Problem No. 79 What happens in the low-pressure carbamate condenser?
In a submerged condenser, not all vapours should condense. A residual vapour phase is needed to maintain a high heat-transfer coefficient, while inert gases must also be accommodated. The following round table discussion highlights the practical challenges associated with operating an LPCC.
Retrofitting with next-generation liquid sulphur treating
Retrofitting liquid sulphur treating into existing sulphur recovery units can significantly improve safety by reducing hydrogen sulphide in sulphur storage and handling, while also lowering the risk of toxic exposure and explosions. Worley Comprimo reviews proven treating technologies and retrofit options that can be implemented with minimal disruption to existing operations.
Overcoming the complexities of liquid sulphur pipeline transport
Fluor discusses the unique challenges associated with transporting liquid sulphur through pipelines and presents key design considerations and operational strategies that enable safe, continuous and reliable long-distance operation.
Best practices in SRU steam and condensate handling
QMax Industries explains why effective steam and condensate management is essential to the performance, safety, and reliability of sulphur recovery units.
Ammonia safety update
As well as a recent US Chemical Safety Board report on an ammonia release incident, the past year has seen considerable focus on safety of ammonia at sea, in preparation for its possible use as a clean burning maritime fuel.
Techniques to extend the life of steam methane reformer tubes
Muhammad Faisal Faraz and Abdullah Al Balushi of OQBi explain how by implementing a series of technical and process improvements, OQBi has successfully extended the lifespan of its reformer tubes by six years beyond the original design life of 100,000 hours.
The pros and cons of SRU extended downtime
Wood presents the pros and cons of leaving a refinery SRU on hot standby versus long-term idle taking into consideration reliability, safety, and operations responsibilities during extended downtime.
Detecting and preventing SO2 breakthrough
Fluor discusses the main causes, detection techniques, management methods and prevention procedures of SO2 breakthrough in the quench water system of a TGTU, with some unique design features for Fluor’s Desuperheater Contact Condenser.
