Process Engineering Design Freon-22 Chillers Replacement Engineering Solution
Budget: $250 – $750 USD
I am studying a gas plant, which have Freon-22 chillers that are used to cooldown and reduce the temperature of export liquified butane product after it leaves storage tanks for export to ships. Now they are phasing out the Freon chillers to comply with environmental regulations. I want to engineer a solution for replacement of the chillers, I see two proposals one is to build a new propane closed loop refrigeration system to cool the butane or the second option is to use a side stream from the existing sub cooled propane product in our plant and use it to cool the butane in a heat exchanger.
an engineering report is required, covering both proposals with a focus on scientific analysis, environmental impact, financial implications, and other critical aspects with the following minimum sections expected:
1. Introduction
Provide a brief overview of the current use of Freon-22 chillers in butane cooling, the regulatory need for phasing out Freon, and the goal of this report in evaluating replacement options.
2. Literature Review
Summarize relevant literature on:
Environmental impact and regulations on Freon and refrigerants.
Alternatives to Freon-22, including propane refrigeration and sub-cooled propane systems.
Similar case studies on refrigerant replacement and freon phase out (if available).
closed loop refrigeration & heat exchanger design.
3. Problem Statement and Plan of Work
Problem Statement: Define the cooling requirement for butane export, compliance needs, and two proposed solutions: a propane closed-loop system or a side-stream sub-cooled existing propane solution.
Plan of Work:
Data Collection and Initial Assessment: Compile technical data and define performance criteria for both systems.
Technical Feasibility Study: Assess the cooling capabilities and technical requirements for both options.
Environmental Impact Assessment: Analyze potential environmental benefits and regulatory compliance for each proposal.
Engineering Design and Simulation: Develop preliminary designs and simulate performance under operational conditions.
Financial Analysis: Estimate CAPEX, OPEX, ROI, and payback period.
Safety and Risk Assessment: Identify risks, propose mitigation strategies.
Final Evaluation: Compare both systems and provide a recommendation.
4. Results and Discussion
Present findings from each milestone:
Technical Feasibility: Discuss design specifics, system capacity, and efficiency outcomes.
Environmental Impact: Compare projected emissions and compliance alignment.
Financial Analysis: Detail cost estimates, ROI, and payback comparisons.
Comparative Analysis: Evaluate the systems against each other in terms of all factors.
5. Conclusion
Summarize the key findings and recommend the most feasible system based on technical, environmental, financial, and safety considerations.
6. References
List all sources and studies cited in the report.
also hysys simulation files needs to be provided and other design files
