ODORANT INJECTION SYSTEM
|Inspection Item||Unit||Acceptable Limit|
|Calorific Value||MJ/㎥ (0℃, 101.3 kPa)||The calorific value shall be decided by the commerce minister,
the governor of a province or mayor based on Government Law 20-1.
|Wobbe Index||MJ/㎥ (0℃, 101.3 kPa)||51.50 ~ 56.52 (12,300 ~ 13,500 kcal/m3)|
|Total Sulfur||mg/㎥ (0℃, 101.3 kPa)||< 30|
|Odorant Concentration||mg/㎥ (0℃, 101.3 kPa)||
4 ~ 30 ( TBM+THT)
3~13 (MES+ DMS+TBM+THT)
If LPG is mixed in biogas to increase calorific value, following regulation can be applied.
4 ~ 30(MES+DMS+TBM+THT)
If city gas pressure is below 1MPa,
the sum of CO2, O2 and N2 can be < 3.53.(But O2 shall be < 0.5.)
|O2||mol-%||< 0.03 (LPG+Air : < 10 )|
|N2||mol-%||< 1.0 (LPG+Air : < 35)|
Local city gas and LPG must include the odorant (TBM+THT, LPG_MES+DMS having specific concentration to prevent gas leak and accident
Gaswell can supply odorant injection system to meet Koran regulation (4~30 mg/m3).
The odorant injection system is using direct liquid injection method and it can be changed by customer’s requirement.
Gaswell can supply the damage prevention equipment to decrease odorant smell diffusion.
