One of the most misunderstood and misused components of conductive steam tracing systems is heat transfer compound (HTC).
This work is a follow-up article to “Automate furnace controls to improve safety and energy efficiency,” which was published in the June 2014 edition of Hydrocarbon Processing.

Sulfur oxide additives are typically based on hydrotalcite or magnesium aluminate spinel-type structures. Magnesium alumina is the pickup agent present in the most effective SOx additives on the market; therefore, to optimize SOx reduction, it is critical to maximize the amount of the critical magnesium component in the fluid catalytic cracking unit (FCCU) in an efficient and cost-effective way.
It is never a good sign when a piece of equipment exhibits unsafe behaviors—such as large, unexpected vibrations, or cracks forming around instrument ports—particularly in the thermal reactor of a sulfur plant, where high-temperature gaseous streams chemically react as part of the process that produces elemental sulfur.
Industrial digitalization is changing the standards for operator training in the global process industry.
The steam cracking unit is highly energy demanding, requiring high-severity pyrolysis furnaces to break the carbon-carbon bonds, as well as high pressure for the purification of its products.
Uniform flow distribution inside process equipment is desirable for maximizing performance.
In an olefins plant, the reliability of ethylene cracking furnaces is one of the deciding factors used to indicate whether or not the plant can be operated at its design productivity.

Solvent deasphalting (SDA) is emerging as a low-cost, bottom-of-the-barrel upgrading process to recover valuable oil from short residue. This oil can either be further processed to make lube-oil-based stocks or cracked in secondary processing units.
From 2008 to date, 45 twisted tube heat exchangers and bundles have been installed at BAYERNOIL refineries in different units and services, allowing higher heat recovery and contributing to BAYERNOIL’s energy targets.
