A large-scale upgrading solution: SULAWAY®
The Sulaway® unit is the heart of the Gazpack installation and fully customer specific. Our Suluway® is built to convert large capacities of biogas to biomethane (>1500 Nm³/h). Therefore, a wide range of capacities can be achieved. Thus, we can offer solutions for large-scale upgrading and the system can handle high H₂S content.
1: Grid injection
In order to comply with the climate commitment made at the COP21 in Paris, all gas supply must by renewable and decarbonised by 2050. Therefore, Gazpack is delivering a high-quality system which can provide a biomethane purity up to 99.5%. Moreover, we can clean the biogas until it complies with de Wobbe index (44-55 MJ/Nm3), which
makes it possible to inject it into the gas grid.
2: C02 recovery
Additionality, our Sulaway® system must remove CO2 to deliver high quality biomethane. The carbon gas can be liquefied and stored, which means an extra stream of revenue is feasible within our system. Due to liquification of our high-quality CO2, it is possible to use it for green houses or sell it to the food and beverage
3: Acid Water
The third outgoing stream of the Gas purifier is H2S, which is transformed into acid water by our quencher. Acid water can be
used for fermentation, as well as for batteries.
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
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.
