Bioethylene Production: Impurities Don't Hinder Polymer-Grade Output, But Storage Capacity Dictates Capital Costs

ChemBioEng Reviews · 2017

Key Findings

01Impurities in bioethanol feed do not significantly affect the quality of polymer-grade bioethylene.
02The capacity of the ethylene storage tank is a significant factor influencing the capital costs of the bioethylene plant.

Application

Design takeaway

Prioritize feedstock flexibility for bioethanol and conduct thorough cost-benefit analysis for ethylene storage capacity to optimize capital expenditure in bioethylene production facilities.

How to apply

When designing a bioethylene production process, conduct sensitivity analyses on feedstock purity and storage tank size to identify the most cost-effective design parameters.

Project actions

01When researching materials for a sustainable product, consider if minor impurities in the raw material affect the final product's performance.
02When estimating costs for a design project, identify which components have the largest impact on capital expenditure and explore alternatives.

Method & Evidence

AimTo evaluate the techno-economic feasibility of producing bioethylene from bioethanol, considering the impact of feedstock quality and process design choices on cost and output.

MethodTechno-economic analysis using process simulation software (Aspen Plus and Aspen Process Economic Analyzer).

ProcedureThe study involved reviewing existing bioethanol and bioethylene production methods, defining process specifications, and then simulating a bioethylene plant. Different qualities of bioethanol were analyzed, and the impact of ethylene storage tank capacity on capital costs was assessed.

ContextChemical commodity production, sustainable manufacturing, biofuel industry.

Variables

IV["Impurities in bioethanol feed","Capacity of the ethylene storage tank"]

DV["Quality of produced bioethylene","Capital costs of the process"]

CV["Bioethylene production process parameters","Economic analysis model"]

Strengths & Limitations

Strengths

+Utilizes established process simulation software for techno-economic analysis.
+Considers the practical aspect of feedstock quality in industrial chemical production.

Limitations

The simulation might not capture all real-world complexities of handling impure feedstocks or the long-term effects of storage.

Reliability & validity

The study's reliability stems from using industry-standard simulation tools. Validity is supported by the techno-economic evaluation framework, though real-world validation would require pilot or industrial-scale data.

Think critically

How might the 'subsidiaries' mentioned for existing plants affect the economic viability of bioethylene production from 1st generation bioethanol, and how could this be mitigated in future designs?

Design Principles

"Optimize resource utilization by accepting a broader range of feedstock quality when it does not compromise final product specifications, while meticulously managing capital-intensive infrastructure components."

This insight is crucial for designers and engineers developing sustainable chemical production processes. It suggests flexibility in feedstock sourcing for bioethylene, potentially utilizing less refined bioethanol. However, it also highlights a critical design decision point regarding storage infrastructure, which can disproportionately influence project economics.

What This Means for Your Design

You can use less pure bioethanol to make bioethylene for plastics without a problem, but making the storage tank bigger costs a lot more money.

How to use in your project

1.Reference this study when discussing the trade-offs between material purity and cost in a sustainable design project.
2.Use the findings to justify decisions about the scale of storage or processing units in your design, linking it to economic viability.
