Process Design & Development

In 2006, the United States EPA mandated the use of 15 ppmw ultra-low sulfur diesel (ULSD) for on-road diesel fuel. At that time several refiners either revamped existing facilities or constructed grass roots facilities to meet the specification. Some facilities did not implement ULSD process...

A contributor to complex/large project management difficulty is uncertainty gaps – gaps between the information required and that readily available within the project organization. Moreover, for large projects, information is generally spread among many professional personnel across multiple...

Energy efficiency has become an important theme in the process industries, and many companies have implemented sophisticated strategies to improve both the design and the operation of their plants. However, many efficiency improvements are possible simply by doing basic things right. This article...

The Cultivation of Algae and its Conversion to Biodiesel Daniel Choi, Spencer Glantz, Jasmin Alsous, Warren D. Seider, Stuart W. Churchill Department of Chemical & Biomolecular Engineering, University of Pennsylvania A presentation at the 2010 Annual Meeting under the title &'The Production...

Oil sands operations in Alberta are poised to experience significant growth over the next number of years. Production of 1.31 million bbl/day of synthetic crude oil and bitumen blends from oil sands in 2008 is projected to increase to over 3 million bbl/day by 2018. This guarantees a large output...

Refineries and petrochemical plants are leading segment of the entire chemical process industry. It was reported that the value of the product shipments by refineries in U.S. accounted for 9.32% of the entire manufacturing sector of the U.S. economy in 2007. On the other hand, air emissions from...

Background Oxy-combustion is considered as one of the CO 2 capture options for the coal-fired power plants. The CO 2 -rich flue gas from such a plant will have to be compressed and purified for sequestrtion. Praxair is developing a near zero emissions technology that will produce CO 2 virtually...

In this work, production of lipid from Lypomyces starkeyi on soluble sweet potato starch was simulated in Aspen Plus simulation. A kinetic model based on experimental results of medium optimization and high density cultivation was used for cell growth and lipid production. The simulation...
