How to start selecting oil and gas recovery equipment? A complete approach from processing capacity accounting to model configuration

The first step in installing oil and gas recovery equipment at gas stations or storage and transportation links is not to compare prices, but to calculate the processing capacity clearly. The processing capacity is the anchor point for the entire selection process. If the calculation is biased, the subsequent models, tanks, and pump valve configurations will also be biased.

Calculate the amount of oil and gas production first, and then determine the processing capacity

The amount of oil and gas production mainly depends on the frequency of oil unloading, the amount of oil unloaded per operation, the type of storage, and the local temperature. The high temperature in summer leads to a significant increase in respiratory emissions, making it more reliable to calculate based on summer operating conditions. The empirical approach is to convert the emissions during peak oil unloading periods into hourly air volume, and leave a margin of 20-30% as the lower limit of equipment processing capacity.

How does the processing capacity correspond to the model

Taking the three-stage oil and gas recovery device as an example, the common processing capacity covers the range of 4-20 m ³/h, and membrane separation and compression condensation are two commonly used process routes. The daily oil unloading capacity of the small station is not large, and it can be covered by single-stage condensing or small processing units; In large stations or oil depots with dense vehicle traffic, a combination of condensation and membrane separation is often used to treat low concentration exhaust gas through membrane modules, making it easier to balance recovery rate and operating energy consumption.

How to choose between pry mounted and split type

Pry mounted equipment is assembled and wired before leaving the factory, and only needs to be positioned, connected, and powered on on-site. It is suitable for sites with tight schedules or tight construction periods; The split type layout is flexible, and the tank and the main engine can be placed separately, which is suitable for renovation projects with existing pipe galleries available.

Several things to confirm with the manufacturer before selecting a model

One is to calculate the recovery effect based on the oil and gas composition of this site, without using general data directly; The second is to confirm that the explosion-proof wiring, control cabinet protection, and on-site electrical conditions match; Thirdly, clarify the destination and discharge interface of the condensate to avoid secondary modification after operation; The fourth is to hand over the foundation load and embedded part dimensions to the civil engineering in advance, and install the equipment directly on site.

Confirm the processing capacity, process route, and installation form during the selection stage, so that the subsequent quotation comparison is comparable and the acceptance process is less complicated.
