Flow alignmen and selec i e gas ou ing a e key challenges in gas cap u e and p ocessing
sys ems. T adi ional app oaches use mechanical o elec omagne ic de ices such as ans,

To add ess hese limi a ions, we p opose he AngleDome: a passi e geome ic low
condi ione designed o align and so gas molecules acco ding o hei di ec ion and mo-
men um—wi hou any mo ing pa s o ex e nal powe . The AngleDome ope a es using he
law o e lec ion, whe ein a gas molecule inciden a angle θin wi h a su ace inclined by β
exi s wi h a new ajec o y:
θou =θin −2β
A e mul iple e lec ions, he dome s uc u e p og essi ely educes angula dispe sion
o he gas low. This low alignmen e ec can be quan i ied by measu ing he educ ion in
angula s anda d de ia ion:
∆σθ=σθ,in −σθ,ou >0
He e, σθdeno es he dispe sion o molecula low di ec ion, and a posi i e alue o ∆σθ

In addi ion o low alignmen , he AngleDome in oduces in en ional momen um sepa a-
ion. Le pin ep esen he incoming momen um o a gas molecule, and pou i s momen um

Whe e ∆pis dependen on su ace angle βand molecula mass m. Hea ie CO molecules

Fo maximum dissolu ion e iciency downs eam, he inle o he solu ion chambe mus
