Does any one have a good design to get rid of condensate from a building with no drains in northern minnesota?

What type of condensate steam, condensing boiler, ac.

No sewer, and no septic?

You need a long trap that can hold water and thaw itself with gravity pressure behind it. A pump might be necessary. Insulate the end that is outdoors.

After running the condensate through a neutralizer before condensate pump then into a drain

Yes as stated above it does need neutralized. But you can run it anywhere outside that you want. There will at times be ice, but it should flow as long as the the condensate can keep its heat and thaw the portion that may freeze. You just need it to collect it at times. When the thawing can't keep up. Which shouldn't be very often. You could dump it into an absorber filled with lime.

we live in northern mn so the temp here can get to -30 sometimes do you think it will still thaw and run

If it's insulated correctly and there is warm water behind it then yes.
If you use this setup and for some reason your having trouble you can get a heat trace cable and utilize that. I see it all the time here (iowa)

could you send me a simple drawing of this ? I thought just a holding tank with a pump that would push it out aways from the building at about 2 or three gallons at a time

Why neutralize it if it's dumping outside. Seems pointless
I presume it is to protect the grass or other plants.

AT -30, even if you can keep the run from freezing, with the ground frozen, it will pool, and make a nice ice pile!
From the condensate pump, have the line slope down as it goes outside so that it will drain itself. Don't try to drain it near any walkway or driveway or where it will end up on any concrete or plants unless you've run it through a neutralizer first. If it were to run down on a cement foundation, over time, it would literally start to dissolve it.
You could go through the wall into the house and dump it into a drain there...maybe the WM stand pipe?

100k btus about 1 gallon a day condensate. How far is the garage from house? Could pump it from boiler to 55 gallon plastic drum then to house with heat traced hose. Condensate is 4 ph and can damage equipment and septic system. Septic needs 6.5 - 7.5 for the bacteria.
