FAQ
What is the process of Oil & Gas ASU?
An air separation unit (ASU) uses the conventional multi-column cryogenic distillation technique to produce O2 from compressed air at high purity and recovery rate. ASU's energy consumption is related to recovery since it is linked to the air flow required by thermal power.
What is an asu unit?
An Air Separation Unit (ASU) is an industrial facility used to separate atmospheric air into its primary components (namely nitrogen, oxygen, and, in some cases, argon and other rare gasses).
What is asu in hydrogen?
Together with nitrogen from the air separation unit (ASU), hydrogen is needed to produce ammonia. Ammonia is mostly used to produce fertilizers, which is one of the most important commodities for food production.
