Definitions
- the invention relates to a process for the treatment of glycol / water mixtures from the gas production according to. the features of claim 1.
- a glycol / water mixture is added as a conveying aid in order to prevent the formation of hydrates during the conveyance.
- Other additives are so-called corrosion inhibitors and scale inhibitors, which are used to prevent deposits.
- One goal is to recover the aid and additives used.
- One step of the treatment process in the treatment of the glycol / water mixture is the separation of solids that are larger than 0.5 ⁇ m. are in diameter. Such solids result, for example, from natural gas production or the corrosion of the pipeline.
- the object of the present invention is in the Natural gas production to achieve a better separation performance of the solids to be separated.
- a defined separation limit can be achieved by carefully selecting the pore size of the membrane. Solids of the order of 0.1-200 ⁇ m can be separated.
- the glycol-water mixture is processed with a two-stage membrane separation process, the main stream of the concentrate obtained from the first membrane separation process being circulated and a partial stream of the concentrate obtained being subjected to a second downstream membrane separation process.
- a recycling rate greater than 95% is achieved.
- the glycol to be processed (monoethylene glycol, 1,2 ethanediol) /
- the water mixture is first collected in a buffer tank.
- a feed pump 1 conveys the solution via a prefilter 2 to a unit 3 in which the mixture to be treated is mixed
- the membrane separation process is an exemplary embodiment of a microfiltration.
- the microfiltration unit 3 consists of symmetrical membranes, the filter surface being flown parallel to the membrane (cross-flow filtration).
- a circulation pump 4 is assigned to the microfiltration unit 3, which ensures that the membrane of the microfiltration unit 3 is flown with a pressure of 1 to 6 bar.
- the glycol / water mixture flows at a speed of 1 to 5 m / sec. over the filter surface of the microfiltration unit 3.
- the incoming glycol / water mixture is divided into a solids-laden stream, the concentrate 5 and a filtrate stream 6, also called permeate (first filtration stage).
- the concentrate stream 5 contains the particles in an increased concentration, the filtrate 6 is free of it within the separation limit of the membrane.
- the main stream of the glycol / water mixture 5a is circulated via the microfiltration unit 3. This is shown by the arrow.
- the filtrate 6 and a partial stream of the concentrate 5b are removed from the circuit.
- the feed pump 1 delivers as much glycol / water mixture into the circuit as can be removed from the filtrate 6 and concentrate 5b.
- the mode of operation described above is referred to as feed and bleed mode.
- the filtrate 6 is collected in a collecting container 7 in order to be treated in further process steps.
- the partial stream of the concentrate 5b is temporarily stored in a settling tank or fed to a disposal unit.
- a further exemplary embodiment of the method according to the invention is shown schematically in a block diagram in FIG.
- the glycol / water mixture to be processed is also collected in a buffer tank.
- a feed pump 1 conveys the solution via a pre-filter 2 to a unit 8, in which the mixture to be processed is subjected to a membrane separation process.
- the membrane separation process In the illustrated embodiment, the
- Membrane separation process a microfiltration.
- the microfiltration is carried out in three microfiltration units 8 connected in parallel, which can be loaded alternately.
- the number of microfiltration units 8 can be varied depending on the glycol / water mixture to be prepared.
- Circulation pumps 4 are assigned to the microfiltration units 8, which ensure that the membranes of the microfiltration units 8 are subjected to a pressure of 1 to 6 bar.
- the glycol / water mixture flows at a speed of 1 to 5 m / sec. over the filter surface of the microfiltration unit 8, the filter surface being overflowed in parallel.
- the incoming glycol / water mixture is divided into a stream contaminated with solids, the concentrate 9 and a filtrate stream 10, also called permeate.
- the concentrate stream 9 contains the particles in increased concentration, the filtrate 10 is free of it within the separation limit of the membrane.
- the main stream 9a of the glycol / water mixture is circulated via the
- Microfiltration unit 8 driven. This is shown by the arrow.
- the filtrate 10 and a partial stream of the concentrate 9b are removed from the circuit.
- the feed pump 1 delivers as much glycol / water mixture into the circuit as is removed on the filtrate 10 and concentrate 9b.
- Filtrate 10 is collected in a collecting container 11 in order to be treated in further process steps.
- the partial flow of the concentrate 9b is in one of two concentrate collection containers 12 arranged parallel to one another processed.
- the solids-enriched concentrate 9b is further treated. This results in a further concentration of the solids.
- This second filtration stage consists of two independent units 13, which can be started up alternately. The second filtration stage is fed by feed pumps 14 and works analogously to the first filtration stage. The filtrate 15 obtained in the second filtration stage is also collected via feed lines in the collecting container 11. The main stream of the concentrate 16a is circulated through the microfiltration unit 13. A partial stream of the concentrate 16b is returned to the concentrate collecting container 12. Because of this process control, the solids in the concentrate collecting container 12 are continuously concentrated. If the solids are sufficiently concentrated, the filtration is ended and the mixture is further processed in other steps.
- the entire facility is designed so that individual
- Microfiltration units 8.13 can be cleaned and serviced independently of one another. This ensures a continuous filtration operation even during a maintenance or cleaning process.
- a backflushing device is installed to extend the filtration time. Here, a slightly filtered glycol / water mixture is fed from the filtrate side to the microfiltration units using a backwash pump 17. A short impulse causes the deposits that are formed to be loosened.
- the individual microfiltration units can be rinsed independently of one another.
