Selection of cooling water system for gas, petroleum and petrochemical plants located on coastline - Part 1

Safamirzaei, M., Namvaran P&T

Cooling water systems play an important role in today’s industry.

Assess remaining life for heater tubes

Patel, R., Singh, J., Ashutosh, Engineers India Ltd.

Refineries and petrochemical plants form some of the major sections of the hydrocarbon industry and consume much of the fuel that is burned in furnaces (heaters and specialty furnaces, such as reformers and crackers) to meet process heating requirements.

Develop reactor internals for optimizing reactor design - Part 2: High-performance mixing chamber

Ahn, E. S., Park, S. I., Song, I. C., Kim, G. B., Chang, G. S., GS Engineering and Construction

Most hydroprocessing reactors are fixed-bed reactors comprising several catalyst beds that are divided by quench zones containing mixing chambers that introduce a vapor-quenching medium.

Welded plate heat exchangers cut refinery process costs—Part 1

Plate and frame (P&F) heat exchangers were first manufactured 100 yr ago for use in the dairy industry.

Lessons learned from a refinery revamp project

Khan, M. S., WorleyParsons

Revamp projects are inherently challenging due to the numerous constraints imposed by existing equipment design and space limitations.

Maintenance and turnaround planning critical to successful ejector vacuum system operation

Johnson, E., Graham Corp.

Steam ejector vacuum systems are generally considered to be reliable and require little maintenance.

Process design consideration for a deep-cut vacuum distillation unit—Part 1

In the recent past, many US refineries have been reconfigured to process heavy opportunistic sour crudes.

Engineering Case Histories: Case 103—Addressing heat exchanger tube leaks

Sofronas, A., Consulting Engineer

Heat exchangers have multiple tubes with fluid passing through and over them that either heats or cools another fluid.

Methodology for model-based, real-time prediction of corrosion in heat exchangers

Holzer, G., Jeitler, E., Prozess Optimal CAP GmbH

In the chemical and process industries, gases or vapor mixtures must be cooled to temperatures near the water dewpoint in a variety of thermal unit operations.

Understand the installation of steam tracing for long-term application success—Part 2

Hannah, C. C., Perry, T. W., QMax Industries Inc.

One of the most misunderstood and misused components of conductive steam tracing systems is heat transfer compound (HTC).
