Six large coke drums at Chevron’s El Segundo refinery, which supplies 20% of Southern California’s vehicle fuel, were showing signs of aging after 46 years in service.
Although many olefin plants are making big investments in hardware and metallurgy to improve compressor performance and to extend run lengths, the reliability, efficiency and throughput capacity of the CGC are still key influences on plant profitability.
Since organic fouling cannot be completely eliminated, ethylene producers must use operational, chemical and mechanical methods to minimize heat transfer losses and equipment downtime.
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.
Operators with permanently-installed continuous corrosion monitoring systems have better understanding of the corrosion and erosion rates occurring within their facility.
Once water enters the system, even at high temperatures, the insulation system can retain large quantities of water. That can then lead to accelerated heat gain or loss.

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.

Should the US allow exports of crude oil? (At present, US companies can export refined products derived from crude but not the raw crude itself.)
