Injection Points - Quill Orientation and Flow path Guidelines required

Injection Points - Quill Orientation and Flow path Guidelines required

(OP)
Hello,

We have a number of process injection points at our site, where an additive or water etc is injected into a process stream via a quill.

The process stream can either be vapour or liquid.

When selecting the quill orientation against the flow path (co or counter current) are there any design guidelines?

I thought that normally if it is a liquid being injected into a vapour, it is injected against the flow to allow dispersion and change of momentum (i.e not accelerate the liquid too much).

Any guidance would be appreciated.

Regards,
 

RE: Injection Points - Quill Orientation and Flow path Guidelines required

When using a quill we point it  upstream if in chemical process line and downstream if in a superheater.  When using a quill we like to be at least 5 pipe diameters from any bends.  
We have gotten way from using a quill and are using products from Komax.  We use their mixers in many process lines to eliminate water hammer, concentration effect, and others.
