A sour gaseous stream comprising H2S is contacted in column 2 with an aqueous reactant solution comprising an effective amount of Fe(III) chelate of an organic acid to obtain a sweet gaseous stream and a mixture including solid sulphur and Fe(II) chelate of the acid. Degradation of the iron chelate in the reactant solution employed in the cyclic processes for H2S removal from sour gaseous streams ...

An aq. alkaline liq. soln. consists of water, at least 75 g/l NaM3O4 and sufficient NaOH for all Mn residueto be removed from the surface of material contacted with the soln. by acid neutralisation. A resinous substrate (e.g. epoxy/fibre glass) is prepd. for metallisation by contacting it with the soln. for desmearing resin from the inside walls of holes, cleaning holes of a multilayer circuit boa...

An electronic part is successively plated with Ni, Co and Au and is then annealed, at up to 450 deg.C for 10 mins. in N2 gas atmosphere. The Ni, Co and Au layers have respective thicknesses of 2-5. 0.5-2 and 1-3 micron. The part is a metallised pad of W or Mo formed on a ceramic substrate and then sintered. Annealing step avoids Au-Si eutectic crystal formation in later pellet bonding operations.
