Opportunities and Challenges for Advanced Biofuel Industry

Apr 3, 2012
Ashish Gupta
Biofuels have been criticized for leading to rise in food costs. Advanced biofuels steer clear of this controversy as they are produced mostly from non-food crops. The US government renewable fuel standard mandates 21 billion gallons/yr of advanced biofuels by 2022 while current production levels...

Refinery-Wide Topics for Profitability, Reliability and Safety

Apr 3, 2012
Mike Siravo
In this session we will review several case studies that will allow you to better understand the importance of process engineering and process safety basics. These examples will show specific pitfalls to avoid but also will open your thinking to properly consider the implications of other...

Problem As part of Saudi Aramco Yanbu Refinery Excellence Program, We Identified the platforming high RVP issue as one of the most critical problem than needed to be resolved with high priority. The high reformate RVP causes problems with gasoline blending leading to high RVP in summer months,...

Reducing CO2 Emissions From Refineries Through Chemistry Upgrade

Apr 3, 2012
Michelle Valenzuela
Despite the lack of a global greenhouse gas emission reduction agreement, regional schemes are moving forward to limit CO 2 and other GHG emissions to the atmosphere. In the United States, the state of California is moving forward with regulations that will cap emissions from installations...

Root Cause Study of Debutanizer Column Operational Upsets

Apr 3, 2012
Feridoun Fahiminia
The NOVA Chemicals Debutanizer Column at the Corunna site experienced operational upsets. Gamma scans revealed that the column had flooded, and upon opening the tower it was found that the bottom trays fouled. An investigation was initiated to identify the root causes of fouling as well as...

Amine Treating: A Technology Review and Tutorial

Apr 3, 2012
Richard Ackman
Removal of H 2 S and CO 2 from gas streams and liquid hydrocarbon streams is important in many industrial processes. Solutions of aqueous amines have been used for more than 70 years to remove these unwanted acidic components in refineries streams, chemical processing and gas purification...

Cryogenic Expander Application in Propane Liquefaction Process

Apr 3, 2012
Michael Cords
The use of cryogenic liquid expanders in the propane liquefaction process can increase the amount of liquefied product by reducing the boil-off losses. Current practice is to use a Joule-Thomson valve to reduce the high pressure condensate. Losses associated by throttling across a J-T valve result...

Equipment Life Extension Using Thermal Spray Aluminum to Mitigate CUI

Apr 3, 2012
Chris O'Rear
Corrosion under insulation (CUI) of carbon and low alloy steels is one of many failure mechanisms that decrease reliability and equipment life while increasing the cost of ownership. Carbon and low alloy steels are most susceptible to CUI when operated in or cycled through temperatures ranging from...
