We design and build modular gas collection systems with collectors to capture emitted gases. Each collector branch includes a flow meter, and the flow and oxygen content are controlled by ball valves. In addition, each branch has a gas composition check collection station. The key factors are the number of wells in the collector, which may range from 3 to 50 units, and the gas flow, which can range from 10 to 1000 m3/h. The modular collector is completely assembled and ready to use. In addition to collectors, we can provide gas extraction and compression modules.
