Regarding the engineering design of this project, aside from the luxury control room that has attracted a lot of attention within the industry, there is also a design that appears restrained and rigid. Have you noticed that? Is it really necessary for the manufacturing standards to be so restrictive and conformist? What’s your opinion? @Fish in the desert
In the cockpit while driving, it’s crowded; 3 tables are fully occupied, with one table remaining empty. 【Haichuan Device Guessing Game】Whose home control room is this? It’s so luxurious and high-class! https://bbs.hcbbs.com/thread-2214098-1-1.html (Source: Haichuan Chemical Industry Forum)
Why can’t the main corridor design be multi-story? The main pipeline is arranged in layers, allowing the expansion bends to be much smaller, which also saves on investment.
In principle, various pipelines can be designed with expansion bends according to their different levels of expansion. However, when they are arranged on the same floor, different types of supports are required, as well as upward bends; in addition, some drainage devices need to be installed. Personally, I think this approach is cleaner – the supports can be shared, and the supports can be designed properly as part of the steel structure
The four control centers for refining, chemicals, aromatics, and ethylene are related to the startup of the atmospheric and vacuum distillation units with initial feedstock feeding; it seems that they have little connection with the latter three.
The round-table console looks too ugly; rows of consoles would be better, as the space in the middle is wasted
As you pointed out, how can different expansion amounts be avoided?
It just looks high-end, imposing, and sophisticated
This amount of expansion is controlled by regulating the distance of the expansion bends in each pipe. Moreover, it is necessary to consider the highest temperature among the pipes – should the pipe with the highest temperature be placed inside or outside the expansion bend?
There are too many pipelines; understanding the inlet and outlet ductwork for these pipelines is a complex matter
