Preparation and anti-coking application of sol–gel SiO2 coating in a delayed coking furnace

A Mechanistic Approach to Delayed Coking Modelling

The valorisation of oil distillation residues constitutes a major problem for refineries. Thermal processes like visbreaking and delayed coking are still quite diffused technologies. This paper presents some major aspects of the delayed coking kinetic modelling and some preliminary results compared with experimental data. A mechanistic approach has been adopted; it allows describing the process...

Control System of Coking Plant

The reduction of cost in the process of iron manufacture is of permanent interest in steel-making industry. An important part of the overall cost in the process of iron manufacture is the cost of production of metallurgical coke. This problem is solved by finding a new technologies of iron production (COREX) or optimization of current ways of iron production. Therefore we have adopted the metho...

Prediction of the Products Yield of Delayed Coking for Iranian Vacuum Residues

In this work, new correlations are proposed to predict the products yield of delayed coking as a function of CCR and temperature based on the experimental results. For this purpose, selected Iranian vacuum residues with Conradson carbon residue (CCR) values between 13.40-22.19 wt.% were heated at a 10 °C/min heating rate and thermally cracked in a temperature range of 400-500 °C in a laboratory...

Environmental Control and Emission Reduction for Coking Plants

Characterisation of coking activity during supercritical hydrocarbon pyrolysis

The active cooling of the Supersonic Combustion Ramjet engine, for hypersonic flight purpose, is ensured thanks to fuel, n-dodecane for the present study. The endothermic fuel pyrolysis, starting above 800 K, could generate an unwanted coke formation. Experimental tests up to 1125 K and between 1 MPa and 6 MPa have been performed on the hydrocarbon fuel pyrolysis to evaluate the coking activity...
