FEED & Detailed Engineering Support Services For Instrument Air Package

The client’s utility consumption survey revealed a shortfall in instrumentation air capacity. They aimed to install a new instrument air compressor and auxiliary equipment to address this. Additionally, they recognized the need to optimize the compressor’s capacity, particularly in relation to the desiccant dryer’s regeneration requirements, through comprehensive Front-End Engineering & Design (FEED) and detailed engineering for plant instrument air systems.
