Polaris has developed a process for the purification of gases at low temperature, based on distillation in two columns in series (one for more lighter compounds and the other for heavier compounds). The process is continuous and completely automated. The system can be combined with several typologies of pretreatment, depending on the pollutants to be removed preliminarily.
In this particular case the customer wanted to upgrade the natural gas available in standard commercial grade. Polaris specialist developed a customized solution for the production of ultra-pure gas with the flexibility to operate even for less pure outlet. Details on outlet grades and operating conditions are described in the pdf file
Key figures: High purity of outlet gas
