Atmospheric Distillation Unit (ADU)

The Atmospheric Distillation Unit (ADU) is the primary and initial processing unit in a refinery, used to separate crude oil into various fractions based on their boiling points under normal atmospheric pressure.

Atmospheric Distillation Unit (ADU)

Our company is capable of supplying all equipment and materials for atmospheric distillation units from internationally certified manufacturers, meeting global standards. This includes distillation towers and their internal components, heat exchangers, condensers, separators, furnaces, pumps of all types, measuring and control devices, valves, pipes and fittings, as well as insulation and materials suitable for harsh environmental conditions. All materials undergo rigorous inspection and verification processes before delivery to ensure compliance with project requirements.


Our company also possesses advanced capabilities in executing installation and construction projects for new or additional distillation units. We install towers, heat exchangers, condensers, separators, pumps, furnaces, and all supporting equipment. We also handle piping work, including fabrication, welding, insulation, and pressure and leak testing. This work is complemented by the installation of modern control systems (DCS and PLC) and their integration with the refinery's operational systems. Furthermore, we execute civil works such as concrete foundations, steel structures, and support supports. Our company owns heavy equipment and employs specialized teams to ensure precise and timely project execution.


Our company also possesses expertise in implementing development and modernization projects for existing operational units, aiming to enhance their efficiency and improve their operational performance. This is achieved through upgrading control and monitoring systems to modern digital systems (DCS), installing intelligent monitoring systems to track performance and operation, improving heat recovery efficiency to reduce fuel consumption, installing modern safety systems, emergency shutdown systems, and fire and gas detection systems, as well as improving the thermal insulation of equipment and piping to minimize heat losses, thereby achieving energy savings and enhancing operational reliability.


Thanks to our qualified engineering and technical staff, specialized equipment, and operating systems certified to international standards such as API, ASME, and ISO, our company is capable of executing all phases of atmospheric distillation unit projects with high efficiency and guaranteed quality. Our extensive experience in oil refinery projects qualifies us to provide integrated solutions encompassing rehabilitation, maintenance, installation, commissioning, development, and operation. This makes us a reliable partner in executing and developing refinery projects in accordance with the highest performance, safety, and quality standards.


SERVICES


  1. Our company provides comprehensive and meticulous maintenance services for atmospheric distillation units and their various equipment. This includes tower maintenance through internal cleaning, replacement of damaged trays, and precise mechanical calibrations; maintenance of heat exchangers and condensers to improve their operational efficiency; maintenance of furnaces, pumps, and combustion systems; calibration of measuring and control instruments; and rapid leak repair and on-site welding. These services are performed by highly trained technical teams, ensuring continuous operation with high efficiency and minimal downtime.


  1. Our company has extensive experience in executing rehabilitation projects for older or inactive operational units. We rehabilitate distillation towers by repairing internal components, replacing trays and internal filling, treating corrosion areas, and conducting non-destructive testing to guarantee equipment safety. The rehabilitation work also includes upgrading heat exchangers and condensers, cleaning pipes, replacing gaskets, and improving heat exchange efficiency. Additionally, it encompasses rehabilitating crude oil heating furnaces, repairing burners, and adjusting combustion systems. We also refurbish piping and valve systems, replace damaged sections, and perform welding and inspection work according to international standards. Furthermore, we upgrade control systems, monitoring and measurement devices to meet modern operational requirements.


  1. Our company's services extend beyond mechanical and technical work to include commissioning, testing, and final handover. We conduct all trial operation procedures for the unit after installation or rehabilitation, including cleaning lines and equipment using chemical or mechanical washing, performing pressure and leak tests, calibrating measuring and control devices, and conducting trial runs to adjust performance and ensure results meet required operational specifications. We also train local personnel on operation and routine maintenance to guarantee continued efficient operation after handover.
