Does the membrane oil and gas recovery device occupy a large area? How to arrange a tight gas station site

Does the membrane oil and gas recovery device occupy a large area? Direct answer: Compared to multi-stage combinations such as condensation and adsorption, membrane based devices have a more compact structure and usually do not occupy an advantage or disadvantage in terms of space. The entire machine can often be placed in a standard cabinet or pry box, which is suitable for tight environments such as gas stations; In terms of layout, it can be placed on the side of the canopy column, wall mounted near the equipment room, or on the ground. The key is to leave a distance between the maintenance channel and the explosion-proof zone. Many gas stations are worried about "not having enough space to put it" because they didn't think about the layout clearly, rather than the equipment being really large. This article explains the layout ideas for occupying land and when the site is tight.

What determines the land occupation

The land occupation of the membrane method device mainly comes from three parts: the membrane module and compressor unit body, the electrical and control cabinet, and the inlet pre-treatment and discharge port. Structurally, the membrane method is a physical separation, without the volume of large condensation boxes and adsorption tanks, and has a higher overall integration than the combination of condensation and adsorption; But the compressor and vacuum pump still need to occupy a certain amount of space and cannot be viewed as zero volume. What ultimately affects the land occupation is the configuration level: those with pre cooling and deep processing have higher integration, while those with simple membrane segments occupy less land. When selecting, the integration degree should be calculated based on the processing capacity and the site, rather than looking at the overall size before finding the site.

Common layout of gas stations

The layout space available for gas stations is limited but sufficient: on the side of the canopy column, the device is placed on the ground or wall mounted with the column, which does not occupy the passage space in the gas station area, and is the most commonly used solution; Equipment rooms or station buildings should be placed outside the side walls, utilizing existing building facades to save independent land occupation; Buried or arranged at a low level on the edge of the green belt, suitable for stations with full canopies. Regardless of the type, it is necessary to meet the two hard requirements of explosion-proof area division and maintenance access - the device cannot be simply plugged in, and there should be space for operation and maintenance around it. The position of the discharge outlet should be reserved according to regulations, and compliance and accessibility should not be sacrificed for the sake of saving space.

Choosing between tight venues

The principle of choosing when the venue is tight is to first ensure safety and accessibility, and then compress the volume: priority should be given to compact models that can be pried and installed, integrating the control cabinet and pre-processing into the main unit to reduce the occupation of discrete components; If it is possible to use wall hanging without landing, then wall hanging is necessary, but the premise of wall hanging is that the building structure can bear weight and the maintenance can be in place. For sites that are indeed facing difficulties, submit alternative layout plans for verification of their effectiveness in order to have a chance of being recognized. Do not use "can't be put down" as a reason for not making changes. The layout plan is determined during the renovation design phase, which is much more convenient than finding a location after the equipment arrives at the factory.

Checklist before deployment

Before positioning, check four things: division and spacing of explosion-proof areas, power capacity and grounding, size and direction of intake pipeline interface, and position of discharge and sampling ports. These four items are the key to later acceptance and operation, and any omission may result in rework of the layout. The arrangement on the side of the canopy columns also requires load-bearing and anti-collision of the columns, and ventilation and heat dissipation for external placement between equipment rooms. Go through the checklist during the design phase, and the on-site installation will be carried out according to the plan, without discovering conflicts on site.

Comparison of Layout Plans

Layout steps

1. Circle the available layout positions according to the explosion-proof zone;
2. Check the power grounding and pipeline interface;
3. Prioritize the use of compact pry and wall mounted solutions;
4. Reserve maintenance channels and discharge outlets;
5. Submission of alternative solutions for difficult sites;
6. During the design phase, the layout is determined without on-site positioning.

Frequently Asked Questions

Can the renovation of the old station really be put aside?

Most of them can be accommodated: Priority should be given to installing compact models with wall mounted or column side layout, occupying the originally idle space on the facade and column side; Submit alternative layout plans that are truly difficult, strive for recognition with verifiable results, and do not refuse to make changes on the grounds of not being able to accommodate them.

Is wall mounted installation safe?

Safety under compliance: The premise is that the building structure has sufficient load-bearing capacity, maintenance can be in place, and explosion-proof spacing and heat dissipation space are left around; Using wall hanging as a shortcut to save space and sacrificing distance and accessibility can actually bury hidden dangers.

When will the layout plan be finalized?

The design phase is determined, and we won't wait until we arrive on site to find a location; Advance nuclear explosion-proof zoning, power supply, interfaces, and discharge ports are implemented on site according to plan, and conflicts are most likely to be discovered during installation.
