The Vapor Recovery Units (VRU) is usually based on Adsorption-Absorption technology.
This technology is recognized worldwide as the best, most effective and
reliable technology for recovering volatile hydrocarbons arising from
the loading and storage of volatile petroleum products.

Hydrocarbons contained in organic vapor are adsorbed through activated carbon,
and the remaining air are discharged to the atmosphere.
Hydrocarbon vapor adsorbed on activated carbon is desorbed and transported
using a vacuum pump, etc., in contact with the liquid absorbent in the absorption tower.
It is recovered as a liquid product.
This integrated processes is designed to be continuous.

Hanyang Industry has cooperated with John Zink In USA, which has the
core technology of VRU, as a partner to supply VRU in our market.
