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.

Hallo Brian, Doug and list,
this looks amazing ! The filtering seems to be very good.
You and Doug seem to have experience with stocking producer gas.
May I ask you some questions ?
We have 5 separate houses/cabins on our land , all of them with solar and
individual wood and /or almond shell burning fireplaces .
All of them are hidronic underfloor systems with hot sanitary water tanks .
The distances between these houses make a central water heat distribution
system rather inviable.
We are off grid and run electricitywise on solar, wind and micro hydro.
There is a backup generator slow speed diesel running on WVO.
My idea is to connect all houses to a single gassifier of around 40 -50 kW gas
output and store a few hours gas in a gasometer and have the gassy start and
stop and run at close to full output as the gasometer level demands so as to
give it " an easy life " tarwise.
The clean and cool gas could run through ordinary PE pipes to the individual
houses where it should burn in gas furnaces.
A part of it could run the Listeroid genset which already works in chp mode.
I remember systems like this being built in Switzerland until 30-40 years ago
for large kitchens and heating boilers in hotels and other remote buildings
in the mountains. The manufacturer was located in Horgen on Lake Zurich.
I would have to dive very deep into my old records to find him...
I attended the Germany GEK workshop with Jim last year, but he seems to busy
to have time to spare for me. It is a pity.
Questions:
Do you have a gassifier of that range 40 - 50 kW gas, not engine kW ?
Do you think that after scrubbing the gas could be "compressed " slightly to
300-400 mb and stored in a gasometer ?
Has anybody sent producer gas through PE pipes over 150 m ?
Where do you expect the real difficulties ?
Looking foreward to your answer.
Rolf

To finger the problem of using industrial scale producer gas, is that
most large systems are not tar free, and if you need to compress the gas,
technical challenges come thick and fast.
Doug,
Oh goodness yes! We've not been willing to TOUCH the compression challenges
until we got our gas pretty darn clean. I'm cautiously optimistic with
where we are at on that task:

And right now we're planning on three separate compression steps with
additional filters between each step.
And thanks for the pointer to your archives, I will certainly browse!
