County District Landfill, New Jersey

Application:

MV received the RFP for this landfill gas desulphurization system in 2012. At that time, the owner was utilizing a liquid redox sulfur treatment system and determined the operating costs of the system were well over $7/lb. of H2S removed. Opex includes site maintenance personnel and electricity. Specifications required the landfill gas, with a flow rate of approximately 1,500 cfm, be reduced from an inlet concentration of 1,200 ppm H2S to less than 5 ppm. The desire to reduce operating costs was a key factor in guiding their decision to search for alternative H2S removal solutions. The site has a very strict air emissions permit as well.

MV Solution:

MV Technologies was awarded the contract through a general contractor, developing a three-vessel H2SPlus System for the municipal landfill. Utilizing our system, the owner was able to see operating costs reduced to less than $2/lb. of H2S removed. Additionally, since the H2SPlus System requires less operator attention, the site maintenance personnel are now able to focus on other tasks at the landfill. Each vessel, operating in parallel, contains 1,050 ft3 of MV’s enhanced BioActive Media, designed with a 180-day replacement cycle. The use of gas analyzers was successfully incorporated into the system, allowing the end-user to gather real-time data of inlet and outlet H2S concentrations. An O2 sensor is used to control the quantity of air introduced for the on-line media regeneration.
