Development of next generation biogas cleaning and upgrading technology: demonstration of terpene removal
conference paper
Terpenes are a problem for biogas producers, as grid owners will refuse entry to the natural gas grid when more than a few ppm terpenes are detected in the renewable natural gas injected. The problems are related to the integrity of pipelines, safety at the upgrading plant and the fact that terpenes mask the odour of the standard added tetrahydrothiophene (THT) odorant in natural gas, which is unacceptable for grid owners, as it may lead to safety risks. Moreover, the technology currently used by most biogas producers is removal of terpenes with activated carbon, which is a costly process. The degree of remaining adsorbent capacity is hard to monitor, which leads to an increased risk of an occasional slip of terpenes.
