Hydrate formation conditions of (CH_4+CO_2+H_2S) ternary sour natural gases;

This worldwide well-known standard was widely accepted as the guidelines in steel materials selection for sour natural gas environment.

With a large number of developing sour natural gas fields at home and abroad in recent years,many researchers take extra attention to prevenl hydrate plugging problems.

According to the documents provided by ISO/TC193, it also introduces scope of natural gas property determination, structure of standard document, installation of instruments, sampling criterion, and standardization program for instruments used for determination.
