Description
Technical field
The invention belongs to petrochemical industry, more particularly to a kind of ethane cracking furnace burning process monitoring and control method and dress
It sets.
Background technology
Ethylene is important one of industrial chemicals and demand and the maximum petroleum chemicals of output, more indicates one
The petroleum chemical industry development level of a country.Tube cracking furnace is then the main device for producing ethylene.Hydrocarbon is radiated in pyrolysis furnace
While Duan Fasheng steam cracking reactions, coking can be formed in boiler tube inner wall.Coke thermal resistance is big, while can cause tube fluid
Pressure drop increases.After pyrolysis furnace runs a period of time, radiant section furnace tube wall temperature or quenching boiler is caused to go out due to coking
Mouthful temperature reach capacity or Venturi tube before and after pressure difference when reaching capacity, it is necessary to burning could normal production run.In pyrolysis furnace
In radiant coil burning process, 0 in boiler tube2With vapor under the high temperature conditions with coke gasification reaction, CO is generated2And CO.It is burning
During coke, the air capacity in logical people's boiler tube gradually increases, and steam vapour amount is gradually reduced, CO and C02Content is first improved and is reduced afterwards.
Work as C02When volume fraction is less than 0.2%, indicate that coke has been removed totally in radiant coil, burns end.
The length of pyrolysis furnace charring time, burn efficiency directly affect the yield of ethylene, fuel consumption, the boiler tube service life and
The probability that " temperature runaway " occurs generates significant impact to the production of ethylene.Article《Ethane cracking furnace burns technical progress》Middle introduction
It is various to burn method, but be all that char length is fixed according to preset condition, this method is easy in slight coking excessively to burn
Coke, when severe coking, are easy to burn to be not thorough again, to make next operation lytic cycle shorten.So burning can be monitored in real time
Burnt situation simultaneously carries out the online device that quickly burns of feedback regulation as research hotspot to technological parameter simultaneously.Such as《It is a kind of online
The method for monitoring burn off coke process》《The autocontrol method of online rapid decoking of cracking furnace》《Pyrolysis furnace is quickly burnt online
The exploitation and application of technology》Etc. O by monitoring burning process middle outlet flue gas is had studied in patents and article2、CO2、CO
Content and coil outlet temperature (COT) are come the method that controls intake air and vapor flow and furnace tube temperature.But this method
In be limited to monitoring means and can only monitor coil outlet temperature using thermocouple, and furnace tube temperature it is uneven caused by part temperature
It spends height to detect by peephole by man-hour manually hand-held temperature-measuring gun, this detection mode has very big limitation.And
Patent《A kind of visualization pyrolysis furnace charring state monitoring apparatus》Then use is monitored instead of COT by visualizing infrared temperature measurement apparatus
Visualization infrared temperature measurement apparatus measured temperature while monitoring furnace tube temperature variation in real time, is replaced COT by thermocouple and temperature-measuring gun
Temperature carries out feedback regulation, has certain advance.But visualization infrared temperature measurement apparatus can only survey tube skin temperature, for
The reaction temperature monitoring burnt inside boiler tube is not an extraordinary selection.In addition during adjusting temperature temperature it is equal
Even property and furnace flame situation are also a very important influence factor, and individually visualizing infrared temperature measurement apparatus can not see
The case where fire detecting flame.So this patent is proposed using the field visualized multispectral monitoring device of fire box temperature on the basis of forefathers
In conjunction with coil outlet temperature (COT), burns the composite monitoring device of tail gas many reference amounts gas-monitoring and realized by DCS system real
When feedback regulation, improve the above problem, and by rational closed loop control logic, make to burn control more rationally more scientific.
