Description

Stream mixer

Purpose

Combines multiplestreams

into onestream

Divides feed based onsplits

specified foroutlet streams

Divides feed based onsplits

specified foreach substream

Separates feed into twooutlet

streams, usingrigorous

vapor-liquid

orvapor-liquid- liquid

equilibrium

Separates feed into three

outlet streams, using

rigorous vapor-liquid-

liquid equilibrium

Separates feed into two

liquid outlet streams

Determines thermal and

phase conditions of

outlet stream

Exchanges heat between

two streams

Use For
