Why is the air separation unit at Guangdong Refining & Chemicals assembled on-site instead of using a complete cryogenic tank? Isn’t the entire cold box easier to manage on-site and results in a shorter construction period? Is it because the prefabrication factory of Hangyang Oxygen is too busy? Is it still the overall cold box price that is high? Is it still difficult to transport? ? ? @RedLee_ZZHI @Nut @BookKid @Mighty Ultraman. @The wise are enlightened
The specific choice between on-site assembly and a modular approach depends on many factors, similar to the installation method of pyrolysis furnaces. Factors include: supplier capabilities, road conditions, design capabilities, contractor installation capabilities, on-site lifting capabilities, price, ... etc.
Road conditions are not a factor; 4,000-ton equipment can be brought in directly, as well as those heating furnaces
Perhaps the road conditions at the manufacturer’s outlet are limited.
There are no issues with the roads leading to the factory either; Hangyang has a factory in ZJG, and that’s where Zhejiang Refining and Chemicals conducts its operations
Generally, those assembled on-site are not convenient for transportation
There are no issues with transportation; Guangdong Refining & Chemicals has transported complete heating furnaces before
It’s the transportation problem. Because the materials used for assembly are measured in tons, the transportation methods employed are common and standard. For bulk transportation, special vehicles are required, the transport speed is limited, and traffic police must clear the way to ensure smooth progress. There is an even more cost-effective option, which is to purchase materials locally and prefabricate them on site. The tonnage of the lifting equipment to be used also needs to be taken into consideration; keep things simple to spend less money and get more done.
