Description
Technical field
The present invention relates to the carbon monoxide transformation technical in Coal Chemical Industry production, be specifically related to the isothermal conversion technical method of carbon monoxide.
Background technology
Crushed coal pressure gasifying technique is the conventional process during Coal Chemical Industry is produced, and the principal feature of this gasifying process is that gasification temperature is lower, the methane component that contains 8-12% in institute's producing coal gas.In coal gas processing treatment hydrogen making process, this part methane component out (is wherein contained a small amount of carbon monoxide) at liquid nitrogen wash process by low temperature separation process, is sent to steam methane conversion/changing device and recycles.
In order to prevent in methane fraction process gas that contained carbon monoxide disproportionation reaction occurs when entering steam methane reformer tube and causes and analyse carbon, need to first to process gas, carry out carbon monoxide converts in advance, after carbon monoxide content in process gas is significantly reduced, then enter steam methane conversion procedure.In actual production, carbon monoxide content in methane fraction process gas is very unstable, often exceed design load, cause and in carbon monodixe conversion stove, produce too much reaction heat, cause shift converter overtemperature, break through catalyst heat-resistant limit, cause the transformation catalyst activity even inactivation that declines, production cannot normally be carried out.
Summary of the invention
Object of the present invention overcomes the above problems exactly, and a kind of carbon monoxide isothermal conversion technical method is provided, and makes carbon monodixe conversion stove in carbon monoxide transformation process, keep constant temperature, guarantees normally carrying out of conversion process.
The present invention is achieved by the following technical solutions:
Carbon monodixe conversion stove adopts shell and tube isothermal shift converter, tube side filling Cu-series catalyst, and shell side is the water bath with thermostatic control that adds oiler feed; At carbon monodixe conversion furnace roof, portion establishes steam drum, is connected with shell side water bath with thermostatic control.
Methane fraction process gas is passed through from the tube side of carbon monodixe conversion stove, and carbon monodixe conversion reaction occurs under catalyst action, then leaves carbon monodixe conversion stove; Reaction heat reaches shell side by tubulation tube wall, heating boiler feedwater, and by-product low-pressure steam.
The design of above technical process, has guaranteed the temperature-stable of tube side inner catalyst, thereby while having guaranteed that in methane fraction process gas, carbon monoxide content fluctuates, normally carrying out of transformationreation, has also guaranteed the safety of changing device.
Carbon monoxide isothermal conversion technical method of the present invention efficiently solves because carbon monodixe conversion stove entrance carbon monoxide concentration is high, causes the high even problem of inactivation of catalyst activity reduction that causes of reaction bed temperature, and process conditions elasticity increases.
Accompanying drawing explanation
Fig. 1 is the process flow sheet of carbon monoxide isothermal conversion technical method of the present invention.
Embodiment
300,000 tons/year of coal synthesis ammonia devices of certain group increase production in 50% energy saving technical reconstruction, in order to prevent methane fraction process gas, in steam methane reformer tube ingress, analyse carbon, original design process gas is introduced into the pre-shift converter of adiabatic low temperature, the carbon monoxide content in process gas is down to below 1% by 13.5%.
In device operation operational process, due to the needs of liquid nitrogen washing device cold balancing, in isolated methane fraction, carbon monoxide content is very unstable, often surpasses 15%.When this strand of gas enters the pre-shift converter participation of the adiabatic low temperature carbon monodixe conversion reaction before steam methane conversion/changing device, often cause the pre-shift converter overtemperature of adiabatic low temperature, cause the transformation catalyst activity even inactivation that declines, have a strong impact on the safe and stable operation of whole device.
For this reason, the present invention creatively changes adiabatic low temperature shift converter into shell and tube isothermal shift converter 1, shift converter tube side filling Cu-series catalyst is walked methane fraction process gas, and shell side is that water bath with thermostatic control adds oiler feed, is continuously removed the reaction heat that in tube side, process gas conversion produces.At shift converter 1 top, establish steam drum 2, be connected with by-product low-pressure steam with shell side water bath with thermostatic control.Fig. 1 has marked major equipment that this processing method comprises and the trend of processing medium.
Above-mentioned processing method has solved the difficult problem that former adiabatic low temperature shifting process easily causes shift converter overtemperature, has guaranteed normally carrying out of transformationreation, thereby has guaranteed the normal production of whole steam methane conversion/changing device.
