Acid sampling system

for the pharmaceutical industrystainless steel

At Biar Inc., we design and manufacture valves for pure or concentrated aqueous hydrofluoric acid sampling applications. Hydrofluoric acid is used in the production of numerous products such as pharmaceutical compounds, as well as in hydrofluoric acid alkylation units that are found in the petrochemical refining industry. With such widespread use, especially in applications within the pharmaceutical industry, precise sampling of hydrofluoric acid streams is imperative. However, hydrofluoric acid is an extremely dangerous chemical and is known to destroy skin, subdermal tissue, and bone, as well as damage eyes to the point of vision loss, on contact. Deaths have been reported as a direct result of acid burns that involved as little as 2.5% of the body surface area. Obviously, when sampling a chemical this lethal, no exposure to the outside environment or operator is to be allowed. To overcome these challenges, a material with a strong resistance to acids must be selected. For some alkylation solution sampling applications, 316L stainless steel can be used, but for higher acid concentrations, specialty HSLA alloys such as Monel 400, Alloy20, or Hastelloy are typically chosen. The exact material of construction (MOC) is ultimately chosen by the customer based on the nature of their processing stream. For hydrofluoric acid sampling, we recommend a multi-function metallic valve with a bellows type seal, stuffing box and leak detection port. Multi-function valves are designed for the easy removal and cleaning of the adapter, allowing the customer to clean the valve after every sampling procedure, without the use of.
