Smart designing of revamping projects
Category Chemical plant
Outline Design automation and integrated management using the smart plant program
1. Smart plant P&ID: Process design
2. Smart plant electrical: Electrical design
3. Smart plant instrument: Instrumentation design
4. Smart plant 3D: 3D modeling
5. Smart plant foundation: Design integrated management system
Key points SGC E&C minimizes design errors through computerization and interaction of all design documents.
Revamping projects for existing plants, aimed at physically expanding or improving their performance, are significantly more challenging than building new plants from scratch. SGC E&C collects information from existing plants and uses it to create 3D models, while accurately planning the scope of the new design and confirming the construction scope and material procurement through on-site verification. This process is meant to enhance the convenience of workers during the construction period and block any possible interference from the existing plant.

Smart designing of new projects
Category Chemical plant
Outline Minimize design errors by applying 3D models to all projects
Key points SGC E&C resolves problems that may arise during construction by utilizing 3D modeling to represent every design throughout the entire process in a virtual space.
Shop drawings of steel structures, expansion bellows and spring supports for large pipes and equipment are all integrated into a single 3D file in real time. This enables us to facilitate rapid and accurate collaboration and confirmation of the design between different trades, and effectively prevent errors and omissions during the construction phase.

Designing of 3D-based structural analysis of plant
Category 3D structural analysis
Outline Design structures of buildings and facilities based on 3D structural analysis
1. Incorporate information of structural components in the building and create a 3D model
2. Analyze and design for mechanical, seismic and wind loads
Key points SGC E&C ensures safety through 3D structural analysis mirroring the actual buildings and structures. We perform structural design by taking into account the load factors based on the location and site conditions of the structure being designed, as well as the characteristics of the mechanical equipment being used, and the information on the structural components being utilized.
We ensure structural safety by conducting structural force reviews that reflect all load conditions for each structural component based on a 3D analysis model. In addition, we perform simulation analysis for earthquakes and wind loads to prepare for natural disasters to ensure safety structures.

Detailed review of buildings through 3D modeling
Category BIM-based smart design
Outline Detailed review of structural components through 3D modeling of buildings and structures before construction
1. 3D modeling based on BIM (building information modeling)
2. Detailed review of each structural component and joint
3. Use of drawings for steel fabrication
Key points SGC E&C performs interference and joint reviews between structural components using BIM-based 3D modeling. We perform 3D modeling based on the information in the drawings to minimize the interference between structural components that may occur on-site.
3D modeling can prevent potential interference on-site. We review the optimal design based on the actual implementation of joint parts before the start of construction, customizing on-site variations.

CCU(Carbon Capture & Utilization)
Category Power plant
Outline
- Process design for CO₂ capture and liquefaction
- Technology that captures CO₂ emitted from power plants with high purity using an aqueous amine absorption agent
- Constructed Korea’s first large-scale commercial plant for capturing and liquefying CO₂ using KoSol-6, an aqueous amine absorption agent developed by the Korea Electric Power Research Institute
- Processing capacity: Annual production of 100,000 tons of liquid CO₂ (300 tons/day)
- CO₂ removal efficiency: > 90%
- CO₂ purity : > 99.9%
The flue gas emitted from the power plant is captured and directed to the capture facility using a boosting fan. First, SOx and dust are removed in the first desulfurization equipment, and then 90% of the CO₂ is absorbed into the amine absorption agent in the CO₂ absorber and transported to the CO₂ stripper. The remaining 10% of CO₂ is sent back to the power plant stack along with the flue gas. Third, the CO₂-absorption agent is heated with steam in the stripper to separate the CO₂, which is then sent to the liquefaction facility. The absorption agent is then regenerated and recycled back to the CO₂ absorber.
In the final liquefaction facility, the CO₂ is compressed to over 20 BarG and then undergoes primary moisture removal in the cooler and chiller, and final moisture removal in the gel dryer. After that, it is cooled to -20°C in the CO₂ purifier to produce liquid carbon dioxide, which is then transferred to storage tanks and shipped out as L-CO₂ in tank lorries.
Key points
- KEPCO wet capture technology was certified by the government.
- Commercial plant scale-up and design verification conducted using ASPEN+, and design of the desulfurization facility and tower based on design know-how
