The effect of solvent recovery system, half by design, half by on-site installation and commissioning. With the same configuration, the takeover mode, slope direction, sealing treatment and control parameter setting are slightly different, and the recovery amount and stability after commissioning can be slightly different. The problem to be solved by on-site service is to accurately drop the intention on the drawing to the site and adjust the parameters to match the actual air source during the debugging phase, instead of installing the equipment and leaving.
Before entering the site, several things should be confirmed: whether the bearing and drainage of the foundation and the ground are in place, whether there is operation and maintenance space after the equipment is in place, whether the power supply capacity and grounding are satisfied, and whether the contact position and pipe diameter of the collection pipe network are consistent with the site. One of these items did not meet the requirements of the drawings and will be reworked after entering the site, which will not only delay the construction period but also affect the quality.
The installation process focuses on pipeline docking, electrical wiring and sealing treatment. The slope direction and low point drainage of the pipeline shall be implemented according to the design to avoid condensate accumulation. The debugging process is divided into two steps: no-load and on-load: no-load check whether the equipment operation, interlocking and alarm are normal; After loading, adjust the condensation temperature, circulating gas volume and operation mode according to the actual air source, so that the system can operate stably under real working conditions.
| Comparison item | Self-installed on site | Supporting professional installation and commissioning |
|---|---|---|
| Pipe butt joint | Construction according to experience, easy to ignore the slope | Implement slope direction and low point drainage as per design |
| Parameter tuning | Run by default | Set and record as per actual air source |
| Interlock verification | Often omitted. | Verify protection action item by item |
| Delivery Data | Scattered records | Complete installation and commissioning data and operation documents |
The deliverables include installation records, commissioning data, operation and maintenance documentation, and job training. In the acceptance process, it is suggested to check the design objectives with actual operation data, such as recovery amount, export concentration and operation stability, and compare the debugging data with the design value together, and the achievement situation is well documented. After putting into operation, arrange a return visit, review the effect with the operation data, and close the remaining problems.
Depending on the system scale and site conditions, the site installation and commissioning of a single skid-mounted device can usually be completed within a short period of time, and the specific schedule shall be determined in combination with the site operating conditions.
It is necessary to provide the actual gas source working condition and operation period to facilitate the on-load commissioning to set the parameters according to the real conditions; at the same time, arrange the post personnel to participate in the training and recording.
First, check which ring the deviation occurs with the operating data, and then check step by step according to the collection, condensation and membrane sections. The installation or parameter adjustment can be solved.
