How to purify natural gas, the ways used to do this, process description of each one, and the most common sweetening processes
In some hydrocarbon processing plants acid gas such as Hydrogen sulfide (H2S) and carbon dioxide (CO2) are present in the gas streams. They can also be organic sulfur in the form of carbonyl sulfide (COS). The streams can be natural and associated gases such as propane and butane, and products from upgrading of heavy oils, […]
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 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 […]
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 […]
FUEL GAS SYSTEM DESCRIPTION SCHEME AND FUNCTIONING It is one of the most important systems in any oil facility, because fuel gas is the main fuel for the whole plant, the most commonly used fuel in hydrocarbon treatment plants is natural gas because it is locally available and therefore financially more convenient than other fuels. […]
what is Gas Compressor Station? it is one of the most important steps in natural gas industry, it compresses natural gas and raise its pressure to make it continue flowing and reach further distances, they are located at natural gas pipeline, and they are essential to guarantee a continuous flow of gas, this is done […]
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. […]
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 […]
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 […]
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 […]
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 […]
