Compared to gas stations, the tertiary vapor recovery system in oil depots represents an application of a different magnitude: featuring large tank capacities, frequent receiving and dispatching operations, and a wide variety of media, it demands higher processing capabilities and component adaptability. Understanding the characteristics of the oil depot scenario is a prerequisite for configuring appropriate equipment.
Three major differences between oil depots and gas stations
- Load level: The oil depot has a large single-time receiving and dispatching volume, with peak gas volume far exceeding that of a single station;
- Medium span: Multiple varieties are often stored in the same storage area, with a wide range of components;
- Operational rhythm: The railway, water transportation, and pipeline transportation feed are combined with tanker delivery, resulting in a complex load structure.
Configuration characteristics of oil depot equipment
- The processing capacity is calculated based on the peak transmission and reception, and is usually arranged in a high-throughput skid-mounted or split-type configuration;
- The number of condensation stages increases, adapting to the sequential liquefaction of different components;
- Increase the membrane module flux, and consider the impact of component span on separation performance;
- Recover the liquid from the separation tank and reuse it according to the type of medium.
Configuration comparison reference
| Comparison item | Gas station | oil depot |
|---|---|---|
| Peak air volume | Operational volume level of a single tanker | Multi-channel transceiver superposition level |
| Medium type | Primarily gasoline and diesel | "Multiple varieties coexist" |
| Device type | Skid-mounted integration | Skid-mounted or split-type |
| Recycled liquid management | Single aggregation | Sort cans by variety |
Suggestions for the owner of the oil depot
For oil depot projects, it is recommended to conduct process accounting based on actual measured data of receipt and dispatch, and then determine the scale and layout of the facilities. For depot areas with a variety of media and frequent renovations and expansions, it is advisable to choose a scalable modular design, allowing for the addition of condensation stages or membrane components in the later stages without altering the main structure.
Can the oil depot facilities be constructed in phases?
可以。按当前负荷先上一期，预留接口与场地，后续按吞吐增长扩建。
Will multiple types of media contaminate the recovery liquid with each other?
The design of separate condensation and tank collection can minimize cross-influence, and the specifics are calculated based on the medium list.
