Converting Hydroprocessing Equipment To Produce Renewable Diesel From Soybean And Corn Oil: Corrosion And Materials Considerations

Product Number: 51322-17989-SG

Author: Nathaniel Sutton, Ken Kirkham

Publication Date: 2022

As governments around the world seek to promote the adoption of lower-carbon fuels, credits are available for fuels which satisfy various low-carbon or renewable fuels standards. In the United States, the most common standards discussed include California’s Low Carbon Fuels Standard1 and the US EPA’s Renewable Fuel Standard2. These standards define the acceptable methods (called pathways) for conversion of renewable feeds into consumer fuel products. In order for a producer to be eligible for credits, one of the acceptable pathways must be used. The most common pathway presently being used or considered by most facilities is hydrotreating.

Corrosion Management in Hydrocracking and Hydroprocessing Units

Product Number: MPWT19-14442

Author: Hendrik J. Debruyn

Publication Date: 2019

$0.00

Hydrocracking and other refinery hydroprocessing units have a common goal to convert organic sulfur compounds to hydrogen sulfide (H2S) that can be removed, thereby producing low-sulfur refinery products. Corrosion and equipment degradation risks range from high-temperature hydrogen attacks (HTHA) to ammonium bisulfide and ammonium chloride corrosion in the downstream heat recovery and fluid separation equipment.
This paper provides an overview of corrosion management principles that can be applied to reduce operating risks in new and existing units, focusing equipment susceptible to ammonium bisulfide (NH4HS) and ammonium chloride (NH4Cl) corrosion. Best practices for materials selection, as well as designing for corrosion management through adequate provision of corrosion management related instrumentation and sampling points are covered.

Deadleg Stress Corrosion Cracking Risks in SS Piping Systems in Refining and Renewable Units

Product Number: 51324-20816-SG

Author: Cathleen Shargay; Garry Jacobs; Shahab Soltaninia

Publication Date: 2024

$40.00

Although the problem of chloride stress corrosion cracking (SCC) of austenitic stainless steel drain lines in hydroprocessing units has been well known for many years, new questions on these deadlegs are arising with the renewable units handling biofuel feeds. Some potential issues are in the hydrodeoxygenation (HDO) units and certain pretreatment units, wherever these units have high pressure SS piping. Many of the hydroprocessing unit case histories of leaks and cracks occurred shortly after startups from turnarounds and were attributed to water not being drained before startup. In contrast, some of the renewable units may have a risk of water condensing in deadlegs even during normal operation. The hydroprocessing unit case histories have been compiled to help to define the conditions, such as main line operating temperature and pressure which contribute to SCC in the deadlegs. The process chemistry, especially water content, oxygen and pH differences between the refining and renewable units are reviewed, and material recommendations are given for drain lines and other deadlegs in each type of unit.

Low H2S High Temperature Sulfur Attack in Refining Hydrotreating Processes

Product Number: 51320-14626-SG

Author: Brittany L. Oliva-Chatelain, John A. Pugh, Sudhakar Mahajanam, Fred Addington

Publication Date: 2020

$20.00

There are three known types of high temperature sulfidation present in the refining industry. Two of them have industry recognized methodologies for damage prediction, and they both manifest as general thinning morphologies. They are known as H2-free sulfidation and H2/H2S corrosion. The third type, although recognized as H2-free, low-sulfur corrosion, does not have an accepted chemical theory or a prediction tool, and it manifests as a localized thinning morphology. This third type of sulfidation is much less common and occurs in units and process conditions where little-to-no H2S would be expected to be present. This paper discusses the operating conditions in two known damage cases presented here and provides a viable chemical theory that could lead to the observed damage profile. In addition, an approach to mitigation of this attack is discussed.
