Integrated Reflux Separator Layout for Gas Condensing Plants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas collecting plants using chemical absorption methods face challenges in controlling liquid levels and efficiency due to sloshing and boiling in reboilers, and suffer from increased space requirements and heat loss due to separate condenser and reflux apparatus configurations.
Innovation Solution
A gas condensing device with a reflux separator is integrated into a single housing, separating condensate and evaporation gas paths to prevent flow interference and facilitate re-condensation, while mounting the condenser and reflux apparatus together to reduce space and heat loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a reboiler of kettle type or thermocyphon type is used to heat absorbent liquid for regeneration, then the absorbent liquid can be heated to separate gas, but liquid level control becomes difficult due to sloshing and boiling effects
Solution Approach 1:
The reboiler is divided into a heating chamber and a separation chamber by a partition wall. The heating chamber contains the heater and handles boiling liquid, while the separation chamber receives the heated liquid through an opening in the partition wall and allows calm separation of gas and liquid phases. This segmentation prevents sloshing from affecting liquid level measurement and control.
2Ease of operation
If the condenser and reflux apparatus are mounted separately in conventional gas collecting plants, then each component can function independently, but the mounting space increases and heat loss occurs during liquid transfer
Solution Approach 1:
The condenser and reflux apparatus are integrated into a single unified structure. The condenser is positioned in the upper portion of the housing while the reflux apparatus is mounted in the lower portion, forming a compact integrated assembly. This merging reduces the overall mounting space and eliminates the need for separate installations while maintaining independent functional capabilities of each component.
3Ease of repair
If the condenser and reflux apparatus are mounted separately, then each component can be maintained independently, but heat loss occurs during absorbent liquid transfer between components
Solution Approach 1:
The condenser and reflux apparatus are integrated into a single housing structure with the reflux apparatus positioned directly below the condenser. This integration creates a compact heat transfer path where condensed liquid can be transferred with minimal exposure to ambient environment, reducing heat loss. The integrated design maintains ease of maintenance through accessible component interfaces while eliminating energy waste from extended transfer paths.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances control over liquid levels, improves gas separation efficiency, and reduces the mounting space and heat loss by integrating the condenser and reflux apparatus, allowing for efficient re-condensation of evaporation gas.
Implementation Method 1
a condenser mounted in an upper portion of the housing and configured to condense the regeneration gas
Implementation Method 2
a reflux separator configured to separate an inlet through which the condensate is supplied into the condensate chamber from an outlet through which the evaporation gas is discharged from the condensate chamber
Implementation Method 3
a reboiler for heating the absorbent liquid is mounted at the regeneration tower as energy source for regeneration. The reboiler heats the absorbent liquid up to a temperature at which the regeneration is possible so as to separate the gas contained in the absorbent liquid

AI summary
A gas condensing device may be configured to condense regeneration gas and separate target gas from condensate. The gas condensing device may include: a housing; a condenser mounted in an upper portion of the housing and configured to condense the regeneration gas; and a reflux apparatus mounted in the housing below the condenser and configured to temporarily store the condensate and discharge evaporation gas evaporated from the condensate back to the condenser.
