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. Field: Area of one or more reservoirs related to same structural feature. Pool: Contains one or more reservoirs in isolated structures. Wells can be classified as gas […]
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 of standardizing […]
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, […]
Natural gas is a subcategory of petroleum that is a naturally occurring, complex mixture of hydrocarbons, with a minor amount of inorganic compounds. Geologists and chemists agree that petroleum originates from plants and animal remains that accumulate on the sea/lake floor along with the sediments that form sedimentary rocks. The processes by which the parent […]
PROCESS DESCRIPTION OF GAS DEHYDRATION The principle of glycol dehydration is contacting a natural gas stream with a hygroscopic liquid which has a greater affinity for the water vapor than does the gas. Contactor pressure is subject to economic evaluation usually influenced by water removal duty, required water dewpoint, vessel diameter and wall thickness. After […]
Liquefied petroleum gas (LPG) includes propane, butane, butadiene, isopropane, propylene, and vinyl chloride monomer, which are all by-products of the production of oil and natural gas. LPGs have a variety of uses including as a cooking/heating fuel, refinery feedstock, automotive power, and numerous other plastics and chemicals applications. another definition of LPG is that LPG […]
