Mechanical design challenges in high-temperature electric heaters

Pramanik, R., Contributing Editor; Srinath, N. R., China Petroleum Engineering Co. Ltd.

Electric heaters are used in the process industries as an alternative to fired heaters or process heaters—where the heating medium is either steam or any heating fluid—for some specific applications where the process duties are low but fluids are heated to high temperature.

Air-cooled heat exchanger under natural convection

Pramanik, R., Contributing Consultant

Determining whether or not to operate an air-cooled heat exchanger (ACHE) under natural convection is a challenge due to the limited information available for simulations of an ACHE under operation without fans.

Use CFD analysis to evaluate the impact of hot air recirculation on air-cooled heat exchangers

Chen, C-C., CTCI, Corp.

Air-cooled heat exchangers are widely used in the petroleum, petrochemical, natural gas and other industries for cooling purposes. In contrast to a water-cooled system, which consists of a traditional shell-and-tube heat exchanger and a cooling tower, an air-cooled heat exchanger uses ambient air as the main cooling medium.

HRSG water/steam sampling: Do it right or face potential consequences

Buecker, B., ChemTreat, Inc.; Powalisz, J., Sentry Equipment Corp.

Many large industrial facilities—including refineries, and chemical and petrochemical plants—are increasingly turning to co-generation for process steam and power production.

BASF and MAN Energy Solutions enter into partnership for construction of one of the world’s largest heat pumps in Ludwigshafen

This project is intended to make an important contribution to reducing greenhouse gas emissions, establishing the use of low-CO2 technologies in chemical production and reducing the site’s natural gas consumption.

Lummus Technology launches next generation of breech-lock high-pressure heat exchanger closure

Lummus Technology announced the launch of its Polaris breech-lock closure, a new technological upgrade applicable to its high-pressure heat exchanger equipment.

Uncommon lessons: Shell-and-tube heat exchangers—Part 2

Daru, K., Air Products and Chemicals, Inc.; Panchal, A., Independent Consultant; Gala, P., Reliance Industries Ltd.
