What is Isobutane? i-Butane - What is the Use of Isobutane

What is isobutane? What is the use of isobutane?

Isobutane (i-butane) is an isomer of butane.

Isobutane is also an LPG - Liquefied Petroleum Gas - as are butane and propane.

The main use of isobutane is in refineries, as a gasoline – petrol – additive.

However, isobutane is different in some important ways.

LPG Gas Changeover Valves

The Which, What, Why & How To

In Australia, you would typically have two 45kg LPG gas bottles on a home. 

An LPG (propane) gas changeover valve controls which gas bottle is being used.

Here’s the important bit:

Used correctly, it keeps you from running out of gas.

How We Switched to All Gas in a Day

Gas Hot Water, Heating & Cooking All in One Day

My wife and a leaking electric hot water tank finally got me to stop procrastinating and install LPG gas on our home. 

At one fell swoop, we got gas hot water, cooking and heating. 

Here is the amazing part:

It was all done in only about six hours!

Homeowners Abandon Natural Gas & Save with LPG - LPG vs Natural Gas Price

Is LPG cheaper than natural gas? Natural gas is generally cheaper than LPG for the gas itself. However, natural gas suppliers require a daily supply charge for being connected to the mains gas network that can exceed $400 per year, before any gas is used.

The LPG vs natural gas price comparison shows LPG cheaper than natural gas in many cases. Under $200 per year for LPG vs natural gas price of $539 per year, in one cooking only example.

LPG compared to natural gas has more than double the energy content at 93.2MJ/m³ vs natural gas at 38.7MJ/m³, so LPG is much more efficient than natural gas and is now cheaper in many cases.

Comparing LPG vs natural gas, natural gas price is no longer the presumed low cost option. Higher natural gas tariffs and daily service charges make LPG the best choice in many situations.

Prices will vary based on the tariffs in your area but LPG vs natural gas price now finds LPG cheaper than natural gas in many situations.

The daily supply charge is a charge that applies for supplying gas to your premises for each day of the billing period, regardless of how much gas you use and can be as high as $1.22 per day¹ or $446 per year and this doesn’t even include the gas. Add in just the gas for cooking and it totals $539 total annual cost for natural gas. The corresponding LPG cost would be well under $200.

The gas world has been turned upside down with people abandoning natural gas and choosing to go with LPG.

Whilst it may sound pretty implausible, based on old wisdom, the reasoning is simple — they are saving money.

Gas Measurement Unit - Gas Unit - LPG Measurement Unit - How is LPG Gas Measured?

The gas measurement for methane (natural gas) is measured by volume in cubic feet or cubic metres. One cubic metre of natural gas is the volume of gas enclosed in a cubic metre at standard temperature and pressure. The gas measurement of gas reserves is measured in thousands or millions of cubic metres.

A gas meter is a purpose built flow meter. A gas meter measures the volume of natural gas or LPG – liquified petroleum gas used. Gas meters are used by all gas utilities to measure consumption in homes, industrial and commercial buildings.

The gas unit used in the sale of gas is based on the energy content or calorific value of the gas, not gas volume. The typical gas units for energy content are British Thermal Units - BTU - megajoules (MJ) or therms, not cubic metres or cubic feet.

The distinctive properties of LPG mean that it can be measured in a number of different ways. These include gaseous volume (meter), liquid volume, weight, energy content and pressure. For example, LPG for homes is frequently delivered in 45kg gas bottles.

Gas measurement units (LPG measurement unit) are cubic metres, cubic feet, British Thermal Units (BTU), therms, and PSI as well as litres, kilograms, megajoules (MJ), tonnes and kilopascals (kPa) for gas measurement. The LPG (propane) gas is measured by weight in kilograms, pounds, tons or metric tonnes as gas measurement unit.

LPG gas is measured by weight when sold in gas bottles or cylinders. LPG gas is measured in tonnes when stored or transported in bulk tankers or vessels. LPG gas is measured in litres when it is sold by volume, with correction factors for temperature.

Gas is normally measures at STP - standard temperature and pressure (0°C at 1 atm pressure) or NTP - normal temperature and pressure (20°C at 1 atm pressure). Gas well production is measured in terms of thousands or millions of cubic metres or cubic feet.

Billion cubic metres (billions of m³) is the gas unit for measuring natural gas reserves. In the US, they would use trillion cubic feet (tcf) or billion cubic feet (bcf) as their LPG gas measurement unit. The gas unit for measuring gas well production is in millions of cubic metres (millions m³). These would be, by far, the largest LPG gas measurement units.

On a smaller scale, with a gas meter LPG gas is measured in cubic metres. If the gas units are billed in MJ or kWh, it’s calculated based on 3.6 megajoules equalling 1 kilowatt hour.

LPG is sold and weighed in gas bottles based on the weight of the contents. Bulk LPG is stored and transported in large quantities and LPG gas is measured in tonnes or US tons. Tanker delivered LPG gas is measured by volume in litres, with density corrections for temperature.

A liquid propane gas measurement unit for liquid volume, LPG gas is measured in litres or gallons for gas measurement.

How to Check Gas Bottle Level - Gas Bottle Level Indicator - How to Tell How Full a Gas Bottle Is

LPG Cylinder Level Indicator - How to Check Gas Bottle Level

Ideally, a gas appliance is in use. Carefully pour the hot water down the side of the gas bottle. Feel the gas bottle from the top down. The steel will feel warm until you get to the gas bottle level, where it feels cooler. The gas bottle level is at the level where the temperature changes.

How to check your gas bottle level (gas bottle level indicator):

1. Fill a jug or bucket with hot tap water (more is better)

2. SLOWLY pour the water down side of gas bottle

3. Feel for temperature change with your hand

4. Where it's cold is the gas level. Near the top is good. No difference indicates empty.

QUICK TIP: On a warm humid day you may see a line of condensation, especially during and after use, as your gas bottle level indicator, without even using the hot water.

Be careful not to scald yourself with the hot water. Do NOT use boiling water when you check gas bottle level!
