Hydrotreaters / Aromatic Content Measurement

Hydrotreating is used to purify and saturate olefins and aromatics in all final and inter-mediate refinery feedstocks (diesel, jet fuel, naphtha, gas oil and coker feed). The pur-pose of saturating the olefins and aromatics is to reduce their presence in the hydrocar-bons and to improve the feedstock to the other refinery processes such as the catalytic cracker.

Real-time indication of the aromatic content of the hydrocarbon stream

Download the application note to learn how Vaisala K PATENTS® Process Refractome-ter provides real-time in-line indication of the aromatic content of the hydrocarbon stream. The refractometer provides Ethernet and 4-20 mA output signals that can be used for real-time process control adjusting either:

reactor temperature,
hydrogen make-up ratio or
the feedstock blend

to achieve the required aromatic ratio.
