Product Name: Landfill Biogas Purification/Pre Treatment Power Plant Model NO.: ALONG BIOGAS -Landfill Waste Type: Landfill Trademark: ALONG BIOGAS Transport Package: LCL or FCL Specification: Complete System Origin: China HS Code: 8486909000 Product Description Landfill is the site for stacking of municipal refuse. A big landfill under proper design could produce a considerable amount of biogas, as a great green energy for power generation.A sanitary landfill is always equipped with perforated tubes, which are connected to suction and purging system, to delivery gas to the site for conversion.Landfill gas contains methane(40~70%), carbon dioxide(30~60%), hydrogen sulfide, saturated water vapor, high hydrocarbons(C2H6- C7H16), oxide of ammonia/nitrogen/oxygen/sulfur/alkanes /acids/benzene/silicon, salts and even physical particles. And its flow, pressure, temperature and concentration are unstable, direct combustion in engine would cause corrosion and grinding for generator and other relevant equipment, as well as pollution for atmosphere. So it must be cleaned before the use;Our GasPro system is designed to preform this role of converting landfill gas, with functions of dehydration, dehumidification, edulcoration, boosting, pressure-stabilization, thermoregulation, automatic/remote controlling and on-line detecting,etc.Filtration; Physical particles could be observably removed;Multi-stage dehydration could reduce the temperature of gas dew point,as well as the water vapor content;Freezing function for condensation and precipitation of harmful gases;Adjusting gas temperature in proper condition to feed engine;On-line detecting system for measuring gas composition timely(optional);Advanced control system could stabilize the gas outlet pressure and temperature;The gas flow is automatically tracked rooted on the requirements of engine;Equipped with alarms and protections for over-pressure and over-temperature, to ensure safe and reliable operation of system in the long-term;This matched system could make engine runs under condition of fixed thermal value, to improve the stability of engine operation and protect the gas collector.GasPro system uses programmable controller - PLC control, with functions of data acquisition, on-line detection and alarm. Standard communication interface to be provided in synchronization with the owner's control system per clients' requirements, to achieve the purpose of unattended and fully automatic operation:A programmable PLC controller for data acquisition and processing;With function of remote data transmission;Through standard industrial Ethernet to read data when system in operation;Site controlling mode at local engineering station by the use of LCD touch screen. Through data transmission to achieve the purpose of remote controlling, eg. start/stop signal;The use of professional computer for processing of data and signal. Configuration software and past records are stored in the hard risk of computer;Within authorized scope, engineer could modify the parameter settings of alarm and shutdown.Flow-chart of GasPro system for converting landfill gas:Landfill gas is mainly used for power generation in actual projects. They are always big scales, big generators or CHPs installed with synchronization with national grid. So stability of feed gas at pressure, temperature and cleanliness is very important to guarantee the life time of the valuable generators, to get reliable ROI(Return on Investment).
