✦ Synopsis

Aboluta atrnmplictea (1 ntm. P 700 mm.

mercury).

A basis is thus obtained for calculating tho. dimensions of a series of oxidation chambers, i t being assumed thit oxidation and ribsorption are conductcd alternately in separato operations as i n tlio experiniental plant.

Lct Z=vol. of gas passin through the chamber per sec., measure$ a t its pressuro and at 30° 0. n,=l\O-contcnt of gascs entering, i n vol. per cent. a,=KO-cvntent of exit gases, in rol. per cent. a=NO-contont of gas aftcr tho nth stngo. p=degreo of oxidation, i.e., proportion of NO osidised t o X02. tP,a= tirno of oxidation corresponding to NO-content a, in secs.

V = totnl oxidation space.

Va =correeponding oxidation space.

From equations (3) and (4) written i n the form : GN0,+3H,O =3HN0,+3HNO, 3HN0, = HNO, +2NO+H,O wo seo that of tlio six mols. of nitric oxido oxidised, two mols. aro regonerated. That is, after tho n t h Stag0 v o = z. tp, 0.

According to Tablo IV. tho oxidation titno can bo ro\yritten tp a-K in wliich K is a constant, therefor0 ~a=1;.K, und tho totiil oxidation spnco is
