WASTE PRESSURE TO ZERO EMISSIONS OPERATION ELECTRICITY?

---

1) Divert some flow around an existing pressure loss in a natural gas pipeline.

2) A motor spinning backwards (i.e. electrical generator) in the expander generates electricity.

3) Return the natural gas to the pipeline for 50-500W; zero-emissions operation expected.

Conclusion: Reduce emissions by 6.4-7.4 tonnes CO2/100W/year by avoiding burning gas for site power! 

Full flow control and handling vary
