling transportation phenomena thus necessitates a working knowledge of applied mathematics.
