For renewable gas producers, profitability often depends on seeing the process clearly. When methane slips, moisture swings, or inconsistent gas quality go unchecked, plants burn more energy, shorten recovery intervals and lose production. A new webinar from Vaisala explores how real-time, on-site measurements can stabilize RNG and biogas operations while cutting OPEX.
“The key to managing operating costs and maximizing production is to operate the upgrader under as stable conditions as possible,” said Antti Heckel, Vaisala’s product line manager for industrial decoration.
Hykel ä went through the process chain (from digester to injection), showing how a few well-placed sensors can make the difference between stable uptime and constant trouble detection. Methane, carbon dioxide and moisture measurements directly reveal small performance shifts in each digester that help operators fine-tune feed rates, mixing and heat before they become major problems.
Downstream, moisture measurement drives reliability. Many sites rely on a chiller approach to control drying, but this rarely matches the actual dew point. Over-drying can waste energy and reduce the efficiency of activated carbon, while under-drying leads to condensate, corrosion and clogging.
The same applies to upgrading. Real-time chi and moisture readings at the inlet act as gatekeepers to the membrane and PSA system, preventing poor-quality gas from triggering stop-start cycles, the leading cause of methane slip and lost production. Off-gas monitoring then verifies separation efficiency and helps meet emissions reporting.
Traditional extraction analyzers, with hot lines and moisture traps, add cost and delay. Vaisala’s optical, in-pipe sensors simultaneously measure Ch, Co, and Ho, and compensate for vapor interference in real time. The result is faster control response, fewer sampling points and less auxiliary power.
For RNG operators, health pays. Meeting ±1–2% accuracy standards informs when to replace digesters, adjust compression or service dryers. Treating measurement as a control asset, not a compliance function, can return value in months.
