In any process plant, fired heaters are generally considered to be one of the most optimally designed pieces of equipment.

Considerations for revamping shell-and-tube heat exchangers
Garrido, E., Summum Projects

Revamp projects are complex in nature, and demand a great deal of resources for successful completion.

Maintenance and Reliability

Does your control valve talk?
Almas, A., Palmela

Pneumatic operated control valves (POCVs) are consistently the most used control final element for process control across most industries—in some cases, they are also part of the safety instrumented systems (SISs) layer.

Carburization inspection robots for radiant tubes inside ethylene cracking furnaces
Tiyawongsakul, T., Rayong Engineering & Plant Service Co. Ltd.

In an olefins plant, the reliability of ethylene cracking furnaces is one of the deciding factors used to indicate whether or not the plant can be operated at its design productivity.

Role statements needed for reliability job functions
Bloch, Heinz P., Hydrocarbon Processing Staff

Experience shows that written role statements impart great value to industries that have reliability professionals on staff.

Water Management

Filter process streams to protect downstream equipment and improve product quality
Clements, M., Eaton Corp.

Throughout the petroleum industry, most discussions of filtration focus on the oil itself as it is extracted from the wellhead and refined into saleable products.

Process Control and Instrumentation

Identify the cause of liquid maldistribution inside packed beds
Pless, L., Tracerco

Diagnosing liquid maldistribution problems inside packed beds that can cause mass transfer efficiency loss is a challenge to process engineers.

The lost art of proportional band, and the accidental art of performance monitoring
Kern, A., APC Performance LLC

Most control engineers know that proportional band and controller gain are largely interchangeable terms—both terms refer to the proportional setting of a proportional-integral-derivative (PID) controller and are commonly used by control system manufacturers.

Environment and Safety

Rethinking the risk mitigation process and revitalizing operational safety
Planche, S., DuPont Sustainable Solutions

For the past 2 yr, oil prices have been in free-fall. At the time of writing, the WTI price is around $50/bbl, up slightly since OPEC’s May 2017 announcement to extend its September 2016 production cut of 2.2%.

Safety studies and the importance of closeout reports
Kunte, V. A., TATA Consulting Engineers Ltd.

In various types of process industries, processing, storage and transfer of large quantities of hazardous materials are inevitable.
