Decreasing Amine Consumption

Posted by Anthony DeLoach on Jun 19, 2018 8:05:00 AM

Many times, process systems will fail to recognize when the Degasification or Decarbonation system is failing or under performing. One critical signal that can be used as a verification is when a process also utilizes Amine in the downstream treatment the consumption rate will increase which can drastically increase operational cost. When a packed column tower begins to fail it can be associated with fouled media, a failed distribution system, plugged intake vents, or a failed or failing blower. Often in high noise environments it is difficult to notice if a belt has broken or slipped on a Decarbonation blower and the control room may still be showing that the blower motor is operational. However, the air flow has ceased and the removal efficiency of the Carbon Dioxide (CO2) has decreased. Frequent inspections are needed to assure performance with routine inspections and cleaning of the internals.

De-Aeration Vs. Decarbonation

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

The term De-Aeration refers to a specific process utilized to remove carbon dioxide as well as dissolved oxygen from a water stream. Typically associated with boiler feed water systems and utilized as a method to remove CO2 and O2 from the water prior to entering the boiler. The Decarbonation system also removes CO2 from the water and typically does not target the removal of O2. A De-Aeration system utilizes steam which enters at the bottom of the tower. The inlet feed water is heated, as close to saturation temperature as possible utilizing a minimum pressure drop and a limit on the vent. This ensures the best thermal operating efficiency of the tower. The Decarbonation tower utilizes a counter current of air generated by a blower and enters into the tower also at the bottom and travels upward unless the system is an “Induced Draft” system and then the blower is located at the top of the tower and it pulls air up and through the unit. Both types of systems utilize an internal distribution system as well as a media packing to enhance the removal of the dissolved gases.

How to protect your pharmaceutical water

Posted by Anthony DeLoach on Jun 12, 2018 12:00:00 AM

The need to remove dissolved gases from water in the pharmaceutical process is well known within the industry. However, the method of removing the gases varies and depending on the quality of the water a wrong selection can wreak havoc on your process water equipment, such as the steam boiler or distillation columns.If the water contains high levels of carbon dioxide (CO2) than it can form carbonic acid which will attack and corrode both the steam boiler tubes as well as the distillation columns.Removing the dissolved gases by adding a Degasification tower or “Degasifier” will ensure that the dissolved gases like Hydrogen sulfide (H2S) and Carbon Dioxide (CO2) have been removed to acceptable levels of below 7 ppb. Also utilizing a degasification tower is the most cost-effective way to reduce and eliminate the gases in the water stream.R.O. membranes are used to and require pH adjustment to achieve the same results because of the need to convert the CO2 into carbonates first.This often leads to an increase in membrane fouling and the capital cost of the RO system far exceeds the capital cost of the degasification system or its operating cost.

Why remove carbon dioxide from water

Posted by Anthony DeLoach on Jun 7, 2018 12:00:00 AM

Carbon dioxide (CO2) exists naturally in nature as free CO2 and can be found in many water sources from lakes, streams, or other surface water bodies. Having free carbon dioxide (CO2) in a water process causes an ionic load problem for ion exchange. Resin treatments such as ion resins or continuous deionization (CDI) systems. Having CO2 in the water system causes several problems for the ion exchange process that includes an increase of regeneration, reduction in resin bed life, and of course more down time of the equipment for maintenance. The most economical way to remove free Carbon Dioxide (CO2) is by utilizing a process called “Decarbonation” or sometimes referred to as “Degasification”. Utilizing the decarbonation process will remove CO2 levels to 99% or higher. DeLoach Industries offers a wide range of decarbonation and degasification equipment for municipal, pharmaceutical, food and beverage, and the industrial markets.

Saving steam with degasification

Posted by Anthony DeLoach on Jun 5, 2018 12:00:00 AM

At most, business operations that utilize steam there is an awareness of both the potential short supply as well as the ongoing operating cost to produce the stream. Steam is utilized from simple task of heating buildings and pipes to more complex operations like distillation for use with the food and beverage markets or pharmaceutical industry. Oil refineries desperately depend on steam and is part of their key foundation of their operation. When designing a system it helps to reduce the need for steam whenever possible, by selecting water treatment processes that are not dependent on steam such as a “Decarbonator”. Decarbonators can remove Carbon dioxide (C02) without the use of steam saving the customer thousands of dollars a month in operating costs and shifting the steam load to other much more needed applications. CO2 can be reduced in a decarbonation system and produce efficiency as high as 99% or higher. This process will extend the life of the Ion exchange systems commonly utilized in conjunction with steam generation.

The process of removing dissolved gases from feed water to steam-generating boilers is often referred to as “De-Aeration”. During the de-aeration process dissolved oxygen (02) and carbon dioxide (CO2) are removed prior to entering the boiler. If the gases are not removed prior to reaching the boiler system, the boiler will experience serious corrosion damage. The gases, when in contact with the metallic equipment will form oxides (rust) and it will attach to the walls of the piping and tubes and over time completely shut down the boiler. The dissolved carbon dioxide combines with the water and forms carbonic acid that also further enhances the corrosion process. Most de-aerators utilize steam to enhance the removal of the dissolved gases and levels are typically reduced to 7 ppb by weight or less for the oxygen (02) and the removal of carbon dioxide (CO2). For a system only needing CO2 removal then a decarbonator is typically used as it operates without the need for steam and for much less operating cost.

Recycling wastewater for safe drinking water

Posted by Anthony DeLoach on May 29, 2018 12:00:00 AM

Over the last 2 decades there has been vast development and improvement of wastewater technologies treatment processes that have been driven by both need and governmental regulations. Today, municipalities and Countries are recognizing the need to recycle wastewater into drinking water and in locations such as the Caribbean and other foreign nations the wastewater to drinking water industry is more of a “must” than a choice. To meet our global needs and challenges the need to recycle wastewater to clean drinking water has become an everyday occurrence driven by new technologies such as “Ultra-Filtration” or “Membrane Bio-Reactors” (MBR). These technologies continue to advance and provide much needed solutions for the world. Because of stricter governmental requirements for utilizing wastewater recycling most often the purity standards in the process exceed the standards in normal water treatment. To continue to grow on a global scale, all professionals and consumers must recognize and adapt to the need to recycle wastewater when and where it is applicable to meet our needs.

Caribbean water treatment challenges

Posted by Anthony DeLoach on May 24, 2018 12:00:00 AM

Water treatment in the Caribbean offers distant challenges for water professionals. During the design process an engineer must examine multiples aspects of a potential project to ascertain the most cost effective and most sustainable approach. Geographic location can become a major variable during the design selection process. As an example, if the location is remote, too often the shipping of liquid chemicals becomes a challenge as well as the training of operators to safely handle the chemicals during normal operations. The ability to secure trained operators may impact the success or failure of a water treatment process such as membrane separation, reverse osmosis and degasification or decarbonation not to mention odor control. Much thought must be given by the design professional and owner prior to selection of the water treatment process to assure a long term sustainable working solution. When a process is selected there should be a written plan on how operations and maintenance of the water treatment system should be operated and how the operators will be properly trained and monitored for compliance.

Saving your ION exchange resin for boiler feed by proper decarbonation

Posted by Anthony DeLoach on May 22, 2018 12:00:00 AM

During the process of water filtration, membrane separation and reverse osmosis, too often little attention is given to the need to properly remove CO2 from the process to lower the pH and adjust the alkalinity. Having a high level of CO2 and acidic pH will increase the consumption of ion exchange resins prior to the injection into a boiler feed process. The consumption of amine levels will drastically increase if the water process is not properly adjusted and the CO2 removed prior to water softening which can also add to ion exchange failure and an increased hardness level of the water, resulting in scaling inside of the boiler tubes. Always consult your manufacturer to optimize the removal of CO2 and balancing of the pH to avoid boiler damage.
