n-Butane - Bulk
C4H10
n-Butane is separated from a natural gas stream by absorption in a light oil. It is then stripped along with propane as liquefied petroleum gas (LPG) and separated by fractional distillation: n-butane boils at -0.5° C (31.1° F)
It is filled into T50 ISO containers for international transport as well as road trailers and rail cars. ISO Containers are approved by UN, RID/ADR, CSC, AAR-600, DOT, TC, TIR, UIC.
