6 A bayesian decision-theory-based digital twin for methane flares2022Ground flares operate in a high-turndown, standby configuration for a significant portion of their operating life, being fully utilized only under process upset scenarios or emergencies. The low-momentum flow results in poor fuel-air mixing near the flare tip, leading to decreased overall combustion...
7 A chemical kinetics approach for heavy fuel oils gasification modelling2022surrogate; HFOs; pyrolysis; chemical kinetics modeling; GassificationRefinery oil residue commonly considered the bottom of the barrel, can no longer be a waste. The increasing energy demand and the constant depletion of light oil supply make it crucial to find a suitable way to convert residual oils into valuable fuels. The gasification process represents a possible...

9 A volume of fluid approach to model injection of highly viscous fluids2022Despite the transition to renewable energy sources, fossil fuels will still play a significant role in satisfying the world's energy needs shortly. In addition, the rise in the demand for light distillates and the depletion of light crude oil reservoirs are shifting the interest toward the conversio...
10 AAU, associations, and members file amicus brief to support lawsuits against administration's H1-B visa restrictions2020-10-30The brief supports the complaint filed by Purdue University, the University of Michigan, and Indiana University and 14 other plaintiffs against the Labor Department's rule that would make it more difficult for high-skilled foreign workers with college degrees to acquire H-1B visas.
11 Advanced emissions monitoring from elevated gas flares for early warning system and optimization of plant operations2019Real-time monitoring of emissions from elevated gas flares is very difficult and expensive due to the relative location of the source and the cost to collect samples for analysis. Elevated Analytics has developed and applied a UAV based sensor system to accomplish this task. Besides providing a snap...
12 The advantages of monitoring flare pilots with instantaneous response2020This paper will discuss applications for and details of a fiber optic pilot monitoring system that addresses known, specific challenges in the market. For decades, thermocouples have been the most widely accepted device for determining flare pilot status. However, there is a growing desire in the in...
13 An air-assisted flare for biomass gasifiers2019Computational fluid dynamics (CFD) was used to simulate the combustion practice of the gases that produce from gasification process. In this simulation a new air-assisted flare design which capable to handle low flowrates of these gases with high performance was used. The simulated cases were perfor...
14 Analysis of burner operation inside an enclosed ground flare2022Thermo-Acoustic Coupling; Enclosed Flare; LES CFD Model; Noise; Premixed BurnerAn industrial enclosed ground flare used as part of a large refinery project has been analyzed to assess combustion stability and performance under low and high flow conditions. This flare includes a large combustion chamber directly above the burner deck with Low Flow (LF) burners that fire up to 9...
15 Analysis of design and operation of multi-point ground flares2022Multi-point ground flares (MPGF) are used to process large quantities of hydrocarbon gases generated in chemical processing or petrochemical refining. These flares use hundreds of flare burners arranged and fired in a staged fashion. A wind fence surrounds the MPGF to shield the flames from plant op...
16 Capturing the effect of near-and far-field dynamics on the combustion efficiency of multi-point ground flares2022Multi-point ground flares are frequently used in scenarios where flare gas flow rates can be high and pollution (noise, light, smoke) needs to be minimized. We have applied Arches, a large eddy simulation (LES) tool that we have developed for capturing the dynamics of flares (turbulent mixing, local...
17 CFD development for fired heater applications2022Industry values the ability to ‘virtually' verify and optimize burner performance through CFD simulation and to evaluate the suitability of burner and furnace designs. Inaccurate results may lead us to falsely reject good burner designs or accept a poor design. Field problems can be far more expen...

22 Effect of operating parameters on fired heater tube skin temperature measurement accuracy & the development of new improved tube skin thermocouple2022Refineries are often faced with challenges to meet production target, improve efficiency, process opportunity crudes with limited information on fouling characteristics etc. The common parameter that often becomes constraining are the tube skin temperatures which are critical in maintaining the inte...
23 Experimental investigation for the development of burners for low scale reheating of semi-finished metal products2019recuperative burner; fuel rich combustion; direct fired furnace; scale reduction; radiant tubeIndustrial furnaces for the reheating of semi-finished metal products are often direct fired with natural gas and air. Oxidation of the metals exposed to the furnace atmosphere causes significant material losses and additional work during furnace operation and in further processing. A reheating conc...
24 Explaining the "three inch rule": why model flares don't match full-scale2022It was Pohl and co-workers who discovered the so-called "Three Inch Rule" in their work on flares in the 1980s. They found that model flares with pipe diameter less than three inches do not have the same Combustion Efficiency (CE) and stability behaviour as full-scale flares, at least when wind is n...
