While machine learning has been researched for decades, its use in applying artificial intelligence in industrial plants and asset operations and maintenance is now advancing exponentially. This is due to the growth in big data and the expansion of the Internet of Things (IoT); the ability to provide the processing power needed to analyze larger data sets; the availability of machine learning methods; and the need for superior predictive and prescriptive capabilities required to manage today’s complex assets. This provides the basis for machine learning to be applied across a variety of industrial challenges.
This white paper focuses on some of the principles within machine learning and those industries that are primed to take advantage of it to maximize the benefits it brings to improve situational intelligence, performance, and reliability. Download now.06/20/2018

Hydrodynamic bearings depend on a steady flow of lubricant onto the shaft, among other factors, in order to generate the film that separates the shaft and bearing during operation. In many applications, such as fans, motors, and gearboxes, oil rings are used to deliver this lubricant. However, there are limitations to oil ring lubrication, especially during startup, slow speed conditions, and in the presence of solid contamination. Adding an external circulating oil system can overcome these limitations while offering benefits to bearing reliability, providing cooling, and allowing for easier condition monitoring.06/11/2018
The problem with solids is that sometimes they don’t want to move. This often results in solids settling out of slurries. Many believe that to monitor solids reliably, they must use an expensive technology. Another problem is dust. Being sure you stay on top of housekeeping is a must. Lucky for you, there are several techniques that can make solids stop behaving so badly.
To help you secure solid success, Chemical Processing has put together an eHandbook. It includes insight on:
- Stop Struggling with Your Slurry -- Convert a settling solids suspension into a non-settling one.
- Make Sense of Ultrasonic Sensors -- Understand the relationship among equipment, materials and environment when selecting the appropriate technology.
- Consider an Industrial Central Vacuum System -- A fixed tubing network simplifies housekeeping, reduces equipment wear and eliminates trip hazards.
- Save Time on Viscosity Measurements -- The cone plate method makes the most of small sample sizes.
- Choose the Right Equipment -- Certain processing technologies can help increase a powder’s flow capabilities.
Thermal fluids have the potential to directly affect the safety, maintenance, efficiency and reliability of overall plant operations.

The drive by some chemical companies to improve energy efficiency extends well beyond their production processes. Indeed, steam is a major focus and innovations in water-related energy efficiency are top of mind. But great care must also accompany the pursuit of efficiency. Engineers understand the role of insulation for heat conservation and freeze protection. But pipe installation on jackets, coils, reactors and heat exchangers is tricky.
To help you avoid costly and sometimes deadly steam mistakes, Chemical Processing has put together an eHandbook. It includes insight on:
- Energy Efficiency Soars -- Broad-ranging efforts are providing substantial savings.
- Provide Better Protection from Hot Pipes -- Use more conservative limits for insulation skin temperature.
- Keep Cool Designing Heat Exchanger Piping -- Consider these points when working with exchangers, coils and jackets.
Poorly designed and overly simplistic energy performance indicators often drive energy savings at the expense of product yield or quality. To identify opportunities for substantial reductions in energy consumption in your refining operations, look to modern simulation tools and optimization methods to enable investigating all the potential alternatives for distillation separation sequences and selecting the best sequences.
To help you with opportunities, Chemical Processing has put together an eHandbook. It includes insight on:
- Save Energy In Distillation -- Revamping may cut consumption considerably
- EMISs Evolve to See the Bigger Picture -- Adding process considerations improves energy savings and production performance.
- Consider Liquid Ring Technology for Dry Chlorine Compression -- Liquid ring compressors offer lower cost and other advantages for chlorine processing applications
Process Safety is not just an action or legal requirement, but a way of life and an inbred culture. In order for it to work effectively, many actions have to be performed and incorporated into a manufacturing process from conception to decommission. Most importantly it is a live process whereby when any change occurs, no matter how small, the affected operation must be reassessed to ensure that the safety of the process is not compromised.04/25/2018
Vacuum technology never stops developing, and for decades it has continued to progress.

Many processes require a device to control or limit the pressure that can build up due to an upset, instrument or equipment failure, or fire. Pressure relief valves, backflow preventers and rupture disks provide this protection.
However, most chemical processing plants have processing units originally designed and built prior to the availability of current reverse acting disc designs. Rupture disc designs have evolved greatly in the past 80 years to satisfy the greater demands of OSHA for improved safety devices, the EPA to minimize potential fugitive emissions, and the needs of process industries to improve efficiency and mechanical integrity
This report sponsored by Continental Disc takes a look at how manufacturers are improving efficiency, performance and mechanical integrity.

Powder handling can be dangerous and unpredictable. Indeed, many processes generate dust, which can lead to explosions. Preventing the generation of dust is easier, cheaper and more reliable. This eHandbook offers a few preventative measures. Another problem with powder handling and solids is you often have to pray you don’t have flow issues. In most cases, clumping is the culprit. This eHandbook highlights 10 causes of clumping and 10 solutions. And yet another concern is physically moving the solids. Inside is a top 10 list that addresses pneumatic conveyor systems and lists tips for planning and modifying existing ones.
To help you properly handle dangerous and unpredictable powders, Chemical Processing has put together an eHandbook. It includes insight on:
- Deftly Deal with Dust -- Minimize generation and consider either collection or suppression
- Clamp Down on Clumping -- First understand what’s really causing the problem
- Install Pneumatic Conveyors Correctly -- Follow 10 steps to prevent a variety of common problems
Selecting the right vacuum technology for chemical and pharmaceutical processing applications is often difficult. A vacuum system must deliver the required pumping speed and ensure the required pump-down time. It cannot be sensitive to process gases and must meet all requirements. Reliability and economic efficiency also play a significant role.02/06/2018
