LNG Natural gas, which is comprised primarily of methane, is one of our most abundant natural resources, both domestic and abroad. Unfortunately, many of the natural gas reservoirs are located in relatively remote areas, or offshore, and high transportation costs tend to prohibit extensive use of this potentially valuable resource. To overcome this limitation, the Department of Energy’s […]
Necessary Conditions and Goals of Processing : The types of treatments carried out on gas streams usually are: separation; – heating; – inhibition. – dehydration; – liquid hydrocarbon recovery; – sweetening. Treatment needs and objectives: The first gas treatments are temporary. Their aim is to prevent the hydrates formation and they’re classified as follows: […]
Hydrates Hydrates are crystallized, compact, porous and rather light mass, similar to compressed snow. They are made of water, hydrocarbons, H2S and CO2. Unlike ice, hydrates have an unusual characteristic: they form at a temperature that is above water freezing point . For instance, they can form at 20 °C at particular pressures. When they are […]
A natural gas is called sweet gas if it has no sour components such as H2S, CO2, mercaptans, but is almost exclusively composed of methane, low amounts of ethane, propane, inert gases (N2) and traces of heavier hydrocarbons. It is generally saturated in water at reservoir temperature and pressure. A natural gas is usually defined as […]
Natural gas is a mixture of methane, with lower amounts of other hydrocarbons and other substances. These other constituents modify the physical and chemical characteristics of natural gas, for example, inert gases make the natural gas heating value lower. The substances that can be in natural gas are: • Carbon dioxide • Nitrogen • Hydrogen […]
Definition of Natural Gas Dehydration the removal of water from natural gas by lowering the dew point temperature of the natural gas Objective: To prepare natural gas for sale, its undesirable components (water, H2S and CO2) must be removed. Most natural gas contains substantial amounts of water vapor due to the presence of connate […]
Natural Gas Terminology: Reservoir: Porous & permeable underground formation containing an individual bank of H.C.s confined by impermeable rock or water barriers characterized by a single natural pressure system. read also What is Natural Gas Field: Area of one or more reservoirs related to same structural feature. Pool: Contains one or more reservoirs in isolated structures. […]
GTL: GTL means Gas to Liquids. A whole range of fuels can be produced from Natural gas by partial oxidation to synthesis gas (a mixture of H2 and CO) and subsequent conversion of this gas • 1993 – Shell pioneered the GTL business at their Shell Middle Distillate Synthesis Plant in Bintulu. In this plant […]
Introduction to Gas Treating When talking of gas treating, it is most often implied that natural gas is the focus. The natural gas industry is one of the World’s largest. However, there is also treatment of gas in the synthesis gas industry, and there are a number of processes used for this that are similar […]
what are Hydrates Introduction to Hydrate Natural gas hydrates are ice-like materials formed under low temperature and high pressure conditions. Natural gas hydrates consist of water molecules interconnected through hydrogen bonds which create an open structural lattice that has the ability to encage smaller hydrocarbons from natural gas or liquid hydrocarbons as guest molecules. Interest […]
The natural gas market world-wide is huge. Although there is a need to provide a standardized gas such that all the end users’ gas burners will function as intended, there are regional differences in specifications. The US market has this challenge that makes the interchangeability of gases difficult, and the cost and feasibility […]
What is LNG? Liquefied natural gas, or LNG, is natural gas in its liquid form. When natural gas is cooled to minus 259 degrees Fahrenheit (-161 degrees Celsius), it becomes a clear, colorless, odorless liquid. LNG is neither corrosive nor toxic. Natural gas is primarily methane, with low concentrations of other hydrocarbons, water, carbon dioxide, […]
