MINI-CAT™ was born out of the LO-CAT® H2S removal technology which treats sulfur loads between 1,000 kg/day and 25+ tons per day. With MINI-CAT™, Gas Technology Products LLC is building on this tradition of simplicity and success by pre-engineering virtually the entire plant for sulfur loads between 200 – 1,000 kg/day.
With this simple change to a commercially successful technology in operations for 27 years, the result is nothing short of revolutionary. Capitol cost may be reduced significantly compared to a similar custom designed unit. And delivery and installation time may be reduced by as much as 50%.
MINI-CAT™ is cost-effective in removing H2S in numerous applications including landfills, municipal waste, and biogas treatment.
In comparison to old fashioned "scavenger" H2S removal systems MINI-CAT™ will reduce chemical costs up to 80% (more if you use a liquid scavenger), continuously remove H2S without unexpected sulfur breakthrough, eliminate the need for reactor changeouts, and cut waste products in half.
Removing H2S From Landfill Gas (LFG)
Gas Technology Products offers a line-up of costeffective,
environmentally-friendly, and powerful H2S
removal systems that are adaptable to landfill gas
treatment applications.
The MINI-CAT™ process, based on proven LO-CAT technology, treats smaller H2S loads using the same chemistry as LO-CAT. However, MINI-CAT™ is especially attractive and cost-effective for many landfill gas applications as a modular option with lower capital cost than LO-CAT. MINI-CAT™ units are pre-fabricated, skid-mounted, have a small footprint, and offer expanded flexibility for variable landfill gas flows and H2S concentrations.
MINI-CAT™ is a water-based H2S removal process for landfill gas applications with higher H2S concentrations. Typically, LO-CAT is used for removing 1,000 – 10,000 kg of sulfur per day as H2S; MINI-CAT™ for removing 200 – 1,000 kg (440 – 2,200 lb) sulfur per day as H2S.
The patented LO-CAT® (liquid oxidation catalyst) process uses an iron chelate solution to oxidize the H2S to elemental sulfur and water. The iron chelate solution is then continuously regenerated using air, resulting in much lower operating costs than non-regenerable scavengers. The elemental sulfur product can be used for agricultural applications—so it is not a waste product requiring disposal.
Different configurations are employed to yield better than 99.9% H2S removal. In the mobile bed absorber configuration, moderately low pressure gas streams are contacted counter-currently with LO-CAT solution using spherical balls to aid in mixing. Venturi contactors are used for low pressure, high volume gas streams where the required sulfur removal efficiency is lower. In all configurations, the elemental sulfur is separated, the LO-CAT solution is regenerated with air in a separate Oxidizer vessel, and the solution is circulated back to the absorber.
