Waste gas incinerators react oxygen with waste hydrocarbons at high temperature to produce a clean flue gas. A perfect incinerator would have a destruction and removal efficiency (DRE) of 100%, zero fuel usage and zero emission of carbon monoxide and nitrogen oxides. A small amount of the original hydrocarbons always remains, though. If 1% is left, the DRE is 99%. Some CO and NOx always are produced, too. However, NOx emissions are lower for a regenerative thermal oxidizer (RTO) than for almost any other type of thermal oxidizer. With the U.S. Environmental Protection Agency and local air boards requiring DRE values from 95% upward, effectively dealing with waste gas means ensuring compliance with the added benefit of reduced energy costs. In this Special Report we take a look at how an RTO often can offer an effective and fuel-efficient options for cutting the cost of waste gas incineration, how technologies transform greenhouse gas into a feedstock for chemicals, how the right emission control system can help meet compliance and reduce energy costs and several steps that play a crucial role for setting up an effective greenhouse gas monitoring plan.

According to a U.S. Department of Energy survey, steam accounts for one-third of all the energy used in process plants. Monitoring and optimizing the cost of your steam system can yield big rewards. Ignoring inefficient operation easily could drain profits.
Operating and maintaining a reliable steam system is vital to chemical processing plants and can have significant cost impact on a plant's annual budget. Typical profit drainers in operating and maintaining a steam system include excessive fuel cost, inefficient steam generation, less-than-optimal steam utlilization and poor condensate recovery. This Chemical Processing Steam eHandbook presents strategies for reducing cost associated with using and generating steam, a 4 step approach for improving efficiency and insight on heat exchanger selection criteria. Specifically:
- Control Steam System Energy Costs - Steam system losses can silently drain profits
- Optimize Your Steam System - A simple four-step approach can improve steam efficiency

Thermogravimetric analyzers (TGAs) deliver valuable information about a material’s response to temperature. But while the information they deliver is critical, TGAs themselves tend to be bulky and difficult to use, and can cost tens of thousands of dollars. This paper explores how you can gather the same data as a TGA using an instrument which is considerably easier to use, more durable, and less expensive: the Computrac MAX 5000XL. The materials examined in this paper are certain flue gas desulfurization byproducts—gypsum, calcium sulfite hemihydrate, and calcium hydroxide—but the principles in question can apply to all manner of materials, from biofuels to pet food to landfill waste.

Optical Dissolved Oxygen Measurement in Power and Boiler Applications
Over the past decade a few trends have started to gain pace within the industry, driving a change in instrumentation requirements for operations managers and plant chemists:
- Maintenance and operations budget cuts have resulted in fewer plant personnel, forcing plant staff to optimize their workload even further
- As the cost of building new power and boiler systems increase, many operators now look to plant life extensions as a solution to bridge gaps in production capacity at a lower investment premium
These trends have changed the requirements in these applications. Starting from these trends, this article analyzes the options for oxygen measurements that are precise, reliable, stable, and above all require low to zero maintenance.04/27/2015

Increasingly precise process control strategies, often linked to computer control, have accelerated the use of sophisticated on-line chemical composition analyzers in plant applications. Instruments such as gas and liquid chromatographs, ion chromatographs, laser optic instruments, atomic absorption instruments and specific ion analyzers, which were rarities in laboratories ten years ago, are now found routinely in plant settings.
While continuing miniaturization and “rugged-ization” of the electronics are making the instrumentation circuitry more tolerant of the plant environment, the level of contamination in plant samples compared to laboratory samples continues to plague the process. This white paper reviews the factors in plant operation that may affect the deliverability of acceptable samples and provides guidelines for addressing these factors.11/04/2014
In the decade before Stuxnet attacked process control systems in Iran, there were just five known supervisory control and data acquisition (SCADA) vulnerabilities for all control systems in the world, according to the U.S. Department of Homeland Security's Industrial Control Systems Cyber Emergency Response Team (ICS-CERT). In 2011, the year after Stuxnet, that vulnerability count jumped to more than 215. Last year, it reached 248. No surprise then that Chemical makers are increasingly focusing on protecting their process control systems from intrusion both from the inside and outside.

During industrial manufacturing, many companies use a wide variety of chemicals from methanol, acetone and benzene to foodstuffs like wine and edible oils stored in large tanks at different points in the manufacturing process. In a technique called “chemical tank blanketing,” or “padding” nitrogen is commonly applied to protect chemicals stored in tanks against contamination, degradation or chemical change as well as to prevent fire or explosions. This white paper first discusses blanketing basics and benefits. It reviews considerations for tank blanketing systems and discusses a newer approach, which is typically more cost effective for most applications, is that of generating nitrogen on-demand in the plant itself.09/12/2014
Research Paper: Investigating the Relationship between Gypsum Purity and Hydrogen Sulfide Production under Anaerobic Conditions
Calcium Sulfate (CaSO4) more commonly known as gypsum is a naturally occurring white crystalline mineral that has many different uses and applications. Gypsum in its hydrated form (CaSO4•2H2O) is used in the construction industry for fire resistance in buildings. Outside of the construction industry, gypsum is used in the food and fertilizer industry for calcium and sulfate fortification respectively. When gypsum is no longer usable, it is deposited in construction and demolition(C&D) landfills where anaerobic (low oxygen) conditions and the presence of sulfate-reducing bacteria promote the decomposition of wallboard/gypsum into hydrogen sulfide gas (H2S). Due to local and state regulations on odor control, these C&D sites monitor their fill for hydrogen sulfide gas. This paper will couple two methods of analysis to observe the relationship between the purity of gypsum (calcium sulfate dihydrate) and hydrogen sulfide concentration as a sample is fermented by sulfate-reducing agents (e.g. bacteria). The scope of this research may be beneficial for industrial hygienists concerned with C&D landfill H2S levels or for incoming gypsum processing plants who suspect poor quality gypsum.09/12/2014
