Given 7kPa per 1 element I bet on those are not coated with plastic but made of instead as buckling is not an issue. The perforated plastic ~1/4" sheets squeezed with plastic spools by long studs and inserted in a piping straight run.
Assuming the turndown 1:2 the pressure drop per element is 1.5 kPa. Wondering how can 2nd liquid dispersing be possible at 1.5 kPa? Given the 1st liquid viscosity is 100 times higher than water one how low the LL surface tension should be to provide any dispersing of any degree at 1.5 kPa? Is it physically achievable?
1,5 kPa is the pressure a cup of espresso (total 150g) with bottom diameter 5mm puts on a table desk.

I love
@rika kose whose topics have always been being so immense, so impressive. So contrast to the topics nearby: "
10 or 11 cfps is preferred?" or "
should I pick up globe or gate valve?". No,
@rika kose is not like that.
if a liquid then 100 times denser than water
if a mixing then 1:50 and in a pipe
if a dispersing then 1psi of pressure drop
if a fluid than a highly corrosive one and corrosive-immune fluoroplastics
if a price then 6 times difference
That is the scale, the real chem engineering challenges! Not a rat races at the neighbourhood. The brain is emerging from a rut, gears between the ears start turning and squeaking. Awesome. More such please.
But are you sure that
@rika kose is a human, not an AI conducting a behavioristic experiment?
