Description

The pilot plant steam cracker is used to determine the yields of cracking reactions and/or coke deposition in the radiant/convection sections of coils and the transfer line exchanger (TLE). The major advantage of the pilot is its extreme flexibility. A wide variety of hydrocarbons, ranging from gaseous feeds to hydrocarbon liquids and to  waxes, can be handled. The reactor design facilitates a wide array of process conditions, with normal hydrocarbon flow rates ranging from 3 to 4 kg/h and the capability to reach high temperatures up to 900 °C in the furnace. The pilot also offers the opportunity to test steam cracking of industrially new feeds, additives, optimization of process conditions, coatings, etc.

The setup comprises three sections: the feed section with feeding barrels and Coriolis flow meters, the reactor and furnace section, and the analysis section featuring online product analysis through gas chromatography with various detectors such as FID, SCD, NCD, and AED. Additionally, the system is equipped with a Refinery Gas Analyzer (RGA) and an infrared probe to measure light hydrocarbons, carbon monoxide and carbon dioxide in the product.
