Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and labor-intensive construction of ethanol plants from scratch hinder the widespread adoption of ethanol-producing technology due to the need for on-site fabrication, plumbing, and construction.
Innovation Solution
A modular ethanol production plant composed of identically sized modules, including fermentation, distillation, and ground grain modules, pre-built and pre-wired in a factory, allowing for easy assembly and minimal on-site labor, with each module resembling a shipping container for portability and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If ethanol plants are built from scratch on site with traditional construction methods, then the plant can be constructed with custom-designed components, but the construction cost and labor requirements greatly increase
Solution Approach 1:
The ethanol production plant is divided into multiple modular units, each containing specific equipment and functionality (e.g., fermentation tanks, distillation columns, grain handling). These modules are manufactured separately in controlled factory environments and then assembled on-site, reducing construction complexity while maintaining manufacturing quality.
Solution Approach 2:
Equipment and modules are pre-assembled, pre-wired, and pre-plumbed in factory settings before delivery to the construction site. This preliminary preparation significantly reduces on-site labor requirements and construction time, directly addressing the contradiction between ease of construction and construction complexity.
2Productivity
If traditional on-site fabrication and construction methods are used, then custom plant design is achieved, but the rate at which ethanol producing technology can be put to widespread use slows down
Solution Approach 1:
By segmenting the plant into standardized modules that can be manufactured simultaneously in factories, the deployment process is accelerated. Multiple modules can be prepared in parallel and then quickly assembled on-site, dramatically increasing the deployment rate compared to traditional sequential construction methods.
Solution Approach 2:
All critical assembly, wiring, and plumbing work is performed in advance during module manufacturing. This eliminates time-consuming on-site fabrication and allows for rapid installation and commissioning, directly reducing construction time and enabling faster widespread adoption of ethanol production technology.
3Ease of manufacture
If large amounts of labor are required for fabrication, plumbing, and wiring on site, then custom installation can be performed, but construction costs greatly increase
Solution Approach 1:
All labor-intensive tasks including fabrication, plumbing, and wiring are completed during factory assembly of the modules. This transfers the labor requirement from the high-cost on-site construction phase to the lower-cost factory manufacturing phase, significantly reducing overall construction costs while maintaining installation quality.
Solution Approach 2:
Dividing the plant into pre-assembled modules concentrates the labor requirements into controlled factory environments where work can be performed more efficiently and at lower cost. On-site installation requires minimal labor, primarily for module placement and connection, directly addressing the contradiction between construction cost and labor requirement.

AI summary
The present invention provides a modular ethanol production plant constructed of a number of identically sized modules each having a supporting structure main framework to which the components contained in the modules are attached. The plurality of modules includes a fermentation module, a distillation module, a ground grain module, and an optional heating module. Each of the modules are sized to occupy the same approximate space as a standard sized ocean going shipping container. Also, each of the modules has a central walkway including piping and electrical control boxes that are aligned for each connection to the next adjacent module.
