Chevron is a leading refiner and marketer of petroleum products in South Africa. The Network of Caltex service stations, one of the country’s top five petroleum brands, are supplied through its subsidiary Chevron South Africa. Its refinery which is based in Cape Town does annual shutdowns. However, this year they did the largest one that the plant has ever had. This required the supply of superior equipment and therefore Rand-Air, a supplier in portable compressed air and power generation rental was assigned to the task.
Oil-free air was critical in ensuring the success of the shutdown. “The compressed air needs to comply with strict quality requirements to prevent damage to the reactor or pollution to the catalyst. It is also essential for the airflow to be regulated correctly as the optimal regeneration speed is dependent on a small band of oxygen concentration to ensure the accurate control of temperature,” explains Cindy Ross, Sales Consultant for Rand-Air.
The shutdown which took approximately two months required vast equipment that was utilised for the smooth running of the shutdown included eleven coolers, seven clean air packages, thirteen 800cfm compressors, two 300kva generators, three 260cfm compressors, one PTS916 oil-free compressors, two PNS1250 oil-free compressors, two high pressure dryers and one 25bar offshore compressor.
Understanding the requirements of the hiring of portable compressors and generators, Rand-Air was able to accommodate the need for the units that contributed to the overall success of the shutdown. “We are proud of our participation and our long-standing relationship with Chevron highlights our dedication to delivering on exceptional customer service. With careful planning between Chevron and ourselves everything ran according to plan,” Ross concludes.
