Definitions
- the invention relates to a method for compressing a gas stream of the inlet temperature t 1 with the aid of hydraulically driven piston compressors in two compression stages from an inlet pressure p 1 to an intermediate pressure p 2 after the first compression stage and from the intermediate pressure p 2 to an outlet pressure p 3 after the second compression stage ,
- the invention also relates to a compressor module for performing the inventive method 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.
- a generic method for compressing a gas stream is for example known from US-A-5 863 186.
- Piston compressors for example from 1 bar Compress 300 bar, are built with 3 or 4 stages and over a common Piston shaft driven. With a three-stage machine and cooling between the In stages, a stage pressure ratio of 6.7 is selected and 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 compacted.
- the inlet pressure can only be varied within very narrow limits. This is disadvantageous if the entry gas instead of a gasometer from a pipeline with 7 bar pipeline pressure. Another compressor will 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 To show compression of a gas stream, which is very different Initial pressure of the available gases a certain constant, for example Allow to achieve final pressure, the same machines being energetically favorable be used.
- the pressure ratios are adjusted by adjusting a hydraulic oil flow for driving the first compression stage and a hydraulic oil flow for driving the second compression stage with the aid of two adjustable hydraulic oil pumps.
- 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.
- the deviations of the properties of real gases from the ideal gas and in the case of incomplete recooling to t 1 it can make sense to seek out an operation that is even more energy-efficient in a trial manner by changing the pressure ratios of the stages to one another with almost the same pressure ratio.
- this re-optimization is familiar to the person skilled in the art, it can be carried out particularly easily with the aid of the drive according to the invention.
- the one to be compressed can Gas flow methane or hydrogen or a mixture of methane and hydrogen contain.
- the gas stream to be compressed can be, for example, a natural gas or a contain methane-containing fraction of a natural gas.
- a pressure variable between 1 and 10 bar can be used as the inlet pressure p 1 .
- the gas flow 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 a hydraulic fluid pump with one each Includes adjustment device for the flow rate of the hydraulic fluid.
- the Compressor stages via one liquid-cooled piston compressor and one each Aftercoolers. This creates an almost isothermal compression and a Setting of approximately the same inlet temperature in both compressor stages allows. This leads to a low specific compressor capacity.
- the Aftercooler of the second compressor stage makes it easier to fill one of the Compression of the following container without it overheating.
- Each piston compressor can have two working cylinders.
- the pulsations in the pressure-carrying lines are then particularly low.
- Cylinder running surfaces of the working cylinders can be used for cooling from the outside and from the inside be charged with hydraulic fluid. The cooling is then particularly effective.
- the hydraulic fluid lines can be at least one air-cooled Guide the recooling device for the hydraulic fluid.
- Such is special simple in construction and provides for operation without a fan, i.e. with natural Working convection, no additional sound source.
- the method according to the invention can be carried out with at least one of the inventive methods
- Compressor modules can be used in a natural gas filling station.
- the fuel may be compressed to contain particles beforehand must be cleaned and dried. After compression, there is a buffer useful, from which vehicles can then be refueled.
- 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, ie with natural gas as a 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 a water content of less than 10 mol-ppm. (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 in 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 so that the drive part and a Compression part (with the compressor stages) mounted on a base frame and are housed in a cupboard. There can be several in a natural gas filling station Compressor modules are used.
