Sample heat transfer fluids to offset carbon effects on thermal plant efficiency

Wright, C., Global Heat Transfer

The long-term viability of a plant depends on maintaining continuous output and reducing production costs.

Use computational fluid dynamic analysis to revamp fired heaters

Garg, A., Chilka, A., Furnace Improvements Services Inc.

A refinery process fired heater system consists of multiple sub-units, of which the fired heater is the most critical, as it impacts the overall efficiency of the system.

Minimize unplanned shutdowns of fired heater operations

Baukal, C., John Zink Co. LLC; Newnham, R., OnQuest Canada ULC; Johnson, B., John Zink Hamworthy Combustion

There are many potential “rules,” or guidelines, for the safe operation of process heaters.

HP Refining: Maintain plant production with temporary heat exchangers

Paes, A., Aggreko Process Services

Of all the process operations in a refinery or petrochemical plant, heating and cooling streams are perhaps the most pervasive.

Rethink specifications for fired heaters

Malhotra, K., S&B Engineers and Constructors Ltd.

Fired heaters are essential and important major pieces of equipment in a process plant.

HP Innovations

Blume, Adrienne, Hydrocarbon Processing Staff

EGC Critical Components has announced its dures brand of materials, a new family of proprietary thermoplastic polymer composites developed specifically for the manufacture of bushings, bearings and wear rings in pumps handling a wide range of liquids, including those that contain solid matter.

How Cr compounds discolor refractory brick walls of an ethylene cracking furnace

Al-Meshari, A., Saudi Basic Industriese Corp.; Maity, M., Al-Zahrani, E., SABIC Technology Centre

Unusual pink coloration was noticed on the entire refractory brick wall in the radiant section of an ethylene cracking furnace of a petrochemical plant. The problem was investigated by evaluating the ..

How caustic stress leads to failures of incinerator caustic spray nozzles

Maity, M., Al-Zahrani, E., Al-Meshari, A., SABIC Technology Centre

Frequent failures of the waste spray nozzles in incinerators result in accelerated degradation of the refractory lining, requiring unscheduled shutdowns for repairs. A study was carried out to identify the factors that contributed to the nozzle failure and to prevent the reoccurrence of similar failures in the future.

Extend heat exchanger lifecycle with hyper-duplex stainless steel

Perea, E., Sandvik Materials Technology

Intensifying performance demands in refineries, coupled with the ongoing decline in crude oil quality, require a new and improved duplex SS grade to withstand increasingly tough operating conditions. This need has led to the development of hyper-duplex stainless steels.

Improve the operation of fired heaters

Malhotra, K., S&B Engineers and Constructors Ltd.

Fired heaters or “process furnaces” are used extensively by the refining and petrochemical industries. These heat transfer units generate the much needed process energy through the combustio..
