Notes:
- All m3 @ 101.325 kPa, 15°C
- ft3 @ 14.73 psia, 60°F
- 6 mg/m3 H2S equates to 4 ppm or
more specifically, 4.140 ppm
* TransGas offers "Low Heating Value Surcharge Service" that allows customers
to deliver gas onto the TransGas system which has a heating value below 35.0
MJ/m3. TransGas will generally approve this service at points on the system
where low heating value receipts will not compromise the quality of downstream
deliveries.
