Introduction
In-depth structural analysis and technical implementation suggestions
| Process type | Capture efficiency | Nodes to be improved | Suggested optimization measures |
|---|---|---|---|
| Chemical absorption method | ≥80% | Solvent degradation loss | Graded filtration system modification |
| Cryogenic liquefaction method | 95% | Cold and heat circulation | Residual pressure energy recovery device |
Key Equipment Parameter Control System
The specification clearly states that the design suggestion that the packing layer of the absorption tower should not exceed 20m layer height is based on a large amount of engineering data statistics. Taking the 2019 Shanghai Petrochemical Renovation Project as an example, after optimizing the 22m packing to 3.5m×5-stage tower section, the reboiler steam consumption was reduced by 18%.
Safety Control and Intelligent Management
- The selection standard requires the application of 68-type automatic locking device
- The execution cycle of the SDV valve group in the intrinsic safety design must be <2 seconds
A demonstration project in Shenzhen shows that after the DCS early warning mechanism is adopted for the tower top temperature, 87 operating fluctuations are avoided throughout the year, ensuring the stable operation of the system for 8097 hours/year.
Energy saving benefit verification algorithm
Qᵣ=(hₕ-h꜀)×LPT/λ Where: Qᵣ——regeneration energy consumption (MJ/t) h——steam enthalpy value (check ASME S) LPT——liquid phase compensation coefficient λ——cogeneration benefit factor
Implementation suggestion list
- Newly built adjacent thermal power unit layout channel
- Mandatory use of bimetallic composite plate gaskets
- Selection of four-wire simultaneous centering welding process
