Ecochimica System s.r.l. products

Biogas, if not dehumidified cannot be sent directly through the cogeneration engine.

Operating Principals: The plant basically consists of three vertical chambers filled of high thermal capacity ceramic material (a preheating inlet gas chamber, a heat recovery of purified gas from combustion chamber and a cleaning chamber with fresh air) and a combustion chamber with modulating burner that connect up the 3 chambers. The gas with V.O.C. undergoes a preheating phase crossing from the lower part to the upper of the ceramic bed in the first chamber until a temperature near 750 - 800°C.

Operating Principals: The unit is mainly made up with a shell and tube heat exchanger and a combustion chamber equipped with a modulating burner. The gas containing V.O.C. is preheated passing through the shell and tube heat exchanger up to a temperature close to 450 ÷ 550 °C by mean of the heat released by combustion gases which pass through the shell side of the same heat exchanger, and then it passes through the combustion chamber where the modulating burner, which is normally fed with natural gas, supplies the amount of energy needed to reach and keep constant the temperature at which complete thermal oxidation of V.O.C. occurs and finally releases the heat absorbed, passing through the shell side of the heat exchanger, cooling itself down to a temperature bigger than the inlet one of 200 ÷ 300 °C and is emitted cleaned to atmosphere.

Operating Principals: In anaerobic fermentation of waste for biogas production, the methane produced contains high levels of hydrogen sulphide which is highly corrosive to the energy production unit. Ecochimica’s desolf equipment reduces the quantities of hydrogen sulphide with a 90% efficiency and through careful chemical cleaning of the biogas.
