    Abstract: A fluid mixer for a reactor of a hydrocarbon processing plant includes a substantially cylindrical mixing chamber, at least one first inlet for conducting first fluid to the mixing chamber from above the mixing chamber and along a side wall of the mixing chamber to produce a spiral stream in the mixing chamber, at least one second inlet for conducting second fluid tangentially into the spiral stream, and an outlet channel for conducting the first and second fluids downwards out from the mixing chamber. The outlet channel is concentric to the mixing chamber and includes a mixing structure for enhancing mixing of the first and second fluids. At least a part of the mixing structure is located below an upper edge of the outlet channel and produces turbulence in a stream of the first and second fluids flowing in the outlet channel.

    Abstract: The present disclosure provides a process for producing hydrocarbons from a feedstock containing organic material of biological origin. The process includes: providing a feedstock containing organic material of biological origin; pre-treating the feedstock in one or more pre-treatment stages to obtain a purified feedstock; subjecting the purified feedstock to pre-hydrotreatment to obtain a stream of partly hydrotreated feed; subjecting the stream of partly hydrotreated feed to hydrotreatment to obtain a stream of hydrocarbons; distilling the stream of hydrocarbons to obtain at least two fractions, a first heavy bottom fraction which is removed from the process, and a second middle fraction, which is collected for further processing; and subjecting the collected middle fraction to isomerisation to obtain an isomerised stream of hydrocarbons.
