New product developments in the hydrocarbon processing industry.
The Alfa Laval OLMI heat exchangers will be used to increase the yield and recover energy in the production of ethylene at the Turkmenistan project, according to company officials.
Intensifying performance demands in refineries, coupled with the ongoing decline in crude oil quality, require a new and improved duplex SS grade to withstand increasingly tough operating conditions. This need has led to the development of hyper-duplex stainless steels.
Frequent failures of the waste spray nozzles in incinerators result in accelerated degradation of the refractory lining, requiring unscheduled shutdowns for repairs. A study was carried out to identify the factors that contributed to the nozzle failure and to prevent the reoccurrence of similar failures in the future.
The Alfa Laval compact heat exchangers will be used for heat recovery in the process where heavy crude oil is upgraded to ultra-low sulfur transportation fuels.
The intention is to close the site in Artern, Germany, by July 31 2015, while consolidating the heat exchangers business with another site in Germany. The change will affect about 70 employees.
The Alfa Laval Packinox heat exchangers will be used in the production of mixed Xylenes, ingredients in the manufacturing of synthetic nylons and PET bottles.
With this closing and with assumption of the activities of GEA Heat Exchangers, Triton takes over all companies in the former group, as well as all staff.
Since organic fouling cannot be completely eliminated, ethylene producers must use operational, chemical and mechanical methods to minimize heat transfer losses and equipment downtime.
This case study shows how the installation of an unique piping and lance design achieved targeted liquid injection, quenched vapor hot zones and reduced resid entrainment into the heavy coker gasoil product.

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
