Environmental technology for droplet seperation industry

by Körting Hannover AG     based in Hannover, GERMANY

As component of the gas scrubbing plants or as single apparatus Körting swirl droplet separators for seperating droplets and recondensates make an essential contribution towards the observation of emission codes and therefore towards the protection of the environment. They are used in gas scrubbing and vacuum plants, for condensate separation in chimney stacks, in evaporating plants as well as for the separation of difficult products (e. g. those with a tendency to polymerisation).

Industrial dedusting

The industrial dedusting field is very varied and branches out in numerous specialized branches. For a preliminary examination of the problem it is necessary to dispose of two series of data: characteristics of the system which emits the pollutants; nature of pollutants and their characteristics.

Sulfide Oxidation with Hydrogen Peroxide (H2O2)

by USP Technologies     based in Atlanta, GEORGIA (US) (USA)

Sulfide Odor Control Sulfide is found throughout the environment as a result of both natural and industrial processes. Most sulfide found in nature was produced biologically (under anaerobic conditions) and occurs as free hydrogen sulfide (H2S) - characterized by its rotten egg odor. We are most likely to encounter biogenic H2S in sour groundwaters, swamps and marshes, natural gas deposits, and sewage collection/treatment systems. Manmade sources of H2S typically occur as a result of natural materials containing sulfur (e.g., coal, gas and oil) being refined into industrial products. For a variety of reasons - aesthetics (odor control), health (toxicity), ecological (oxygen depletion in receiving waters), and economic (corrosion of equipment and infrastructure) - sulfide laden wastewaters must be handled carefully and remediated before they can be released to the environment. Typical discharge limits for sulfide are < 1 mg/L. Sulfide Treatment Alternatives There are dozens of alternatives for treating sulfide laden waters, ranging from simple air stripping (for the low levels present in groundwaters) to elaborate sulfur recovery plants (used to treat several tons per day at refineries and coal burning power plants). There are processes based on biology (using compost filters, scrubbing media, or inhibition/disinfection), chemistry (oxidation, precipitation, absorption, and combination), and physics (adsorption, volatilization, and incineration). Each process occupies a niche which is often defined by the scale and continuity of treatment, whether the sulfide is in solution or is a gas, the concentration of sulfide involved, and the disposition of the sulfide containing medium. However, for reasons relating to convenience and flexibility, chemical oxidation (using hydrogen peroxide) continues to grow in its scope of application. Treatment with Hydrogen Peroxide While other peroxygens such as permonosulfuric (Caro’s) acid, peracetic acid, and persulfates will oxidize sulfide, their use for this application is overkill. Hydrogen peroxide (H2O2) is considerably simpler and more cost-effective. H2O2 may control sulfides in two ways, depending on the application: Prevention - by providing dissolved oxygen which inhibits the septic conditions which lead to biological sulfide formation; and Destruction - by oxidizing sulfide to elemental sulfur or sulfate ion.

Carbon capture and storage (CCS) applications

by Gasmet Technologies Oy     based in Helsinki, FINLAND

Carbon Capture and Storage (CCS) is an emerging method of reducing greenhouse gas (GHG) emissions of power plants. In a process called ‘scrubbing’, the carbon dioxide emissions can be absorbed into chemical solvents consisting of amines or carbonates. Scrubbing is a well-established method of carbon capture, with virtually every commercial CO2 capture plant in operation using this process. In the process, the first step is the removal of impurities from the flue gas, such as hydrocarbons and oxides of both nitrogen and sulfur (NOx and SOx). Next the purified gas is passed through an absorption column filled with the chemical scrubbing solvent. The solvent reacts with the carbon dioxide and selectively absorbs it from the gas stream. When CO2-rich solvent is heated, the carbon dioxide is released as a nearly pure gas.

Odor Scrubbers Applications with Hydrogen Peroxide

by USP Technologies     based in Atlanta, GEORGIA (US) (USA)

Hydrogen Peroxide as a Replacement for Sodium Hypochlorite Hydrogen peroxide may be used in both mist scrubbers and packed tower scrubbers as a replacement for sodium hypochlorite (bleach). Like bleach, the process involves two concurrent mechanisms: 1) absorption of the odors (H2S) into the alkaline scrubbing solution; and 2) oxidation of the absorbed sulfide in solution. Step 1: H2S + NaOH → NaSH + H2O Step 2: 4H2O2 + H2S → H2SO4 + 4H2O Typical dose ratios are 5 parts H2O2 per part H2S or, when used in place of bleach, one gallon 50% H2O2 for every 10 gallons of 15% sodium hypochlorite (NaOCl). This generally translates into a break-even cost scenario. Sufficient caustic soda (NaOH) is added to maintain a pH of 10.0 - 10.5 in the scrubbing solution. There is also in practice a process which uses H2O2 in series with bleach to scrub composting odors. This process relies on a series of three packed tower scrubbers: the first is a pH neutral water wash (to remove ammonia and amine odors); the second uses a conventional caustic/bleach solution in which the bleach is purposely overdosed (to oxidize the complex organic sulfur odors); and the third uses a caustic/H2O2 solution (to remove the unreacted chlorine vapors carried over from the second stage). H2O2 + HOCl → HCl + H2O + O2 Typical dose ratios are 0.5 parts H2O2 per part hypochlorite (OCl-), with sufficient caustic soda (NaOH) added to maintain a pH of 8.5 in the scrubbing solution.

Air scrubber wastewater solution

by ENCON Evaporators     based in Hooksett, NEW HAMPSHIRE (USA)

Air Scrubbers strip out contaminants from exhaust stacks typically by trickling a stream of salt solution through a bed of media to extract contaminants by putting them into solution. The salts found in these solutions are typically sulfates, chlorides, and carbonates. Air Scrubber wastewater tends to have high total dissolved solids (TDS) or salts. Air Scrubber Wastewater cannot be simply flushed down the drain. Many companies choose to avoid the headaches of labor-intensive wastewater treatment technologies such as chemical treatment or filtration and simply pay to haul the wastewater. This however, can become quite expensive.
