Applications

Oleum

The Dynatrol® CL10-HY Density Cell and Series 2000 Density Digital Converter can be used to measure oleum (fuming sulfuric acid).

The oleum application software is designed to use the temperature and density information that comes from the CL-10HY cell to calculate product density at a reference temperature, specific gravity and percent free SO3 concentration or the output can be expressed as a sulfuric acid concentration.

Automation Products, Inc. uses the same reference tables used by oleum manufacturers to cross check results generated by our oleum correction software.The CL-10HY and Series 2000 combination have been used to measure oleum for chemical applications and acid mixing.

Our Dynatrol® density cells can be supplied with tantalum media contact parts as well as carpenter 20, stainless steel and other alloys that can be chosen for your specific application.

Ammonium Hydroxide

Dynatrol® Density Measurement Systems are used extensively for measurement and control of density, specific gravity, or percent concentration with Ammonia solution, also known as ammonium hydroxide, ammonia water, ammonical liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or simply ammonia.

  • Eliminate multiple hand sampling when mixing
  • Real time percent concentration measurements of ammonium hydroxide with no effects from pressure changes or pipe vibration
  • Virtually no maintenance costs

Automation Products, Inc. was approached by a chemical company to devise a solution for online measurement of an ammonia solution. The process is describer below.

Issue

The chemical company needed online measurements while mixing anhydrous ammonia with water. Their pressurized ammonia was bubbled into a mixing tank with ultra pure water, and a sample stream was constantly pumped from the bottom of the tank to give a real time reading of percent concentration for aqueous ammonia.

Resolution

The chemical company chose a Dynatrol® Density System to solve their problem. The Dynatrol® Density Meter has the Temperature vs. Density vs. Percent concentration curves programmed into the Series 2000 Digital Density Converter. The density meter provides 4-20 mA signals to the chemical company’s control room for percent concentration and temperature of the ammonia and water solution. Since the Dynatrol® Density Meter outputs percent concentration, there was no need to program a complicated set of algorithms into the DCS control system to calculate percent concentration from density.

After months of comparing hand sample measurements to the measurements of the Dynatrol® Density Meter, the company found that the Dynatrol® Density Meter correlated directly to the hand measurements. The company now uses the Dynatrol® Density System in the control of the mixing process. This eliminates the bi-hourly hand sampling that technicians would have to perform.
