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.

How do we make safety in our processes second nature? The concept of inherent safety goes beyond simply not having materials that potentially could damage the pipes, vessels and equipment that make up manufacturing facilities. We need to understand all the ways those materials can be involved in incidents that harm people, the environment and our facilities.
Without a thorough understanding of those scenarios and how they can occur, we can’t properly evaluate the risks posed by different technological approaches and effectively apply inherently safer technologies.
In this Chemical Processing Process Safety eHandbook, we delve in to what it means to embrace the concept of inherent safety and provide tips for safer processing including:
- A variety of strategies that can eliminate hazards from operations
- Improving alarm management – how adopting a pragmatic approach can achieve significant benefits
- A rational approach to combustible dust explosion protection

Effectively mixing liquids and solids to create an optimal slurry is one of the perpetual challenges in the chemical industry. This case study demonstrates how an eductor-based mixing system can effectively handle a wide range of materials, utilizing the least amount of floor space, energy and human resources to achieve an optimized process. In addition, the eductor mixing system offers increased efficiencies over a conventional system of mixing by allowing solutions and slurries to be made on demand – as opposed to pre-mixed in large holding tanks. Another important benefit is the system limits exposure to operators, and mitigates issues of delivering solid material in a large vapor space. The design flexibility of an educator-based mixing system offers a high level of customization.05/14/2013
Flexible Intermediate Bulk Containers (FIBCs) have found their niche in the worldwide transportation of powdered, flaked and granulated products. FIBCs are typically made of woven plastic with some type of liner insert and are often referred to as super sacks, big bags or bulk bags in industry. During filling and emptying of FIBCs there is a steady accumulation of static charge that can result in electrostatic discharges from the FIBC. This may in turn provide sufficient energy for ignition of combustible particulate solids or flammable vapors, not to mention unsettling shocks to nearby personnel. In this white paper we review the NFPA 654 Standard for the Prevention of Fire and Dust Explosions from Combustible Particulate Solids and the importance of why identifying the Minimum Ignition Energy (MIE) of your combustible dust or flammable vapor is a necessary component for selecting the correct FIBC Type for your application.
