A pyrgeometer is a device that measures near-surface infra-red (IR) radiation, approximately from 4.5 μm to 100 μm on the electromagnetic spectrum (thereby excluding solar radiation). It measures the resistance / voltage changes in a material that is sensitive to the net energy transfer by radiation that occurs between itself and its ...
Stack Tank Oil (STO) density (or API) may also be used by regulatory bodies to classify oil and oil products. Other properties such as Molecular Weight , saturated aromatic resin and asphaltene (SARA), refractive index , wax appearance temperature, asphaltene precipitation, and acid number , are also specified at Stock Tank conditions.

A Horton sphere (sometimes spelled Hortonsphere), also referred to as a spherical tank or simply sphere, is a spherical pressure vessel, which is used for industrial-scale storage of liquefied gases. Example of materials that can be stored in Horton spheres are liquefied petroleum gas (LPG), liquefied natural gas (LNG), and anhydrous ammonia .
An external floating roof tank is a storage tank commonly used to store large quantities of petroleum products such as crude oil or condensate. It consists of an open- topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid. The roof rises and falls with the liquid level in the tank. [1]
Crude oil is classified as light, medium, or heavy according to its measured API gravity. Light crude oil has an API gravity higher than 31.1° (i.e., less than 870 kg/m 3) Medium oil has an API gravity between 22.3 and 31.1° (i.e., 870 to 920 kg/m 3) Heavy crude oil has an API gravity below 22.3° (i.e., 920 to 1000 kg/m 3)
Central oil storage (COS), or central storage, is the term used for a communal heating system that began to be utilized in the middle of the twentieth century. The term also applies to industrial, plant and agricultural applications, all of which may or may not be communal in nature.
They are collapsible, flexible storage bladders (also known as tanks) that provide transport and storage (temporary or long term) for bulk industrial liquids such as fuels. Standard fuel bladder tanks sizes range from 100-US-gallon (380 L) to 200,000-US-gallon (760,000 L) capacities and larger.
Oil tankers generally have from 8 to 12 tanks. [1] Each tank is split into two or three independent compartments by fore-and-aft bulkheads. [1] The tanks are numbered with tank one being the forwardmost. Individual compartments are referred to by the tank number and the athwartships position, such as "one port", "three starboard", or "six ...
