Anton Paar leads the way as the premier solution
provider for both laboratory and inline measurements for the sulfuric acid
industry. Covering the entire sulfuric acid concentration spectrum, from 0
to 100%, and oleum up to 65%, Anton Paar's comprehensive portfolio includes
inline sensors for continuous process monitoring, handheld density meters
for real-time measurements at the production line, as well as the most
accurate density and sound velocity meters for laboratory use.
With more than 40 years of experience in process density measurement and more than 35 years of expertise in inline sound velocity measurement. Our own developed inline density meter L-Dens 7400, the durable and precise inline sound velocity meter L-Sonic 5100 as well as our unique density-sound velocity combined L-Com 5500 concentration meter allow a 24/7 inline monitoring of H2SO4 from 0% to 110%. Due to the genius combination of sound velocity and density, no reversal points for 90% to 110% H2SO4 occur which make it the best possible combination for sulfuric acid and oleum plants. All our sensors are maintenance free, come as a “plug and measure” system and measure with an outstanding accuracy up to ± 0.02 wt%. With wetted parts such as Tantalum, Hastelloy, 24k Gold or Rhodium Anton Paar offers a well proven sulfuric acid concentration determination portfolio for inline and laboratory measurement. With subsidiaries on all continents and our own local sales and service specialists, Anton Paar is the leading expert in liquid analyzing. Our laboratory solutions as well as inline H2SO4 meters are used in sulfuric acid plants all over the world. We can provide references in all major technology packages such as Elessent’s MECS®, DuPont Double Contact Double Absorption technology or Worley’s Chemetics® technology as well as many more. The DSA 5000 lab density and sound velocity meter exemplify efficiency, offering the fastest method to measure sulfuric acid across the entire range without the need for reagents, providing a singular instrument for the entire production process. |

K-Patents
is a global supplier of in-line process refractometers for concentration
measurement of sulfuric acid (H2SO4). The measurement
determines refractive index and temperature and provides temperature
compensated sulfuric acid concentration as % or g/l. We also provide
oleum (SO3 in H2SO4) measurements for
sulfuric acid plants and users. The process refractometer sensors are
factory calibrated and can be used for measurement ranges of 0-85%, 85-100%
sulfuric acid and oleum. |

 |
Inline determination of sulphuric acid and oleum concentrations, measuring
both temperature and sonic velocity inline for precise concentration levels.
With sonic velocity there is not an inflection point between 90-100 %
concentration; and our LiquiSonic® sensors are plug and play, maintenenace
free, without drift or adjustments needed, achieving accuracies of 0.05 %wt
in concentration measurements. |

SICK analyzers and analysis
solutions monitor and check emission limit values, contaminant emissions and
the release of other substances into the environment. Typical applications
are power stations, waste incineration plants, pulp factories, cement
plants, and the chemical industry. Within sulfuric acid plants the analysis of SO2 and O2 at the inlet of the converter as well as SO2, SO3 or H2SO4 at the stack are common applications. |

Acid Mist/SO3
| Company | General Description | Website/e-mail |
| Sigrist-Photometer AG | Scattering of light is by condensed acid mist is usd to measure acid mist content. Sample is cooled to 120°C at which acid mist will condense by water will still be as a vapour. | www.photometer.com/en/abc/abc_098.htm |
| Pentol-Enviro AG | SO3 or H2SO4 is absorbed into a solution of propan-2-ol and reacts with barum chloranilate. Chloranilate ions are measured to determine SO3 concentration | www.pentol.net |
| Ankersmid B.V. |
The SO3 or H2SO4 in the gas sample is
absorbed as sulphate ions (SO42-) in an aqueous
solution of propan-2-ol in water. The solution is passed through a bed of
barium chloranilate. The acid chloranilate ions are measured in a continuous flow photometer. By maintaining a constant ratio of flow rates for the gas and the propan-2-ol absorbing solution, the concentration of acid chloranilate ions can be directly related to the sulphate ion concentration in the absorbing solution, and hence the SO3 concentration in the gas. |
