Critical Topics
Reducing energy consumption and your plant's environmental impact is a hot topic. Creative thinking in your energy efficiency projects will give you the competitive edge during these tough times.
Drive up energy efficiency
The constant-speed approach to AC motors made a lot of sense when energy was cheap and drives technology was in its infancy. With their latest advances, adjustable speed drives can provide one of the best energy efficiency options for a plant.
Consider Three Ways to Energy Efficiency
Now’s the time to make radical changes in funding energy projects
It’s time for a design check
Pay closer attention to energy efficiency and impose standards.
Special Report: Energy Efficiency
Reducing energy consumption and your plant’s 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.
Energy Savings Pick up Steam
More attention to steam systems and trap monitoring provides big benefits. At most chemical plants, plant management and operators face increasing pressures to improve the energy efficiency of their processes, so they should see how they can save on steam.
You can't manage what you can't measure. And what you don't measure will never improve. Enter plant optimization. Gathering data to improve operations offers a competitive advantage.

Chemical industry sees green
Developments target economics, not just environmental benefits. While pollution prevention was the original goal of green chemistry, today’s efforts promise to have a substantial economic impact.
Special Report: Chemical Industry Sees Green | Bio-Based Fuels and Feedstocks
For years the industry has been “talking green.” But what real strides have been made? Will a Presidential Executive Order compel the industry to speed up efforts to actually go green?
Defining "Green Chemicals"
As the Industrial Water Treatment Program Manager at the federal installation, I am interested in resorting to "green chemicals" in the chemically treating all the boilers, cooling towers and closed loop systems at this installation. Is there a clear definition of what constitutes "green chemicals?" Does that vary from state-to-state, region-to-region, and who has the final word on what is or isn't "green chemicals?"
Feedstock change is hot and poppin’
Corn, other renewable resources garner increasing interest and investment. Read here about the progress that is being made in discovering a new generation of feedstock.
Wastewater treatment is a critical process for chemical plants. Keeping on top of how to recycle and reuse will ensure you get the most of your water-treatment operations.
Act Before There’s Not a Drop to Drink
Ground water protection is the responsibility of everyone including the chemical industry. An energetic group of state and federal ground water agencies, industry, environmentalists and other stakeholders, however, has made it a key area of their focus. The Ground Water Protection Council (GWPC) is a nonprofit Section 501(c)(6) organization dedicated to promoting and ensuring the use of best management practices and “fair but effective” laws regarding comprehensive groundwater protection.

Better water technology is on tap
The drought in many parts of the U.S. so far this summer points out the preciousness of water supplies. There’s greater demand for waste-minimization and recycle-and-reuse technologies as well as more awareness of utility usage and the impact of life-cycle costs on water-treatment operations. Here’s a look at new technologies that will help.

Measurement of Oxygen Concentration in Blanketing and Inerting Operations
Gaseous oxygen measurement with amperometric sensors is the most direct and easiest solution for oxidation and explosion protection.
Unwelcome oxygen Tank blanketing is the process of filling the headspace in storage vessels and reactors with an inert gas to prevent its contents from exploding, degrading or polymerizing and to protect equipment from corrosion. A blanketing system is normally designed such that it operates under higher than atmospheric pressures, therefore preventing outside air from entering the vessel. As oxygen and moisture in the air can be undesired in numerous processes and applications, blanketing is done in a wide range of industries, varying from (petro)chemical to food and beverage, pharmaceutical to pure water.
Special Report: Prepare For The Economic Recovery
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.

Choosing the Right Emissions Control Option
Determining the most economical option to control airborne emissions during chemical process operations presents several unique challenges. As with any add-on control system, the goal is to minimize the annualized total costs while maintaining proper operation. In this white paper, learn the different options that are available and which ones fit your process the best.
Fluid Handling
Spray Gas Quench Design Considerations
The use of spray nozzles to rapidly cool or quench gas streams is an essential application in many industrial processes, such as chemical reaction vessels, incineration, and power plant absorber gas inlet. An optimized spray quench design requires engineering analysis of the operating environment, spray nozzle performance and process reliability. This technical paper describes the design considerations for spray gas quench systems such as nozzle selection, process control, system configuration and reliability. Application of this knowledge can result in a gas quench system that operates efficiently and reliably with reduced vessel size, reduced atomization energy consumption, and minimized downtime, to achieve capital and operational cost savings for your process.
Peristaltic Pumps: A Simple Solution for Abrasive and Corrosive Chemicals
Finding the right pump for metering abrasive and aggressive chemicals can be challenging. The pump of choice needs to withstand harsh chemicals, accurately meter, and be simple to maintain and operate. More and more process engineers are turning to peristaltic pumps to solve their pumping problems, reducing life cycle costs and driving gains in process efficiency.

Chemical Processing Special Report: Conveyors
No matter what industry you’re 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.

How Automated Water Jetting Improves Tube Bundle Cleaning Efficiency
Heat exchanger efficiency is a critical factor in processing productivity, and tube bundles must be kept clear of deposits to maintain that efficiency. Automated high-pressure water jetting systems, with flexible or rigid lances, remove deposits 75% to 90% faster than manual methods and are more operator-friendly.

Recent Pumps question...
Q:I have an application where the pump recirculation piping tie-in into the pump suction. If possible, I would like some best practices/guidelines to the following:
1. Temperature rise during circulation I have seen equations where calculations look at temperature increase when the pump is throttled. What is the calculation approach when the pump is in circulation to its suction? I have tried different approaches, e.g., one where I used the volume of the circuit and treated the calculation like heat input into a tank after a certain time period. The other approach is where I estimated the time a given molecule moves through the circuit before it enters the pump again. Both these approaches result in different times based on a given temperature rise. Please advise.
2. Also I would like to know guidelines/best practices on where to place the spillback return to the suction.
