Description
5.8.83 Bo/eh Phase separator for two phase mixture in annular flows The present ;nvention relates to a phase separator according to the preamble of Patent Claim 1.
In many fields of use, such as, for example, in steam turbine units, there is the requirement that liquid/
gas two-phase flows must be separated into their two phases.
In steam turbine units, this is especially neces-sary in order to minimise the erosion and corros;on poten-tial of the two-phase mixture, to reduce the pressure drop 1û occurring in the pipes and to avoid hammer in the system.
Quite often, the downstream heat exchangers in a steam turbine unit are unsuitable for the passage of t~o-phase mixture, or the systems are not desîgned accordingly.
In many cases~ such two-phase flows are annular flows, that is to say the liquid phase forms, on the pipe wall, a closed film which completely surrounds the gaseous phase flowing as a core in the ;nterior. The fraction of the wall film in the total liquid mass flow can be up to 80X.
The follo~ing solutions are used in steam turbine units for the phase separation of two-phase mixture in annular flows - installation of simple impingement plates fitting of Pelton wheels - installation of deflection separators - resorting to a cyclone separator.
All these methods share the disadvantage that the phase separation, already effected as such in the annular, flow,does not form the start;ng point for the final sep-arate segregation of the phases; instead, re-entrainment of the liquid phase in the gas flow takes place.
The drops formed are then precipitated, on the one '``~
~.~3~
- - 2 ~ 96/83 hand~ by we;ght forces ~;mp;ngement plates, Pelton wheels) and, on the other hand, by centr;fugal forces tdeflection precipitator, cyclone).
The former solution requires a large widening of the flow cross-sect;on ;n order to reduce the velocity of ;mp;ngement and to reduce the entra;ning power of the steam or gas. The second solution requ;res, in the case of the cyclone, vigorous spinning of the flow, which repre-sents a potential risk to the downstream equipment.
The invention is intended to provide a remedy for - these disadvantages.
The ;nvention, as it is characterised in the claims, is based on the object of no longer mixing the liquid wall-film flow and the gas core fLow in a phase separator of the type initially described. As a result of the most complete separation of the two phases poss ible, only insignificant re-entrainment of liquid and gas ! takes place; the phase separation which already exists in an annular flow is thus exploited for the final separation of the tro-phase m;xture.
It is to be regarded as the essential advantage of the ;nvention that, due to the exploitat;on of the already existing phase separation in the flo~, there is no atom;sation of the liquid wall film to form drops and, for this reason, a large deceleration of the flow velocity and sp;nning are no longer necessary.
Since the gas core flow is deflected and can then flow off parallel to the water trap located below, any back-pressure resulting from impingement of the gas flow on the water surface is avoided.
A further advantage results from the simpl;city and compactness of the structural design of the solution according to the invention: it is thus universally applic-able.
3S Furthermore, the solution can be integrated ;n already existing phase separat;on vessels for ;mprov;ng the operational reliability and effectiveness of the phase separation.

- 2a -According to a broad aspect of the present inven-tion there is provided a phase separator for a two-phase fluid mixture in annular flow. The phase separator comprises an inlet line in which, during use of the separator, a two-phase fluid mixture flows. The liquid phase of the two-phase fluid mixture forms a liquid film on the inner surface of the inlet line moving in parallel lines and the gaseous phase of the two-phase Eluid mixture forms an interior core surrounded by the liquid phase. The gaseous phase of -the two-phase fluid mixture also moves in parallel lines and moves in parallel to the liquid phase. A first ou-tlet line is provided for -the gaseous phase of the two-phase fluid mixture. The first outlet line has an open upstream end sized, shaped, and positioned in fluid communication with the inlet line so that i-t receives substantially only the gaseous phase of the two-phase fluid mixture. The first outlet line is alsoben-t downstream of its open upstream end to carry the gaseous phase of the two-phase fluid mixture away at an angle to the parallel lines in which the -two-phase fluid mixture moves in -the inlet line. A liquid trap is also provided. A second outlet line is further provided for the liquid phase of the two-phase fluid mixture. The second outlet line is parallel to the inlet line and has an open ups-tream end sized, shaped, and positioned in fluid communi-cation wi-th the inlet line so that it receives substantially only the liquid phase of the two-phase fluid mix-ture. The second outlet line also has an open downstream end in fluid communication with the liquid trap, whereby the liquid phase of the two-phase fluid mixture flows from the inle-t line in at least substantially straigh-t parallel lines -to the second outlet line and into the liquid -trap.

- 2b -According to a further broad aspect of -the present invention, there is provided a method of separating the phases of a two-phase fluid mixture in annular flow in an inlet line in which the liquid phase of the two-phase fluid mixture forms a liquid film on the inner surface of the inlet line moving in parallel lines and the gaseous phase of the two-phase fluid mixture forms an interior core surrounded by the liquid phase. The gaseous phase of the two-phase fluid mixture also moves in parallel lines and moves in parallel to the liquid phase. The method comprises the steps of providing a first outlet line for -the gaseous phase of the two-phase fluid mixture. The first outlet line has an open upstream end sized, shaped, and positioned in fluid communication with the inlet line so that it receives substantially only -the gaseous phase of the two-phase fluid mixture. The first ou-tle-t line is also bent downs-tream of its open upstream end to carry the gaseous phase of the two-phase fluid mixture away at an angle to -the parall.el lines in which the two-phase fluid mixture moves in the inlet line. A second outle-t line is also provided for the liquid phase of the two-phase fluid mixture. The second outlet line is parallel to the inlet line and has an open upstream end sized, shaped, and positioned in fluid communication with the inlet line so that it receives substantially only the liquid phase of the two-phase fluid mixture. The second outlet line also has an open downstream end in fluid communication with a liquid trap, whereby the liquid phase of the two-phase fluid mixture flows from the inlet line in at leas-t substantially straight parallel lines through -the second outlet line and in-to the liquid -trap.
Illus-trative embodiments of the subject oE the invention are represented in a simpLified manner and explained in more detail below, by reference to the draw-;ng. Any elements which are not essential to an under stand;ng of the invent;on are not ilLustrated.
In the drawing:
Figure 1 shows a phase separator with a deflected inner pipe;
F;gure 2 shows a phase separator with a straight inner pipe, a s;de opening and roof;ng thereof with baffles, and Figure 3 shows a side view of Figure 2.
The direction of flow of the media is marked by arrows. In the var;ous figures, the same elements are always provided with the same reference numerals.
Figure 1 shows, in a greatly simplified manner, the concept of a phase separator with the phase separa-tion, according to ~he invention, of the two-phase mix-ture.
The annular flow 3 arriving at the inlet branch 1 of a water trap 2 is separated into a gas core flow 4 and a liquid wall film 6 by means of a c;rcular ring pass-age 12 formed by the inner pipe 5 and outer pipe 7.
Whereas the gas core flow 4 flows through the inner pipe 5 and is deflected sideways above the water trap 2, ~he l;qu;d wall f;lm 6 can flow down unhindered. The phases no longer come into contact with one another after the separation of the two-phase mixture. This is also a pre-condition for avoiding the feared re-entrainment. To ensure that carry-over or entrainment of the liquid is really prevented, ;t is an advantage when the sideways deflection is not inclined towards the water trap 2.
Figure 2 is a section through a further illustra-tive embodiment of a phase separator which again is effective in the inlet branch 1 of a water trap 2.
The phase separator consists of an inner p;pe 5 which is closed off by an impingement plate 10 at the end, as viewed in the direction of flow, and which is cut open on one side. This opening 11 ;s roofed by baffles 8 ;n the manner of a gable so that the liquid wall film 6 can ~23~
, - 4 - 96/~3 more easily flow down on the outer periphery of the inner pipe 5 and does not come into contact with the gas core flow ~ issu;ng from the opening 11. On the periphery~
severa~ spacer plates 9 are installed between the inner pipe 5 and outer pipe 7; in some cases, these plates can also be utilised for supporting the inner pipe 5.
Figure 3 is a side view of F;gure 2. This shows how the baffles 8 shield the opening 11 and how the latter ;s roofed in the manner of a gable.
The proposed solutions can be applied in all lines in which annular flows of two-phase mixture prevail. This applies to both water/steam flows and to any liquid/gas mix-tures, such as generally encountered in process engineering~
The different volume fractions of the gas core flow 4 and liquid wall,film 6 can be controlled by appropriate design of the circular ring passage 1Z.
In many fields of use, such as, for example, in steam turbine units, there is the requirement that liquid/
gas two-phase flows must be separated into their two phases.
