Propane Tips for Your Home and Business – PT 3

This is the third installment of a series of propane tips that will be posted to assist our friends and neighbors in getting the most from their propane energy systems.

Question: My family has just built our first new home. We have been very blessed.  We put a lot of money into this home and we want to do everything top notch.  Now, is there any advantage to finding a more expensive pressure release valve for my propane tank?  Are there different grades of propane pressure release valves?

Terry Garnett: I think what you’re referring to is a Pressure Relief Valve. The propane relief valve is a safety feature on the tank. It is designed to discharge excess pressure in the tank. They are all set to discharge at 250#s PSI. If you have a problem with a relief valve, for example, you don’t feel it’s discharging or it’s discharging to early, have your provider, who is licensed, effect that change.

Question: I’ve read that according to the EPA, that much of the sulfur dioxide in the atmosphere that produces acid rain is attributed to coal fired and electricity generated facilities.  How dangerous is propane regarding the pollution and acid rain in the atmosphere?

Terry Garnett: Propane is a fossil fuel and very environmentally friendly.

Question: Dear Mr. Garnett, I have read that propane is actually used quite a bit in our farming for the irrigation pumps and generators and everything like that.  Is propane actually used, how important is it?  Roughly what percentage is used our farm system?

Terry Garnett: Actually 80%, of our farms use propane in their operations today.

Question: Help me settle a debate with a co-worker, is propane more compact as a liquid or as a gas?

Terry Garnett: Great question, propane is purchased, delivered, and stored in a liquid form.  So what you buy is a liquid.  What you have in your tank is a liquid.  What is utilized is a vapor that’s achieved when propane leaves the system and goes through the regulator.   The expansion rate from liquid to vapor is 282 parts to one, so a little bit of liquid makes a lot of vapor. Propane is more compact in liquid form.

Question: When my propane provider delivers propane in a truck, are they putting a liquid or a gas into my tank?

Terry Garnett: They are putting a liquid into your tank.  What you are purchasing in gallons is liquid gallons.  And what you are using in your home is a vapor.

Question: It’s getting into the season where we like to do a lot of cooking outside and I like to cook steaks on the grill.  I’d like the cooking to move along.  Is there any kind of problem, I mean, if I’m spraying lighter fluid on the grill that’s a propane grill?

Terry Garnett: Probably not a good idea. Remind me to not have you cook for me.
