Abstract
The invention discloses a kind of novel MTO water scrubber dispersing agents, include following component according to weight percent: 10~20% nonylphenol polyoxyethylene ether, 3~8% methylene how sodium sulfonate, 3~10% sodium lignin sulfonates, surplus is water.The present invention is compared with prior art, the dispersion effect of dispersing agent is significantly enhanced, it can be good at dispersing the wax formed in MTO water scrubber, good cleaning effect can be kept under the hot environment in MTO water scrubber additionally, due to dispersing agent, it can be by the wax and other impurities by dispersion, dirt is cleaned, it is coalesced to prevent wax and catalyst fines to be blended at the turning and dead angle of tower tray, not only extend water scrubber uses the time, improve process efficiency, and tower pressure difference not will rise, improve production capacity and economic benefit.
Description
Technical field
The invention belongs to technical field of chemical products, and in particular to a kind of novel MTO water scrubber dispersing agent and its preparation
Method.
Background technique
The main task of the water scrubber of MTO (methanol-to-olefins device) is a small amount of catalyst carried secretly in washing reactor,
Moisture in condensation reaction gas, the washing water for cleaning product gas is to be recycled, since cyclone hydraulic separators cannot will wash
The fully effective separation of catalyst fines in water excludes, while generating in MTO reaction gas containing a small amount of more toluene, formed with
Durol, pentamethylbenzene, the miscella wax based on hexamethylbenzene, the miscella wax and catalyst fines are blended in tower tray
It is coalesced at turning and dead angle, the pressure difference of tower is caused to become larger, will form shut-down cleaning when serious.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, provide a kind of novel MTO water scrubber dispersing agent and
Preparation method, the dispersing agent can carry out effective dispersion and peace and quiet to the wax that is formed in MTO water scrubber, prevent tower
Blocking.
Technical solution: to achieve the above object, the present invention provides a kind of novel MTO water scrubber dispersing agent, according to weight
Percentage includes following component:
10~20% nonylphenol polyoxyethylene ether, 3~8% methylene how sodium sulfonate, 3~10% sodium lignin sulfonates are remaining
Amount is water.
Further, include following component according to weight percent:
13~17% nonylphenol polyoxyethylene ether, 4~6% methylene how sodium sulfonate, 4~7% sodium lignin sulfonates, surplus
For water.
Further, include following component according to weight percent:
15% nonylphenol polyoxyethylene ether, 5% methylene how sodium sulfonate, 5% sodium lignin sulfonate, 80% water.
A kind of preparation method of novel MTO water scrubber dispersing agent, detailed process are as follows: water is added in a kettle, so
Sequentially add according to the ratio afterwards nonylphenol polyoxyethylene ether, methylene how sodium sulfonate and sodium lignin sulfonate, stir evenly sufficiently mixed
It closes, blowing packaging.
Further, the time of the stirring is 30~50 minutes.
Nonylphenol polyoxyethylene ether is a kind of nonionic surfactant in the present invention, and cloud point is higher, in the height of water scrubber
Still with good cleaning effect under temperature (cloud point of anion and cation is relatively low).
Methylene how sodium sulfonate and sodium lignin sulfonate, have good collaboration dispersion effect, enable miscella wax object
It is good to be dispersed.
The innovation of the invention consists in that: nonylphenol polyoxyethylene ether can with methylene how sodium sulfonate and sodium lignin sulfonate
Cleaning function under hot environment that nonylphenol polyoxyethylene ether has perfectly is offered to final molding by the compatible matching of perfection
Dispersing agent solves existing MTO water scrubber dispersing agent because high temperature limits, can not have the problem of cleaning function；In addition, sub-
Methyl how both sodium sulfonate and sodium lignin sulfonate structural formula and characteristic can perfect matching, play the effect mutually promoted,
Have collaboration dispersion effect, breaches the functional limitation of existing dispersing agent.
The utility model has the advantages that compared with prior art, the present invention the dispersion effect of dispersing agent is significantly enhanced, it can be fine
The wax formed in MTO water scrubber is dispersed, can be in the hot environment in MTO water scrubber additionally, due to dispersing agent
It is lower to keep good cleaning effect, the wax for passing through dispersion and other impurities, dirt can be cleaned, to prevent
Wax and catalyst fines are blended at the turning and dead angle of tower tray and coalesce, and not only extend water scrubber uses the time,
Process efficiency is improved, and tower pressure difference not will rise, improves production capacity and economic benefit.
Specific embodiment
Combined with specific embodiments below, the present invention is furture elucidated.
Embodiment 1:
A kind of novel MTO water scrubber dispersant A, includes following component according to weight percent:
10% nonylphenol polyoxyethylene ether, 3% methylene how sodium sulfonate, 3% sodium lignin sulfonate, 84% water.
A kind of preparation method of novel MTO water scrubber dispersing agent, detailed process are as follows: be added match in a kettle
Water, then sequentially add according to the ratio nonylphenol polyoxyethylene ether, methylene how sodium sulfonate and sodium lignin sulfonate, stir 30 points
Clock is sufficiently mixed, blowing packaging.
Embodiment 2:
A kind of novel MTO water scrubber dispersant B, includes following component according to weight percent:
20% nonylphenol polyoxyethylene ether, 8% methylene how sodium sulfonate, 10% sodium lignin sulfonate, 62% water.
A kind of preparation method of novel MTO water scrubber dispersing agent, detailed process are as follows: be added match in a kettle
Water, then sequentially add according to the ratio nonylphenol polyoxyethylene ether, methylene how sodium sulfonate and sodium lignin sulfonate, stir 50 points
Clock is sufficiently mixed, blowing packaging.
Embodiment 3:
A kind of novel MTO water scrubber dispersing agent C, includes following component according to weight percent:
15% nonylphenol polyoxyethylene ether, 5% methylene how sodium sulfonate, 5% sodium lignin sulfonate, 80% water.
A kind of preparation method of novel MTO water scrubber dispersing agent, detailed process are as follows: be added match in a kettle
Water, then sequentially add according to the ratio nonylphenol polyoxyethylene ether, methylene how sodium sulfonate and sodium lignin sulfonate, stir 40 points
Clock is sufficiently mixed, blowing packaging.
Embodiment 4:
Dispersant A, dispersant B and the dispersing agent C and existing of Examples 1 to 3 acquisition are utilized respectively in the present embodiment
Dispersing agent D is separately in the same MTO water scrubber, under identical process environments and raw material condition, in dispersant A, is divided
Under the use of powder B and dispersing agent C, the miscella wax generated in MTO water scrubber will not occur to assemble situation, these miscella waxes
Water scrubber can be discharged in the overwhelming majority with waste water after dispersion, and in entire technical process, the tower pressure of MTO water scrubber is always
It keeps stablizing, obviously not rise；Under the use of dispersing agent D, as miscella wax gradually increases in MTO water scrubber, this
A little miscella waxes and catalyst fines and some other impurity can accumulate in one piece, and be flocked on the turning and dead angle of tower tray
Locate, in entire technical process, the tower pressure of MTO water scrubber in trend is gradually increasing, (namely wash by the final technological reaction time
The time used of tower) than dispersant A, dispersant B and dispersing agent C use when extend 30%, whole energy consumption is wanted
When being apparently higher than dispersant A, dispersant B and dispersing agent C use.
It is very good using the clean condition in the MTO water scrubber of dispersant A, dispersant B and dispersing agent C after technique,
It can continue to come into operation substantially without cleaning is carried out；It is very bad using clean condition in the MTO water scrubber of dispersing agent D,
There are a large amount of oily wax, dirt and impurity etc. to be also located in water scrubber, after staff has to pass through long period cleaning, MTO water
Washing tower could continue to come into operation.
