DEFINITION |
| British Thermal Unit (BTU) |
Refers to low temperature and low temperature technology. There is no
precise temperature for an upper boundary but -100oF is often used.
|
| Cryogenic |
A Btu is the amount of heat required to change the temperature of one pound
of water one degree Fahrenheit.
|
| Density |
A description of oil by some measurement of its volume to weight ratio. The
industry usually relies on two expressions of oil's volume-weight relationship-specific
gravity and API degrees. The larger a specific gravity number and the smaller an API
number, the denser the oil.
|
| Fahrenheit degrees (F) |
A temperature scale according to which water boils at 212 and freezes at 32
Fahrenheit degrees. Convert to Centigrade degrees (C) by the following formula: (F-32)/1.8= C.
|
| Impoundment |
Spill control for tank content designed to limit the liquid travel in case of release. May also
refer to spill control for LNG piping or transfer operations.
|
| Middle distillates |
Products heavier than motor gasoline/naphtha and lighter than residual fuel oil. This range
includes heating oil, diesel, kerosene, and jet kero.
|
| Mole Percent |
Mole is a short form of molecular weight. Mole fraction or mole percent is the number of
moles of a component of a mixture divided by the total number of moles in the mixture.
|
| MTPA |
Million Tonnes per Annum. Tonnes or Metric Ton is approximately 2.47 cubic meter of LNG. |
| MW |
Molecular Weight |
| Peakshaving LNG Facility |
A facility for both storing and vaporizing LNG intended to operate on an intermittent basis
to meet relatively short term peak gas demands. A peakshaving plant may also have liquefaction
capacity, which is usually quite small compared to vaporization capacity at such facility.
|
| Stranded Gas |
Gas is considered stranded when it is not near its customer and a pipeline is not
economically justified.
|
| Sweetening |
Processing to remove sulfur. Hydrodesulfurization, for instance, can produce sweet catfeed.
Caustic washing can sweeten sour natural gasolines to make them suitable for motor gasoline blending.
