Using a quantitative descriptive research design, the learner characteristics of preferred learning strategy and verbal-visual preferences of 291 working engineers were studied in relation to the demographics of gender, age, job position, ethnicity, native country, and native language. Learning strategy and verbal-visual preferences were measured with the ATLAS and the VerbalVisual Learning Style Rating instruments, respectively. The overall learning strategy preference profile for the engineers was 26.8% Navigators, 57.7% Problem Solvers, and 14.4% Engagers. This profile is statistically significantly different from the established distribution for the general population which is an approximately even split among the three strategy types. This suggests that learning content for engineers should include problem solving. The overall verbal-visual preference profile was 4.1% more verbal, 46.0% no strong preference, and 49.1% more visual. This profile is also statistically different from the general population and suggests learning content for engineers should include highly visual instructional materials. This paper reports on the relationships found between learner characteristics and demographics. It also includes recommendations for instructional practice and future research. © American Society for Engineering Education, 2015.

As a part of an initiative to conserve energy and other valuable resources, an independent petroleum refiner began a two-year training program in the summer of 2013 for more than 900 operators at six plants. In addition to improving the operational safety and management of furnaces, the program created a single point of leadership for fired heaters at each facility, who has the expertise and knowledge to lead the organization’s efforts on every aspect of furnace operation and integrity. © 2014 Hydrocarbon Processing.

Research has shown that engineers are considerably more visual than the general population and that engineers prefer more visual multimedia materials for continuing engineering education (CEE). These materials include, for example, photographs, drawings, videos, animations, and virtual reality. Research also has shown that multi-image presentations can enhance learning. Therefore, it is argued that multi-image presentations can enhance CEE. This paper reviews the relevant literature on multi-image presentations, describes how a multiimage presentation was used in a research study that considered CEE preferences, discusses the potential benefits and problems of using multi-image presentations, and provides some recommendations on how to use multi-image presentations in CEE along with some potential areas for future research. © American Society for Engineering Education, 2016.

The objective of this development program is to assess the feasibility of retrofitting burners for oxy-firing in process heaters. A secondary objective is to confirm this feasibility assessment by conducting single burner oxy-fired testing with flue gas recycle. The CO2 Capture Project commissioned the John Zink Company to conduct oxy-fired testing on two of their conventional process heater burners, a PSFG staged gas low NOx burner and a COOLstar® Ultra-Low NOx burner.

Several factors that should be considered while selecting flares that allow the safe and effective disposal of gases and liquids are presented. The specific design of a flare system depends on the type of flare. The major components include the flare burner, support structure, piping, and ancillary equipment. Flare design also depends on the sources of the gas being vented into the flare header and such gas characteristics as flowrate, composition, and temperature, the available gas pressure, and utility costs and availability. The additional design considerations may include hydraulics, liquid removal, air infiltration, smoke suppression, flame radiation, noise, and visibility, and need to ensure reliable burning. Flare system sizing must take into account the number of relief valves discharging into a common flare manifold or header. The pressure drop from each relief valve discharge through the flare tip must not exceed the allowable relief valve backpressure for all system flow conditions.

In conjunction with John Zink Co., LLC, the Chevron Energy Technology Company conducted a three part study evaluating potential issues with switching refinery process heaters from fuel gas to hydrogen fuel for the purpose of greenhouse gas emissions reduction via CO 2 capture and storage. The focus was on the following areas: • Heater performance • Burner performance and robustness • Fuel gas system retrofit requirements This paper will summarize the findings of the study. © 2011 Published by Elsevier Ltd.

The growing interest in supporting STEM disciplines creates an opportunity for professional organizations that include members from academia and industry to participate in the recruitment and engagement of K-12 students. Professional organizations, because of their industry partners and members, are often in unique situations to center on specific focus areas and are composed of individuals interested in service and outreach. Further, professional organizations are routinely managing present-day "issues" facing certain industries and / or focus areas, creating opportunities for disseminating "real-time" relevance to prospective young students. This paper highlights the efforts of one such professional organization - the Central States Section of the Combustion Institute (CSS/CI) - in creating and executing an Outreach Program that solicits and funds proposals from high school teachers who use the funds to augment their science / engineering classes with some exposure to combustion. The program, now in its fourth year with four successful competition windows, has created opportunities for members of academia and industry to become exposed to issues that K-12 educators face in terms of engaging students in STEM disciplines. The objective of this paper is to provide a guide for professional organizations that consist of members of academia and industry to use in creating their own outreach program and to identify opportunities for bridging the gap between professional organizations and K-12 students and educators. The paper describes the process for developing the CSS/CI program, summarizes "lessons-learned" and provides what are believed to be essential features for making a K-12 outreach program successful. © American Society for Engineering Education, 2015.

John Brown University (JBU) uses its engineering industrial advisory board in a unique fashion which is helpful for its students, fun for the board members, and useful for the faculty and university. During one of its regular Industrial Advisory Board meetings, JBU arranges an Open Forum Panel where students are encouraged to ask board members any questions they may have. These questions cover a very broad range of student interests including, for example, how to get an internship, what industry is looking for when hiring new graduates, the utility of getting a professional engineering license, and how to prepare for admission to graduate school. After a recent forum, a survey was given to the students with 61 responding. The overwhelming response was very positive and included suggestions for improving future forums. © American Society for Engineering Education, 2015.

There are many potential “rules,” or guidelines, for the safe operation of process heaters. American Petroleum Institute (API) STD 5601 and API RP 5352 provide many useful recommendations for operating heaters and burners, respectively. Companies normally develop their own detailed procedures based on API recommendations and their own experiences. These best practices can be summed up in four simple and easy-to-remember rules for operating fired process heaters. These rules are intentionally broad to encompass many of the more detailed procedures that have been developed for a particular heater, and they are especially useful for new operators that are learning the many facets involved with safely running process heaters. These common-sense guidelines are not intended to replace company procedures, but to provide a framework to more easily remember some of the more important factors in the safe operation of fired heaters. The focus here is upon safety,3 and not specifically, for example, on minimizing pollution,4, 5 or in maximizing efficiency6, 7 or uptime. However, these are often corresponding results of following the principles presented here. Examples are also provided for the potential negative consequences of not following each rule. © 2015 Hydrocarbon Processing.
