Presentation 2023-2024
RBI DATA ANALYTICS Program initiated by 2023, to maintain corrosion report,
IMPLIMANTATION OF RBI
Corrosion Control Document-CCD
A Corrosion Control Document (CCD), sometimes also known as a corrosion report, corrosion manual
Topics
What is Corrosion Control Document (CCD)
What are the responsible of CCD
CCD Components
Definitions
Recommended practices
What is CCD
It provide essential input for
Mechanical integrity
Risk-based inspection programs
And also facilities to keep track of every element of operation and
minimal shutdowns
CCD Responsibility
The document responsible for summarizing
 Unit's process description
 Corrosion circuits and includes the damage mechanisms in each circuit, as well as startup and
shutdown corrosion
Mechanisms such as fatigue cracking, brittle fracture, hydrogen embrittlement &
PASCC
These documents able to understand for avoid unexpected deterioration or damage of equipment and
materials.
CCD Components
 Unit Process description
 Operating conditions, such as shutdown or startup, that may affect certain damage
mechanisms;
 Process flow and corrosion loop diagrams
 A list of damage mechanisms and failure modes, along with information on each
 Material of constructions
 Recommendations
 Integrity operating windows (IOWs)
WHAT IS CORROSION
Corrosion is a deterioration of a material by chemical reaction with their
environment.
WHAT IS CORROSION LOOP
A collection of components grouped together for the purpose of
conducting an RBI 581 Risk Analysis
The loop represents the common process, corrosion
environment, and materials of construction, and approximately
the same rates of deterioration.
Damage Mechanisms for DHDT
Erosion and Erosion-corrosion
PASCC
CL- SCC
Ammonia bisulfide corrosion(Alkaline sour water)
Sulfidation
Corrosion Under Insulation
Oxidation
Fuel ash corrosion
HCL Corrosion
HTHA
High Temp H2/H2S corrosion
Hydrogen embrittlement
Creep and stress rupture
Wet h2s damage(Blisters/HIC/SOHIC/SSC)
Ammonia chloride corrosion
Damage mechanisms and failure modes
Integrity operating widow(IOWs)
Some useful recommended practice
API RP 571 is a recommended practice that provides information about Damage Mechanisms
Affecting Fixed Equipment in the Refining Industry
API RP 580 is a recommended practice that explains the basic elements for developing,
implementing and maintaining RBI program
API RP 581 is a recommended practice that provide quantitative RBI methods that support the
minimum guidelines presented by API RP 580
API RP 584 is a recommended practice that provides the information and guidance
on developing and implementing Integrity Operating windows
API RP 970 is a recommended practice that provides information and guidance of basic
elements for developing, implementing and maintaining CCDs for a refinery
