Combined Compression Train for Ammonia Production Plant Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ammonia production plants require multiple compression trains, leading to complexity and high costs due to the need for multiple drivers and compressors, making the process inefficient and expensive.
Innovation Solution
Combining at least two compression sections into a single combined compression train driven by a single driver, with the option of using integrally geared compressors for enhanced efficiency and cost reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple compression trains are used to compress different gases (feed gas, process air, syngas, refrigerant), then each gas can be compressed to the required pressure, but the plant complexity and cost increase due to multiple drivers and compressors
Solution Approach 1:
The patent combines multiple compression trains into a single integrated compression train that can handle different gases (feed gas, process air, syngas, and refrigerant) through a unified system architecture, reducing the total number of drivers and compressors while maintaining the required compression capabilities for each gas stream
Solution Approach 2:
The compression train is designed with multi-functional compressors that can process different types of gases through different operational modes or configurations, allowing a single compression train to perform the functions previously requiring separate dedicated compression trains for each gas stream
2Productivity
If multiple drivers and compressors are deployed for different compression tasks, then all compression requirements are met, but the cost and efficiency deteriorate
Solution Approach 1:
The patent merges multiple separate compression systems into a single integrated compression train, reducing the total number of drivers and compressors required, which directly lowers capital costs and operational expenses while maintaining comprehensive compression coverage for all process streams
Solution Approach 2:
The design employs universal compressors capable of handling multiple gas types and compression tasks through a single device, eliminating the need for multiple specialized compressors and their associated drivers, thereby reducing both manufacturing costs and operational complexity
