Description
Technical field
The utility model belongs to oil-gas exploration technology and chemical field, and in particular to a kind of separation of Hg in natural gas mentions
Pure lines system.
Background technique
Hg in natural gas vapor content is as a Natural Gas Origin identification beacon early in 1974 by former Soviet Union scientist
Н А ο з р o ь а is proposed after having studied a large amount of oil gas fields: mercurous mercury very universal and with higher contains in petroleum, natural gas
Amount, usually above mercury content in atmosphere (background value of mercury is 1.5-2.0 nanogram/cubic meter in atmosphere) 2, even more numbers
It is more than magnitude.China researcher has studied in a large amount of petroliferous gas and coal-type gas after mercury vapor content in the early 1990s in last century
Summary obtains: the mercury content in coal-type gas is generally higher than the mercury content of petroliferous gas, and coal-type gas mercury vapor content is generally higher than 700
Nanogram/cubic meter, petroliferous gas mercury vapor content are usually less than 600 nanograms/cubic meter, accordingly using Hg in natural gas content as day
One auxiliary identification beacon of the right comprehensive identification beacon system of the gas origin cause of formation, and approved and applied in China.With research
Deeply and expand, petroliferous gas mercury content is generally 4 nanograms/- 142000 nanograms of cubic meter/cubic meter, coal-type gas mercury content one
As be 200 nanograms/- 3000000 nanograms of cubic meter/cubic meter [12,18], the natural gas mercury content of two kinds of origin causes of formation has no obviously
Difference is difficult the origin cause of formation accurately both identified according to Hg in natural gas content, and illustrating this index, there is uncertain and not
The apparent defect such as perfect and limitation.
With the accurate analyses for receiving Inductively coupled plasma mass spectrometry (MC-ICP-MS) to mercury isotope, the same position of mercury more
Element research obtains a series of research achievements to attract people's attention, such as to worldwide coal, air, forest defoliation, soil, moss, lake
