INCaF Villa Dominico

completed

CEAMSE operates/manages a landfill located near the southern suburbs of Buenos Aires. The landfill contains approximately 47,000,000 tonnes of municipal waste in an area of about 298 hectares. It is partially covered with a layer of clay.Van der Wiel Stortgas, VDWS, will install a gas collection and flaring system at the landfill in order to reduce emissions of greenhouse gases from the landfill to the atmosphere. The following equipment will be installed: a gas collection network, comprising permeable vertical pipes and horizontal gas drain mats; blowers to draw the gas to the flare, at least one high temperature gas flares; biogas monitoring and control equipment; civil works; possibly one or more gas engines with gas cleaning equipment (optional); electrical connections and back supply systems to the public grid; telemetric and other.The gas collection system will include a network of approximately vertical and horizontal gas extraction and collection wells, dewatering units to remove condensate, and several thousand meters of HDPE pipelines. The control activities for this system consist of periodic adjusting of the gas wells based on outputs from regular monitoring / measuring equipment that track gas flow, methane content and oxygen content among other parameters. Local operators, of Van der Wiel’s subsidiary company Van der Wiel Argentina SA, will be trained to install the equipment. Maintenance will include control of subsiding and/or distortion of gas wells and the pipeline system by local companies.The gas extraction equipment includes blowers to create a suction to extract the LFG. Once extracted, the LFG will be flared in a ‘low emission’ with high temperature flare (min. 900oC, retention time > 0,3 s). Local personnel, of Van der Wiel’s subsidiary company Van der Wiel Argentina SA, will be trained to install the extraction equipment, and they will have access to the telephone helpdesk of Van der Wiel Stortgas to obtain technical support. Van der Wiel Stortgas experts will undertake maintenance every 6 months. The plant will have an electrical control system equipped to monitor methane, oxygen, flow, pressure and temperature.
