Introduction of Energy Saving Equipment to Brewery
- Representative Participant
- Sapporo International Inc.
Outline of GHG Mitigation Activity
Sapporo Group’s Vietnam branch (Sapporo Vietnam Limited.) introduces highly-efficient and energy-saving equipment together with the expansion of production facilities in Long An brewery. This project reduces electricity and LPG consumption by introducing air compressor, cold water chiller and once-through boiler (LPG). This project reduces the percentage of unloads as well as the frequency of starts / stops and improves the performance of each individual unit. A cascade cooling system is built by the cold water chiller.
Expected GHG Emission Reductions
111 tCO2-eq./year
Air compressor: 18.3 [tCO2/year]
= (RE electricity consumption − PJ electricity consumption) × EFel
= (Electricity required ÷ SP of current equipment × (SPRE − SPPJ)) × EFel
Cold water chiller: 13.6 [tCO2/year]
= (RE electricity consumption − PJ electricity consumption) × EFel
= (Refrigeration capacity required × (1 ÷ COPRE − 1 ÷ COPPJ)) × EFel
Once-through boiler: 79.3 [tCO2/year]
= (RE LPG consumption − PJ LPG consumption) × EFlpg
= (RE LPG consumption
− RE LPG consumption × ηRE ÷ ηPJ × ORPJ
+ RE LPG consumption × (1 − ORPJ)) × EFlpg
RE: Reference, PJ: Project,
EFel: Grid emission factor, EFlpg: LPG emission factor,
SP: Specific power of air compressor,
COP: Coefficient of performance of chiller,
η: Boiler efficiency, OR: Operation rate
