Frequently asked questions

How to reduce gas consumption?
Preheat the feed water with condensate and blowdown heat, insulate the steam lines, monitor efficiency and excess air.

The calculations are approximate: they help to assess the process and compare options, but do not replace a process design and trials on a specific raw material. This section is for reference only and contains no commercial offers.
