KDON Air Separation Unit Plant Oxygen Nitrogen Generating Plant China Greenfir

Greenfir is a professional natural gas processing, liquefaction plant, air separation unit, heat exchanger, reciprocating piston compressor, cryogenic cold box, fractionating column manufacturer and solutions provider with ISO 9001: 2015, ISO 14001: 2015, ISO 45001: 2018 and ASME U certified.

Greenfir has successfully designed, manufactured and delivered more than 300 sets of natural gas purification, liquefication plants, air separation units, CNG filling stations, cryogenic cold box, etc. all-around China, Middle East, Central Asia and Southeast Asia, etc. We can deliver skid-mounted solutions customized to meet client's challenges and requirements (including adverse weather conditions, transportation and plot area limitations, etc.).

We treat all the cryogenic solutions with serious attitudes and professional experience. Combined with our knowledge and experience, Greenfir provides each client with a technology-leading solution you can count on and bring a wider range of options and more profits.

Cryogenic air separation plants utilize a low-temperature rectification process to produce oxygen, nitrogen, and argon. These plants can generate gaseous products for pipeline distribution or cryogenic liquids for delivery by truck or for storage.

Greenfir provides expertise to design and manufacture world-class, cost effective, custom-built air separation plants. We will work closely with your project team to help accurately define the ideal scope for your Nitrogen, Oxygen or Argon project. Expert designers will help narrow your options through a series of engineering and cost optimization steps. We will help you arrive at the right-sized, right-priced solution that can meet your delivery and start-up schedule. 

Most noteworthy, liquid air separation plant pioneers the trend of future development. Because liquid products are easy for quality control, storage, and delivery. In addition, they also work with higher efficiency. Therefore, the liquid air separation unit will probably be favored by more and more users. 
Moreover, our experienced technical team will propose the most economical solutions that best meet your requirements. Furthermore, the O2 and N2 yield can either be gas or liquor. Most of all, when the output is large enough, you will consequently get the highly profitable by-product-argon gas or liquid argon.

Since establishment, we designed and produced more than almost 20 different sets of air separation plants. Especially relevant, they all feature reasonable workmanship and small power consumption, high efficiency, and stable performance.Note: Those two pictures show the site of the nitrogen generation package project which delivered by Greenfir.
 O2 output: 600 ~ 60000 Nm3/h
O2 purity: 99.6 %
N2 output: 600 ~ 60000 Nm3/h
N2 purity: 99.999 %
In addition, pressure is customized as required.Note: Inner compression and Outer compression are available for the above sizes. 

Different Types of Air Separation Units (ASU)
All gaseous product
On site gas generators are by far the most common type of ASU. These plants can produce Oxygen only, Oxygen and Nitrogen or Oxygen, Nitrogen and Argon or just Nitrogen. In all cases the gases that are not fully purified are used for refrigeration and vented to atmosphere. These units separate the air in liquid form, but utilize the refrigeration from the liquids before they exit the coldbox. The products come off the coldbox at fairly low pressure and ambient temperature. Product compressors are then used to increase the products to required header pressure. In some processes, liquid products are pumped through the main heat exchangers where they are warmed to ambient temperature at the required pressure. Gas generators typically produce between 10-2000 short tons of combined product.
All Liquid Product
This is normally considered a merchant plant. All desired product is liquefied for shipment in cryogenic transport trailers or rail cars. Generally, these units make liquid Oxygen (LOX), liquid Nitrogen (LIN) and liquid Argon (LAR), though in some oil/gas production areas there are large liquid Nitrogen only ASUs. These products are delivered into cryogenic tanks at the users site, where it is either warmed back to a gas before use or used as a liquid. Typically the only users that utilize liquid products are food freezers, oil field service companies or other processes that require very cold temperatures.
Liquid plants are typically sized to produce from 150 to 1000 short tons per day of combined product. These ASU's have an additional section of equipment called a Nitrogen Liquefaction Unit (NLU) to provide the necessary refrigeration to liquefy all products. The NLU is generally the largest power user by far in an ASU.
Combined Liquid and Gas Product
Commonly called "piggyback plants," these ASUs produce mostly gaseous product for pipeline use, but also have NLU's to produce liquid products for shipment off site.

Therefore, if you need a set of air separation plant, maybe you can probably tell us your specific requirements and environmental parameters so that we can make professional quotations accordingly.
Please advise:
1. First of all, altitude, temperatures (highest temperature in summer and lowest temperature in winter) and humidity, earthquake intensity and wind speed;
2. Moreover, voltage including high voltage and low voltage;
3. In addition, your requirements on the output and purity of liquid oxygen or oxygen gas that are as indicated below:
