Definitions
- the present invention relates to a method for handling aqueous solutions of methanesulfonic acid in austenitic steel devices having a chromium content of 15 to 22 wt.% And a nickel content of 9 to 15 wt.%.
- Methanesulfonic acid (H3CSO3H, MSA) is a strong organic acid used in a variety of different processes, including galvanic processes, chemical synthesis, detergents, and tertiary mineral oil production.
- MSA can be produced by various processes, for example by
- Chlorine compounds such as chloride contains.
- WO 00/31027 discloses a method of oxidizing dimethyl disulfide with nitric acid to MSA, wherein the nitrogen oxides formed are reacted with O 2 again to nitric acid and this is returned to the process.
- CN 1 810 780 A discloses a process in which ammonium sulfite and / or ammonium bisulfite with dimethyl sulfate to
- Ammonium methanesulfonate and ammonium sulfate is reacted.
- the ammonium sulfate can be precipitated with Ca 2+ as CaSC.
- MSA can be released with sulfuric acid and worked up, again precipitating CaSC.
- EP 906 904 A2 discloses a process in which sodium sulfite is reacted with dimethyl sulfate. From the resulting mixture MSA can be released after acidification with concentrated sulfuric acid. The last three mentioned methods have the advantage that the resulting MSA is virtually free of chlorine compounds.
- the object of the invention was therefore to find cheaper, lower alloyed steels for the production of such building parts, which still have a good corrosion resistance to aqueous MSA solutions.
- a method of handling aqueous solutions of methanesulfonic acid (MSA) having a concentration of 50 to 99 wt.% MSA and a total chlorine content of less than 50 mg / kg in apparatuses wherein the aqueous MSA solution has steel surfaces in Contact is found, wherein the steel is austenitic steels having a chromium content of 15 to 22 wt.% And a nickel content of 9 to 15 wt.%.
- the process of the present invention relates to handling of aqueous solutions of methanesulfonic acid (H3CSO3H, MSA) in devices in which the aqueous MSA solution is in contact with steel surfaces.
- the aqueous MSA solutions in this case have a concentration of 50 to 99 wt.% MSA with respect to the sum of all components of the aqueous solution.
- the concentration is preferably 55 to 90% by weight, more preferably 60 to 80% by weight and most preferably about 70% by weight.
- the aqueous MSA solutions may contain, in addition to water and MSA, customary secondary constituents and / or impurities.
- the total content of chlorine in the aqueous MSA solution is less than 50 mg / kg, preferably less than 25 mg / kg and most preferably less than 10 mg / kg.
- the chlorine may, for example, be chlorine in the form of chloride ions or chlorine bound in organic compounds.
- MSA solutions having such a low total chlorine content can be prepared according to methods known to those skilled in the art, for example by oxidation of dimethyl disulfide using nitric acid by the method disclosed by WO 00/31027, or from ammonium sulfite and / or ammonium hydrogen sulfite by reaction with
- the aqueous MSA solution may also contain sulfate ions as an impurity.
- the amount of sulfate ions should, however, generally be less than 300 mg / kg, preferably less than 200 mg / kg, more preferably less than 100 mg / kg and in particular less than 30 mg / kg.
- Transport or use of MSA solutions It is preferably the storage and / or transport of aqueous MSA solutions.
- the devices may be any type of device used in the handling of aqueous MSA solutions, provided they have steel surfaces that can be contacted by the aqueous MSA solutions.
- the devices may be composed of such steels in their entirety, but may of course include other materials. For example, it may be devices made of a different material or a different steel, which are lined with the steel according to the invention.
- the devices may be closed or open devices, for example devices selected from the group of tanks, storage containers, rail tank cars, tanker trucks, tank containers,
- Reaction boilers dosing devices, pipelines, flanges, pumps or measuring and control components, trays, drums, devices for galvanizing, components of boilers such as flow breakers, stirrers or metering tubes act.
- the steel surfaces which are in contact with the aqueous MSA solution are surfaces of austenitic steels with a
- austenitic steel is known to the person skilled in the art, for example from “Römpp Online, Version 3.5, Georg Thieme Verlag 2009".
- the preferred chromium content is 16 to 20 wt.%, The preferred Ni content 10 to 14 wt.%.
- the steel also comprises manganese, in an amount of 1 to 3 wt.%.
- the steels used according to the invention may contain 1 to 5% by weight of molybdenum, preferably 1 to 5 to 4, particularly preferably 2 to 3% by weight.
- the steels may contain 0.1 to 2 wt.% Titanium, preferably 0.5 to 1 wt.%.
- these may be steels which comprise the elements indicated below (in each case in% by weight):
- Contact is usually less than 40 ° C, without the invention should be limited to this temperature.
- the temperature is 10 to 40 °, preferably 15 to 30 ° C and for example about ambient temperature.
- test duration was 7 days, the temperature 23 ° C. For steel No. 4, the test duration was 1 day.
- Corrosion rate [mm / a] 87600 * ⁇ m / A * p * t, where ⁇ m is the mass change of the sheet [g], A is the area of the sheet [cm 2 ], p is the density of the steel [g / cm 3 ] and t represents the duration of the experiment [h].
- the factor 87600 is used to convert from cm / h to mm / a. The results are shown in Figures 1 and 2.
- Figure 1 shows the corrosion rates (CR) in mm / year for steels # 1 ( Figure 1 a), 2 ( Figure 1 b), and 3 ( Figure 1 c).
- the experiments show that only with the Methansulfonsauren, which have a low content of total chlorine in all experiments low corrosion rates are achieved.
- MSA3 shows with the steel no. 1 and 3 are passable results, but not with steel no. 2.
- the corrosion rate is about 0.01 mm / a, and when using steels no. 2 and 3, well below 0.01 mm / a.
- Figure 2 shows corrosion rates (CR) in mm / year for not
