The design technical requirements for air separation units must be practical and innovative!
Thread Content
I started a thread earlier asking what kind of air separation plant people would like to build; the question might have been too general, so I’m starting another thread to discuss the technical requirements! With the rapid pace of technological development these days, and different companies having their own approaches to on-site applications, what kind of comprehensive and thorough technical requirements would you, as a buyer, put forward to the seller?
One-click start brings about the hazards, while one-click stop eliminates them. If I were the buyer, I would prioritize ensuring three key aspects: 1) When choosing refrigerated containers, opt for those from reputable and well-regarded manufacturers at reasonable prices; moreover, it’s important to specify certain equipment and valve manufacturers to ensure reliability. 2) For the compressor, choose an imported one that is reliable, has low energy consumption, and is reasonably cheaper among imported equipment. Such as air compressors, nitrogen compressors, liquid pumps, and expanders. 3) Selection of the installation unit: Choose one with a track record and experience in installations.
High~! Big~! Up~! This is the true spirit of having ideals and ambitions; this will be our ultimate goal. If one day large-scale devices can reach this technical level, then we will be free!
Yes, this is the same approach we follow when selecting equipment for air separation operations; however, there are also some non-market-related factors at play! 1. For cold boxes, domestic manufacturers offering models priced at over 50,000 are generally of good quality, with solid performance in operation and a high cost-performance ratio. There should be no major issues as long as the owner insists on specifying particular equipment and valve manufacturers; however, interference from a very small number of individuals with selfish motives may occur ； 2. When selecting a compressor, if one wants a reliable unit with low energy consumption, the only option is to go with an imported one. For the air compression units of the 60,000-class I’ve seen, those imported models have a steam production capacity of around 130 T/h, while domestic ones require 150 T/h or more, sometimes even reaching 180 T/h. But if low energy consumption is a priority, don’t expect low prices! At the same time, as long as it can be done domestically, the issue of local production also needs to be taken into consideration! 3. As for the installation unit, there’s nothing to say about it. The stable operation of the equipment in the future, especially for moving components such as compressors, depends directly on the quality of the installation. This requires the staff on the client’s side to be conscientious at the installation site, to raise any issues that need to be addressed – without being afraid of hassle, after all, it’s equipment that will be used by them!
As the owner, I think there is another key point: hire experienced personnel in process engineering, equipment, instrumentation, and electrical systems during the early stages of installation, so that they can use their practical operational experience to make preliminary modifications that will facilitate future inspections, maintenance, and energy savings. This allows the issue to be resolved during construction and installation, saving costs on future renovation projects. It is especially a benefit for future operators, as it will **reduce the workload and intensity of work.
This is necessary; which property owner who doesn’t understand air separation would dare to start from scratch on their own? It’s essential to enlist technical experts with practical experience to work together on the project!
Yeah, this nitrogen generator can also be used for two purposes; the oxygen-rich exhaust gas can be recycled. Lol, introducing oxygen-rich gas into the combustion boiler improves combustion efficiency and reduces costs. (I’m just giving some simple suggestions, hehe~~) If you’re interested, feel free to reach out to me
Cheap and efficient, with an emphasis on the company’s qualifications and the competence of its staff (technical skills and sense of responsibility)
The original poster is referring to perfect conditions, but since the efficiency is high, the cost will be high as well. It’s like imported devices versus domestic ones: although they are more expensive, their efficiency is definitely higher than that of domestic devices! Since a lot has been said in general terms, let’s discuss the specific details (such as the optimized design of air compressors, pre-cooling, purification, distillation, and backup liquid systems). In other words, these are the design technical requirements mentioned in the title – please share your thoughts!
Assembled machines are still not as good as branded ones.
