Reducing energy consumption and your plants environmental impact is a hot topic. In this Special Report we take a look at the organizational obstacles to avoid, how to enroll your employees in the quest, and the steps you need to take in order to manage your energy costs. We also delve in to practical energy efficient applications such as recovering exhaust heat in air conditioned facilities and the use of carbon synchronous belts.10/01/2008
Many industrial plants use dissolved air flotation to remove fats, oils and grease, and suspended solids from wastewater. Chemical additions are often kept higher than necessary to account for variations in influent water quality that are characteristic of industrial facilities. Continuous monitor04/02/2013
Bristol-Myers Squibb manually monitored dissolved oxygen (DO) periodically and ran aeration blowers more than necessary to guard against variable loading rates. After upgrading the system to use online DO monitoring operators now have continuous DO readings in the aeration tanks, substantially reducing energy and maintenance costs.08/12/2013
In recent years, TOC analysis has become accepted in the industry as the standard method and the only reliable online method used to determine contamination in waters, to control processes, to prevent product losses and to minimize waste. It is especially important to monitor this parameter in applications such as condensate return water, boiler/feed water, etc. In boiler/feed water and in industrial steam generating systems, carbonic acid corrosion of condensate lines is often a serious problem. Depending on the application type, analysis of only one parameter (e.g., TC) is generally not sufficient to make any useful process decisions. Multiple-parameter analysis (TOC, TC, TIC, VOC etc.), as carried out in the Hach BioTector B3500c analyzer, is proven to be more useful and always superior to single-parameter analysis in the industry.03/18/2014
Breakdown of organic wastes entering a wastewater treatment plant is accomplished by using a biomass or blend of beneficial microscopic organisms, bacteria, and solids. This converts the nonsettleable solids (dissolved and colloidal matter) into settleable solids, carbon dioxide, water, and energy. This paper reviews the most common stages for measuring and controlling dissolved oxygen in a wastewater treatment plant.05/13/2014
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
No matter what industry youre in, chances are you use some form of conveying. Whether it be pneumatic, flexible screw, aeromechanical or other, different conveyors are required to handle different products. But which conveyor is best suited for your operation? Despite the fact that conveyors have been around for almost a hundred years, this question still baffles many industries. In order to choose the right conveyor for your operations, you need to consider your conveyor's use - production, processing, packaging, and you need to consider your business objectives - improve operations? reduce labor?
In this special report, we look at the different types of conveyors, discuss the use of tubular bag conveyors, and provide 10 tips to prevent a variety of common problems that could occur with pneumatic conveyors.04/20/2009

The WirelessHART standard provides a robust wireless protocol for the full range of process measurement, control and asset management applications. Based on the proven and familiar HART protocol, it enables users to quickly and easily gain the benefits of wireless technology while maintaining compatibility with existing devices, tools and systems.11/16/2007
Compressed air systems are sometimes called the "4th Utility" due to their presence in almost all industrial processes and facilities. As US water consumption continues to increase, compressed air systems provide an opportunity for energy managers to reduce associated cooling water consumption and costs. In this white paper, we focus on the opportunity to reduce the water consumption of compressed air systems. Understanding the costs and the alternative types of cooling systems is an important first step. This white paper provides background on US water consumption in both the public and industrial sectors; it provides detail on industrial water consumption -- including industrial cooling water -- and its associated costs; it also details six different types of cooling systems available.02/14/2012
In the real world, sharing PCN data with external systems and accessing PCN systems from external sources is fast becoming a business necessity. This paper provides some generic guidelines for enabling secure connectivity between PCNs and external systems.09/16/2005
Batch process control security is becoming a critical concern for the process control domain, IT technology infrastructure and the business enterprise. This paper explores several key security concerns in batch control system architectures and methods for addressing these issues.05/11/2006
Batch manufacturing systems must maintain the status of equipment, including which are available, dirty, out of service, etc. In industries that enforce Good Manufacturing Practices (GMPs), additional status types and values for process equipment must be maintained. Rules associated with the equipment status can be complex and involve the equipment class, current equipment state and time in the current state. This paper covers the operator interface used to review the equipment status and the interlocking requirements between the recipe and batch phases based on multiple status types.06/13/2006
Plants across the world are increasingly having to make thedecision to implement wireless technology in their industrial facilities. The right decision enables an infrastructure that provides significant benefits from wire savings to improved operations. Wireless is a complex enabling technology that requires many considerations before broad deployment in an industrial facility.09/27/2007
Whether we are headed toward an economic rebound or continuing with the current economic downturn, specialty chemicals manufacturers should take steps now in order to get or keep a competitive edge. But what steps should specialty chemicals manufacturers take? This Special Report will discuss actionable strategies including: Reducing costs while maintaining quality and compliance; Committing not just to "lean manufacturing" but to "lean supply chain" strategies; Implementing "agile manufacturing" practices.12/01/2009
"Migration could be the biggest single issue facing automation end-users today," stresses a report from the ARC Advisory Group. ARC estimates that installed automation systems worth about $65 billion are reaching the end of their useful lives. Distributed control systems (DCSs) more than 20 years old will need replacement within the next ten years. In this Chemical Processing Special Report: Migration we cover:
- Updating process control systems – understanding the challenges and missteps to avoid
- Case Study: FMC Corporation – we look at the production processes, operational challenges and automated solutions this diversified global chemical company chose when migrating their DCS
- Case Study: PRALCA – control systems migration for a petrochemicals facility
- The business case for control systems migration - strategies for protecting investments, improving business results and reducing risks
While upgrading process control systems is vital to maintaining a plant’s performance, the migration process often brings confusion and frustration for customers. See how Honeywell keeps control systems running at the best possible performance throughout the migration process and into the future.08/29/2012

Patching process control system software to remove security vulnerabilities is fraught with risk. System issues can be the result of installing a patch, but a system is also vulnerable without patching. Fortunately, virtual patching can improve the process and raise the system’s security at the same time.09/21/2012
