Abstract
A deodorizing and passivating cleaning agent for oil refining devices belongs to the technical field of device cleaning agents and is characterized by including (in weight): 20 parts of passivator, 10-14 parts of deodorant, 7-9 parts of active components, wherein the deodorant is compounded by low-alkali sodium hypochlorite, ultrafine sodium silicate and glyoxal diamine, the active components are tetrakis hydroxymethyl phosphonium sulfate (THPS) compound, and the passivator is low-alkali sodium hypochlorite and THPS. Compared with the prior art, the deodorizing and passivating double-effect cleaning agent for the oil refining devices has two functions of deodorizing and passivating, and two effects of deodorizing and passivating can be realized by one-step cleaning process during use of the oil refining devices. Equipment can be cleaned at normal temperature and normal pressure during use, heating is omitted and safety and convenience are achieved.
Description
Technical field
Oil refining apparatus deodorizing passivation economic benefits and social benefits clean-out system belongs to device clean-out system technical field.
Background technology
Refinery is when the refining high-sulpur crude; Sulfide in the crude oil particularly can produce a large amount of Iron sulfurets under the effect at catalyzer in hot conditions, and Iron sulfuret is adsorbed on the equipment and pipeline of refinery; When equipment is opened in shut-down; Iron sulfuret contacts with airborne oxygen and strong redox reaction can take place and emit a large amount of heat, causes spontaneous combustion behind the thermal accumlation, causes fire and explosion hazard.Main organic chelate of ferrous sulfide deactivation cleaning agent commonly used at present and type, acid type, alkalescence, oxygenant (mainly being potassium permanganate, hydrogen peroxide, Youxiaolin, dioxide peroxide); Conventional clean agent function is more single; Can only be to ferrous sulfide deactivation, or can only carry out deodorizing to hydrogen sulfide.
Chinese patent CN 102206830A discloses a kind of neutral cleaners that is used to remove Iron sulfuret and hydrogen sulfide in the oil refining apparatus and preparation method thereof and method of use.The principal character of this invention clean-out system is to be made into by S-WAT, EDTA Disodium, tensio-active agent, poly-epoxy succinic acid ester, water.This clean-out system is a neutral cleaners, and the Iron sulfuret that can effectively remove in the device simultaneously also can the interior hydrogen sulfide of scavenge system.Need cleaning temperature at 50～90 ℃ when this clean-out system uses, need temperature higher, need heat.And to small molecules mercaptan, ammoniacal liquor etc. cause that malodorous compound removal effect is not obvious.
Summary of the invention
The technical problem that the present invention will solve is: overcome the deficiency of prior art, provide a kind of enforcement safe, operation is simple, to various Fouling Cleaning oil refining apparatus deodorizing completely passivation economic benefits and social benefits clean-out system.
The technical solution adopted for the present invention to solve the technical problems is: oil refining apparatus deodorizing passivation economic benefits and social benefits clean-out system; It is characterized in that; By passivator, reodorant and active ingredient are formed by following weight part: 20 parts of passivator, 10～14 parts of reodorant, 7～9 parts of active ingredients; Wherein reodorant is that low alkali value Youxiaolin, ultra-fine water glass and hydroxyethylidene diphosphonic acid compounds are 3: 1: 1 blended mixtures by mass ratio; Active ingredient is a tetra methylol sulfuric acid phosphorus (THPS); Passivator is that low alkali value Youxiaolin and tetra methylol sulfuric acid phosphorus (THPS) are 4: 1 blended mixtures by mass ratio.
The preferred hydroxy ethylene diphosphonic acid of hydroxyethylidene diphosphonic acid compounds (HEDP).
Available chlorine is 8～12% in the said low alkali value Youxiaolin, and alkali concn＜0.4%, POTASSIUM PYROSULPHATE are 2.5～3.5%, and alkaline corrosion inhibitor is 1.8～2.2%.Adopt the Youxiaolin of low alkali value to reduce the pH value of scavenging solution, make the scavenging solution of discharge reach the sewage-farm pH value of intaking and be not more than 9 requirement.
Said ultra-fine water glass preferable particle size is at 0.090～0.106mm.Rest materials is a technical grade.
A kind of preparation method of above-mentioned oil refining apparatus deodorizing passivation economic benefits and social benefits clean-out system is characterized in that: earlier low alkali value Youxiaolin, ultra-fine water glass and hydroxyethylidene diphosphonic acid compounds are mixed at 3: 1: 1 preparation reodorant by mass ratio; Again low alkali value Youxiaolin and tetra methylol sulfuric acid phosphorus are mixed at 4: 1 preparation passivator by mass ratio; By weight 20 parts of reodorant, 10～14 parts of passivator and 7～9 parts of active ingredients are mixed, continuously stirring evenly promptly gets.
The method of use of above-mentioned oil refining apparatus deodorizing passivation economic benefits and social benefits clean-out system is characterized in that: during use, according to the oil refining apparatus internal surface area, by 10～25kg/m
2Usage quantity preparation economic benefits and social benefits clean-out system, inject oil refining apparatus behind 10～50 times of the dilute with waters, soak and detect behind the circulation 6h continuously, detection reaction fully after, continue wash cycles 60～120min again, discharge.
The main component of deodorizing passivation economic benefits and social benefits clean-out system of the present invention all is alkalescence, and compound property is good, stable in properties.Passivator has passivation to Iron sulfuret.Reodorant causes that to hydrogen sulfide, small molecules mercaptan, ammoniacal liquor etc. malodorous compound has absorption, oxidation, removes function of odor.Active ingredient has the dispersion compatibilization.Wherein low alkali value chlorine bleach liquor and weakly acidic hydrogen sulfide, small molecules mercaptan neutralize, oxidizing reaction.Ammoniacal liquor absorbed by sodium silicate solution and with second two hangover diamine compound reaction conversions be that nitrogen is overflowed; Iron sulfuret is converted into ferric sulfate, red stone by low alkali value Youxiaolin, tetra methylol sulfuric acid phosphorus (THPS), and it is dangerous to eliminate spontaneous combustion.
Compared with prior art; The beneficial effect that oil refining apparatus deodorizing passivation economic benefits and social benefits clean-out system of the present invention is had is: because oil refining apparatus deodorizing passivation economic benefits and social benefits clean-out system of the present invention has deodorizing and two kinds of functions of passivation; Oil refining apparatus can be realized deodorizing, two kinds of effects in two steps of passivation through a step cleaning during use; Effectively the environmental problem that causes such as removal of hydrogen sulfide, small molecules mercaptan, ammoniacal liquor solves equipment and member thereof simultaneously because of the hidden danger that the Iron sulfuret spontaneous combustion brings for safety inspection and equipment takes place.Under the normal temperature and pressure equipment is cleaned during use, need not heating, safe ready.
