Designing process changes to reduce consumption
Cigdem developed a number of cost saving projects at a polypropylene plant. Using Piping and Instrumentation Diagrams, Cigdem collected and evaluated metered flows across units. Having reviewed current practice, Cigdem then proposed a number of maintenance and process changes to reduce the plant’s water and steam consumption.
Cigdem overcome a number of engineering challenges to produce designs for modifications to fuel gas, steam, water and nitrogen systems across the plant. Cigdem’s work results in a number significant financial savings for the company: every year, £45,000 will be saved through the improved water system, £100,000 from a new fuel gas heater, £150,000 via the steam system and £30,000 from her flare system design. In total, her savings equal £325,000 per year, with an average payback period of only four months.
“Due to the technical knowledge and drive which Cigdem has shown during her placement, the amount and type of assigned to her has far exceeded that which students normally achieve”.
