Application using CORYS IndissPlus dynamic simulator
PFCS-EN-P
Who should attend?
This course provides a deeper understanding of the operation and the monitoring, including HSE considerations, of common processes for elimination of H2S and for sulfur recovery.
Public :
Engineers and supervisors involved in operating, troubleshooting, optimizing or revamping sour gas treatment and sulfur recovery facilities.
Level :Skilled
Prerequisite :
The trainee is required to fulfill at least one of the following criteria:
to have at least 1 year of proven experience in a technical position in a refinery,
or to be in the process of being moved to a position in operation,
or to have followed a training course orientated to introduction to the refining.
Course Content
OVERVIEW OF SULFUR REMOVAL & RECOVERY
-
Duration : 0.25 Day
Amine washing and sulfur recovery units role in refineries.
Nature, origins and compositions of the streams to be treated, ammonia content.
Determination of the sulfur balance for a typical refinery.
Environmental aspects, treatment justification.
AMINE UNITS
-
Duration : 0.75 Day
Chemical reaction between amines and H2S.
Process flow sheet and equipment review: absorption, regeneration, pumps and filtration.
Process control: pressures, temperatures, amine solution optimization, steam flowrate to regenerator optimization.
Regeneration quality: objectives, follow-up methods, and performance impacts.
Application: what you can learn from your amine analysis (routine and detailed).
SULFUR RECOVERY UNITS
-
Duration : 1 Day
Chemical reactions: required and undesired ones, thermodynamics and kinetics.
Process flow sheet: thermal stage, catalytic stage, sulfur recovery, tail gas incineration. Operating parameters and impact on sulfur yield.
Process control: H2S/SO2 ratio control, air flowrate optimization, tail gas analyzer, warming up techniques and temperature control at the converters.
