H2S Reduction

Hydrogen sulfide (H2S) is a chemical compound produced by the microbial breakdown of organic matter in the absence of oxygen. H2S is commonly found at oil and natural gas well sites, petroleum refineries, and in pipelines used to carry crude oil and natural gas. The concentration of H2S is typically dependent on the oil well location, depth, and quality. Hydrogen Sulfide is toxic to humans, can easily explode, and corrodes metals and equipment it touches. The oil and gas industry thus takes great measures to ensure safety at an oil site and is constantly seeking ways to reduce H2S throughout the various stages of oil production. Moleaer's nanobubble technology is a highly effective treatment method that rapidly and efficiently reduces H2S.

High Oxygen-Transfer Efficiency

The primary method to treat H2S is to oxidize it, or make it react with oxygen, to form insoluble solid sulfur. Moleaer's nanobubble gas-injection technology has a very high oxygen-transfer efficiency (OTE) because of the size of the nanobubbles, less than that of a human red blood cell. At this size, the bubbles provide more than 400 times the interfacial surface area of ultrafine bubbles. Moleaer's system also produces nanobubbles in high quantities, over one billion per milliliter of water. The combination of their miniscule size and high volume translates to an OTE of over 90%, making it a very effective treatment method for H2S.

Mixing and Distribution

Due to the nanobubbles' neutral buoyancy and Brownian motion, they evenly disperse, enabling them to evenly oxygenate the entire water column, thereby achieving the same DO level at all depths of a frac or produced water pond. This is particularly important because the presence of oxygen at lower depths prevents the hypolimnion, the dense bottom layer of water, from becoming anoxic which would otherwise allow sulfate reducing bacteria to produce H2S. Nanobubbles also survive in solution for months at a time due to their strong surface charge and neutral buoyancy. This makes them ideal for H2S prevention in ponds after the water has been oxidize upstream.

Non-invasive Plug & Play Solutions

Moleaer's nanobubble generators are positioned outside the body of water. Customers can typically install and commission a Moleaer system in half a day by simply connecting PVC or flexible hoses to and from the generator to the body of water and connecting the generator to a power source. These simple to install, energy efficient systems, help Oil & Gas operators eliminate and prevent H2S in their ponds more cost effectively than the use of traditional, invasive aeration systems combined with chemistry.
