Embodiment Construction
[0028] In view of many deficiencies in the prior art, the inventor of this case has been able to propose the technical solution of the present invention after long-term research and extensive practice, which will be specifically explained as follows.
[0029] One aspect of the embodiments of the present invention provides a high gravity desulfurization method based on a sacrificial (also called "disposable") desulfurizer, which includes:
[0030] Remove most of the dust particles entrained in the raw material gas to realize the dust removal treatment of the raw material gas;
[0031] Inputting the raw material gas treated by dedusting into the desulfurization pre-sprayer, making the raw material gas spray and contact with the desulfurizing agent in the desulfurization pre-sprayer, so as to realize the preliminary removal of sulfur-containing gas in the raw material gas;
[0032] The raw material gas that has been preliminarily desulfurized is input into the supergravity reacto...

The invention discloses a super-gravity desulfurization method based on a sacrificial desulfurizer. The method comprises removing dust in raw material gas, feeding the raw material gas subjected to dust removal into a desulfurization pre-sprayer, preliminarily removing sulfur-containing gas in the raw material gas, feeding the raw material gas subjected to preliminary desulfurization into a high gravity reactor, deep removing the sulfur-containing harmful gas in the raw material gas to obtain purified raw material gas, removing desulfurization agent droplets in the purified raw material gas, outputting the raw material gas, wherein the desulfurization agent at least circulates among the desulfurization pre-sprayer, the gravity reactor and a desulfurization agent storage tank, discharging the disabled desulfurization agent and feeding a fresh desulfurization agent. The invention also discloses a super-gravity desulfurization packaged device. The super-gravity desulfurization method realizes the efficient removal of dust and hydrogen sulfide under field conditions, has low energy consumption and is free of desulfurization agent regeneration. The super-gravity desulfurization packageddevice has a small occupied area and low energy consumption, realizes automatic control and operation and can work for a long time.
Description
technical field [0001] The present invention relates to a desulfurization method and a desulfurization device, in particular to a sacrificial desulfurizer-based supergravity desulfurization method and a prying device, which are suitable for coalbed methane, shale gas, oilfield associated gas, offshore oil production associated gas, etc. Purification and removal of hydrogen sulfide in natural gas. Background technique [0002] Produced natural gas, including oilfield associated gas, coal bed methane, and shale gas, often contains acidic gases such as hydrogen sulfide. These acidic gases and water vapor are highly corrosive and pose a great threat to pipelines. , In addition, hydrogen sulfide is a highly toxic gas, so mandatory national standards require that natural gas must be purified. [0003] The desulfurization process can be divided into two categories: solid desulfurization method and liquid desulfurization method according to the different desulfurizers used: [000...
