The first Integrated Waste Management Facility (IWMF) will be built on a reclaimed island. The facility is expected to be completed by 2024 off the coast of Shek Kwu Chau and south of Lantau island, under the municipality of Hong Kong. This landmark project will be the first to reduce the municipal waste, as Hong Kong currently doesn’t have recycled landfills. In addition to recycling solid waste, the facility complex will use flue gas cleaning system which will secure that the emission produced from the plant is according to the standards of the Hong Kong and the European Union for a cleaner environment.
Keppel Seghers, a waste to energy (WTE) and infrastructure firm, along with its Chinese partner, Zhen Hu, have been awarded a contract worth $4 billion to build Hong Kong’s first integrated waste management facility. The awarded contract was successfully delivered through an international tender ‘The Environmental Protection Department’ of the Government of the Hong Kong Special Administrative Region. This department aims to develop ecological and socioeconomic awareness with releasing projects that will improve the overall quality of life in Hong Kong.
This project brought together two leading companies that will develop a world-class waste management project that is in compliance with world ecology standards. The construction phase, along with engineering and procurement, is developed and placed by Zhen Hua, which is considered to be the largest construction and reclamation companies in Hong Kong. This phase will be initiated by reclaiming an area about 16 ha large, developing the design and engineering the building process of breakwaters, and the IWMF, along with its related port facilities on the island shore.
During the construction phase, Keppel Seghers will provide its proprietary waste-to-energy technology. Additionally, they will provide a mechanical supply and treatment of the plant, power island and desalination facilities. Keppel Infrastructure Services will provide operation and maintenance services for 15 years after the building project is implemented and facility open for work.
The Keppel Seghers company has developed advanced technology when it comes to waste management. Their flue gas cleaning systems combine leveraging technology and specialists that are acquainted with implementing their machine to provide superior environmental performance. Their aim is to provide technology that helps facilities to produce minimum emissions meeting strict global legislative emission standards.
The IWMF involves a WTE Plant, a mechanical treatment plant and subordinate offices, which incorporate an organisation building, guest focus, port taking care of offices, and desalination and wastewater treatment plants. Contracted to treat around 3000 tons every day of blended civil strong waste, the WTE Plant will include Keppel Seghers’ demonstrated WTE innovation with its air-cooled grind, heater outline, and propelled burning control framework.
What’s more, the WTE Plant will likewise utilize Keppel Seghers’ flue gas cleaning framework, guaranteeing that the plant’s discharges will consent to Hong Kong and EU norms, which are among the most stringent worldwide measures accessible. Equipped for creating roughly 480 million kilowatt-hours (kWh) of gross power every year, the surplus power past plant consummation.
Keppel Seghers offers several flue gas cleaning system options: the dry scrubber, rotary atomiser, dedinox and filter. Each of these technologically advanced pieces of equipment provides additional catalyzation processes that help reduce the emission of any facility.
The first example of the flue gas cleaning system is the Keppel Seghers Dry Scrubber which was carefully designed to help facilities remove acid components, metals and dioxins from flue gases, consequently helping with emission reduction. The acid components are neutralized by reagents, while heavy metals and polyaromatic compounds are absorbed by carbon and lignite in their activated state.
This process benefits in several ways. First of all, the recirculation of gas eliminates the pollutants reaching spikes and excursions to the exhaust stack. This prevents wall build-up and clogging. The entire process requires low energy and its maintenance is reduced to the minimum. The semi-dry scrubbing fuel gas cleaning system captures pollutants by producing finely dispersed lime slurry droplets which mix and prevent the flue gas to be dispersed back into the air.
After being introduced with only one of several flue gas cleaning system components, we understand that the designers of these machines from the company have analyzed and carefully developed containers that allow gas purification with the aim to reduce emission. The investment process seems to be a one time focus, with minimal additions in the future. It is such machinery that can help reduce and maintain a higher quality of life in Hong Kong, China and the entire world.
