Definitions
- the invention relates to the compression of CO 2 or nitrous oxide to pressures between 100 and 700 bar with a gas compressor, in particular compressed air operated.
- Piston and diaphragm pumps for pumping liquid CO 2 are also known. These pumps are cooled to prevent a phase transition to the gaseous one. The cooling makes the plant and investment volume relatively expensive.
- the object of the invention is to propose a method for compressing CO 2 or nitrous oxide to high pressures, which can be implemented inexpensively.
- this object is achieved by supplying a gas compressor CO 2 or laughing gas in the liquid state, in particular one operated by compressed air.
- the CO 2 or nitrous oxide should preferably be close to its critical point. It can be in the boiling state with a gas component.
- the temperatures should preferably be between -30 and + 30 ° C.
- the choice of the liquid form of aggregate ensures that a significantly larger amount of CO 2 or nitrous oxide is conveyed and compressed.
- the amount of CO 2 sucked in at the beginning of the compression stroke (the first stage) is decisive for the flow rate, provided the air drive is strong enough. It has now surprisingly been found that the operation with liquid CO 2 works contrary to the predictions of the compressor manufacturers. This is probably due to the fact that the CO 2 is close to its critical point and apparently undergoes a conversion to the supercritical during the first stage lifting process. As a result, the second stage is loaded with a high density, which increases the delivery rate by three times.
- the delivery rate is a commercial, inexpensive gas boosters tripled.
- the specific drive air consumption is halved at least.
- the service life of the gas booster increases same funding volume.
- the area of application of gas boosters becomes significant expanded.
- CO 2 or nitrous oxide can be supplied from bottles, bundles or high-pressure tanks. Operation with a low pressure tank is also possible if the supply line is short and thermally insulated.
- processes which have required bisland high-pressure tanks can now also be operated with CO 2 from a low-pressure tank.
- a low pressure tank is already installed or no high pressure tank is available.
- the invention is particularly suitable for processes in which very high pressures and large amounts of CO 2 are used. This is the case, for example, when foaming plastics.
- a commercial compressed air gas compressor CO 2 can compress to 100 to 700 bar in quantities of 5 to 100 kg / h.
