Process engineering is the application of synthesis, design, modeling, simulation and optimization to a chemical process using engineering concepts and criteria.

In the development of engineering projects it is important to consider process engineering techniques given the importance in the design of an industrial plant. The activities range from the development of mass and energy balances to the sizing of equipment according to the operating conditions found in the synthesis stage where the optimal process diagram for the operation to be designed is proposed.

Every project consists of stages and process engineering is the most important activity in the initial stages where the process diagrams and operating conditions of the plant to be designed are defined.

In every engineering project, the activities of the process area begin from the analysis of the proposed processing schemes with their respective laboratory tests, once defined, the basic design criteria for the development of block diagrams (BFDs) are carried out with A preliminary balance that serves as the basis for the development of the process diagram and a list of equipment. Once this stage has been approved, the conceptual development of the layout and a technology evaluation study are carried out. The selected process alternative goes through the following tasks.

• Process optimization

• Equipment sizing

• Design criteria update

• Process flow drawings update (PFDs)

• Control philosophy development

• Plant layout update

• Process modeling

• Dynamic simulation

Defined and approved the tasks, proceed with a final process diagram, equipment data sheet, list of engines, OPEX and CAPEX estimation, this procedure is repeated for all project stages (conceptual, basic, and detail engineering)
