Description
Technical field
The method that the present invention relates to a kind of tail gas recycling, especially relates to one and utilizes hydrogen to divide with carbon monoxide
The method doing reburner fuel from ice chest tail gas.
Background technology
The process of industrial tail gas is usually and carries out adsorbing and processing according to its physics, chemical property, at very great Cheng
The waste liquid after putting into manpower and materials, and process and the recovery of waste residue is needed on degree.As sulfuric acid industry tail gas needs ammonia
Water adsorbs, nitric acid industry tail gas needs to adsorb etc. with sodium hydroxide.Although this processing mode can reduce
The tail gas pollution to environment, but relatively low to the utility utilization rate in tail gas.
HyCO i.e. hydrogen and the mixture (Hydrogen+CO) of carbon monoxide.The HyCO of narrow sense is to produce simultaneously
Hydrogen and the chemical process of carbon monoxide.Owing to carbon monoxide the most all produces with hydrogen simultaneously, because of
This in gas industry people with HyCO represent major product be hydrogen and/or carbon monoxide and/or hydrogen, one
The chemical production device of carbon oxide mixture (synthesis gas, or Syngas) or production technology.
The production technology of HyCO includes producing synthesis gas (Generation) and synthesis gas isolated or purified
(Separation or Purification) two stages.Purification phase main method include sour gas removing (AGR,
Acid Gas Removal), membrance separation (Membrane), ice chest (Coldbox), pressure-variable adsorption (PSA).
HyCO ice chest technique is particularly as follows: synthesis gas is through being stripped of H2O、CO2、H2After the impurity such as S, through deep cooling
Hydrogen is separated with carbon monoxide by technical cooling to about-180 DEG C, thus obtains pure carbon monoxide product.
HyCO ice chest is synthesis gas isolation of purified CO and H2, mainly by raw material containing 54%CO and 45%H2
And the N of trace2、CH4, the gas such as Ar boiling point different by CO and H2The purifying plant separated, cold
The tail gas of case is mainly composed of the N of trace2、CO、H2, Ar and the rare gas of other components.The most right
The processing method of ice chest tail gas is for putting to torch burning.This mode causes the waste of tail gas, lacks tail gas warp
The recycling that Ji is worth.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and provide a kind of cost-effective,
Economic worth is big, the hydrogen that utilizes of environment-protecting clean separates the method that ice chest tail gas does reburner fuel with carbon monoxide.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of hydrogen is utilized to separate the method that ice chest tail gas does reburner fuel with carbon monoxide, by a part of ice chest tail
Gas is connected to torch burning by discharge tube, is connected to convert by tail gas recycling pipeline by residue ice chest tail gas
Stove, as reburner fuel；Described discharge tube be provided with regulation enter torch burning ice chest exhaust flow with
The regulation valve of pressure, described tail gas recycling pipeline is provided with regulation and enters the ice chest exhaust flow of reburner burning
Regulation valve with pressure.
The method specifically includes following steps:
(1) reburner is opened so that it is normal production run；
(2) the regulation valve on regulation discharge tube, makes the pressure of the ice chest tail gas of entrance torch burning be adjusted to
0.6～1bar；
(3) the regulation valve on regulation tail gas recycling pipeline, makes the pressure of the ice chest tail gas that entrance reburner burns
It is adjusted to 0.4～0.8bar；
(4) flow controlling to enter the ice chest tail gas of reburner burning is 30～120m3/h。
Described reburner is the reburner carrying out methane steam reforming (SMR).
As preferably, regulate the regulation valve on discharge tube, make the pressure regulation of the ice chest tail gas of entrance torch burning
For 0.8bar；Regulation valve on regulation tail gas recycling pipeline, makes the pressure of the ice chest tail gas that entrance reburner burns
It is adjusted to 0.7bar；The flow controlling to enter the ice chest tail gas of reburner burning is 90m3/h。
Compared with prior art, the invention have the advantages that
(1) this method does not has poisonous gas due to tail gas content, may be used for any dress fuel being had to demand
Put.
(2) fuel saving natural gas that this method is covert, creates economic worth.
(3) this method decreases CO for environment2Discharge, has the biggest environmental protection.
(4) this method is owing to tail gas pressure is less than 1barg, so this root pipeline safety, will not convert SMR
Impacting of the pressure of stove fuel system.
