The manufacturing cost must be low
The only way to liquefy is with pure cooling technology. Technologies such as pressurization, adsorption, catalysts, and membranes cannot reduce the manufacturing cost.
It must be operated automatically 24 hours a day, 365 days.
It is not applicable to the field to manually operate the device at the time of vapor inflow.
Even if a small amount of vapor is introduced at a low pressure or a small amount of vapor is introduced, it must be liquefied by more than 95%.
A method that operates only when a tank truck is unloading cannot handle vapor from Stage 2 or ground tanks.
The minimum liquefaction recovery performance should be 0.13% or more when loading stage 1.
If stage 2 is equipped, 0.18% or more can be recovered.
Electricity usage should be within 5KW or 8KW per hour.
Electricity usage is closely related to profitability.
Electric devices such as control boxes and totalizing flow meters require explosion-proof certification.
It is natural to apply explosion-proof certified products to Zone 20 hazardous areas.
The vapor should be automatically processed and the liquefaction chamber should not be heated.
The vapor should not occur or accumulate, and no separate heating method should be applied.
Heating the chamber that liquefies the vapor is inefficient and not safe.
The oil-water separation should be automatically processed and it is not recommended to use a separate filter.
Water and gasoline can be automatically separated by specific gravity. Filters are not desirable because they are consumables and increase maintenance costs.
A temporary storage tank of at least 99 liters must be provided.
If the device and the underground storage tank are not directly connected, a temporary tank with sufficient capacity to store gasoline is required so that the gasoline discharge cycle can be applied for more than one day.
The product's service life must be guaranteed to be at least 10 years.
Since the liquefaction recovery device is a facility that recovers investment costs over a long period of time, a sufficient service life must be guaranteed.
