The invention relates to the field of scale removal for a water system. In order to solve the problems of scale resistance and online scale removal of an MTO water scrubber, the invention provides a scale removing agent used for the MTO water scrubber. The scale removing agent is prepared by putting each component into a container, heating the components until each component is completely dissolved, evenly stirring and mixing to obtain a mixture, cooling the mixture to the room temperature, and obtaining the scale removing agent through filtration. The scale removing agent provided by the invention prevents or reduces the possibility of large particulate matter generation caused by high-condensation-point by-products and catalyst powder, the dissolution of high-condensation-point by-products which form scale is prompted in water at the same time, and the scale in the water scrubber is washed away online.
Description
Technical field
The present invention relates to water system scale removal field, relate in particular to a kind of for MTO water scrubber scale remover.
Background technology
The low-carbon alkene such as ethylene, propylene is the industrial chemicals on the core of petrochemical industry and basis the most, and the especially production capacity of ethylene is to weigh one of mark of a countries and regions chemical industry level.Ethylene currently mainly, production of propylene mode are the cracking techniques with oil as raw material, such as naphtha steam cracking, heavy oil catalytic pyrolysis, ethane cracking etc..Gradually decreasing yet with petroleum resources, uses the challenge that the production line of conventional petroleum raw material is nervous by facing raw material supply.Coal resources relative to petroleum resources relatively horn of plenty, use coal can greatly reduce the consumption of petroleum resources through methanol ethylene, propylene.Methanol-to-olefins (MTO) technique is then to arise at the historic moment in this condition, shows huge potential advantages.
Reaction gas from methanol-to-olefins (MTO) device chilling tower enters water scrubber bottom, and the washing water counter current contacting come with water scrubber top carries out mass-and heat-transfer.The effect of water scrubber mainly has 3；One is by water vapor condensation in reaction gas；Two is to continue to be cooled to compressor inlet temperature by reaction gas, provides low-temperature heat source for separation of olefins unit simultaneously；Three is a small amount of heavy hydrocarbon and oxygenates in elimination reaction.
In MTO course of reaction, in addition to purpose product low-carbon alkene, the by-product such as the most substantial amounts of water vapour, mixed alkanes, aromatic hydrocarbon, coke.In reaction gas enters water scrubber, after heat exchange, temperature reduces, the by-product of high condensation point will separate out, when the high condensation point by-product separated out and catalyst fines coexist in water scrubber, high condensation point by-product plays bridging action and catalyst fines forms large particulate matter, blocks air vent channel, water scrubber tower pressure reduction is caused to raise, affecting the properly functioning of water scrubber, and then affect the normal operation of whole MTO, serious meeting causes the consequences such as whole device shut-down.
At present, it is all to use the catalyst fines in some rotary separators or filter membrane separation water scrubber and the method for high condensation point by-product such issues that of solution.CN203820559U and CN103951098A discloses chilling and washing water in MTO technique and takes off the device of solid oil removing, uses Ultra filtration membrane method to reclaim catalyst fines and high condensation point by-product.All there is limitation in these methods, if high condensation point by-product and acts between catalyst fines forms large particulate matter, and has adhered to and be blocked on tower passage.The most all of segregation apparatus is all helpless.
Up to the present, the report using the method for scale remover to remove the dirty thing formed on MTO washing tower online both at home and abroad is had no.
Summary of the invention
For solving MTO water scrubber anti-tartar and On Line Foul Removing Technology problem, the present invention proposes a kind of for MTO water scrubber scale remover, stop or decrease the possibility of high condensation point by-product and catalyst fines formation large particulate matter, the high condensation point by-product having formed dirt thing can also be promoted to be dissolved in the water, the online dirty thing removed in water scrubber simultaneously.
The present invention is achieved by the following technical solutions: a kind of for MTO water scrubber scale remover, following component is put into vessel in heating and is completely dissolved to each component, is uniformly mixed by scale remover, filters and prepare after being cooled to room temperature, and the weight portion of each component is:
As preferably, the weight portion of each component is:
The preparation method of the water scrubber scale remover of the present invention is simply to heat mixed method, by fatty alcohol-polyoxyethylene ether solubilizing agent, 2-nitro-4-alkylphenol polyoxyethylene solubilizing agent, alkyl phenol polyethenoxy ether sodium sulfate solubilising adjuvant and deionized water, put into vessel in heating to be completely dissolved to each component, it is uniformly mixed, after being cooled to room temperature, it is filtrated to get.Described room temperature is 20～25 DEG C.
Described fatty alcohol-polyoxyethylene ether solubilizing agent structural formula is as shown in (I):
RO(CH2CH2O)nH (I),
Wherein, R=C12～C18Alkyl, the integer between n=15～40, preferably R=C12～C14Alkyl, the integer between n=15～30.
Described 2-nitro-4-alkylphenol polyoxyethylene solubilizing agent molecule formula is as shown in (II):
Wherein, R1=C8～C18Alkyl, the integer between m=15～40, preferably R1=C12～C14Alkyl, the integer between m=15～30.
Described alkyl phenol polyethenoxy ether sodium sulfate solubilising adjuvant molecular formula is as shown in (III):
Wherein, R2=C12～C18Alkyl, the integer between p=3～4, preferably R2=C16～C18Alkyl, the integer between p=3～4.
Detection analysis according to MTO water scrubber tamper is learnt, water scrubber tamper is in addition to the catalyst of vast scale, and also having part is the high condensation point by-product playing bridge formation cementation, such as trimethylbenzene, durol and hexamethylbenzene etc..This scale remover scale removal principle is to select suitable solubilizing agent, increases from dissolubility in water of the high condensation point by-product of reaction gas, and the high condensation point by-product making high condensation point by-product be difficult to separate out or separated out gradually dissolves.Along with the dissolving of high condensation point by-product, stop or decrease and the possibility of catalyst fines formation large particulate matter.The high condensation point by-product having formed dirt thing can also be promoted to be dissolved in the water, the online dirty thing removed in water scrubber simultaneously.Avoiding the non-normal stop caused due to fouling, the long-term operation for MTO device provides essential condition.
The water scrubber scale remover of the present invention is based on solubilizing agent solubilising principle and makes, and the surfactant for solubilising is referred to as solubilizing agent, and the dissolubility increasing indissoluble material forms the process referred to as solubilising of settled solution.Why solubilizing agent can increase the dissolubility of slightly solubility material, is owing to it can form the result of micelle (micelle) in water.Micelle by the lipophilic group of solubilizing agent inwardly (forming a minimum oil droplet, non-polar core district) is, the spheroid that hydrophilic group is outwards formed.Being nonpolar inside whole micelle, outside is polarity.Owing to micelle is small micelle particle.Its dispersion belongs to colloid solution, thus indissoluble material can be made to be contained or adsorb, and increases meltage.Solubilizing agent most suitable hydrophilic-hydrophobic balance value (HLB) is 15-18.
The using method of water scrubber scale remover of the present invention is simple, as long as joining in the washing water of water scrubber.As long as adding concentration more than critical micelle concentration (CMC).
Compared with prior art, the invention has the beneficial effects as follows:
(1) the dirty thing in water scrubber can be effectively suppressed to generate.
(2) can remove the dirty thing generated in water scrubber online, it is to avoid the non-normal stop caused due to fouling, the long-term operation for MTO device provides essential condition.
