Special Focus: Maintenance and Reliability

Three topics for operational excellence related to a Cr-Mo hydrotreating reactor
Lee, S., Kim, E., Jeon, S., SK Energy

Many end users are trying to use feedstock with higher sulfur content for their refineries to increase profitability, but numerous unknown or plausible bottlenecks exist.

Advanced steam system optimization program

The steam system forms an integral part of the safe, reliable and profitable operation of a process plant. Steam constitutes approximately 30% of the energy used in a typical petroleum refinery.

Instrumentation reliability: A systematic approach

Many challenges exist in maintaining instrumentation reliability.

Mechanical design and fitness-for-service assessment of steam reformer pressure components
Aumuller, J., Carmagen Engineering, Inc.

Bulk hydrogen (H2) production in a petroleum refinery by steam methane reforming utilizes high temperatures, moderate pressures and catalyst-filled tubes that generate high tube temperatures of up to 920°C (1,690°F), imposing relatively harsh performance demands on system components.

Process Control and Instrumentation

Using valve diagnostics at startup to save time and money

Early detection of valve problems with diagnostics prevents small issues from escalating into major incidents when production starts.

Process Optimization

Speed up the development of new commercial adsorbents—Part 2

In the conventional development approach, a multi-stage process begins in the laboratory, moves to the pilot plant and then ends at the commercial unit, often before any financial benefits are realized.

Create a network of dividing wall columns in complex process units
Kalita, R., GTC Technology US LLC

The majority of dividing wall column (DWC) applications in the refining industry consist of standalone columns, whether a retrofit or a grassroots column.

Configuration study and design of sour water stripper units for a refinery revamp

As demand for oil products increases, refiners are expanding the capacity of their crude processing facilities to accommodate higher throughput.

Project Management

Creating a ‘win-win’ between construction contractor and project owner—Part 1
Shahani, G., Berg, J., ShureLine Construction; Rentschler, C., Engineering Consultant

Numerous articles have been written about the key elements to a successful construction project.
