G-RECO
LIQUID RECOVERY DOWN TO THE LAST DROP THROUGH PIGGING SYSTEM
PIGGING SYSTEM FOR PRODUCT RECOVERY
G-RECO is the system developed by Granzotto for the recovery of the residual liquid product in the pipes of an industrial plant. Granzotto designs and manufactures G-RECO systems tailored to its customers, paying particular attention to the characteristics of the plant and the product to be recovered. G-RECO systems exploit the pigging technique, which involves the use of a mobile device (pig) which, by sliding inside the pipe, allows the recovery of very high percentages of the residual product.
G-RECO systems include Pig launch and arrival stations, piping, valves, PLCs and all functional components for the recovery of liquids in an industrial plant. The components are carefully selected in the design phase and the systems are designed to make integration into the main plant as simple and quick as possible.
MAIN ADVANTAGES RELATED TO THE USE OF G-RECO SYSTEMS
REDUCTION OF PRODUCT WASTE
REDUCED WASHING TIMES
REDUCTION OF THE USE OF WATER AND DETERGENTS IN THE WASHING PHASE
IMPROVEMENT OF THE CLEANING AND SANITIZATION OF THE INSTALLATIONS
REDUCTION OF PRODUCT CHANGE TIMES
IN ADDITION, THE G-RECO / PIGGING SYSTEM GUARANTEES:
The many advantages deriving from the use of G-RECO systems translate overall into an improvement in the efficiency of the production process and a reduction in costs, ultimately leading to an increase in operating margins and profits. Nonetheless, thanks to the reduction of product waste and the lower use of detergents, the use of G-RECO systems is an excellent solution for improving the environmental sustainability of the production process.
Product recovery using G-RECO systems becomes particularly convenient when:
- The permanence of product residues in the pipes generates problems (e.g. polymers)
- The product has a high ag value joint (e.g. lubricating oil, toothpaste)
- The product is highly polluting and expensive to dispose of
- High production flexibility and frequent product changes must be guaranteed
- The absence of cross-contamination of the products transferred with the same line must be guaranteed
PERFECTLY INTEGRABLE IN THE PRODUCTION PLANT
The G-RECO system is designed in collaboration with the customer and based on their needs, analysing the properties of the liquid to be recovered and the characteristics of the destination plant. A G-RECO construction project is divided into the following phases:
1. Analysis of the chemical-physical and rheological properties of the product (e.g. density, viscosity, etc.)
2. Analysis of regulatory constraints (e.g. food/chemical sector, environmental requirements, ATEX directives, etc.)
3. Analysis of the plant layout (e.g. distances, curves, obstacles, equipments, etc.)
4. Design and sizing of the G-RECO system
5. Start-up and commissioning of the G-RECO system
