HDS Pre Commission Chemical Clean
ProDecon® received an urgent enquiry from a UK oil refinery regarding a pre-commission chemical clean on their newly built Hydro-Desulphuriser due to failure of incumbent contractor. The work scope included:
SMR boiler including:
Make Gas Boiler
Flu Gas Boiler
SMR compressor pipework
HDS Compressor pipework
HDS steam generator and
SRU boiler and associated pipework.
Oxygen line from burner to filter and filter to battery limit including N2 blow dry.
These are critical systems and cleaning to the highest standard allows for a safe and rapid start-up, supports vendor warranties and prolongs plant running time. Contaminants within the boiler/steam system can damage turbines and compressors. Recognition of oxygen’s reactivity demands stringent requirements for the cleanliness of equipment in oxygen service to avoid violent reactions.
ProDecon® pre-engineered individual chemical cleaning processes for each critical system taking into account temperature, pressure and flow rate requirements to meet targeted results based on system service. Materials of construction and manufacturer’s specifications were considered in chemical process selection.
ProDecon® provided all temporary piping and circulation pumps minimising the demand on the client. Quality control and monitoring was key to achieving acceptance criteria parameters for each process. Using on site chemical analysis ProDecon® monitored the control parameters to ensure system integrity and the success of the chemical cleaning.
All chemical effluent was handled by ProDecon® providing a full turnkey chemical cleaning service.
