Advantages of the Sulaway system

27 October 2017

The Sulaway® process has the ability to clean bio- and oil gas in a completely efficient way. The article below will outline 5 advantages of this innovative process.

Gas sweetening

27 October 2017

The Sulaway® process is suitable for sweetening natural sour gas in large capacities. With the possibility to process a large array of gas compositions the Sulaway® process is a unique system. Each installation is specifically designed and engineered to meet the incoming and required performance of outgoing gas. Depending on the composition and required H2S outlet values, one set of towers filled with Sulabead ® can handle up to approximately 15.000 Nm3/h of gas.
The core of our technology lies within the patented Sulabead® a unique Zeolite type of absorbent that is highly selective towards specific contaminants in the gas. Depending on the incoming gas stream the Gazpack Sulabead® has a guaranteed lifetime of 16.000 operating hours. Upon request and depending on feasibility in terms of heat consumption and process restrictions of the actual project, the bed can also be regenerated.

Two new installations

9 October 2016

Two new Gazpack installations are being purchased by customers in Germany and England for cleaning of gas produced by waste water and biogas produced by a paper factory. In both cases the Gazpack unit will provide clean gas that will be directly used making the existing gas turbines obsolete.


12 May 2016

The new Sulaway unit is installed, however the special anaerobe digester is not available. Biogas used is now delivered by the existing larger digester which is less efficient and provides a gas with lower Sulphur content. Gazpack is continuing with testing and optimizing the process of the current installation for future purposes.

Contract with Wageningen University

4 November 2015

Gazpack signed a contract with the university of Wageningen to install and test the Sulaway unit at one of their test farms. The installation will be fed with biogas generated from an anaerobe (oxygen reduced) digester. These type of digesters have a fast and high output of biogas with a high concentration of Sulphur (H2S). The high concentration of Sulphur is essential to make the production of Sulphur commercially interesting. The unit will be built according to the latest international safety regulations:
  • Shutdown of the system with Nitrogen
  • Leak free installation (no greenhouse effect)
  • Energy efficient installation due to insulation
  • Heated digester with mixer
  • No output of toxic gases

Demonstration unit one year in operation

2 May 2015

The demonstration unit built with the experiences of the first pilot project commissioned in 2010 is already one whole year in operation. The installation cleans biogas produced by manure and green waste. The acid water produced by the installation is delivered to a factory for the production of acid batteries.

In the current situation the amount of Sulphur generated in the digester is too low to make the production of Sulphur a viable and commercially interesting option.

Nevertheless, the fact that all output of the Gazpack installation can be used and no waste is generated demonstrates the commercial and sustainability benefits of the system.
This project was made possible by a contribution from the European Regional Development Fund as part of OP-South.
