Natural Gas Prices and Calorific value

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 […]

teg dehydration operation problems and solutions

   Definition of Natural Gas Dehydration: Removal of water from natural gas by lowering the dew point temperature of the natural gas. Dew point ..is the temperature to which a gas must be cooled in order to become saturated with water. Note that the water content is directly proportional to the dew point … it […]

The Effects of Mercaptans on Various Metals

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

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 […]

LNG Liquefaction and Purification Processes

Introduction to LNG Processes  The refrigeration and liquefaction sections of any LNG project are very costly items of equipment. A number of cycles have been developed to achieve the low temperatures required. Brief descriptions of a small number of process routes will be give. Some twelve countries were operating by 2003. The cycles employed are the […]

Natural Gas Well Production Problems

    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 […]
