Summary
Machine-generated summaryThis tender covers the purchase of liquid caustic soda at a concentration of 25%. The chemical is intended for use in the biogas washing process operated by the CDA. Biogas washing, also known as scrubbing, relies on caustic soda to remove impurities from the gas before it is further treated or used. The tender therefore concerns the regular supply of this chemical product to support the operation of the biogas treatment facility. Only one product type is described: 25% liquid caustic soda delivered for the CDA's biogas washing needs. No lots, quantities or duration are specified in the available description.
