Abstract
This column includes at least one exchange section (5, 9, 10, 11) defined between an associated upper liquid distributor (4, 6, 7, 8) and a lower fluid inlet/outlet (21, 23) or an associated lower liquid distributor (7, 8), the exchange section including an upper portion (5A, 9A) and, under it, another portion (5B, 9B, 10B, 11B) preferably of the conventional type. The upper packing portion of at least one packing section includes a packing module having less transfer units than a packing module of the conventional packing portion of the same section. Application to double columns for air distillation.
Claims11
A packed column for exchanging heat and/or mass between descending liquid and a rising gas, comprising:
- at least one exchange section defined between an associated upper liquid distributor and one of a lower inlet/outlet for fluid and an associated lower liquid distributor,
- said at least one exchange section comprising an upper portion and another portion below said upper portion, each of said upper portion and said another portion comprising at least one structure packing module, wherein said structured packing module of said upper portion has a number of transfer units less than that of said structured packing module of said another portion and structure different from that of said structured packing module of said another portion.
A packed column for exchanging heat and/or mass between a descending liquid and a rising gas, comprising:
- an exchange section between an associated upper liquid distributor a one of a lower inlet/outlet for fluid and an associated lower liquid distributor,
- said exchange section comprising an upper packing module with cross-corrugated packings that receives a liquid directly from aid upper liquid distributor and a lower packing module with ventilated packings below said upper packing module, wherein said upper packing module has a number of transfer units less than that of said lower packing module.
