3 Long-term and stable operation

Long-term and stable O&M

- More than 60-year experience of O&M Control system

- On-site control system: combines distributed control system and centralized control system with integrating auto and semi-auto control systems.

- Remote operation assistance system: The real-time data of the WTE in Vietnam is remotely connected to Hitz’s headquarter (Osaka) and engineering office in Vietnam  therefore the plant can timely receive the assistance for daily operation or when facing the troubles during the operation.

- This system not only supports the plant operating stability and effectively, prevents incidents or risks but also reduces the O&M cost.

ethanation system (WTM system)

WTM System Features

• Not using dilution water means that the fermentation tank can be compact and only a small amount of

energy is required for heating.

• High temperature solubilization means improved degradation rates for solids. It also achieves a high

organic matter decomposition rate (85%).

• Using medium temperature methane fermentation, which is highly resistant to ammonia inhibition, allows it

to handle a wide range of raw garbage qualities.

This system converts solid organic waste such as raw garbage, pruned branches and paper into biogas via

methane fermentation. It does not require any modifications to the existing waste collection setup.

Features of the Hitz Kompogas System

• Can convert fermentation residue into compost as well as convert raw waste into biogas.

• The system was accredited by the Japan Waste Management Association in 2001 as a waste methane

fermentation system in line with technical inspection and verification procedures.

2. Power conversion:

Power-to-Gas (PtG) system

• Renewable energy varies by means of condition of wind and hours of daylight temporally/seasonally. While, Energy storage is required for stable use of power generated from renewable energy => “Power to gas” • Power to Gas (PtG): Renewable electricity convert to gas fuel by water electrolysis (and methanation) for

energy storage. European countries have been carried out widely spreading of PtG.

- Hydrogen generation by water electrolysis (Polymer electrolyte membrane (PEM) electrolysis): using renewable energies

- Methanation: by chemical reaction between renewable energy sourced hydrogen and CO2
