Special Report: Corrosion Control

How caustic stress leads to failures of incinerator caustic spray nozzles
Maity, M., Al-Zahrani, E., Al-Meshari, A., SABIC Technology Centre

Frequent failures of the waste spray nozzles in incinerators result in accelerated degradation of the refractory lining, requiring unscheduled shutdowns for repairs. A study was carried out to identify the factors that contributed to the nozzle failure and to prevent the reoccurrence of similar failures in the future.

Extend heat exchanger lifecycle with hyper-duplex stainless steel
Perea, E., Sandvik Materials Technology

Intensifying performance demands in refineries, coupled with the ongoing decline in crude oil quality, require a new and improved duplex SS grade to withstand increasingly tough operating conditions. This need has led to the development of hyper-duplex stainless steels.

Evaluate the reliability of a reformer heater convection tube
Yoon, H., Nam, J., Kim, S., SK Innovation Co. Ltd.

The findings and analysis herein confirm that HDSS can extend material performance levels beyond existing SDSS grades, thereby reducing maintenance requirements and unplanned shutdowns for more productive and cost-effective operations.

Heat Transfer

Improve the operation of fired heaters
Malhotra, K., S & B Engineers and Constructors Ltd.

Fired heaters or “process furnaces” are used extensively by the refining and petrochemical industries. These heat transfer units generate the much needed process energy through the combustio..

Plant Design

Determine the design metal temperature for a secondary reformer
Sharma, B. K., Fluor Daniel India

An air-burning system should be designed so that there is no maintenance required between scheduled shutdowns every two years. To achieve this, a metal temperature study should be carried out for the design of the pressure parts and for the refractory design.

Process Control

Optimize online monitoring of base oil
Kim, H., SK Innovation Co. Ltd.; Fannin, G., Bartec Benke GmbH

Latter-model vehicles and new automotive engine designs now require higher-quality lubrication oils, such as Groups II and III. Demand for Group II/III base oils is increasing. To capitalize on the gr..
