# TAYRAŞ Advances Sustainable Base Oil Production with Rockwell Automation

> TAYRAŞ, Turkey's pioneer in re-refining used lubricating oil (ULO) into circular Group II and Group II+ base oils, has established continuous process control, plant-wide visibility, and zero unscheduled downtime across its operations in partnership with Rockwell Automation. Supported by continuous process optimization, the refinery expanded its annual ULO treatment capacity by 25% to 75,000 tons, lifting base oil production to 52,000 tons.

## Content

Addressing accelerating industrial circularity and decarbonization mandates, TAYRAŞ converts hazardous waste oils into high-performance industrial feedstocks, significantly reducing the carbon footprint associated with virgin crude-based base oil refining. To manage the thermal and hydraulic stability of its proprietary four-stage distillation and advanced hydro-processing units, TAYRAŞ deployed an integrated automation and asset management architecture with Rockwell Automation.

### Four Consecutive Years of Zero Critical Unplanned Downtime

The digital transformation and lifecycle framework deployed across the refinery comprises:

- **Integrated DCS/SCADA Architecture:** Centered on Allen-Bradley® ControlLogix® processors and FactoryTalk® View Site Edition Server architectures for centralized operational governance.
- **Process Historian & Analytics:** FactoryTalk® Historian infrastructure connects process units with tank farm facilities, enabling real-time diagnostics and data transparency.
- **Modernization & 5-Year Lifecycle Support:** Backed by TechConnect℠ technical assistance, preventative health checks, and on-site engineering, the refinery upgraded redundant HMI servers and expanded ViewPoint web-enabled visibility.
- **Operational Stability:** Operating continuously 24/7/365, the facility completed four full years of operations without experiencing a single critical or automation-induced unplanned downtime event.

### Measurable Throughput and Capacity Expansion

Targeted digital optimizations yielded major capacity milestones:

- **ULO Processing Capacity:** Increased by **25%**, scaling from 60,000 tons to **75,000 tons annually**.
- **Base Oil Output:** Increased by **over 15%**, expanding from 45,000 tons to **52,000 tons annually**.

### Executive Statements

**Ertuğrul Kılıç, Refinery Manager at TAYRAŞ:**

> “TAYRAŞ’s re-refining operations rely on advanced distillation and hydro-finishing units. Operational safety, uptime, and product consistency are extraordinarily sensitive to process control dynamics. Therefore, an automation backbone providing high availability and process stability is vital. The Rockwell Automation architecture installed across our site provides the exacting operational reliability essential to our operations.”
