Targeted liquid injection improves shed deck performance

Valero Benicia Refinery: Riley, C.  |  Wicklow, C.
Valero Energy Corp.: Hanson, D.  |  Brown Burns, J.

This case study shows how the installation of an unique piping and lance design achieved targeted liquid injection, quenched vapor hot zones and reduced resid entrainment into the heavy coker gasoil product.

Case history: Optimization of aromatics complex

Neste Jacobs Oy: Bergman, S.  |  Yli-Opas, K.  |  Karlsson, S.  |  Frejborg, A.
Borealis Polumers Oy: Vettenranta, J.
Borealis Polymers Oy: Rönkä, M.

Borealis Polymers executed an online optimization project at its phenol and aromatics plants in Porvoo. The plantwide application increased the output rate by 9% and greatly improved the stability of operations.

Convert heavy oil residue into synthetic fuel

Expander Energy: Kresnyak, S.  |  Price, S.  |  Wagner, J.

Over the past several decades, oil extractors and refiners have been maximizing the production of easy-to-drill, high-quality light sweet oil, mostly concentrated on the Arabian Peninsula. With “..

Improve the isomerization of alkanes by catalytic distillation

St. Petersburg State Institute: Lisitsyn, N. V.  |  Chuparev, E. V.  |  Zernov, P. A.

The isomerization of light gasoline fractions is crucial to producing high-octane fuels and to reducing the benzene content in gasoline. One of the most promising options for isomerization is catalytic distillation.

Mitigate fouling in crude unit overhead—Part 3

CH2M Hill: Sloley, A. W.

CASE STUDYThe basis for this case study is shown in Fig. 18; it is a crude unit with overhead heat integration. This is a one-drum overhead system with heat integration and no water wash. In an attemp..

Mitigate fouling in crude unit overhead—Part 2

CH2M Hill: Sloley, A. W.

Up to 50% of the refinery’s entire corrosion expense may occur in the crude unit. The root causes of the fouling and corrosion issues are often linked to the basic unit configuration choices, as ..

Use APC in energy systems―Total’s Leuna refinery case study

KBC Process Technology Ltd.: Milosevic, Z.
Total: Polster, A.  |  Mai, A.  |  Seifert, U.  |  Wagner, M.

Advanced Process Control (APC) has been used extensively to assist in operating refinery and petrochemical processes safely and profitably. However, with the constantly increasing fuel and environment..

Mitigate fouling in crude unit overhead—Part 1

CH2M Hill: Sloley, A. W.

In a refinery crude distillation column, up to 40% of the total heat removal may be found in the tower overhead condenser. The quantity of duty available makes heat integration (HI) between the column..

Update: Russia’s capacity and modernization program

RAS, A.V. Topchiev Institute of Petrochemical Synthesis, Gubkin Russian State University of Oil and Gas: Levinbuk, M.
Gazprom Neft: Galkin, V. V.  |  Makhiyanov, V.

Since 2008, Russian regulations regarding the crude oil and refining industry have changed substantially. At present, Russia has 22 large refineries, each with an individual throughput capacity exceed..

Consider accurate feed characterization with improved simulation methods

Fluor Canada Ltd.: Ha, H. Z.
Canadian Natural Resources Ltd.: Tiwary, D.

Assay definition is crucial for accurate process simulations. The performance of process simulators depends on the feed definition to the processing unit. Modern analytical laboratories can offer comp..
