The Abu Dhabi Department of Energy (DoE) has successfully completed its Safety in Heat campaign, aimed at ensuring compliance with the summer midday work ban for all companies operating in the energy sector.

This regulation, which prohibits outdoor work under direct sunlight from 12:30 pm to 3:00 pm, was in effect from 15 June to 15 September 2024, enhancing worker safety during the hottest months.

Throughout the campaign, the DoE’s Health, Safety, and Environment (HSE) Department conducted numerous inspection visits to sites in Abu Dhabi and Al Ain.

These inspections focused on educating workers, employers, and supervisors on the importance of adhering to the work ban and implementing best practices to minimise heat stress risks. As part of these efforts, companies were encouraged to provide shaded rest areas, fans, ample water, hydration salts, and essential first-aid equipment.

Engineer Abdul Rahman Al Alawi, Director of the HSE Department, underscored the importance of the campaign, noting that it not only reinforced adherence to safety standards but also highlighted essential measures to protect workers from heat-related illnesses. Al Alawi praised the cooperation from various entities and thanked teams involved in promoting worker safety, recognising the campaign’s role in fostering a safe work environment.

The DoE’s campaign included 2,139 internal workshops and 5,056 awareness sessions, reaching approximately 37,759 workers across the sector. Over 7,276 informational brochures were distributed, while social media platforms, videos, text messages, and emails helped deliver more than 3,800 safety messages, benefiting a total of 40,828 workers. Furthermore, 3,943 inspection visits were carried out, verifying compliance with established safety standards.

CS Combustion Solutions recently enhanced the capacity and efficiency of a sulfuric acid production plant located in Africa’s Copperbelt region, where demand for sulfuric acid is crucial in mining applications such as leaching copper and cobalt

Faced with growing demand, the plant needed to increase production while reducing operational costs and improving reliability. Through targeted improvements, CS increased daily production from 2,200 to 3,000 tons and optimised the plant’s overall performance.

Challenges before optimisation

Prior to the upgrade, the plant faced several challenges, including incomplete combustion, which led to sulfur droplets fouling downstream equipment like the waste heat boiler (WHB) and catalyst beds, increasing system pressure and requiring frequent shutdowns for maintenance. Clogging issues with conventional pressure atomisers resulted in frequent, costly nozzle replacements, while poor droplet atomisation caused hotspots in the refractory lining, increasing wear and reducing reliability.

Key measures implemented

CS Combustion Solutions tackled these issues with the following measures:
1. Ultrasonic atomisation: Replacing pressure atomisers with ultrasonic nozzles reduced droplet size from 400 to 110 µm, which minimised fouling, improved combustion, and protected the refractory lining from localised heat.
2. Swirl bodies: Introducing swirl bodies created rotational motion in the combustion air, enhancing flame formation and leading to more efficient sulfur combustion.
3. VectorWall installation: Replacing the plant’s original baffle walls with a VectorWall improved mixing within the combustion chamber, reduced hotspots, and prevented unreacted sulfur carryover to downstream components.
4. CFD analysis: A Computational Fluid Dynamics (CFD) study simulated and optimized the modifications prior to implementation, ensuring targeted performance improvements.

Results and benefits

With these enhancements, the plant boosted production capacity by 30%, enabling 40 tons of sulfur incineration per hour. The new configuration allows maintenance of sulfur guns without stopping operations, reducing downtime and saving US$160,000 annually by decreasing pressure drop. Additionally, precise ultrasonic atomisation prevented sulfur buildup on the refractory, extending its lifespan.

This case study highlights the importance of innovative combustion technologies and detailed pre-implementation analysis, offering valuable insights for facilities facing similar challenges in optimising sulfuric acid production.

Training

Dubai Electricity and Water Authority (DEWA) conducted 61 training courses and awareness sessions on occupational health and safety in the first half of 2024.

These sessions saw the participation of 2,110 employees from various departments. This initiative is part of DEWA's ongoing efforts to enhance its employees' knowledge and skills in occupational health and safety.

Trainings throughout the year

“We are dedicated to effectively implementing quality, health, safety, and environmental management systems according to the highest international standards. We strive to cultivate a culture of occupational safety and health among all employees, enabling them to keep pace with the latest developments in this field. This is part of our responsibility towards our employees, customers, and the employees of suppliers and contractors who work on DEWA’s projects. Additionally, we are committed to providing our services according to the highest standards of quality, efficiency, availability, and reliability,” said HE Saeed Mohammed Al Tayer, CEO of DEWA.

“We offer the best training and awareness programmes to enhance the safe work environment and raise health and safety standards across all DEWA’s projects and operations. This contributes to achieving employees’ happiness and enhances productivity and quality,” said Dr. Yousef Al Akraf, executive vice president of business support and human resources at DEWA.

In addition to the training courses, DEWA organises many events and awareness activities throughout the year. These include Public Health and Safety Week, Internal Health and Safety Week, Contractor Health and Safety Awareness Day, and other activities and events aimed at improving the health and safety systems of human resources. Employees who complete the training provided by DEWA staff are awarded certificates in occupational health and safety.
