Harmattan Stabilizer Upgrades

In response to multiple heat exchanger failures and persistent fouling issues in a 1960's vintage condensate stabilizer at a midstream sour gas plant, our team undertook a comprehensive approach to address these challenges:

• Conducted a thorough assessment of various heat exchanger technologies to determine the most suitable option for the high fouling service.
• Utilized advanced 3D laser scanning technology to capture precise data of the congested facility area that required upgrades, ensuring accuracy in design.
• Identified decommissioned equipment that needed removal to create space for the new equipment.
• Seamlessly integrated the new design into the 3D laser scan model, allowing for detailed reviews with operations and construction teams to resolve clashes and ensure a conflict-free design before construction commenced.
• Provided construction support to tackle on-site challenges as they arose, particularly in cases where underground infrastructure was inadequately documented on existing drawings.

The project yielded impressive outcomes:

• A design that garnered full support from all client stakeholders, fostering effective collaboration and commitment to project success.
• The implementation of carefully chosen heat exchangers designed to prolong equipment lifespan and minimize cleaning requirements.
• Adoption of dual 100% exchangers in some services to reduce downtime during maintenance.
• Successful utilization of 3D laser scanning technology, leading to reduced field and engineering time while delivering an exceptionally accurate design.
