Objective
The purpose of this project is to develop a system able to bring an innovative technological solution to problem of two-phase mixture compression on sea-production chains. This problem is solved presently by static separation which weight and volume generate important costs.
Taking into account this techno-economical aspect, it seems that the two-phase centrifugal compressor including a two-phase dynamic separator should replace progressively the present static separators, all the more so as the development of screw compressor, the concurrent technology, has not yet been completed. Consequently, the development of the two-phase centrifugal compressor which of course strongly depends on the development of its static separator, is a very profitable investment.
Satisfactory mechanical operation. High separation efficiency. Misfunction of the liquid collecting system which should be thoroughly redesigned.
The present project deals with the hydrodynamical and mechanical design and the qualification of the two-phase dynamic separator on an experimental air-water apparatus. This separator will have to treat very high massic liquid rates (up to 50 %), under high efficiency separation objectives (down to 7 micro m).
The liquid phase is supposed to be in a mist flow configuration, assuming that liquid slugs or plugs can be erased before the separator by specific system. Moreover, the size of solid particles is assumed to be lower that 5 micro m for a maximum concentration of 10(-2g)/m3.
The dynamic separator is a conical-shaped cylinder where the liquid phase is centrifugated and transformed into an annular liquid film which is extracted by a bladed collecting disc.
The development programme is divided into three part :
Part 1 : Detailed design of the two-phase air-water separator model
- Aerodynamical design
- Hydrodynamical design
- Separation study
- Mechanical study
Part 2 : Fabrication of the air-water model
Part 3 : Qualification of the air-water model by laboratory testing
The purpose of this stage will be to check :
- the separator characteristics
- the liquid annular film stability
- the liquid extraction and collecting system (pressure level).
