Natural Gas Prices and Calorific value

Natural Gas

Ali Yahya Jirjees* MSc. Petroleum Engineering.H.D.Petro.Eng / Kirkuk -University Natural Gas Price Natural gas commands an important position in the global primary energy basket. Natural gas prices are mainly a function of market supply and demand. As with any commodity, the prices of natural gas are also determined by the demand–supply equilibrium. However, it would …

Hydrate inhibitor injection system

hydrate inhibition injection

Hydrate Inhibitors The use of inhibitors is a common practice adopted in gas fields. The reasons are that the well fluids are almost always water saturated and at a rather high pressure. Therefore the cooling due to the fluid throttling at the wellhead choke valves and along the pipeline up to the oil or gas center make …

The Effects of Mercaptans on Various Metals

mercaptan

What is Mercaptan? for many oxygenated organic compounds, there are analogous derivatives in which sulfur replaces the oxygen atom. The derivatives are called “thiocompounds” (e.g., thioalcohols, thioethers, and thioaldehydes). Thiocompounds corresponding to the alcohols (e.g., methanethiol) also are called “mercaptans” because they easily form mercury salts and have been used to treat mercury poisoning. Mercaptans tend to have strong, repugnant odors resembling skunk spray, rotten egg, or rotten cabbage. …

the Technologies of Natural Gas Sweetening

amine unit

Natural Gas Sweetening Natural gas may contain high quantities of hydrogen sulfide H2S and/or carbon dioxide CO2. The presence of these compounds renders the gas a sour gas. This is specially because sulfur has such negative effects on the quality of the produced gas, that the concentration of both components have to be reduced from …

Gas Dehydration by Solid Beds method

Solid bed gas dehydration

 DEHYDRATION BY SOLID BEDS GENERAL This plant employs the same adsorbent materials used in the short cycle solid bed plant. The only difference between the two plants is the operating time. As a matter of fact, using the sova-bead as an adsorbent for a short time, we find that it adsorbs mainly hydrocarbons vapors (STRIPPING) on the contrary with …

Natural Gas Well Production Problems

natural gas

    Eng. AlSayed Amer The ongoing process of producing hydrocarbons from a well is a dynamic process and this is often evidenced in terms of changes in the rock or fluid production characteristics. Problems are frequently encountered as a results of many reasons will be discussed. Associated Production Problems There are three basic problems …

Converting Natural Gas to LNG

LNG ship

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 …

Natural Gas Processing

natural gas storage

    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: …
