1. What is LNG to Gas Conversion?

LNG (Liquefied Natural Gas) to gas conversion calculates the volume of natural gas that results when LNG is regasified. The expansion ratio accounts for the volume increase when LNG changes from liquid to gaseous state.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• LNG Volume — Volume of liquefied natural gas in cubic meters (m³)
• Expansion Ratio — Typically around 600 (unitless)

Explanation: LNG expands approximately 600 times when converted from liquid to gas at standard temperature and pressure.

3. Importance of LNG Conversion

Details: Understanding the gas equivalent of LNG volumes is crucial for storage capacity planning, transportation logistics, and energy content calculations in the natural gas industry.

4. Using the Calculator

Tips: Enter LNG volume in cubic meters and the expansion ratio (default is 600). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical expansion ratio for LNG?
A: The expansion ratio is typically around 600, meaning 1 m³ of LNG expands to about 600 m³ of natural gas.

Q2: Does the expansion ratio vary?
A: Yes, it can vary slightly depending on the exact composition of the LNG and the temperature/pressure conditions during regasification.

Q3: How accurate is this calculation?
A: This provides a good estimate for most purposes, but for precise engineering calculations, more detailed thermodynamic models may be needed.

Q4: What's the energy content of the resulting gas?
A: The energy content depends on the gas composition, but typically 1 m³ of LNG contains about 22-24 GJ of energy, equivalent to about 600 m³ of natural gas.

Q5: Can this be used for other cryogenic liquids?
A: No, this calculator is specific to LNG. Other cryogenic liquids have different expansion ratios.
