Abstract
The invention discloses a kind of method of purification of methane, including 0.1Pa will be evacuated to inside condensing container；As injection needs the methane gas purified inside condensing container；Condensing container is cooled to 50 degree or so, and keeping temperature stands 10min；Condensing container upper gas is exported into filter, then the gas of the solidifiable such as the carbon dioxide that bottom in condensing container is solidified is excluded；The gas filtered in filter is injected in container, you can the methane gas purified.Compared with prior art, the present invention is main is purified by way of condensing and filtering, and without adding other chemosorbents etc., is saved cost, is simplified processing technology, operating efficiency is improved, with the value promoted the use of.
Description
Technical field
The present invention relates to a kind of gas purifying method, more particularly to a kind of method of purification of methane.
Background technology
Methane is very wide in the distribution of nature, and methane is simplest organic matter, is natural gas, and biogas cheats the master of gas etc.
Composition is wanted, gas is commonly called as.It is also that phosphorus content is minimum（Hydrogen content is maximum）Hydrocarbon, be also natural gas, biogas, casing-head gas and coal mine
The main component of road gas.It can be used as the thing such as fuel and manufacture hydrogen, carbon black, carbon monoxide, acetylene, hydrogen cyanide and formaldehyde
The raw material of matter.In the prior art, the purity of methane is not mostly high, so as to cause efficiency of combustion not high, especially the first in biogas
Alkane, containing substantial amounts of carbon dioxide, reduces efficiency of combustion, accordingly, it would be desirable to be purified to it.
The content of the invention
The purpose of the present invention is that provides a kind of method of purification of methane to solve the above problems.
The present invention is achieved through the following technical solutions above-mentioned purpose：
The present invention comprises the following steps：
（1）0.1Pa will be evacuated to inside condensing container；
（2）As injection needs the methane gas purified inside condensing container；
（3）Condensing container is cooled to -50 degree left and right, and keeping temperature stands 10min；
（4）Condensing container upper gas is exported into filter, then the carbon dioxide that bottom in condensing container is solidified etc.
The gas of solidifiable is excluded；
（5）The gas filtered in filter is injected in container, you can the methane gas purified.
Specifically, the step（3）In filter filtering size be 1000 mesh.
As an improvement, purification after methane gas in, injection 20% oxygen mix, obtain the methane gas of efficient burning.
The beneficial effects of the present invention are：
The present invention is a kind of method of purification of methane, compared with prior art, and the present invention is main by way of condensing and filtering
Purified, without adding other chemosorbents etc., save cost, simplify processing technology, improved operating efficiency, have
The value promoted the use of.
Embodiment
The invention will be further described below：
The present invention comprises the following steps：
（1）0.1Pa will be evacuated to inside condensing container；
（2）As injection needs the methane gas purified inside condensing container；
（3）Condensing container is cooled to -50 degree left and right, and keeping temperature stands 10min；
（4）Condensing container upper gas is exported into filter, then the carbon dioxide that bottom in condensing container is solidified etc.
The gas of solidifiable is excluded；
（5）The gas filtered in filter is injected in container, you can the methane gas purified.
Specifically, the step（3）In filter filtering size be 1000 mesh.
As an improvement, purification after methane gas in, injection 20% oxygen mix, obtain the methane gas of efficient burning.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
