In December 2025, oil-based mud treatment project in Africa was successfully delivered in Africa. This solution uses the BLJ-16 thermal desorption unit to accommodate customers’ large-scale recycling volumes. This milestone marks a key step forward for the customer in upgrading their oil-based mud management solutions. This collaboration has enabled compliant on-site reduction and harmless disposal. This oil-based mud treatment project also demonstrates a practical and replicable solution applicable to the oil and gas services industry in Africa.
During the manufacturing phase, the system configuration and structural design were optimized based on the characteristics of oil-based mud. Key units, including the main reactor, discharge screw, condensation system, and exhaust gas treatment module, were all custom-manufactured and inspected at the factory. Simultaneously, critical vulnerable parts and installation-related accessories were meticulously inventoried, thereby reducing uncertainties and potential delays during overseas installation and commissioning.
Prior to shipment, all components were packaged with moisture-proof and shock-resistant measures, and clearly labeled according to installation sequence and functional grouping. Upon arrival, the project team coordinated with local port operations and the client’s site conditions to arrange customs clearance, inland transportation, and staged unloading. This phased receiving strategy optimized on-site storage, reduced handling risks, and ensured sufficient buffer time for subsequent installation activities.
Installation engineers assisted the client with site clearing, foundation formwork construction, and foundation layout marking. Then, the installation team welded the condensation platform, feeding platform, and supporting structures, ensuring readiness for major equipment positioning and lifting.
The installation team completed the hoisting of key equipment components. Engineers then installed oil-gas pipelines, flue gas pipelines, and tail gas treatment pipelines. Despite unstable power supply and changing weather conditions, engineers adjusted the installation plan to maintain overall progress.
Under on-site coordination, engineers integrated the fuel gas system, combustion air system, water system, and electrical control system into the TDU. The team installed refractory lining, insulation, and protective structures at the same time, ensuring safe and stable system operation.
System interlock commissioning, and trial operation with feedstock(15 tons oil-based mud) were carried out. The system achieved stable oil recovery and solid residue discharge. Then, engineers provided on-site training for the client’s operators, covering standard operation routine maintenance.
After multiple rounds of commissioning and optimization, the BLJ-16 TDU system achieved continuous and stable operation in the field. Its oil-based mud treatment performance met project objectives. Beston Group successfully received the project acceptance certificate. The successful delivery of this project not only solved the client’s long-standing oil-based mud disposal problem but also provided the local oil and gas service industry with a replicable, engineering-grade treatment solution.
