France-headed thermal energy system provider Leroux & Lotz Technologies (LLT) has announced that it has signed a contract with Netherlands-based with Eska Graphic Board B.V., for the design, manufacture, and commissioning of a 12 MWth reject gasification facility in Hoogezand, the Netherlands. The commissioning of the plant is expected in the second half of 2016.
Eska Graphic Board is a leading graphic board producer that uses 100 percent recycled paper to produce over 250 000 tonnes of graphic board per annum in its two state-of-the-art plants in Hoogezand and Sappemeer. When waste paper is processed into a solid board, there are residues left over from the pulping process. Known as rejects, these residues consist mainly of plastics and are currently transported off site for incineration.
In the new gasification facility to be supplied by Leroux & Lotz Technologies (LLT), 25 000 tonnes of rejects will be treated annually to generate a syngas. This syngas will be combusted in a new waste heat recovery boiler which will generate 16 tonnes per hour of 16 bar saturated steam. The steam will be used on-site in the solid board production process.
The on-site energy recovery of the rejects with the gasification solution is expected to save 18 million Nm3 of fossil gas annually, optimize the energy efficiency of the board plant and contribute to achieving the 2020 targets set for the Paper and Board sector of reducing energy consumption and carbon dioxide (CO2) emissions.
Strategic advanced conversion project
According to a statement, the turnkey gasification solution to be provided by LLT includes the complete “crane to stack” boiler island including the gasifier, recovery boiler, flue gas treatment – and integrated fuel storage and preparation as well as the operating system for the installation. The commissioning of the reject gasification plant is expected in the second half of 2016.
This first reference in the paper industry for our gasification system is a remarkable opportunity for the development of sustainable solutions for energy production on industrial sites. In addition to LLT’s conventional combustion technologies, the gasification technology is available to be commercially deployed for thermal utilization of waste, said Patrick Blanc, Director of Leroux & Lotz Technologies Heat & Power.
According to Blanc, its gasification technology benefits from three decades of LLT’s experience in laboratory scale and industrial installations. It’s circulating fluidized bed (CFB), air at atmospheric pressure, is ideal for energy recovery of complex solid fuel including refuse-derived fuels (RDF) to deliver outputs to in excess of 5 MWth. LLT has paid special attention to the design of the boiler and flue gas treatment systems to minimise air emissions in strict compliance with environmental regulation as well as to minimise the environmental footprint of the installation.
