Abstract
Nickel carbonyl is separated in the liquid phase from a mixture of gases or vapours including carbon monoxide and nickel carbonyl by condensation at such a partial pressure of carbon monoxide in the condensation vessel that the vapour pressure of the nickel carbonyl is in the neighbourhood of the minimum for the condensation temperature. The concentration of carbon monoxide may be varied to give the desired partial pressure, or the pressure at which the carbonyl is formed may be raised or lowered to the optimum value and condensation effected at this pressure. Where the carbonyl has been formed at this optimum pressure, no adjustment will be necessary. For condensation temperatures of 0-40 DEG C., a partial pressure of 10--150 atm. gives good results. Preferably, the carbonyl vapour pressure is not greater than corresponds to 50 g. Ni per cubic metre of gas at N.T.P. above the minimum. Between 0--80 DEG C. the partial pressure of CO should be between 45 atm. less and 75 atm. more than corresponds to the minimum carbonyl vapour pressure. According to examples: (1) Gases from an atmospheric pressure nickel extraction plant containing nickel carbonyl equivalent to 420 g. Ni per c.m., are compressed at 0 DEG C. to 55 atm. and separation then effected. (2) Gases from a high pressure plant containing carbonyl equivalent to 450 g. Ni per c.m. at 250 atm. and 80 DEG C. are expanded to 70 atm. at atmospheric temperature and separation then effected.
