Daelim Industrial is a leading EPC company in Korea. Contributed to local and Middle East proposals.
Woongjin Polysilicon use Direct Chlorination process in FBR to produce Trichlorosilane (TCS) which is then fed to Siemens CVD Reactors for Polysilicon production. Facility also include Off-Gas Recovery (OGR), Converters and Utilities.
Highlights:
Process Simulation, Rating and Process conditions optimization of TCS & OGR distillation columns using Aspen Plus™.
Different operational scenarios for distillation column operation were examined for reduced energy consumption and higher product purity using Aspen Plus. Varying feed compositions were used to develop optimum set of operating conditions.
Developed rating simulation for OGR system for capacity enhancement. All columns, exchangers, pipes, pumps and instruments were rated against increased feed load. Equipment causing bottlenecking were identified.
CVD reactor operating conditions optimization for improved yield and energy efficiency.
Equilibrium calculations for CVD reactor & STC converter by minimization of Gibbs Free Energy.
Team member for process development for production of granular Polysilicon from monosilane using FBR.
Pinch analysis and heat integration of heat exchanger network using Aspen Energy Analyzer.
Intelligent Process System (IPS) Laboratory is working under the supervision of Prof. Han Chonghun (Sc.D. MIT, USA). It focuses on Process Design, Simulation & Optimization, Process Monitoring & Fault Diagnostic, and Carbon Capture & Storage. IPS Lab works in close collaboration with industries.
I worked with following companies for their projects with IPS Lab:
For Woongjin Polysilicon Co. Ltd:
Worked with Woongjin Polysilicon during design and construction phase. Developed simulation model for purification and recovery distillation trains and analyze the design at various load conditions using Aspen Plus™.
For OCI Chemicals:
Developed simulation model for OCI BTX facility using Aspen Plus™. Worked in close collaboration with OCI to ensure that model is representing actual operational data. Simulation included use of custom binary interaction parameters for solvent (Sulfolane) in extractive distillation column.
For Korea Gas Corporation (KOGAS):
A dynamic simulation of LNG unloading and storage terminal was developed using Aspen Hysys™. Effect of temperature and pressure variations on the transport properties of LNG was studied.
Worked as Process Engineer for Utilities facilities. PakArab Fertilizers consists of Ammonia, Urea, Nitro phosphate, Calcium Ammonium Nitrate, Nitric Acid and Utilities plants. It provides rich experience in all unit operations of chemical industry.
Highlights:
Process monitoring and optimization of Utilities facilities (27 MW Steam Turbine Power Plant, Steam Generation, Cooling Water, Instrument Air, Wastewater Treatment, DI water).
Process lead for rehabilitation of cooling tower and new GE water treatment program.
Process lead for installation of new dehydration unit for instrument air.
Catalyst replacement of Hydrotreater at Ammonia Plant.
Seoul National University is ranked 47th in overall world universities in 2009; 27th in Engineering. I was in Intelligent Process Systems Lab. Graduation Thesis: Process Modeling of Aromatics Recovery from Hydrocarbon Mixture using Extractive Distillation.
Received Honor`s Degree. Received Merit Scholarship. Graduation Thesis: Process Design for the Manufacture of Isoprene.
