Greenlane Renewables Inc., a global provider of biogas desulfurisation and upgrading systems, has announced that its wholly-owned subsidiary Airdep S.r.l. has received new purchase orders totalling over US$2 million (€1.3 million).
The purchases were made by a repeat customer for the supply of multiple units of proprietary biogas desulfurisation equipment to support the production of renewable natural gas (RNG). Order fulfillment is expected to commence immediately.
"Our aim at Greenlane is to make RNG projects more accessible and scalable by solving the industry's most challenging technology problems, one of which is biogas desulfurisation," said Brad Douville, CEO of Greenlane. "All biogas projects require hydrogen sulfide (H2S) removal and our biogas desulfurisation product line has set the standard in Italy and is increasingly being adopted in global markets. According to the International Energy Agency, Italy is the fastest growing biomethane market in Europe. Our biogas desulfurisation product line delivers a proven and reliable regenerative solution where the goal is high H2S removal performance at low cost."
Our biogas desulfurisation technology includes the following process steps. The raw untreated biogas feeds into the bottom of a scrubbing tower where it flows, countercurrent, to a proprietary liquid chemical solution. Treated gas exits through the top of the scrubber. The sulfur-rich liquid solution is regenerated in a separate oxidation tank after which it is transferred to a sedimentation tank to allow the elemental sulfur solids to drop out. Clean, regenerated solution returns to the scrubbing tower in a continuous and efficient process.
The process neither requires the addition of oxygen nor adds it to the treated gas. This is critical because oxygen is difficult and costly to remove after being added in alternative approaches to H2S removal such for biological scrubbers or injection directly into the digester. Excess oxygen can lead to pipeline shut out due to non-compliance with injection specifications.
Our biogas desulfurisation systems are easy to install and operate and eliminate many of the operational issues and costs that come with traditional biological scrubbing and media-based H2S removal systems. The elemental sulfur solids created in the removal process can be spread on fields as fertilizer.
