[Gasification] DIY GtL

[Li CHEN]

Hi Rolf,

In China, there are hundreds of villages using fuel gas 
station...(gasifier --> producer gas --> pipe line --> end user).

I find some chinese documents about using pipeline to provide producer gas.

About pipeline part:, it uses:

 From gas tank to end user, outside underground pipeline: high-density 
polyehytlene (designed life: 50 years).

Inside or outside ground pipeline: steel pipe.

Pressure before end user gas burner: 100mm H2O.

I will send you offlist some figures about the gas storage tank figure.

Li
