Definitions

  • the invention also relates to a compressor module for carrying out the method according to the invention with a two-stage compressor part, a drive part and a power transmission between the compressor part and the drive part via lines with hydraulic fluid.
  • Piston compressors according to the prior art, which compress for example from 1 bar to 300 bar, are built with 3 or 4 stages and driven by a common piston shaft. With a three-stage machine and cooling between the stages, a stage pressure ratio of 6.7 is selected and compressed from 1 bar in the first stage to 6.7 bar in the second stage to 44.9 bar and in the third stage to 300 bar.
  • the inlet pressure can only be varied within very narrow limits. This is disadvantageous if the inlet gas is provided from a pipeline with a pipeline pressure of 7 bar instead of from a gasometer. Another compressor is used, which works with a step pressure ratio of 3.5 bar.
  • the object of the invention is therefore to provide a method and a compressor module for compressing a gas stream, which allow a certain, for example constant, final pressure to be achieved with very different initial pressures of the available gases, the same machines being used in an energetically favorable manner.
  • This object is achieved according to the invention by a method with the features of claim 1 and by a compressor module with the features of claim 6.
  • Embodiments of the invention are the subject of subclaims.
  • the pressure ratios are adjusted in that, with the aid of two adjustable hydraulic oil pumps, a hydraulic oil flow for driving the first compression stage and a hydraulic oil flow for driving the second compression stage are adapted accordingly in terms of their throughput.
  • an inlet pressure changed from 1 bar to 7 bar the hydraulic oil flow for the first stage is reduced and the oil flow for the second stage is increased until both stages are operated at the same pressure ratio, which is the most energetically advantageous when an ideal gas to be compressed is assumed. Because of the deviations of the properties of real gases from the ideal gas and in the case of incomplete recooling to ti, it can make sense to try by changing the
  • the gas stream to be compressed can contain methane or hydrogen or a mixture of methane and hydrogen.
  • the gas stream to be compressed can contain, for example, a natural gas or a methane-containing fraction of a natural gas.
  • a pressure variable between 1 and 10 bar can be used as the inlet pressure pi. In this pressure range, the gas stream to be compressed is almost always made available by pipeline.
  • a fixed pressure between 250 and 350 bar can be used as the outlet pressure p 3 .
  • This is a favorable prerequisite for filling a pressure tank, a pressure gas bottle or a buffer storage.
  • the drive part for each compressor stage contains a hydraulic fluid pump, each with an adjusting device for the delivery rate of the hydraulic fluid. The separate adjustment of the delivery rate makes it possible to set the same pressure ratio or fine-tuned stage pressure ratios in both stages (see above) and exactly the required final pressure of the gas to be compressed at the outlet of the second stage.
  • the compressor stages can each have a liquid-cooled piston compressor and an aftercooler. This enables an almost isothermal compression and a setting of approximately the same inlet temperature in both compressor stages. This leads to a low specific compressor capacity.
  • the aftercooler of the second compressor stage makes it easier to fill a container following the compression, without the container becoming too hot.
  • Each piston compressor ' can have two working cylinders.
  • the pulsations in the pressure-carrying lines are then particularly low.
  • Hydraulic fluid can be applied to the cylinder running surfaces of the working cylinders for cooling from the outside and from the inside. The cooling is then particularly effective.
  • the hydraulic fluid lines can carry at least one air-cooled recooling device for the hydraulic fluid. This is particularly simple in construction and does not represent an additional sound source when operating without a fan, i.e. working with natural convection.
  • the method according to the invention can be used with at least one of the compressor modules according to the invention in a natural gas filling station.
  • a natural gas filling station A nationwide introduction of natural gas filling stations is particularly favored by the fact that with the invention the gas to be compressed, in this case the gaseous fuel for vehicles, can be removed from pipelines operated at different pressures and still be compressed with the aid of piston compressors of the same type and size. It may be necessary that the fuel to be compressed must first be cleaned of particles and dried. After compression, a buffer is useful, from which vehicles can then be filled.
  • the invention is explained in more detail using an embodiment with a figure.
  • the process data mentioned by way of example relate to the use of the invention at a natural gas filling station, that is to say with natural gas as the gas stream to be compressed.
  • the natural gas is taken from a pipeline and processed where necessary for operation in internal combustion engines: for example, particles are removed and the natural gas is dried to less than 10 mol ppm water content. (This treatment is not shown in the figure.)
  • the piston compressor 4 has two working cylinders, the cylinder surfaces of which are cooled with hydraulic oil of approximately 60 ° C.
  • the piston compressor of the second compression stage is driven and cooled in the same way as that in the first compression stage.
  • the pressure medium can be a hydraulic oil, is also used as a coolant and is therefore cooled in the return flow 13, 14 from the piston compressors 4, 6.
  • the compressor module is advantageously constructed in such a way that the drive part and a compression part (with the compressor stages) are each mounted on a base frame and accommodated in a cabinet.
  • Several compressor modules can be used in a natural gas filling station.
