The Sulaway® unit
The Sulaway® unit is the heart of the Gazpack installation and is a patented process. The saturated, raw (bio) gas is inserted directly into the Gas Purifier. Via a pressurized process, using our patented Sulabeads® the raw biogas is converted into three different outgoing flows.
Gas vs. Electricity
1: Clean gas
The system is selective in the removal of sulfur (H2S) and reduces the percentage to a level of less than 3,5 ppmV, thus producing a green gas stream which is ready to be used, for example to generate heat in green houses or in an industrial process of a factory. Moreover, we can clean the green gas until it complies with the required Wobbe index (44-55 mJ/Nm3) which makes it possible to add to the natural gas network.
2: H2S gas
The Gas Purifier also produces a gas stream, which is highly saturated with sulfur (H2S). This gas stream is harnessed and burned off in the quencher. Extinguishing the resulting flame arc creates a sulfuric acid that is useful for a variety of applications including purifying ammonium-saturated air. The quenching heat can be used for the heating of offices, but also for digesting processes.
3: Sulphuric Acid
The third stream that comes out of the Gas Purifier is water. This water is used to extinguish the fire arc within the quencher and make sulfuric acid. The essence of the Gazpack system is that it is a closed loop system that produces a limited amount of waste compared to other gas cleaning systems. Waste disposal, especially when saturated with sulfur, is costly and environmentally unfriendly. The sulfuric acid can be used for a variety of applications such as battery acid.
The Sulaway® unit is built according to the highest quality and safety standards in the industry. The main features of the package are explained below.
