CHEMICAL ENGINEERING IS AN ENGINEERING DISCIPLINE WHICH STUDIES THE DESIGN AND OPERATION OF COMMERCIAL-SCALE CHEMICAL PROCESSES IN SAFE, SUSTAINABLE, AND PROFITABLE MANNERS. THESE PROCESSES ENCOMPASS VARIOUS PROCESSING STEPS UTILIZING CHEMICAL AND BIO-CHEMICAL REACTIONS, AND CHANGES IN PHYSICAL AND CHEMICAL PROPERTIES OF MATERIALS TO CONVERT THEIR PHYSICAL STATE, ENERGY CONTENT, AND/OR CHEMICAL COMPOSITIONS, RESULTING IN VARIOUS COMMERCIALLY VALUABLE PRODUCTS.

IN THE DESIGN OF CHEMICAL PROCESSES, CHEMICAL ENGINEERS TRANSFORM LABORATORY-SCALE CHEMICAL REACTIONS INTO COMMERCIAL-SCALE PRODUCTION PROCESSES BY DETERMINING THE SEQUENCING OF MAJOR PROCESS OPERATIONS, CALCULATING THE MATERIALS AND ENERGY FLOW BETWEEN THESE OPERATIONS, SELECTING THE PROPER TYPE AND SIZE OF EQUIPMENT TO PERFORM THESE OPERATIONS, CALCULATING THE REQUIREMENTS FOR PROCESS UTILITIES, AND DEVELOPING A LAYOUT OF THE PROCESSING FACILITY. CHEMICAL ENGINEERS ALSO MAKE EFFECTIVE USE OF ECONOMIC PRINCIPLES TO EVALUATE THE PROFITABILITY OF A PROCESSING FACILITY.
