SO3 Generator

For Industrial Applications and Laboratory Use

Produce SO3 gas online in small quantities

There is a wide range of application for gaseous SO3 in the industry. The strict conditions imposed by the EC in September 2017 on the use of hexavalent chromium (chrome VI) hit the industry hard and left many without a real solution for their process.

Pentol decided to scale down SO3 conditioning units designed for the power industry to a size where it can be integrated in industrial processes. Wherever SO3 is useful, e.g. for galvanization, glass production, pharmaceutical processes, Pentol is able to supply a reliable, highly efficient SO3 generator.

Unlike the production of SO3 based on Oleum, the Pentol process is safe and continuous. The quantity of SO3 is kept constant automatically by a sophisticated control system.

Pentol looks back at 50 years of experience in producing SO3 for large power stations. Recognizing the needs of the industry, Pentol has downsized SO3 generators small enough to be used in industrial processes. The SO3 generator is running fully automatic, providing a constant flow of SO3 in air gas available for your process.

The SO3 generator has been developed to comply with EC machinery directive and special emphasis has been put on SIL compliance, to allow an easy and safe integration into existing production plants.

Technology

so3-generator

The Pentol SO3 generator evaporates liquid SO2 from a gas bottle and dilutes it with compressed air. The mixture is heated and oxidized to SO3 by means of a catalyst. The SO3 generator is capable to process up to 150 l/h of SO2 in a mixture of max. 5 % SO2 in the air. The conversion rate to SO3 depends on the concentration and is typically 70%.

The Pentol SO3 Generator is controlled by a Siemens S7 PLC with a large touch screen, where it is operated and all parameters are logged. We added the possibility to create scripts for discontinuous processes, to add flexibility and integrate it into your process.

Safety

Special emphasis has been put in safety and reliability. If you are used to handle Oleum, you will be relieved to learn that the Pentol So3 Generator includes all safety features to lock down any SO2 or SO3 leak in the process. The unit is TÜV tested, designed according to SIL and European machinery directive and got CE certification.

Careful integration of the Pentol SO3 Generator requires thoughts not only about generation of SO3, but also about neutralization of the gas after use in your process. Our engineers are happy to assist you in the planning phase of your project.

Availability

Final performance tests of this unit have been so successful, that our Serial #1 unit never made it back to our workshop after the first industrial test but is now integrated in a galvanization plant.
Replace Oleum now to improve reliability and to reduce cost.
