“…The green line indicates specification for sales quality gas (0.1 μg m -3 mercury). 27 This allowed a smooth transition to full plant implementation using 30 m 3 of a SILP (see Figure 11). After three years of continuous operation, the outlet mercury concentration from the plant remained low, meeting the plant outlet specifications.…”

An ionic liquid process for mercury removal from natural gas

Efficient scrubbing of mercury vapour from natural gas streams has been demonstrated both in the laboratory and on an industrial scale, using chlorocuprate(II) ionic liquids impregnated on high surface area porous solid supports, resulting in the effective removal of mercury vapour from natural gas streams. This material has been commercialised for use within the petroleum gas production industry, and has currently been running continuously for three years on a natural gas plant in Malaysia. Here we report on the chemistry underlying this process, and demonstrate the transfer of this technology from gram to ton scale.

Phosphonium Chloromercurate Room Temperature Ionic Liquids of Variable Composition

The system trihexyl(tetradecyl)phosphonium ([P 66614 ]Cl)/mercury chloride (HgCl 2 ) has been investigated by varying the stoichiometric ratios from 4:1 to 1:2 (25,50,75, 100, 150, and 200 mol % HgCl 2 ). All investigated compositions turn out to give rise to ionic liquids (ILs) at room temperature. The prepared ionic liquids offer the possibility to study the structurally and compositionally versatile chloromercurates in a liquid state at low temperatures in the absence of solvents. [P 66614 199 Hg NMR, Raman-and UV−vis spectroscopy, and cyclic voltammetry, among other techniques, and their densities and viscosities were determined. The [P 66614 ]Cl/HgCl 2 system shows similarities to the well-known chloroaluminate ILs (e.g., decrease in viscosity with increasing metal content after addition of more than 0.5 mol of HgCl 2 /mol [P 66614 ]Cl, increasing density with increasing metal content, and the likely formation of polynuclear/polymeric/ polyanionic species) but offer the advantage that they are air and water stable.

Donor-acceptor (D-A) complexes between 3,4-dicyano-1,2,5-chalcogenadiazoles [chalcogen=Te (1 a), Se (1 b), S (1 c)] and the pseudohalides CN and XCN (X=O, S, Se, Te) were studied experimentally and theoretically. For 1 a, they were isolated as [K(18-crown-6)][1 a-CN] (2), [K(18-crown-6)][1 a-NCO] (3), [K(18-crown-6)][1 a-SCN] (4), [K(18-crown-6)][1 a-SeCN] (5), and [K][1 a-NCSe] (6) and characterized by X-ray diffraction (XRD), UV/Vis and NMR spectroscopy, and DFT and QTAIM calculations. For 1 b and 1 c, the complexes were not isolated due to unfavorable thermodynamics. In all isolated complexes, the D-A bonds, stabilized by negative hyperconjugation, were longer than the sum of the covalent radii and shorter than the sum of the van der Waals radii of the bonded atoms. In mixtures of 1 a, F , and SeCN , the complex [1 a-F] was selectively formed in accordance with thermodynamics. The reaction of 1 a with SeCN and the cyclic trimeric perfluoro-ortho-phenylene mercury afforded the complex [K(18-crown-6)][SCN]⋅(o-C F Hg) , which was characterized by XRD.
