Konstantinos Kostakis

Interned in the Utilities Department at Aspropyrgos Hellenic Petroleum Refinery, gaining hands-on experience with P&IDs and PFDs for steam distribution network, Gas Turbines, Desalination Unit, and Cooling Tower. Monitored the daily operation of the cooling tower to ensure optimal performance and efficiency.

As a Chemical Process Engineer within the Energy & Industrial Business Unit, I am assigned to the 1750 MW Mintia Combined Cycle Power Plant project. My role focuses on:

1. Technical evaluation and follow-up of the following systems &

Equipment:

• Water Treatment Plant
• Industrial Wastewater Treatment Plant
• Condensate Polishing Plant
• Steam and Water Analysis System (SWAS)
• Various BOP Pumps including Combined Cycle Closed Cooling Pumps, Blowdown Pumps, Air Preheating Pumps for Gas Turbines

2. Develop and optimize P&IDs for Balance of Plant (BOP) systems

(Condensate Distribution System, Demineralized Water Distribution

System, Process Drains) ensuring accurate representation of

process flow, control strategies, and instrumentation layout in

alignment with project requirements and industry standards.

3. Prepare detailed system descriptions for the aforementioned

Balance of Plant (BOP) systems, including functional overviews,

operational sequences & control philosophies.

4. Perform sizing and prepare datasheets for pumps, heat exchangers,

control valves and safety valves (per ASME/API codes) to ensure

accurate and compliant system design.

5. Prepare detailed Material Requisitions.

6. Participate in HAZOP studies to identify and evaluate potential

process hazards, contributing to risk mitigation and ensuring safe

system design and operation.

7. Conducted power plant simulations using Thermoflow software

and performed hydraulic calculations with PipeFlow software.
