TAS installed the first commercial Boreal Laser Gasfinder TDL units in 1996.

We have continued to work closely with Boreal continuously, installing dozens of systems, providing value-added products for new applications, and providing technical support to improve reliability through design, installation, operations, maintenance practices.

We have also added other partners to our array of high quality gas detection and monitoring solutions. TAS supports customers by providing effective solutions without a sales pitch and without being tied to any particular manufacturer.

A SAMPLE OF GASES WE WORK WITH

These are just a few of over a dozen gases TAS has worked with. Please contact us at info@tasysLLC.com to learn more.

Hydrogen sulfide (H2S)

A colorless, flammable, and extremely toxic gas that is emitted from natural sources and certain industrial activities, H2S is heavier than air and collects in low-lying, enclosed areas. The primary route of exposure is inhalation. In lower concentrations, H2S exposure causes eye, nose, throat, and respiratory irritation. Higher concentrations can induce shock. unconsciousness, and, in severe cases, death. Considering these hazardous effects. monitoring for H2S is a key factor in safeguarding personnel.

TAS is the world leader in H2S open path monitoring solutions. The health and safety of employees and sensitive populations surrounding a refinery or process plant is paramount. Although every employee onsite can rely on their personal H2S monitors. being able to detect a leak BEFORE an employee is exposed is invaluable. Furthermore. protecting nearby populations from leaks protects the community.

Although H2S is a tricky gas to monitor. TAS is at the cutting edge of new and improved technology. offering fast and reliable detection lightyears ahead of electrochemical sensors. Electrochemical sensors are poisoned easily and Optical Remote Sensing (ORS) systems can confused ammonia with water vapor. However, TAS has successfully installed dozens of open path H2S detection systems because we know what it takes to optimize the technology to your site's specific characteristics.

Ammonia (NH3)

Appropriate and effective sensing is critical to Ammonia/Urea operations for process safety as well as worker health and safety. Speed and certainty of detection are vital for process control and timely mitigation of accidental release. IDLH limits are effortlessly monitored using either UV-DOAS (Ultraviolet Differential Optical Adsorption Spectrometer) or TDL (Tunable Diode Laser) technologies. TAS has designed, installed and continues to maintain over eight open path ammonia detection installations with over four paths each. Understanding a sensor's characteristics is essential in designing and implementing effective systems.

A number of sensor products and systems have been commercially developed for application in industrial environments such as ammonia/urea production. Legacy sensors such as mass spectrometers and electrochemical detectors tend to have a high cost of ownership due to maintenance and calibration requirements. Optical sensors can be direct replacements for and improvements on these technologies with higher reliability and ease of use. Available optical sensors are based on different technologies. requiring different operational and use considerations.

Careful evaluation and planning are key to determining what equipment and methods to consider when applying optical sensing technologies in process and HSE applications. A successful implementation will include identifying the information needed. understanding the measurement and operations environment determining measurement needs and methods appropriate for the application, and then working closely with manufacturer and engineering support to design, install. and transition equipment into operations with forward-thinking planning for appropriate use and maintenance.

Hydrofluoric Acid (HF)

TAS is the expert in designing, integrating and maintaining HF detection systems. Boasting over fifty open path HF detection systems currently in use, TAS has the expertise. credentials, and understanding required to monitor even the toughest gas monitoring challenges.

When anhydrous or highly concentrated HF is released into the atmosphere it forms a very dense plume. This is the result of a number of chemical interactions including reactions with water and agglomeration of HF molecules into semi-stable oligomers or droplets. Often this results in released HF plumes behaving as a dense gas. They will move as if it is heavier than air, sloughing toward the ground. However. the HF molecule is lighter than air. As HF agglomerates or droplets break apart the HF gas behaves as a lighter than air gas and begins to loft.

Highly dense plumes of any type can block open path optical sensors. The density of an HF plume depends on the concentration of the release and the atmospheric properties at the time of release (temperature. humidity. wind speed. turbulence). Conditions of HF releases require advanced knowledge of the behavior of HF plumes and the phases of plumes within the varied geometric spaces of an industrial environment.

Hydrochloric Acid (HCl)

Hydrogen chloride (HCI) is a corrosive, flammable, and colorless gas with a piercing, pungent odor used for a variety of manufacturing processes and industrial chemical transformations. Effects of exposure range from mild irritation to severe burns of the skin and eyes. Additional risks include lung and heart issues and can even be fatal in extreme situations. Identifying hazardous levels of HCI is essential for establishing safe working environments and ensuring efficient industrial and manufacturing operations.

Monitoring hydrogen chloride has many effective solutions for various applications. TAS has extensive knowledge of HCI process emissions and storage and handling emissions for everything from bleach production to water sanitation. TAS has a proven track record of successful open path system installations at over 50 different sites worldwide.

Chlorine Gas (Cl2)

Chlorine gas (Cl2) is most often used for disinfection and sanitization in a variety of industries such as chemical processing and wastewater treatment due to its effectiveness and ease of use. However, it is considered a volatile organic compound (VOC) and is highly toxic and sometimes explosive if combined with other substances. Exposure to Cl2 can result in irritation of the eyes, mucous membrane, skin and respiratory system and can even result in death at higher levels. Considering the significant risks of Cl2, reliable detection equipment is vital in the case of an accidental release.

TAS has extensive knowledge of chlorine process emissions and storage and handling emissions for everything from bleach production to water sanitation. TAS brings a unique approach to projects by taking into consideration the full range of requirements for a project and clearly defining the scope such that all stakeholders are in agreement

Hydrogen Cyanide (HCN)

Hydrogen Cyanide (HCN) is a colorless and volatile liquid that converts to a flammable vapor slightly above room temperature. HCN is highly toxic and not only presents significant risks when inhaled but also can be absorbed through the skin in both its gaseous and liquid forms. Depending on the concentration, it can interfere with cellular oxidative processes which can lead to death by asphyxia. Industries utilize HCN in several ways as it is a valuable forerunner for the synthesis of various chemical compounds and is most commonly used in the extraction of mineral ores.
