ASME Oxygen Nitrogen Gas Plant Cryogenic Air Separation Unit 99.999% LAr

Oxygen Nitrogen Gas Plant | Cylinder Filling Oxygen Gas Plants

nitrogen gas plant

Part 1. Main descriptions

This plant operates on a low pressure cycle and is used to produce pure oxygen and nitrogen from air by means of cryogenic rectification. The feed air is first liquefied by the refrigeration produced by turbo-expander and then rectified for two times on the basis of the different boiling points between liquid oxygen and liquid nitrogen. As a result, oxygen at a purity of over 99.6% and nitrogen at a purity of over 99.99% can be obtained from the plant. If required, the plant can also produce liquid oxygen and liquid nitrogen partially by means of modified operation.

Part 2. The basic Principle

The basis principle of air separation is to use the different boiling points of the components of liquefied air to separate them. To this end, the air separation plant consists of the following process:

1. Filtration & Compression

2. Purification

3. Cooling Air to Liquefaction Temperature

4. Refrigeration

5. Liquefaction

6. Rectification

7. Hazardous Substance Removal

Process of Cryogeic Storage Tank

Part 5: Relevant FAQs of ASU

Q1: I want to buy air separation Oxygen liquid Nitrogen liquid and Argon liquid. Pls send me price?/I am interested in your air separation plant, pls send all your specification to me. Pls give me the proposal of all your air separation plants.

Re: We really appreciate your enquiry on our air separation plant. In order to provide you the right plant, we need to get more information from your side. Pls check the attachment and fill in the air separation plant questionnaire, which will help our engineer to know more about your specified requirement.

Q2: Do you have customers in our country?/ Have you ever sold the plant to our country?

Re: Yes, we have already sold several sets to your countries. However, we all sold them to the agents, so we don’t know which company exactly use our plants. Enclosed you can find small parts of our customers reference. If you come to visit our factory, we will take you to visit our customer’s site.

Q3: Does your quotation include installation cost?

Re: Actually, our quotation excludes the installation cost. However, we can send engineers to guide you do the live installation and also the commissioning. Your side needs to be responsible for the engineer’s round-trip air tickets, traffic fee, food, communication, insurance and accommodation. Besides, there will be 200USD allowance per day for each person by your side.
