Claim 1:
2. The process according to claim 1, comprising:
subjecting the product side stream to a stripping stage, where the product side stream is stripped with a stripping gas (H2) causing a stripped side stream to have ≤0.4 wppm nitrogen, measured as elemental nitrogen, and a lower nitrogen amount compared to the product side stream; and
isomerising the stripped side stream in the isomerisation reactor including the at least one catalytic zone, in which the stripped side stream and the hydrogen-rich gas having ≤1 ppm (mol/mol) nitrogen, measured as elemental nitrogen, are introduced into the at least one catalytic zone at the third inlet temperature and the third pressure causing at least hydroisomerisation to produce the first isomerised effluent.
