SDS Separation at the GPAE Annual Conference 2023

We are delighted to announce our participation in the esteemed GPA Europe Annual Conference.

SDS Separation at the GPAE Annual Conference 2023

When: 9th to 11th October
Location: BASF SE, Ludwigshafen, Germany
Speaker: Piet Geerts
Presentation Time: October 10th 2023, 1:00 pm, Hall 1
We are delighted to announce our participation in the esteemed GPA Europe Annual Conference.

Piet Geerts will be at the forefront of our representation, presenting our white paper titled, "RotaSep for Combined Liquid and Solid Separation from Gases without Replaceables or Shutdowns." This discussion promises to unveil our advancements and deep insights into gas separation technology.

Presentation Summary:
RotaSep is grounded in next-generation gas-liquid and gas-solid separation technology. It employs a rotating internal mechanism coupled with centrifugal forces to separate 1 micrometer fine particles from gases, ensuring the protection of sensitive equipment such as compressors. The standout performance of RotaSep, especially in bulk gas flows, results in notably compact separation packages. These packages demonstrate enhanced performance and offer distinct advantages, particularly at higher operating pressures.

After achieving a 99.5% certified separation of 1μm particles in a demo unit earlier this year, RotaSep marked a significant improvement in its capacity to extract liquids and fine solids from a natural gas stream on a North Sea offshore platform. Conventional methods using filter cartridges and multi-stage cyclone internals could not achieve this level of performance without recurring shutdowns and extensive maintenance. RotaSep addressed these challenges and was the only technology compact enough for the available space. These results highlight RotaSep's potential in platform technology, suggesting its capability to serve a wide range of processes in both current and renewable gas processing infrastructures.

For those keen on the latest developments in gas separation and eager to connect with industry leaders, we warmly invite you to attend this significant event.

RotaScrub ® Upgrade of the Medium-Pressure Inerts Washing System of a Snamprogetti Urea Plant

The SDS Separation RotaScrub ® is a highly efficient solution for gas washing or scrubbing. Based on the proprietary separation technology of the RotaSep®, RotaScrub ® adds a specific surface area up to 10 times higher than the next best solution and uses up to 30% less scrubbing liquid. This results in RotaScrub ® being up to 10 times smaller than the conventional packed scrubber beds, making it the most compact, robust, and efficient scrubbing solutions on the market.

The benefits of the RotaScrub ® Upgrade of the Medium-Pressure Inerts Washing System of a SnamprogettiTM Urea Plant are:
  • Increase safety standards (intrinsically safe design against explosions)
  • Reduce ammonia emissions from 2-4 vol% to 0.2-0.4vol% (90% efficiency) based on one co-current RotaScrub ® or to 0.02 to 0.04% based on two RotaScrub ® unit in series.
  • Reduce NOx emissions in case inerts stream is used as fuel
  • Reduce ammonia consumption figures of your urea plant
