These liquefied gas calculation tools can be used to make various LNG calculations or to review the calculations of other parties. LoadGeni offers free LNG density calculations, LNG gross heating value and wobbe index calculations, LNG methane number calculations and LNG Energy unit conversions. Just fill in the data and get solutions on your LNG calculations.

From composition and liquid temperature

Liquefied natural gas can be kept in different conditions, what makes that the density of the liquefied natural gas can change. There are two types of influences on the density of liquefied natural gas (LNG), these are the LNG composition and the liquid temperature of the LNG. The composition is measured during the loading or bunkering operation and is shared as a composition report. The liquid temperature can change over time and is measured via temperature measurement devices.

From composition

Liquefied natural gas has different compositions depending on the production process and location on the earth where the LNG is produced. This makes that LNG has a mixture of impurities and heavier hydrocarbons mixed with the methane gas. The energy contained in the LNG changes for each composition as each product has its own energy values. The following calculation calculates the gross heating values and wobbe index from the LNG composition.

Liquefied natural gas calculations can be made in a lot of different ways with different types of international calculation standards. It is difficult to know the right results if you are not aware of the differences of these standards. The LoadGeni basic LNG calculation course introduces the participant to the main LNG calculation standards that are used in the world. The different ways of calculating are compared to understand the differences between those LNG calculation standards. Following the free basic LNG calculation course will make you understand the LNG calculations on this page better. After the completion of the basic course is it possible to go deeper in LNG calculations with the Advance LNG calculation course.

From composition

Liquefied natural gas (LNG) has different qualities and compositions depending on the place of production and production process. A duel fuel engine might react on this change in composition if the LNG is used as a fuel on board. A poor quality of fuel might result in knocking of the engines. This is why all types of LNG are specified with a Methane number. This Methane number, indicating from 0 to 100, is affected by the different components in the composition of the LNG. Most engines are able to run with a minimum methane number between 70 and 80.

Convert MJ, KWH and MMBTU between each other

The amount of liquefied natural gas (LNG) is commonly given in an energy value. This energy value is depending on contracts and place in the world given in mega joule (MJ), kilo watt hour (KWH) or million British thermal unit (MMBTU). These values might be a bit confusing but can easily be recalculated to each other.
