Let’s discuss the responsibilities of the process engineering field

I have been working in static equipment design for many years; in the past few months, I have heard opinions from people in the process engineering field that differ from my previous understanding. I would appreciate it if everyone could share their views. The process says: 1. The equipment diagrams in the process data sheet are drawn by the equipment specialists, and then the process details are added to the data sheet. (I’m hearing for the first time that this diagram needs to be drawn for the equipment.) 2. The nominal diameter and tangent distance of vertical or horizontal storage tanks are determined by using the volume specified in the process requirements to calculate the dimensions, which are then fed back to the process team, who enters them into the data sheet. (Does the process team not need to consider the layout?) 3. Doesn’t the process engineering field require basic skills in reading drawings? I heard that schools no longer teach this either, let alone simple drawing techniques (is it true that in the case of professional reviews for equipment engineering drawings and construction plans, the process engineer only needs to sign off, without having to recheck other important dimensions)? ）
The process team needs to implement PID control, providing various parameters to the downstream teams; those teams then use these parameters to create diagrams and provide feedback to the process team
Do the condition charts in the data sheet for raising funds also need to be created by equipment?
As a person in the process engineering field, I truly despise you people in process engineering. While the division of tasks may vary among different companies, it’s absolutely impossible for everything to be handed over to the equipment specialists, as the original poster suggested. 1: Nonsense; the schematic diagrams should be drawn by professionals in the process engineering field. The dimensions of the equipment and the design of its internal components (which may also be designed by the suppliers) all fall within the scope of process engineering. Since I am not an expert in equipment, my understanding is that the field of equipment engineering focuses on issues related to structural reliability. II: It’s still nonsense. The dimensions of such equipment are determined by the manufacturing process; what does that have to do with the equipment itself? Even if the storage tank is simple, it’s not sufficient to consider only its volume. As the original poster said, factors like layout also need to be taken into account, not to mention operational aspects and the technical requirements for the pipe connections. In short, once the diameter of the equipment is determined, what’s the point of discussing other conditions related to the pipe connections? Do we really have to go back and forth several times for just these process conditions? Three: Normally, during the study period, there is a course in engineering drawing, and it is essential to be able to understand the drawings used in the equipment field. Co-signing is the final step to confirm whether the drawings for the equipment section meet the required conditions; it’s not just a matter of signing.
There are specialized areas of expertise. The process engineering field is responsible for formulating questions, while equipment is used to solve problems. Just like between diners and chefs, which one is more important?
In short, process delegation must enable downstream specialists to correctly understand the intent of the process and achieve its objectives. If no specific requirements are stated for the process, it is assumed that there are no such requirements, as long as the work done does not violate the requirements specified in the process assignment.
The condition diagram is drawn by the process engineering team; the size of the equipment, the size of the pipe connections, and the type of key pipe connections (such as those with inserts) must all be specified in this diagram. The operating temperature, pressure, and material specifications are also indicated. Once the condition diagram is available, the equipment diagram is drawn. Any elements that are not included in the condition diagram are added and reported back to the process engineering team – for example, if safety valves are required for equipment calculations but were not mentioned in the initial diagram, they need to be added.
In other words, just like in the case of domestic refineries, it is reasonable for the owners of such refineries to provide a rough estimate, while leaving the decisions regarding equipment, electrical systems, controls, and civil works to the equipment manufacturers
Currently, the process design work is in progress: Phase 1 involves drawing schematic diagrams and other related illustrations, along with determining preliminary dimensions; the equipment team is responsible for conducting a second review. II: The openings on the equipment, such as those at the pipe ends, are created in accordance with the requirements specified in the process specifications. Three: Process engineering drawing is relatively simple; if one doesn’t know CAD, how can drawings be created? And how are plans and technical modifications prepared on a regular basis?
