Abstract
The invention discloses a new type iron-biting bactericide. The new type iron-biting bactericide comprises tetrakis hydroxymethyl phosphonium sulfate, water, sodium salt of diethylenetriamine penta and sodium hydroxide. The new type iron-biting bactericide disclosed by the invention has the beneficial effects that according to the iron-biting bactericide prepared by the formula and by the mixing effect of the tetrakis hydroxymethyl phosphonium sulfate and the sodium salt of diethylenetriamine penta, the dissolution rate of the ferrous sulfide is increased, and the consumption of the tetrakis hydroxymethyl phosphonium sulfate is reduced, so that the best ferrous-sulfide treating effect is achieved.
Description
(1) technical field
The present invention relates to Iron sulfuret process field, particularly relate to a kind of new-type iron sterilant of biting.
(2) background technology
Current, to locate at oil product storage tank, the oil pipeline etc. of refinery, Iron sulfuret is a kind of very common material.Along with the increase of oil product storage tank duration of service and the effect of corrosive medium, the corrosion protection coating of oil product storage tank inwall there will be local shedding, iron below coating will come out, the main erosion of being corroded rear generation is ferric oxide, ironic hydroxide and Z 250, under the condition that there is no oxygen, may react and transform into Iron sulfuret with the hydrogen sulfide of humidity in storage tank.The Iron sulfuret producing due to corrosion is conventionally on the internals such as storage tank or tower tray, if before maintenance, these inflammable Iron sulfurets do not obtain appropriate processing, are just easy to cause the spontaneous combustion of Iron sulfuret, thereby causes the accident of oil gas blast.Adopt effective agent dissolves to remove the important channel that Iron sulfuret normally solves problems.Processing the sedimental most popular method of Iron sulfuret is at present to dissolve with strong acid.The dissolving meeting corrosion pipeline of strong acid to Iron sulfuret, but also can produce hypertoxic hydrogen sulfide, be therefore badly in need of the Iron sulfuret scale-dissolving agent of exploitation high-efficiency environment friendly.Albright & wilson company of Britain has applied for tetrakis hydroxymetyl phosphonium sulfuric at first for removing the sedimental patent of oil pipe Iron sulfuret.And the tetrakis hydroxymetyl phosphonium sulfuric cleaning Iron sulfuret using on the market is now all that single use tetrakis hydroxymetyl phosphonium sulfuric solution carries out cleaning work mostly, such cleaning effect is lower, and the consumption to tetrakis hydroxymetyl phosphonium sulfuric is larger, can not get best Iron sulfuret cleaning effect.
(3) summary of the invention
The object of the invention is the weak point in order to overcome existing Iron sulfuret process field, and a kind of new-type iron sterilant of biting is provided.
Technical scheme of the present invention is to realize like this.
The new-type iron sterilant of biting of one of this programme, comprise tetrakis hydroxymetyl phosphonium sulfuric, water, diethylene triamine pentamethylene phosphonic sodium and sodium hydroxide, described new-type water that iron sterilant is 50%～60% by mass percent, 30%～40% tetrakis hydroxymetyl phosphonium sulfuric, 4%～8% diethylene triamine pentamethylene phosphonic sodium and 2%～4% the sodium hydroxide bitten mixes.
The water that described new-type mass percent of biting iron sterilant moiety is 55%, 37% tetrakis hydroxymetyl phosphonium sulfuric, 7% diethylene triamine pentamethylene phosphonic sodium and 1% sodium hydroxide.
Described new-type pH value of biting iron sterilant is 4.5～5.5.
Usefulness of the present invention is: according to this recipe configuration out bite iron sterilant, by the mixing effect of tetrakis hydroxymetyl phosphonium sulfuric and diethylene triamine pentamethylene phosphonic sodium, promote the dissolution rate of Iron sulfuret, reduce the consumption of tetrakis hydroxymetyl phosphonium sulfuric, thereby reached best Iron sulfuret treatment effect.
(4) embodiment
Below in conjunction with embodiment, the invention will be further described.
Embodiment: add 550kg water in reactor, then add 370kg tetrakis hydroxymetyl phosphonium sulfuric solid, be stirred to the diethylene triamine pentamethylene phosphonic sodium that adds 70kg after solid fully dissolves, continue to stir, slowly add 10kg sodium hydroxide, by pH regulator to 4.5～5.5.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variation and improvement etc. of doing according to the present patent application scope, within all should still belonging to patent covering scope of the present invention.
Claims (3)
