Hydrotreating Units

Hydrotreating units are essential components of modern refineries, designed to improve the quality of petroleum fractions by removing impurities such as sulfur, nitrogen, heavy metals, and polyaromatics. These units rely on hydrogen gas and specialized catalysts, operating under high-pressure and high-temperature conditions to ensure efficient and safe chemical conversion.

Hydrotreating Units

Hydrogen treatment units (HTUs) are among the most important operational units in modern refineries. They are used to remove impurities from petroleum products, such as sulfur, nitrogen, and heavy metals, converting them into clean products that meet global specifications for ultra-low sulfur fuels. These units also contribute to improving the quality of the refined products in terms of stability and performance, making them essential for meeting increasingly stringent environmental requirements. Because these units operate under harsh conditions of temperature, pressure, and hydrogen gas, they require special attention in terms of design and operation, as well as regular maintenance and continuous upgrades. This is where our company comes in. We possess the technical and engineering expertise to provide integrated solutions for these units, including rehabilitation, maintenance, commissioning, installation, development, expansion, consulting services, and training. We rehabilitate hydrogen treatment reactors by replacing internal pressure and corrosion-resistant linings and upgrading hydrogen inlet and distribution systems. We also upgrade heat exchangers and energy recovery systems to enhance operational efficiency, in addition to upgrading legacy control systems and converting them to advanced DCS and SCADA systems that provide higher accuracy in monitoring and control. We cover the installation work for new or upgraded unit projects, including the installation of reactors, heat exchangers, and mechanical equipment, and the laying of hydrogen and derivative piping networks. We also carry out the necessary civil works for concrete foundations and steel structures, as well as connecting electrical and control systems to central control rooms to ensure safe and reliable operation. We support refineries in upgrading their hydrogen processing units by introducing modern technologies to improve catalyst performance and extend their operational lifespan, and by developing heat recovery systems to reduce fuel consumption and emissions. We also offer projects to increase production capacity and improve the quality of final products in accordance with global environmental standards. We provide digital transformation solutions by connecting the unit to ERP and SCADA systems to enhance transparency and control of operations. Services: Rehabilitation and Modernization Services: Maintenance Services: Our services include mechanical maintenance of pumps, compressors, furnaces, and heat exchangers, as well as non-destructive testing (NDT) of pipes and equipment under pressure to ensure their integrity. We also provide electrical maintenance covering motors, generators, and distribution systems, and precise calibration of temperature, pressure, and flow gauges. We implement preventive maintenance programs and turnaround services that allow for thorough cleaning, inspection, and replacement of damaged parts to ensure continuous operation. Supply and Procurement Services: We supply all necessary spare parts and equipment, such as high-pressure valves, heat exchangers, corrosion-resistant liners, and gas and hydrogen treatment systems. We also supply hydrotreating catalysts from internationally certified companies to guarantee operational efficiency and product quality. Our services also include the supply of advanced measurement and control equipment and consumables related to routine maintenance. Consulting and Training Services: Our services include preparing economic and technical feasibility studies for expansion and rehabilitation projects, and providing basic and detailed engineering designs (FEED & Detailed Engineering). We also provide specialized training programs for engineers and technicians covering the safe operation and maintenance of these units, with a focus on managing the risks associated with working under high pressure and using hydrogen.
