The technology supply for manufacturing water white resins comprises the supply comprises the supply for the Loop Reactor, a hot-filtration system for catalyst recycling, a stripping vessel, an evaporation system for evaporating the solvent and a solvent recovery system. Multiple plants have been built around the world and the technology was selected due to the high mass transfer rates, low catalyst consumption, high yield, low colors, and high productivity rates.

Typical reaction conditions in a Loop Reactor are:

temperature 200 – 340 °C
pressure 70 – 100 barg
1,000 – 1,500 psig
resin concentration 50 – 70 % in solvent
catalyst load 1.5 – 3 % Ni on resin
reaction time 90 – 180 min.
