Problems solved by technology

In patent applications US 7,559,539 and US 7,559,540, the column section is not divided into packing sections, so its implementation does not prevent lateral displacement of the liquid in all directions under the action of three-dimensional wave motion
Therefore, in offshore environments, these embodiments do not provide good distribution of liquid and vapor phases

Embodiment Construction

[0030] The invention relates to a contactor for a column used for heat exchange and / or mass exchange between two fluids. A contactor is an element that brings two fluids into contact, thereby promoting heat exchange and / or mass exchange between said two fluids. The contactor of the present invention comprises at least one packing layer, the packing layer is at least composed of a first structured packing and a second structured packing, the geometric specific surface area of ​​the second structured packing is larger than that of the first structured packing. According to the invention, in each packing layer, the main direction of the first structured packing is parallel to the main direction of the second structured packing.

[0031] By structured packing is meant a stack of corrugated plates or folded sheets which are organized in large blocks, as described in particular in patent applications FR 2,913,353 (US 2010 / 0,213,625), US 3,679,537 and US 4,296,050. Structured packin...

Abstract

The invention relates to a contactor (3) for a heat and / or material exchange column comprising an arrangement of two structured packings (A, B) developing different geometric surface areas and having parallel principal directions. The invention also relates to a heat exchange column, to a floating structure and to the use of a column equipped with such a contactor.

Description

technical field [0001] The invention relates to the field of offshore gas / liquid contact towers, more particularly to offshore gas treatment, CO 2 Capture, dehydration or distillation units. Background of the invention [0002] Offshore gas treatment with ammonia scrubbing and / or CO 2 The capture unit contains absorption and regeneration towers for liquid or gaseous fluids. These towers work under gas / liquid countercurrent or cocurrent flow conditions, and they are installed, for example, on FPSO (Floating Production, Storage and Offloading) type or FLNG (Floating Liquefied Natural Gas) type vessels, drilling pontoons or offshore platforms. Drilling pontoons also contain distillation or dehydration towers. [0003] These offshore gas treatment and / or CO 2 Columns used in capture and / or distillation and / or dehydration units are generally based on the principle of mass exchange and / or heat exchange between gas and liquid flowing in the column. A contact tower generally co...
