Are you using pinch technology effectively in your daily operations?—Part 1

Milosevic, Z., Rudman, A., Brown, R., KBC Process Technology Ltd.

Pinch technology is the most rigorous, systematic and best documented methodology for process design.1–3 Nearly all optimization projects for heat recovery are conducted with some form of pinch a..

Consider novel CGC and front-end depropanizer system for olefins production

Xu, Q., Fu, J., Zhao, C., Lamar University

In the presented case study, an innovative design for an integrated CGC-DeC3 system introduces part of the heavier condensate from the early compression stages directly into the high-pressure (HP) depropanizer.

Enhance operation and reliability of dividing-wall columns

Lee, J. W., LG Chem, Ltd.; Lee, M., Yeungnam University; Shin, J., LG Chem.; Lee, S., LG Chem Ltd.; Lee, B., AMT Pacific Co. Ltd.

Dividing wall columns (DWCs) are an attractive option when the goals are to reduce energy consumption and capital investment for distillation processes. A major component in a DWC system is the reflux..

Improve the performance of your existing steam system

Pelham, R. O., Merrick & Co.

This discussion tracks a material flow through the steam system, starting with feed and continuing with steam generation, steam uses and, finally, condensate recovery.

Improve your plantwide steam network

Pelham, R. O., Merrick & Co.

When optimizing an existing steam network, design and process engineers need a complete understanding of all aspects of the existing system. Accurate energy and material balances must be established.

HP Water Management: Need a package boiler in a hurry?

Huchler, L. A., MarTech Systems, Inc.

Acquiring a package boiler is an unplanned event that requires process engineers to solve this completely unfamiliar problem. To reduce the chaos of replacing them, here are helpful ways to resolve this situation.

HP Integration Strategies: The energy water nexus

Miller, Paul, ARC Advisory Group

Whether or not you subscribe to the global warming and “peak oil” arguments, it is clear to almost everyone in the industrial world that “business as usual” is not sustainable inde..

A subsidiary of Foster Wheeler AG's Global Power group has been awarded a contract by Doosan Heavy Industries & Construction Co. Ltd. for cooperation in the design of a circulating fluidized-bed steam generator for Korea South East Power Co. Ltd.

What are the benefits of rigorous modeling in heat exchanger design?

Cazenave, J., Aspen Technology Inc.

This article examines three applications where rigorous heat exchanger models can boost value derived from process simulation and provide more accurate results.

Prevent external corrosion of boiler tubes under refractory lining

Maity, M., Biramov, K., Al-Zahrani, E., SABIC Technology Centre; Kareem, M. A., Eastern Petrochemical Co.

A leak developed on the water wall for several boiler tubes within five months of the commissioning of a plant boiler. In this case, the boiler tubes were partially covered with a castable refractory ..
