The Vacuum Distillation Unit (VDU) is the next phase after atmospheric distillation and is used to extract heavy oil fractions under reduced pressure, allowing for their separation without thermal cracking.
Our company possesses extensive experience in managing atmospheric distillation units, from rehabilitating existing units and executing routine maintenance projects to installing and commissioning new equipment. We also provide development and expansion services tailored to refineries' needs and future plans. Our comprehensive approach, encompassing everything from engineering studies to commissioning and training, makes us a reliable partner for the oil sector in such vital projects. We are capable of rehabilitating distillation towers and addressing internal and external corrosion using advanced technologies and durable materials. This includes replacing worn trays and packing bundles. We can also upgrade outdated control systems with advanced DCS or SCADA systems, improving energy efficiency and reducing heat losses through advanced thermal insulation solutions. We can support refineries in increasing the production capacity of their ADU units by redesigning tower interiors and upgrading furnace and heating systems. Furthermore, we offer energy sustainability solutions through the implementation of heat recovery systems, reducing fuel consumption and emissions, and providing digital transformation services by integrating the unit with ERP and SCADA systems for production and inventory monitoring and data analysis.
Services:
1. Maintenance Services
We provide mechanical maintenance, including heat exchangers, furnaces, pumps, and separators, as well as electrical maintenance for motors, transformers, and distribution panels. We also offer calibration and maintenance services for measuring and control instruments, along with preventive maintenance and turnaround services, which include comprehensive cleaning, non-destructive testing (NDT), pressure testing, and welding.
2. Supply and Procurement Services
We supply all equipment required for the ADU unit, such as trays, heat exchangers, condensers, and pumps, in addition to modern measuring instruments, consumables, and original spare parts. We also provide auxiliary systems such as cooling, steam, and compressed air systems to ensure continuous and efficient operation.
3. Installation and Construction Services
We have experience in installing new distillation towers or upgraded sections of existing ones, along with civil works for concrete foundations and piping networks. We also fabricate and install pipelines for transporting crude oil and products, as well as electrical installations and connecting control systems to central control rooms.
4. Consulting and Training Services
Our services include preparing technical and economic feasibility studies for rehabilitation and expansion projects, and providing basic and detailed engineering designs (FEED & Detailed Engineering). We also provide specialized training programs for engineers and technicians covering the modern operation and maintenance of atmospheric distillation units, to ensure the sustainability of knowledge and the transfer of expertise to the refinery's staff.
