“…Only in ten of these deposits (8 %), the Hg concentration was above 10 μg/m 3 . The highest mercury content occurs in the deposits located in crossing deep faults zones that indicates the contribution of mercury-enriched deep mantle fluids in the gas pools formation [4,5]. In such objects, a big amount of liquid mercury can accumulate in the process equipment.…”

Mercury naturally occurs in gas and oil deposits in a wide range of concentrations covering six orders of magnitude: up to 5 mg/m3 in natural gas and up to 600 ppm (mg/kg) in crude oil. Mercury in hydrocarbons poses a number of technological and environmental problems: contamination of equipment and products with this extremely toxic element, poisoning of catalysts, and initiates intensive corrosion of technological equipment, thereby enhancing accident risk. Metal mercury causes rapid electrochemical corrosion of aluminum alloys (e.g., heat exchangers) and liquid metal embrittlement (LME) of steel leading to heavy accidents. The novel technology based on Zeeman atomic absorption spectroscopy enables rapid selective mercury determination in crude oil, gas condensate, naphtha and natural gas. Examples of the technology application for gas, oil and oil products are presented.

“…Sylvester-Bradley and King (1963) and Sylvester-Bradley (1964) also pointed out the frequent association of bitumen with cinnabar. This association was subsequently attributed to degassing of mercury and associate volatiles from the mantle (Ozerova et al, 1999). These findings led Sylvester-Bradley (1964) to conclude that oil is polygenetic but this poses the question of how much oil is biogenic and how much is derived from other sources and, perhaps more pertinently, other possible mechanisms for the abiogenic formation of oil.…”

. The two theories of abiogenic formation of hydrocarbons, the Russian‐Ukrainian theory of deep, abiotic petroleum origins and Thomas Gold's deep gas theory, have been considered in some detail. Whilst the Russian‐Ukrainian theory was portrayed as being scientifically rigorous in contrast to the biogenic theory which was thought to be littered with invalid assumptions, this applies only to the formation of the higher hydrocarbons from methane in the upper mantle. In most other aspects, in particular the influence of the oxidation state of the mantle on the abundance of methane, this rigour is lacking especially when judged against modern criteria as opposed to the level of understanding in the 1950s to 1980s when this theory was at its peak. Thomas Gold's theory involves degassing of methane from the mantle and the formation of higher hydrocarbons from methane in the upper layers of the Earth's crust. However, formation of higher hydrocarbons in the upper layers of the Earth's crust occurs only as a result of Fischer‐Tropsch‐type reactions in the presence of hydrogen gas but is otherwise not possible on thermodynamic grounds. This theory is therefore invalid. Both theories have been overtaken by the increasingly sophisticated understanding of the modes of formation of hydrocarbon deposits in nature.

“…Mercury extraction and purification of gases, as well as reworking the products of gas deposits, which involve mercury separating as a fairly toxic element, is very important for the environment protection (Spiric and Mashyanov, 2000). It is important even in cases when mercury is not an industrial component; the huge amounts of world annual reworking gas should be taken into account (Ozerova et al, 1999).…”

Problem statement: Mercury is not only hazardous to human health and the environment but could also attack equipment components resulting in a mechanical failure and gas leakage. Approach: Describes the preparation of various sizes and shapes of Au nanoparticles for mercury adsorption by using polyol method under MW heating. Au nanoparticles have been synthesized by a polyol method under Microwave (MW) heating in the presence of Au seed ([Au] 1 /[Au] 0 = 6 of molar ratio) and different Polyvinylpyrrolidone (PVP) concentrations (11.1, 22.2 and 33.3 mM). The amount of mercury adsorbed was determined by analyzing the concentration of mercury solution before and after the contacts with various sizes and shapes of Au nanoparticles. Results: When the lower PVP concentration (11.1 mM) was used, polygonal and spherical nanoparticles were dominantly present, while spherical nanoparticles were preferentially form by using higher PVP concentrations (22.2 and 3.33 mM). It was found that the diameter and length of Au nanoparticles decreased with increasing PVP concentrations. When Au nanoparticles solution was prepared using Au seed, significant changes in sizes and shapes of Au seed occurred. Spherical nanoparticles in the Au seed (22.2 mM) were completely changed to polygonal nanoparticles. The amount of mercury adsorbed using 9 ppm mercury solution on polygonal nanoparticles is higher (64.88%) than spherical nanoparticles (18.77%). Conclusion: These results indicated that mercury adsorption strongly depends on the sizes and shapes of Au nanoparticles. Polygonal nanoparticles adsorbed more mercury than spherical nanoparticles but the amount mercury adsorbed is inversely proportional to their size.
