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.

Power Plant

Dynatrol® instruments provide Bulk Solids Level Measurement of fly ash applications, Density Measurement of water treatment chemicals, various liquors and lime slurries and Viscosity Measurement of fuel oil and waste oil.

Bulk Solids Level Detection

Dynatrol® CL-10DJ series level switches are used for fly ash applications in power generation plants and for fly ash collection. These level indicators are also used in applications where fly ash is used as a filler. Our CL-10DJ level probes are made from high strength stainless steel. For more abrasive or corrosive service, our level switches can be made from other materials. These level switch probes are well suited for the high temperature and harsh environments that are always a part of fly ash applications.

Density Measurement

The Dynatrol® CL-10HY Density Cell and Series 2000 Digital Density Converter can be used to measure density, specific gravity or percent solids of water treatment chemicals such as caustic soda or sulphuric acid. Our equipment is also used to measure black liquor, green liquor and lime slurries, etc. at process conditions.

Our application software is written to use temperature and density information that comes from the CL-10HY cell to calculate various units at process conditions

Viscosity Applications

The Dynatrol® CL10-DV series Viscosity Meter and Series 3000 Viscosity Digital Converter are used to measure the viscosity of fuel oil in fuel oil to burner applications. Thus, helping to increase combustion efficiency and decrease particulate emissions. Dynatrol® Viscosity Systems are also used in waste oil incineration and waste oil pumping applications.

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.

Sulfuric Acid

Dynatrol® Density System can be used to measure sulfuric acid. The sulfuric acid application software is written to use the temperature and density information that comes from the CL-10HY cell to calculate product baume, density at a reference temperature, specific gravity and percent concentration.

Automation Products, Inc. uses the same reference tables used by sulfuric acid manufacturers to cross check results generated by our sulfuric acid software. The CL-10HY and Series 2000 combination have been used to measure sulfuric acid for automobile batteries, and low concentration sulfuric acid mixing. It has also been used to measures high concentration sulfuric acid in chlorine drying towers as well as very high sulfuric acid concentrations in mixing and make up applications. The Dynatrol® Density Cells can be supplied with tantalum media contact parts as well as Carpenter 20 and other alloys that can be chosen for your specific application.
