Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas scrubbers require constant human intervention for effective operation, leading to potential environmental hazards and inefficiencies due to overflow, spillage, and uncontrolled burning of flammable liquids, especially in remote locations.
Innovation Solution
An automated vapor and liquid separator system with a programmable logic controller (PLC) and solenoid valve that automatically regulates liquid levels and releases unwanted contaminants, using sensors and timed intervals to maintain optimal operation without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual monitoring and emptying of the scrubber is used, then operational control is maintained, but human intervention is required constantly leading to potential environmental hazards and inefficiencies
Solution Approach 1:
The scrubber system automatically monitors its own liquid level and activates the pump when liquid accumulates to a predetermined level, eliminating the need for constant human intervention while maintaining effective operation
Solution Approach 2:
A sensor continuously monitors the liquid level in the scrubber and provides feedback to the control system, which automatically activates the pump when the liquid level reaches a threshold, creating a closed-loop control system
2Productivity
If the scrubber vessel is emptied at regular intervals, then liquid level is maintained for effective separation, but frequent manual emptying is required especially in remote locations
Solution Approach 1:
The system proactively monitors liquid level and activates the pump before the liquid reaches a level that would compromise separation effectiveness, preventing the need for emergency manual intervention
Solution Approach 2:
The automated system ensures continuous monitoring and periodic pumping to maintain optimal liquid level, eliminating gaps in operation that would occur with manual intervention schedules
3Device complexity
If the scrubber is allowed to accumulate liquid, then fewer pumping operations are needed, but the liquid level may rise to the separator level compromising separation effectiveness
Solution Approach 1:
The sensor continuously monitors liquid level and provides real-time feedback to the control system, which activates the pump when liquid reaches a threshold level, ensuring separation effectiveness is maintained without over-pumping
4Object-affected harmful factors
If manual emptying of the scrubber is used, then system simplicity is maintained, but overflow and spillage of flammable liquids may occur creating environmental hazards
Solution Approach 1:
The system takes preliminary action by monitoring liquid level and activating the pump before overflow can occur, preventing the harmful effect of spillage and environmental contamination
Solution Approach 2:
The automated control system provides a safety buffer by continuously monitoring liquid level and activating pumping capacity before critical levels are reached, preventing hazardous overflow conditions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures safe and efficient separation of gas and liquid components, reducing environmental risks and operational costs by minimizing manual intervention, especially in remote locations.
Implementation Method 1
a separator situated at a level above the point of entry of the liquid into the vessel. The separator retains the liquid present in the vapor as the wanted gas vapor rises above the separator

AI summary
An automated system for the separation of vapor and liquid from a gas and liquid combination entering a separation vessel. A programmable logic control unit module controls a valve and is programmed for periodic release of separated liquid collected within the vessel upon achieving various conditions within the vessel or upon expiration of a pre-established time interval, with separated liquid delivered via an outlet port through a valve controlled by the programmable logic control unit to a storage tank.
