The leakage points of the crane tube are concentrated in the sealing ring of the quick connector, the gas phase pipeline joint and the low point liquid accumulation, and the sealing surface of the rotating joint. The inspection process consists of three steps: checking the wear of the sealing ring, accumulation of liquid in the gas phase tube, and leakage of the rotating joint; using pressure maintenance or infrared imaging to detect VOCs leakage; regularly replacing the aging and wear of the sealing ring is more cost-effective than repairing it.
2026-11-07Selection is not about choosing a membrane, but about calculating three accounts based on the medium, gas volume, and concentration: the medium account determines the membrane area and pretreatment, the recovery account determines the upper limit of input, and the operation account determines the annual consumption and lifespan. The key to membrane component management lies in the ledger: recording the date of use, flux trend, cleaning records, and replacement nodes, and using trends instead of years to determine the lifespan.
2026-11-07The organic vapor recovery membrane is suitable for use as a transitional unit in the medium concentration range: for high concentrations, the main amount is recovered by condensation first, for medium concentrations, the membrane is used for concentration and enrichment, and for low concentrations, adsorption is used for closure. It is arranged in sections according to the concentration span.
2026-11-06The majority of electricity consumption is in the compressor and refrigeration system. To reduce consumption, five steps are taken: variable frequency speed regulation, reasonable setting of condensation temperature, optimization of adsorption regeneration, smoothing of fluctuations in buffer tanks, and sealing of collection ends, to avoid idling and frequent start stop.
2026-11-06Membrane cleaning should first diagnose the type of pollution before selecting a method: for mild loose pollution, physical cleaning such as backwashing gas wiping should be used; for moderate to severe stubborn pollution, chemical cleaning such as acid, alkali, and oxidant should be used. After cleaning, retest the flux and pressure difference. If the recovery amplitude decreases, follow the replacement plan.
2026-11-06Remote monitoring is set up in three steps: collecting parameters, setting alarm thresholds, and configuring linkage disposal; The core parameters include oil and gas concentration, temperature, pressure, vacuum degree, and adsorbent saturation. The threshold is determined based on the nameplate and historical curve, and an automatic alarm is triggered and linked when the threshold is exceeded.
2026-11-05Frosting and blockage on the low-temperature heat exchange surface should be treated in four steps: temperature control zone, tube humidity, defrosting cycle, and inspection of the blockage location; When the moisture content is high, the front dehumidification and cooling area should have a defrosting cycle determined according to the working conditions, and differential cleaning should be carried out on the separator and discharge port.
2026-11-05Installation and debugging are carried out in five steps: acceptance upon arrival, installation of piping, pre-treatment and joint debugging, airtightness and vacuum, and operation with gas; Check the piping to prevent misconnection, perform airtight vacuum leak detection, and gradually increase to the design range starting from low pressure and small load.
2026-11-05Daily inspections are divided into three layers based on days, weeks, and months: checking the meter, listening to sounds and smells, checking for leaks, cleaning and sealing the filter element every week, and measuring efficiency and tightening the interface every month. This article explains the checklist and key points of the three-layer inspections.
2026-11-04The buffer tank is used for peak shaving and valley filling, and the pulse exhaust for loading and refueling is flattened to protect the stable operation of the rear condensation adsorption membrane process. This article explains the configuration logic and capacity verification.
