Natural gas production

Natural gas production and transmission systems are complemented by underground storage systems. These systems provide the capabdity to respond to short-term gas demands which exceed the immediate production levels or transmission capabdities. They also provide an opportunity to sustain some production by refilling the storage areas when seasonal temperature variations lead to periods of reduced gas demand. In the United States in 1990, there were 397 storage pools having a combined capacity of 2.2 x 10 (1). 

Plants in the United States are basicaHy iodine producers and must extract the solutions from deep (between 2000- and 3000-m) weUs. The depleted solutions are reinjected for environmental reasons and maintain the pressure of the exploitation area. In Japan, on the other hand, iodine is mainly a by-product of natural gas production, and the weUs are less deep (about 1500 m). Depleted solutions are often discarded into the ocean. Costs associated with deep weUs are relatively high, reaching 1.7 to 2.0 x 10 in the United States and up to ca 0.7 x 10 in Japan. 

Natural gas production is generally given in cubic feet or cubic meters (1000 ft = 1 Mcf = 28.3 m ). Reserves of a trillion cubic feet (Tcf)... 

About 20 percent of the world s natural gas production was exported during the late 1990s, three-quarters of it through pipelines, and the rest by LNG tankers. The former Soviet Union, Canada, the Netherlands, and Norway are the largest pipeline exporters, while Indonesia, Algeria, and Malaysia dominate the LNG trade. The largest importers of piped gas are the United States, Germany, Italy, and France Japan and South Korea buy most of the LNG. 

Other energy sector concerns are methane emissions from unburned fuel, and from natural gas leaks at various stages of natural gas production, transmission and distribution. The curtailment of venting and flaring stranded gas (remotely located natural gas sources that are not economical to produce liquefied natural gas or methanol), and more efficient use of natural gas have significantly reduced atmospheric release. But growth in natural gas production and consumption may reverse this trend. Methane has... 

Coiiimon-pool problems characterize many resources where it is difficult to define property rights to restrain access and use. In North America, common-pool conditions in oil and natural gas production are created when firms compete for hydrocarbons in the same formation under the common-law rule of capture (which also governs fisheries and many other natural resources).

The design objectives for the SMDS process were developed to exploit small or remote gas fields where the cost of liquefied natural gas production or a gas pipeline system is not warranted. In many of the present GTL applications this is not... 

The Beaufort-Mackenzie Basin hosts immense unconventional natural gas hydrate reserves that are often co-located with conventional petroleum resources. Osadetz et al. (2005) reported that the conventional resources are co-located with an immense gas hydrate resource estimated between 2.4 x 1012 and 87 x 1012 m3 of raw natural gas. Because the expected decline in conventional natural gas production from the Western Canada Sedimentary Basin cannot be replaced by conventional production from frontier regions alone, this immense hydrate resource offers a solution to replace the expected decline in conventional gas reserves. 

Majorowicz Osadetz (2001) reported that the Mallik gas hydrate-bearing deposit in permafrost regions tends to occur at depths of 700 m to 1400 m where the permafrost is 100 m to 900 m thick. The Mallik 2002 Gas Hydrate Production Research Well Program conducted scientifically constrained production tests of the natural gas from the Mallik gas hydrate deposit, which is situated in the Mackenzie Delta on the coast of the Beaufort Sea, Northwest Territories, Canada (Dallimore et al. 2005a Satoh et al. 2005). Gas hydrate production tests demonstrated the potential for possible commercial production. Japan intends to establish commercial production from gas hydrates within the time frame of conventional natural gas production from the Mackenzie Delta (Yonezawa 2003). 

At planned volume of gas production of 115 billion cubic meters per year, the critical loads for nitrogen will be exceeded and this exceedance will be about 200 eq/ha/yr in year 2015. No sulfur exceedances will be projected at planned natural gas production.

The Department of Energy also transferred two of the Naval Oil Shale Reserves in Colorado to the Department of the Interior s Bureau of Land Management. Like other federally owned lands, these properties are offered for commercial mineral leasing, primarily for natural gas production and future petroleum exploration. 

The National Renewable Energy Laboratory, found that forecourt hydrogen production at fueling stations by electrolysis from grid power was most expensive, at 12/kg with forecourt natural gas production at 4.40/kg.

The hydrodesulfurizer will, in the presence of hydrogen, convert the thiophane into H2S that is easily removed by the zinc oxide polisher. The required hydrogen is supplied by recycling a small amount of the reformed natural gas product. Although a zinc oxide reactor can operate over a wide range of temperatures, a minimum bed volume is achieved at temperatures of 350 to 400°C (660 to 750°F). 

Biogas or synthetic natural gas production can be accomplished by utilizing the process of anaerobic digestion to convert biomass into methane. This multistage process of anaerobic decomposition involves hydrolysis of complex organic compounds by multiple bacterial species. The bacteria are grouped into the following classes ... 

Two sets of typical operating conditions are used for the simulations presented. These are shown in Table IV and will be referred to as standard type I or II conditions. Type I corresponds to operation at moderate to high temperatures, pressures, and flow rates with relatively low inlet CO and H2 concentrations and small amounts of inlet CH4, C02, and HzO either from recycle or from the upstream process. Type II is based on conditions for the industrial use of methanation in synthetic natural gas production. Note that the inlet methane concentration is much higher than in type I.
