Project Background
Steam energy is widely used in edible oil manufacturing processes such as cooking, pressing, refining, and drying.
As a result, optimizing steam utilization can have a significant impact on operating costs and profitability.
However, during operation, high-temperature steam causes heat loss to the surrounding environment, leading to thermal energy waste, overheated equipment surfaces, and potential burn hazards for personnel.
This project focuses on the installation of EcoClad insulation jackets at an edible oil manufacturing plant, delivering energy loss reduction of up to 35%.
Client Objectives and Challenges
The plant faced multiple operational and compliance challenges:
- Environmental pressure: The need to meet strict emission standards to maintain cooperation with international partners.
- Reporting requirements: Compliance with government regulations on greenhouse gas (GHG) inventory and reporting.
- Energy costs: The need to minimize heat loss to the environment, preserve thermal energy, and optimize operating expenses.
- Workplace safety: Reducing risks of thermal burns and heat stress, ensuring a safe working environment for employees.
Solution Implemented – EcoClad Insulation Jackets
Problem Analysis
The EcoClad engineering team conducted a detailed assessment of the plant’s production process, with a particular focus on the heat exchangers and heat pump system.
- Heat exchangers operating at temperatures higher than ambient conditions released significant amounts of heat, leading to energy loss and reduced process efficiency due to unsuitable processing temperatures.
- Additional issues such as corrosion, blockage, and leakage further reduced heat exchanger performance and increased the risk of equipment failure.
- Fouling caused by impurity deposition on heat exchanger surfaces was identified as a common cause of performance degradation.
The heat pump system surfaces were found to reach temperatures of up to 120 °C, resulting in energy waste and unsafe surface conditions. Heat loss from these devices increased surface temperatures and ambient working-area temperatures, driving up air-conditioning electricity costs. In addition, minor dripping leaks created slip hazards, posing further occupational safety risks.
Optimized Solution
EcoClad proposed and implemented thermal insulation jackets for the heat exchangers and heat pump system, delivering the following benefits:
- Heat loss reduction: Stabilizes operating temperatures, conserves thermal energy, and prevents unnecessary energy waste. The solution maintains optimal operating temperatures for gas and fluid flows, improving overall system efficiency.
- Energy savings: Reduces energy consumption and heat dissipation to the surrounding environment, lowering energy costs.
- Condensation prevention: Temperature differences can cause condensation and corrosion on heat exchanger and pump surfaces. Insulation minimizes this risk.
- Reduction of secondary costs: Lowers air-conditioning electricity consumption caused by overheated working areas and improves workplace safety.
- Environmental impact reduction: Limits harmful emissions such as CO₂, SO₂, and NOx released into the environment.
- Improved production efficiency and sustainability: By reusing heat and condensate, the solution not only reduces operating costs but also supports sustainable development and minimizes environmental impact.
Results Achieved
