11. These deposits then propagate downstream via a flow separation process , thus developing bedform fields. 12. This results in a better control of the separation process . 13. The drum is the centerpiece of the separator, in which the separation process takes place. 14. Around the same time, new cryogenic air separation processes had been devised independently in Germany. 15. Recent studies have shown that potential improvements are available for cost-saving and effective separation process . 16. He joined Oliphant's University of California, where they worked on the electromagnetic isotope separation process . 17. However, this drum could be completely eliminated if the evaporation separation process was avoided altogether. 18. The collar of the cap is protecting the user during the needle separation process . 19. "It's part of the separation process , " says Osherson. 20. It is extracted from the natural gas by a low temperature separation process called fractional distillation.
