Preparation of homogeneous gas mixtures with SF6

摘要: Homogeneous compressed gas mixtures with SF6 and a density at least 4 g/l lower can be prepared by using mixing station the following elements: premixer in which separate gases are brought together; static mixer (F) and/or buffer tank connected thereto; compressor (7) to (6) or (F); when is used, return line (10) from output (6). Mixtures of N2, useful for example as insulating current-conductive underground cables, produced this process, capable processing large flow rates. Mass flowmeters ensure high precision reliability. Also disclosed mobile implementing process.
