FORCED DRAFT DEGASIFICATION PRE AND POST CATION AND ANION EXCHANGE

Posted by Anthony DeLoach on Oct 23, 2018 7:49:53 AM

In the production and purification of water for industry there are many types of different processes available to remove harmful minerals and gases from the water stream but the most effective process and most cost effective from both a capital investment and operational cost is a “Forced Draft Degasification System” (Degasifier).

Degasification is used in a wide range of water processes

for industrial and municipal applications which extend from the production of chemicals to the production of semiconductors and in all applications the need to remove contaminants from the water and dissolved gases is key to achieving the end results needed in the industrial water process. Water from the ground often contains elements such as calcium carbonate, manganese, iron, salts, hydrogen sulfide, and sulfur just to name a few of the basic contaminants and these naturally occurring elements can cause serious damage and consequences to process equipment such as boiler systems, piping, membranes, and cation and anion exchange resins used in the demineralization process.

Calcium carbonate can dissolve in water under certain pH ranges forming carbonic acid and releasing carbon dioxide (CO2) gases. These gases are not only very corrosive to equipment like boiler feed systems and boiler tubes but also attack the actual resin beds found in cation and anion softening and demineralization system causing an increase in regeneration and chemical consumption and resin bed replacement.

By incorporating a Force Draft Degasification system you can remove dissolved gasses

like CO2 and hydrogen sulfide (H2S) to as low as 99.999% and improve the cation and anion system performance, extend the resin bed life, and lower the operating cost of the water treatment process.

Quite often Forced Draft Degasification is utilized “post” treatment to also remove newly formed dissolved gases prior to entering the boiler feed system to prevent corrosion damage within the tubes and feed system and pumps. These gases are easily removed with the forced draft degasifier at a much lower cost than chemical additives or liquid cell degasification that requires higher capital cost and much higher operating cost.

Aqua Farming

Posted by Anthony DeLoach on Sep 11, 2018 9:09:00 AM

To enhance and control production and quality

of seafood that is grown and harvested the industry is increasing its focus on the construction of in house aquaculture fish farms commonly referred to as aqua farming. The most popular species of aqua farming continues to be salmon, tilapia, catfish, and carp. With the increase interest in the United States aqua farming facilities have been developing in parts of southern Florida where climate conditions and water conditions are favorable.

When considering several types of fish species to grow for harvest it is important to keep in mind the need to control the quality of the water. If the aqua farm is intended to utilize man made tanks they will depend upon a constant flow of incoming water. If the aqua farm is focusing on salmon then both the water quality and water temperature plays a major role on mortality rates and production yields of the operation.

Having water with too high of hydrogen sulfide, carbon dioxide, total Organic carbons, and even turbidity can increase mortality rates among the younger fish species and is especially critical to salmon.

Aquaculture

Water Treatment

When planning and designing a man made on land aquaculture or pisciculture facility the most important key element is the quality of the water. For operations developing in Florida or the Caribbean it is important to remember that water quality varies in Florida and other states in the US and typically requires some type of water treatment. For fresh and salt water land based farms that utilize tanks located inside of a building the water needs to be treated and pure from any naturally occurring contaminants such as hydrogen sulfide (H2S), iron (Fe+), and even carbon dioxide (CO2).

The most cost effective way to treat incoming water for aquaculture farming and remove hydrogen sulfide, iron, and lower carbon dioxide is the use of a “degasification” tower. A degasification tower or degasifier is a piece of process equipment. Degasifiers can also be referred to as a “decarbonator” or “air stripper” or even “aeration tower”. The degasification tower is a vertical column designed to remove certain types of contaminants by “stripping” the molecules of converted gases and expelling them from the water as a gas. The science is based upon “Henry’s Law” and it relies upon the disproportionate varying vapor pressures of gases.

Aqua Farm E-BookIf the incoming raw water contains levels of sulfides or hydrogen sulfide gases it is recommended to remove the hydrogen sulfide to improve the water quality and reduce the risk of the development and formation of bacteria that can thrive on the Sulfur. In addition hydrogen sulfide is corrosive and will cause harm to other components within the process if left untreated. It is important to adjust the pH of the raw feed water prior to degasification to ensure full conversion of the sulfides into hydrogen sulfide gas (H2S) to enable the degasification process to perform and remove up to 99.99% of the harmful contaminants without adding additional chemicals. This saves money and improves quality of the product!

Sour Gas Degasification

Posted by Anthony DeLoach on Aug 28, 2018 12:31:07 PM

The Term Sour Gas

refers to any natural gas or other gas that contains high levels of hydrogen sulfide (H2S). The H2S is typically naturally occurring and found in deposits of natural gas and when there are concentrations above 5.7 milligrams per cubic meter or 4 milligrams per cubic meter when tested under standard temperature and pressure. At these levels the industry classifies the gas as “Sour.” Of course there are variations to this classification dependent upon agency an organization.

A Sour gas is not to be confused with an acidic gas 

although one could be both a sour gas is strictly defined by having large quantities of hydrogen sulfide and is usually accompanied by having mercaptans which adds to the foul smell and odor. The term is often used in the oil refinery business and when gases contain sour gas the process to remove the hydrogen sulfide and mercaptans is referred to as “Sweetening”. The most common method to “sweeten” and remove the sour gas is by processing the gas through an “amine process” which removes the harmful gas.

Reverse Osmosis-A walk in time

Posted by Anthony DeLoach on Aug 21, 2018 8:53:00 AM

DeLoach Industries made history in 1977 at the City of Cape Coral Florida water treatment plant with its large scale “degasification towers” connected to what was to become the first municipal water treatment facility in the United States to deploy the use of reverse osmosis on a large-scale production municipal treatment plant.

The Cape Coral water treatment plant for came on line in 1977 and produced 3 million gallons of water per day (GPD) or 11.35 liters of purified and treated water utilizing the “reverse osmosis” process. By 1985 the plant had expanded as it kept up with growth to produce 15 million gallons per day making it at the time the worlds’ largest “reverse osmosis” water treatment plant facility.

Caustic Scrubber

Posted by Anthony DeLoach on Aug 21, 2018 8:51:00 AM

There are many industries that require the use of a caustic scrubber which is considered a chemical scrubber and they range from the municipal industry, mining, semiconductor markets, pulp and paper and chemical refining.  There is a wide variety of industrial processes that generate noxious or corrosive off gases that require treatment and a comparison is made about biological Vs. chemical.  Often biological scrubbers have limitations due to concentrations, composition, or temperature of the contaminants and if the gas stream contains acid fumes then a biological scrubber is quickly ruled out.

Odor Control E-BookThe odor control selection is often fraught with choices of capital cost over operational cost and quite often comes down to familiarity from the designer or purchaser.  It is always a good idea to freshen up on the industrial odor control the do’s and don’t’s before selecting the final solution.  If the off gas source that needs to be treated is hydrogen sulfide (H2S) or some other type of gas stream produced by an acid or ammonia it will often require neutralization for human health reasons and to protect equipment or may be required to meet regulatory compliance. Caustic scrubbers may be either vertical or horizontal by design, but both utilize a packed media bed of either random packing or trays to allow the gas fumes to meet the recirculating caustic solution which then forces the reaction to occur.

Odor Control Selection

Posted by Anthony DeLoach on Aug 16, 2018 9:03:00 AM

What type of Odor Control Scrubber do I select?

Odor Control E-BookIt's a common question many customers and design professionals ask in the Odor Control Industry when it comes to selecting, engineering, and making the decision on the best type of odor control process to utilize to treat off gases and noxious odors. Selecting an odor control system is comparable to choosing a car in many ways because you have a lot of different options to choose from and each odor control scrubber comes in different types to address the different variations within the industry.  As an example, there are odor control scrubbers designed to treat “ammonia” gases and other ones to treat “acid” off gases.  Or there are odor control scrubbers that utilize “acid” or “caustic” as the scrubbing reagent in the process to neutralize an off gas.

Odor control scrubbers also come with different purchase prices and each have different operating costs associated with them.  It is always important to analyze the operating cost of the odor control solution you select because there may be several different types that may all perform equally and each may have varying initial purchase costs but you should ask the question and understand “what will be the continued operating cost” be for the type of odor control system selected.  And how long will the scrubber I selected last before additional costs are needed for any major repairs to keep it running? When you are a design professional if you choose the odor control system that is difficult or expensive to maintain then you can be assured you will have continued phone calls from customers looking for answers and solutions.

Odor Control with Artificial Intelligence

Posted by Anthony DeLoach on Aug 14, 2018 8:55:00 AM

Would it be possible for our odor control scrubbers to communicate with us and tell us when there are problems? Or when they need service? With the new technological revolution, we are now into this is quickly becoming a reality. DeLoach Industries is rapidly changing how water treatment and odor control and air emissions are treated with new advancements in artificial intelligence and integration into proven technologies.

Most operators will tell you that to keep and maintain an odor control system whether its Biological Vs. chemical can be quite challenging depending on the type and source of the off gas to be treated and depending on the type of chemical reagents being utilized such as acid or caustic solutions. When odor control systems such as a biological scrubber are met with a varying flow rates, corrosive gases, or spiking concentrations an odor control system can be daunting to keep in balance and operating efficiency. But what if they could think or communicate with other devices or even operators for themselves? What if they could make corrections in caustic feed rates because of ammonia (NH3) concentration spikes, order chemicals like caustic or acid for pH control, and even inform us when they anticipate a problem for either the odor control scrubber or another critical component that it depends upon? That time has now arrived that’s to DeLoach Industries new advancements to their equipment systems.

Biological Scrubber

Posted by Anthony DeLoach on Aug 9, 2018 8:18:00 AM

Odor Control E-BookBiological Scrubber is a type of wet odor control scrubber that treats and removes contaminants from an air stream that only utilizes caustic typically to control the pH of the re-circulation solution. There are several types of odor control and chemical fume scrubbers on the market today and each of them play a role in the treatment of noxious or corrosive gases in the industry. Biological scrubbers are commonly utilized in municipal applications for the treatment of hydrogen sulfide (H2S) gases that are removed from a water or waste water treatment process.  In water treatment equipment such as a “degasification” or “decarbonation” tower strips the hydrogen sulfide gas from the water and exhaust the gas from an exhaust port.  These gases are captured and sent via a air duct system to the biological scrubber.  Hydrogen gases captured at a wastewater treatment process which may include the treatment plant, lift station or head-works facility are also sent using a PVC or FRP duct system to the biological scrubber.
