IGPC Ethanol Inc. continues to be a leader in successfully integrating the best available technologies forenvironmentally-responsible and sustainable growth. IGPC now sees an opportunity to build on that record,and recover the wasted ethanol present in its process effluent. Success would see improved profits andenvironmental performance for the company. However, the recovery technology must be able to capture thedilute ethanol from this effluent at low temperature which is generally 30 degrees Celsius or less, and be able touse a minimal amount of energy to perform the separation.A promising technology to achieve these requirements is Pass-through Distillation. Sheridan College hasexpertise in this technology, making it a logical partner to collaborate with on validating the use of thetechnology for this opportunity. While the technology has demonstrated a capability of meeting thoserequirements, Sheridan College and IGPC have determined that there is technical uncertainty regarding theattainable yields of ethanol when applied specifically to IGPC's effluent. This technical risk must be mitigatedbefore IGPC can decide on the commercial implementation.This project proposes a series of trials using Sheridan College's pass-through distillation pilot unit andengaging Sheridan Chemical and Environmental Engineering Technology faculty and students to determine thepractical yields of ethanol under these real-life ethanol plant conditions. The results will inform an economicassessment by IGPC so that a decision can be made as to whether adopting this technology is the best solution.

IGPC乙醇公司继续成为成功整合最佳技术以实现负责任和可持续增长的领导者。IGPC现在看到了一个建立在这一记录基础上的机会，并回收其工艺流出物中的废弃乙醇。成功将使公司的利润和精神表现得到改善。然而，回收技术必须能够在低温（通常为30 ℃或更低）下从该流出物中捕获稀乙醇，并且能够使用最小量的能量来进行分离。谢里丹学院在这项技术方面拥有专业知识，使其成为合作的逻辑合作伙伴，以验证这项技术的使用机会。虽然该技术已经证明了满足这些要求的能力，但谢里丹学院和IGPC已经确定，当专门应用于IGPC的废水时，关于乙醇的可达到产量存在技术上的不确定性。在IGPC决定商业实施之前，必须降低这种技术风险。该项目提出了一系列试验，使用谢里丹学院的直通式蒸馏试验装置，并邀请谢里丹化学和环境工程技术学院的教师和学生来确定乙醇在这些实际乙醇工厂条件下的实际产量。结果将为IGPC的经济评估提供信息，以便决定采用该技术是否是最佳解决方案。
