The COVID-19 pandemic has been a challenge for everybody. As industrial production begins to ramp up, it is natural for executive and operations staff to look ahead. But, it is also critical for producers to track and control what could be left behind. Meeting federal and state regulations governing BOD/COD levels and pH in water and wastewater, and VOC and NOx/SOx levels in air emissions is still the expectation.
At Messer, we are committed to the responsible use of natural resources, the development of clean technologies and the replacement of harmful substances with eco-friendly alternatives.
Messer strives to minimize the environmental impact of its operations, and to deliver technologies and gases that help you, our customers, substantially reduce if not eliminate emissions. We offer easily retrofittable technologies with low capital expense that can help mitigate some of the difficulties you may have meeting permit requirements or environmental sustainability goals.
When we visit companies, we ask four questions to uncover issues and help producers identify and meet their environmental targets and objectives. The questions, followed by solutions, are:
1. Are you challenged with meeting your permit requirements for your waste water?
Messer offers the BIOX™ family of wastewater oxygenation systems and solutions, world-class gases and equipment to lower biochemical and chemical oxygen demand (BOD & COD) in wastewater. The BIOX systems help managers of chemical plants, municipalities, pulp & paper mills, food production plants and other industrial processes maintain the biochemical oxygen demand (BOD) and chemical oxygen demand (COD) of discharged wastewater within targeted conditions.
The new BIOX mobile unit enables operators of small- to medium-sized wastewater treatment plants to better manage peak loads and downtime during aeration and equipment maintenance.
2. Did you know that Messer offers a technology that can remove NOx from your flue gas up to 95 percent, and perhaps more?
Messer’s high-performance eNOx™ NOx removal apparatus and technology, is a low-temperature, ammonia-free, end-of-pipe retrofit that can remove 95+ percent of NOx regardless of load, concentration, particulates or the presence of SOx.
The eNOx technology removes NOx by adding a stream of ozone that reacts to become N2O5 (a highly soluble and reactive species of NOx). Air pollution control equipment -- dry/semi-dry scrubbers, wet scrubbers or wet electrostatic precipitators -- converts N2O5 to nitric acid (HNO3), minimizing emissions and leaving a salt or solution for waste treatment or recovery and reuse.
3. Did you know that you can avoid the environmental and safety challenges of mineral acids by switching to carbon dioxide for pH control?
Our NEUTRA™ Water Treatment Process is a safer, simpler and better way to control pH and scaling in tanks, ponds and process water. The NEUTRA process lowers the pH of water with pure carbon dioxide (CO2), not harsh and hazardous chemicals, and the benefits are game-changing when compared to traditional acids.
The process scales to fit applications of most any size. It prevents hyper-acidification, as it is self-buffering around neutral. Because the NEUTRA process produces carbonic acid by combining CO2 with water, there is reduced corrosiveness and increased safety for the employee. Operators controlling pH levels with the NEUTRA process also can reduce operating costs and avoid handling highly corrosive acids.4. Are you trying to recover or remove your VOCs to meet your air quality permits?
If you are, Messer has a VOC recovery system for you. Our state-of-the-art CRYOSOLV™ vapor emission control (VEC) system cryogenically controls volatile organic compound (VOC) emissions simply, efficiently and cost-effectively. Easy to install and operate, the CRYOSOLV system uses inert, environmentally safe liquid nitrogen (LIN) to cryogenically recover VOCs including hydrocarbons, halocarbons, alcohols, solvents, and volatile natural compounds.
The CRYOSOLV process involves zero chlorofluorocarbons (CFCs), generates no wastewater or secondary hazardous emissions and requires no ignition source, making it safe for potentially explosive atmospheres. You can even reclaim and repurpose both the gaseous nitrogen and the VOCs.
