Tayraş will meet the hydrogen needs of Bilecik facility itself

Energy Journal - Tayraş Base Oil Refinery Inc. is planning a “Hydrogen Production and Storage Investment with the Electrolysis of Additional Water Method” within the borders of Selimiye Village, Selimiye Neighborhood, Osmaneli District, Bilecik Province. The produced and stored hydrogen will be used in the hydrotreatment process in the company’s mineral oil recovery activity.

85 MILLION LIRA WILL BE INVESTED

Within the scope of the project worth 85 million TL, hydrogen gas will be produced using 2 hydrogen production units with a capacity of 250 Nm3/hour by water electrolysis method. The hydrogen gas obtained as 500 Nm3/hour will be stored as 4000 Nm3 in 12 tube bundles under 200 Barg pressure and then used in production activities. Since the electricity consumption of hydrogen production units per unit is 1.25 MWh, the total electricity consumption will be 2.50 MWh. The cooling water required in the hydrogen production facility will be provided by the cooling tower with a capacity of 1200 m3/hour planned to be added.

COMPANY'S CURRENT ACTIVITY

Tayraş Base Oil Refinery Inc. conducts “Base Oil Production from Waste Mineral Oils and Bituminous Primer Production” activities in an area of ​​8.6 hectares within the borders of Osmaneli Organized Industrial Zone. Currently, mineral oils that have completed their lifespan are converted into base oils in different viscosity groups by undergoing certain processes. 60,000 tons/year of mineral oil is recovered at the facility. In addition, it is aimed to offer the base oils to the market as mineral oil by mixing them with additives in a blending unit to be positioned within the field where the facility is located.

HYDROGEN WILL BE USED IN HYDRO-PROCESS

The recovery of mineral oils consists of two main processes: distillation and hydrotreatment. In the hydrotreatment process, the distillation process is carried out from used machine oil by reacting hydrogen-rich gas with oil. In this direction, the distilled oil fractions are pressurized (125 bar-g/1810 psig.) and heated to 280°C (540°F) and then mixed with hydrogen gas. The hot oil and gas mixture is passed through a series of specially designed reactors. After the reactions take place here, the high-pressure gas is returned to the reactors. Additional hydrogen is added to compensate for losses. The project aims to produce the hydrogen needed in the hydrotreatment process.
