24/08218 - Framework Agreement on Sorbent Delivery for deodorization units

The Contracting Authority wants to purchase new sorbent – including delivery – according to the specified technical data. Sorbent must be delivered to the specific plant unit. Due to excessive production of biogas in the distribution grid in Denmark, Energinet Gastransmission A/S has installed compressor stations with deodorization units to remove the Tetrahydrothiophene (THT) to inject the biogas in the main gas transmission grid. The THT is added to the gas as a tracing tool for safety purposes in relation to domestic household. THT is not allowed in the transmission system. All existing biogas compressor stations are located on mainland Denmark or connected to mainland by bridge. The existing stations are in the following cities: • St. Andst • Terkelsbøl • Odense SØ • Viborg • Karup Any future biogas compressor stations will also be located on mainland Denmark or connected to mainland by bridge, and comprises the following stretches: Nybro – Amager (West-East) Aalborg – Frøslev (North-South) The existing deodorization units consist of two vessels each filled with sorbent material which adsorbs the THT. Over time the sorbent will be saturated and will need to be exchanged. Each vessel is initially designed with a capacity for approximately one year of operations which means that it is expected that one vessel per unit needs to be exchanged each year. However, a decreasing gas consumption and increasing biogas production in the distributions grids means that a higher frequency can be expected over the duration of the Agreement. See further information in Appendix 2: Scope of Delivery and Appendix 2A: Safety Data Sheet.
