What is the pressure specification for medium-pressure nitrogen in everyone’s factory?
Thread Content
Please ask a moderator for help； Actually, I want to conduct a survey and make a comparison to find out what the specifications for medium-pressure nitrogen in factories are To avoid duplicate counting, we ask everyone to indicate the name of their factory (you can write the city instead if privacy is a concern) ； It is best to indicate the category of the plant (such as petrochemical, refining, aromatics, etc.). The medium-pressure nitrogen referred to is usually the kind used during operation or on a continuous basis; such nitrogen generally falls within the range of (2.0~4.0 MPag). Please help with the statistics. Posts and votes are welcome.
In our refinery, the nitrogen system pipelines have only two pressure levels: 2.5 MPa and 0.7 MPa.
Medium pressure is 2.5MPA, and low pressure is 0.85MPA
Our factory has a 25-kilogram nitrogen gas pipeline network
In our small chemical plant, the highest pressure reached by any of the equipment is 650 KPa; therefore, we have defined that high-pressure nitrogen has a pressure of 7 kilograms (which is similar to the pressure of compressed air), while low-pressure nitrogen has a pressure of 1.7 kilograms.
We have two types of nitrogen systems here: 0.7 and 1.3 Mpa!
We commonly use nitrogen for purging. 1. The standard nitrogen cylinder has a capacity of 40L； 0.04m3.。 2. The gauge pressure of a standard nitrogen cylinder is 13 MPa. (Generally 12.60 MPa)
Those in the fine chemicals industry use gas cylinders as the purging gas, which eliminates the need for nitrogen production and related pipelines
