I have a simple but common question: in distillation, it’s common to see specifications for the range of application of certain formulas, such as “at medium and low pressures.” What exactly do medium pressure, low pressure, and high pressure refer to in terms of pressure levels?

Same question; I hope everyone can answer the following

Baidu results: For gas pressure classification, low pressure refers to levels below 100 KPa; medium pressure class B is 100 KPa to 0.2 MPa, medium pressure class A is 0.2 MPa to 0.4 MPa; sub-high pressure class B is 0.4 MPa to 0.8 MPa, sub-high pressure class A is 0.8 MPa to 1.6 MPa; high pressure class B is 1.6 MPa to 2.5 MPa, and high pressure class A is 2.5 MPa to 4.0 MPa
