Good, bad and ugly process burner flames
As part of the U.S. Environmental Protection Agency’s (EPA’s) maximum achievable control technology (MACT) fired heater inspection program, the authors’ company has inspected nearly 1,000 heaters since the program started in 2015. These inspections have revealed all types of flames—the good, bad and ugly. Here, good is defined as no changes are needed; bad is defined as changes are needed where the conditions are not likely dangerous; and ugly is defined as immediate changes are needed because the conditions are potentially dangerous.

Intensification of sulfur processing units by oxygen enrichment and process flowsheet optimization
The consistent global trend toward improvements in air quality and tighter regulations on emissions, as well as the International Maritime Organization’s shipping regulations, continue to mitigate sulfur levels—not only in conventional transport fuels (petrol and diesel), but also in jet fuels, fuel oils and other heavier distillates.
Steam generator in a hydrocracker high-pressure loop—why not?
Historically, there has been a perception in the industry that it is not safe to include a steam generator in the high-pressure loop of a hydrocracker.
Flow modeling as a tool for WHRU performance optimization
Greenhouse gas (GHG) emissions have become a growing concern for many industrialized countries over the past few years.
Use CFD modeling to improve burner design and operation
Process heaters are essential pieces of equipment in the refining and petrochemical industry that are used to heat hydrocarbons to a desired temperature.
Refinery tower inspections: Discovering problems and preventing malfunctions
A previous survey identified installation mishaps to be one of the top five causes of tower malfunctions.
Water Management: Minimize white rust in galvanized cooling systems
Galvanized coatings for cooling tower systems (cooling towers, evaporator tube bundles, etc.) have been used in the industry since the 1950s due to their relatively low cost and long service life.
Cost-effective naphtha hydrotreating unit revamp to increase high-octane reformate production
India, which is the third-largest economy in the world, is home to nearly 18% of the world’s population (nearly 1.4 B).
