【JST-018】One-on-One Q&A Office for the Operation and Maintenance of Air Separation Units
Thread Content
This post was last edited by Firefly on 2015-4-10 08:20. I have 9 years of experience in the operation and maintenance of cryogenic air separation units; I am an oxygen production engineer with expertise in compression processes. Everyone is welcome to participate in the discussion on issues related to the operation and maintenance of air separation units. I will do my best to answer questions; if you are not satisfied with the responses, please post your questions in the Air Separation Technology forum or other relevant sections to seek further solutions! Appendix: Please participate in exchanges and discussions rationally, as even the wisest can make mistakes. I have the right to refuse to answer posts containing aggressive remarks, and I reserve the right to request that the moderators ban such users.
The original poster is such a kind person! Start a thread to answer questions for us newcomers. Everyone should actively reply with support; encouragement and welcome are what matter! Don’t let other districts make fun of our air separation technology district.
It generally refers to the pressure after the air compressor, that is, the pressure in the lower tower. Currently, this pressure is usually 0.5 MPa, and it is referred to as full low pressure. The lower the pressure, the lower the energy consumption
Bro, things are serious here. Our empty partition has always been very active, and the moderators are also very active (me excluded), hehe.
First, welcome! As for responding to questions from other users, you need to click on the reply corresponding to their floor and then provide an answer; that way, they will be able to see it in the notifications (I will observe for a while; if your response is positive, the post will be highlighted and pinned.)
I would like to ask if there are any registration certificates or similar things that one can obtain in the field of oxygen production
Bro, you made a mistake in your operation. You asked this question directly to me; you should ask the original poster directly! Cryogenic Technician!
**The commonly recognized levels are junior worker, intermediate worker, senior worker, technician, and senior technician. In the engineering field, there are assistant oxygen production engineer, engineer, and senior engineer. I have never heard of any certification that requires a national uniform examination like that of a certified public accountant
I have a question for the moderator: Can the opening angle of the inlet guide vanes of an air compressor be reduced indefinitely, as long as it ensures that the compressor does not surge? Does the current of the air compressor increase in a directly proportional manner to the opening degree of the inlet vanes, under the condition of a constant exhaust pressure?
The lower limit of infinitely reducing the flow rate is the surge point of the air compressor. The current drawn by the air compressor is proportional to the flow rate; the greater the opening angle of the guide vanes, the higher the flow rate and the more work is done. The greater the current.
Does the surge point of the air compressor have to be determined through actual testing? We didn’t conduct this experiment during the testing phase; does the original poster have any similar data that they could share?
