With a well-earned reputation and extensive expertise in the field of converting power plants from coal to natural gas, our customer’s goal was to design a gas power plant that will be the embodiment of the most efficient gas power plant in the Middle East. To allow the plant to achieve top-level efficiency, a decision early on in the design phase was to engineer it as a Combined Cycle Power Plant, which utilizes an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy.  

The principle of a Combined Cycle is that after completing its cycle in the first engine, the exhaust is still hot enough that a second subsequent heat engine can extract energy from the heat in the exhaust. By generating power from multiple streams of work, the overall efficiency of a given plant can be increased by 50–60%. 

Our customer put their trust in Ingersoll Rand mainly because the project required a fully integrated package of air compression devices with a high level of specification, and the experts at Ingersoll Rand have proved time and time again their expertise in the field, and impressed with a wide range of applicable products. 

The conversion project that aimed to modernize the power plant and enhance it with leading efficiency was divided into two phases. First, the air stations needed to be designed, and the customer awarded Ingersoll Rand with the task of designing the first compressed air station that would serve as a template for the additional air stations needed. After much deliberation and planning by our experts, a solution was provided. The customer was delighted not only with the compact air solution that was supplied, but also with the on-going engineering support and cooperation throughout the project. 

 

As is the case in most power plants, and such was the equirement for this combined cycle power plant, maintenance areas between the air stations need to be thoroughly respected to avoid injury and avail for easy access to crucial devices. 

Our engineers designed a customized enclosure for the entire system, which was able to house compressors, dryers, filters, pipework and the I&C control system, plus all the electronic connections with a reduced number of interfaces; the provided Instrument Air Skids measured just eleven metres long, providing a complete plug & play solution. 

Ingersoll Rand’s solution required minimal space to provide reliable compressed air to instrument and service outlets. In addition, few terminal points were required to connect the instrument air skids on-site and facilitate installation and start-up. 

Not to be ever underestimated, Ingersoll Rand also fully satisfied the customer’s requirement of comprehensive project management support throughout the entire project. Our Engineering team provided engineering design and documentation services according to the project’s complicated specifications. 

To our delight, the success of the initial air station design resulted in our experts being given with the task of designing additional compressed air package necessary for the second phase of the project.
