The membrane separation oil and gas recovery device has completed its standalone test before leaving the factory, but the real starting point for its operation lies in on-site installation and commissioning: whether the interface docking is smooth, the parameter setting is accurate, and the window for operation with gas is stable, directly determining whether the device is "stable upon delivery" or "requires repair upon operation". There is a complete process for installation and commissioning, which includes six stages from arrival inspection to operation with gas, with key points and record requirements for each stage. This article clarifies the key points according to this process, and the on-site organization of new construction and renovation projects can refer to it for implementation.
What is the purpose of arrival inspection and acceptance
The equipment arrives at the site and is unloaded after inspection: The number of boxes is verified against the packing list, and the appearance and transportation damage are inspected. The nameplates and documents of explosion-proof equipment are checked one by one. Before the skid is placed in position, the foundation elevation and embedded parts are confirmed. The lifting plan is prepared based on the equipment weight and site conditions. The unpacking inspection requires the presence of three parties - the owner, the construction party, and the supplier. The inspection records are signed and archived, and the responsibility and handling method for any damage issues are determined on the spot. Spending half a day more on the inspection process can save several weeks of subsequent disputes, so it is worth the extra time.
How to manage installation and docking
The core of installation lies in the interfaces: the process piping is connected according to the slope and direction specified in the drawings, and a temporary filter section is added between the collection pipe and the device inlet to prevent construction debris from entering the machine; electrical wiring is constructed according to explosion-proof requirements, with emphasis on the protection of flameproof surfaces and seals during construction; the grounding network is reliably connected to the device skid, and crossover points are registered one by one. After the pipeline installation is completed, a tightness test - air tightness test and pressure test - is conducted according to specifications, and the test records are archived. For concealed works, images and records are retained before sealing, so that they can be retrieved and viewed during acceptance inspection.
How to proceed with debugging
Debugging is divided into three steps: standalone commissioning - power on each pump, valve, and instrument for test run, and confirm the action and signal one by one; linkage air test - water test or air test, control logic is simulated according to the working conditions, and interlock and alarm are triggered and verified item by item; operation with gas - introduce actual oil and gas, start with low load and gradually increase, and parameter setting runs through the whole process: membrane front pressure difference, vacuum degree, condensation temperature level, switching threshold, corrected to the design range according to the actual working conditions. Operation with gas is arranged during the low peak period of operation, emergency plan is disclosed in advance, and on-site personnel are assigned to their respective positions.
How to submit the delivery materials
The delivery materials consist of three sets: as-built drawings and change records, commissioning reports and parameter setting tables, operating procedures and training records. The training covers the on-duty operators, and only those who pass the assessment can independently perform their duties. In the first month, on-site visits or follow-ups are arranged to promptly correct parameter drifts. The starting point of the warranty period, response time limits, and spare parts supply are clearly stated in the contract, and the delivery list is signed by both parties. Complete submission of materials provides a basis for subsequent maintenance and renovation.
There is another piece of experience in on-site organization: designate a fixed contact person on the owner's side for each step during the commissioning period, with suppliers, construction companies, and inspection agencies all interfacing with him. In a site with multiple interfaces, the same issue can receive three different answers from the three parties, leading to confusion in terms of progress and responsibility. The contact person receives daily progress and problem lists from all parties, compiles them in the evening, and ensures that problems raised the next day are addressed without delay.
Debugging stage checklist
| link | core movement | Record requirements |
|---|---|---|
| arrival inspection | Verification of box quantity and appearance documents | Signed and archived by three parties |
| Skid in place | Foundation elevation lifting plan | Concealed works images |
| Installation and docking | Electrical grounding jumper for pipeline | Test record archiving |
| single-machine test run | Confirm the pump valves and instruments one by one | Action signal list |
| Linked air test | Interlock alarm triggered item by item | Record the simulation in a book |
| Put into operation with gas | Gradually increase parameters under low load | The setting table serves as the operational benchmark |
Management in the first month of operation
- Record key parameters daily and compare the deviations with the set values;
- The interlocking and alarm action status should be reviewed once a week;
- Emission testing is completed and archived within the first month of operation;
- Abnormalities and drifts are recorded in a booklet, and checked item by item during follow-up visits;
- Provide rotating training for operators, covering all shifts;
- Spare parts shall be in place according to the list, and inventory records shall be established simultaneously.
Frequently Asked Questions
Should businesses be suspended during gas operation?
The access points for the renovation project are arranged during the low-traffic periods, requiring only short-term peak shaving, and most stations do not need to be closed down entirely; new projects do not have such concerns and can proceed according to the project milestones.
What should be the basis for debugging parameters?
Starting from the design and manufacturer's set values, adjustments are made based on actual measured operating conditions on site; the setting process is recorded in a table, which becomes the operational benchmark after delivery, providing a basis for subsequent adjustments that can be traced.
Can we save on water testing?
It is not recommended to skip the water test. The control logic and interlocking should be tested first in the water test, and only the operating parameters should be addressed during the gas-filled phase. If the water test is skipped, problems will be exposed in a concentrated manner during the gas-filled phase, and the window for handling these issues will be even tighter.
