چکیده انگلیسی
This short communication provides elemental mercury equilibrium solubilities in 1-hexanol, 1-decanol, 2-propanone (acetone), 2-[(propan-2-yl)oxy]propane (diisopropyl ether), and 1-butoxybutane (dibutyl ether) over the approximate temperature range, 255-333â¯K. Exponential expressions of the solubility are presented in the form: Solubility (ng/g)â¯=â¯Aext, where t is in â°C. In a low temperature separator at a gas field, mercury partitioning has been modelled. At separator temperature and pressure conditions of 263-267â¯K and 2600-3100â¯kPa, â¼94â¯wt% of the mercury is calculated to report to the vapor phase, whilst â¼3â¯wt% each reports to the condensate and aqueous phases. The aqueous phase consists of H2O-rich monoethylene glycol (36â¯wt% MEG) used to inhibit gas hydrate formation. Sampling and analysis show that the H2O-rich and H2O-lean MEG streams contain predominantly particulate mercury. The use of this technical information is critical to planning for mercury removal, decontamination and waste minimization.
