What does process design do?

Determine the process flow and draw a PID diagram； Material balance, draw a PFD diagram ； Equipment selection and preparation of process equipment list ； The preliminary equipment layout plan is submitted to the piping team ； Design requirements are submitted to the relevant specialized teams, such as those related to instruments for controlling temperature, pressure, and flow rate, electrical requirements, consumption levels for water, electricity, gas, and steam, as well as air conditions in the facility. Various design requirements are also provided to other specialized teams to ensure the smooth progress of the project. There is a lot of work involved in the process, especially during the preliminary design stage. This post was last edited by fanxh on 2009-2-12 08:18]

The processes are divided into very detailed categories, with many different specialties~~~ I’m most envious of chemical engineering – it involves constant calculations, without the need to be on site

The process engineering discipline can be regarded as the main discipline for a design or a project; it serves as a leading discipline that coordinates and oversees other disciplines to carry out the design. Specifically, the main tasks of process engineering include calculations such as material balance and energy balance, and based on these calculations, a Process Flow Diagram (PFD) is created； Draw process piping and instrumentation diagrams (PID) ； Complete the calculation and selection of the main process equipment, determine the specifications for these devices based on the calculation results, and submit design requests to the relevant downstream departments.

The poster probably wants to find a job in the field of craftsmanship; it depends on what kind of organization you join. If you join a large engineering company, the processes will be divided into very detailed categories. If you work at a smaller design firm, the division isn’t as detailed; you’ll have access to everything related to processes. Take a project as an example: 1. First, it is necessary to prepare a feasibility study report for the project, and at this stage the involvement of relevant specialized fields is required; the process design needs to specify requirements for fields such as equipment, architecture, structure, HVAC, plumbing, electrical systems, instrumentation, economic analysis, and general layout ； 2. Complete the preliminary design of the project ； 3. Carry out the construction drawing design for the project. The tasks to be completed here include drawing process flow diagrams, then formulating equipment layout plans, and providing construction drawing requirements to relevant specialties (such as equipment, architecture, structure, HVAC, plumbing, electrical, instrumentation, etc.). In short, process engineering is a complex field that requires learning a great deal; it is not easy to become an excellent process engineer.
