Can I go to the full liquefied air branch privately?
Thread Content
One of my friends is getting an all-liquid air separation unit: LOX 3800 Nm3/H； It’s a domestically produced LIN2500Nm3/H unit; do such devices have cost advantages? What is the typical power consumption per unit? If I decide to get involved, what technical aspects need to be taken into consideration? Thank you!
It’s not possible to simply say whether there are advantages or not; several factors need to be considered: 1. What is the electricity price like? 2. How are the surrounding markets, and what are the expected liquid prices? 3. Equipment investment details (which are domestic and which are imported, etc.), as well as energy consumption levels. The production costs in a country reliant on machines will be high, leading to higher investment in machine imports. You can’t have both fish and bear paws; a trade-off is necessary.

Other factors to consider include: the ratio of sales of liquid oxygen to liquid nitrogen, the development of sales markets, and the availability of qualified professionals. Additionally, such equipment does not have any advantages in regions like East China and North China. The key factor is substantial financial resources
Geographical location and market share in the regional sales market are key considerations. The other factors (electricity prices, equipment costs, etc.) are secondary.
LOX 3800Nm3/H； The oxygen-to-nitrogen ratio for LIN2500Nm3/H is not very economical; 150 tons of liquid oxygen per day is an excessive amount, and a storage tank of around 500 cubic meters is required. Large gas companies in the East China region face significant pressure in terms of liquid gas sales, and most of their equipment is imported from abroad, which results in lower energy consumption. Therefore, there is basically no advantage for private parties. Unless one thing: having a good network of contacts.
The argument presented on the 4th floor cannot be accepted; if your costs are high, how can you achieve a market share? Only by having a cost advantage can one win in competition.
For air separation equipment, I’ve seen that foreign-made units offer better separation performance than domestic ones. As a quality inspector, when analyzing industrial oxygen, domestic equipment can only produce oxygen with a purity of 98%, while foreign equipment can achieve a purity of over 99.5%. In other words, when adhering to GB/T3863--1995 standards, domestic equipment is considered substandard, whereas foreign equipment is classified as first-class. These are two sets of equipment in a factory, and the workers’ skill levels are quite similar
For this air separation setup in Liaoning, the equipment is supplied by Suoyang, while the compressors are from Atlas. According to my friend, the manufacturer calculates the power consumption at 0.8 kWh per liter of liquid. I’m not sure if this figure is reliable
Suyao has strong technical capabilities! Give it a like!
The energy consumption is fairly acceptable, but it’s almost impossible for the manufacturer to guarantee what it will be during the summer.
It’s better not to use domestic equipment for the main devices; the benefits should be significant
Fosda Gas Equipment Company is also good; it already has several fully liquid air separation units in operation!
Our energy consumption for liquid air separation is around 0.73 KW/L of liquid!
I think the key is to have good relationships with market sales representatives; otherwise, there won’t be any advantages. With a solid sales network, one can provide services to factories that need air separation equipment.
