New technology in volatile filming corrosion inhibitors and lower-salting neutralizing amines can provide cost-effective solutions for the steam-condensate system and minimize the risk of amine chloride salt formation.
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.
This discussion tracks a material flow through the steam system, starting with feed and continuing with steam generation, steam uses and, finally, condensate recovery.
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.
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.
This article examines three applications where rigorous heat exchanger models can boost value derived from process simulation and provide more accurate results.
Improve operations by avoiding buildup of sensible duty or by using baffles

Engineers and designers are highly skilled individuals. Forcing them to enter design changes using tables, forms and spreadsheets is unproductive and uneconomical, and it increases the likelihood of human error—this is the way that most instrumentation software systems currently work. For too long, software vendors have denied engineers and designers the simple practicality of a graphical visual engineering interface with “drag and drop” capability and inbuilt intelligence, ensuring changes are automatically replicated into all the associated data and databases.

As low oil prices make naphtha cracking margins in Europe and Asia more competitive, are investments in new, ethane-based petrochemicals capacity in the US and Middle East becoming less attractive?
Yes, ethane cracking is less economical
No, ethane cracking is still the future
Too early to tell
