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.

Project Management: Estimate skid and package dimensions

Abid, J., Engineering Consultant

In the absence of vendor quotations or detailed engineering, preliminary dimensions of skids or packages can be estimated quickly using the ratio method.

Fluid Flow: Retrofit for reliability with Coriolis flowmeters

Gentile, A., Emerson Automation Solutions

Aging infrastructure has become a much-talked-about issue across the hydrocarbon industry.

Application of ring-type joint gaskets in a refinery

Lee, S., Lee, S. H., Jeon, S., SK Energy; Jang, T. Y., SK Innovation Co. Ltd.

In refineries and petrochemical plants, ring-type joint (RTJ) flanges have been applied to high-pressure processes or sensitive areas that are susceptible to leaks.

Fabrication of clad equipment and piping—Part 2

Shargay, C., Carmona, R. K., Daru, K., Desai, J., Irfan, M., Fluor; Panchal, A., Reliance Industries Ltd.

For pressure vessels, heat exchangers and piping in corrosive services, the materials in contact with the process are often required to be high alloys to provide a reliable service life.

Design considerations for rigging and transportation of large process columns

Sharma, B. K., Bahadur, A., Fluor Daniel India

Design guidelines for rigging and transporting large process columns are outlined in this article, along with the various aspects that should be considered during the initial design phase of equipment.

Set correct design specifications for optimized piping and pipe support system

Maiti, S., Wood Group

During the planning and engineering execution of petrochemical, oil and gas, and power projects, it is essential that the owner and engineering, procurement and construction (EPC) contractor mutually develop a comprehensive and detailed piping design specification.

Engineering Case Histories: Case 105—Temperature distribution along a flare line

Sofronas, A., Consulting Engineer

During an engineer’s career, many interesting questions come up that may not have a ready or good answer.

Stable thermosiphon reboiler operation: With or without a valve in the inlet piping?

Kister, H. Z., Fluor Daniel; Van Doorn, E., Fluor

A reboiler provides the necessary heat duty for the separation in a distillation tower.
