If you were to ask chemical processors what they’re looking for from their screening equipment, it’s likely that the answers would be as varied as the chemicals they produce because screening requirements are entirely dependent upon the material being screened. However, equipment providers say that no matter the application, minimal downtime and maintenance costs and the ability to get more...

Limited budgets and the need for high performing operations are causing chemical processors and petroleum and gas refiners to seek out the best bang for their capital dollar. And when it comes to gas processing operations, such as carbon-dioxide removal, hydrogen purification and air separation, experts say today’s membrane technologies compare favorably to other available systems and will continue...

Production of natural gas from shale formations presents key water management challenges. As the number of gas drilling operations continues to grow in shale plays around the world, and the practice of hydraulic fracturing (frac or fracing) of gas wells remains widespread, efficient water use strategies are becoming critical aspects of shale gas operations. Fresh water supplies for drilling and fracturing...

Like the ammonia plants that feed them, urea plants are getting bigger. These large-scale plants are being built to not only meet the increasing demand for fertilizer — projected to grow steadily at 3.7%/yr — but also to take advantage of economies of scale. In the last ten years, the market interest has moved toward large fertilizer complexes producing 5,000 metric tons per day (m.t./d) and...

Many chemical processes in the U.S. that use centrifuges were established between the 1950s and the 1980s. As a result, most of these machines employ technology that was outdated literally generations ago. In addition, many processes have changed since installation, and doing more with less is now a key method of survival in today’s global economy. At the same time, regulatory and environmental...

  Because the benefits are many, roles for simulation software tools exist from planning and design of facilities through operations and everything in between. And thanks to enhancements, it’s becoming easier to use simulation alongside other software packages, while niche simulation tools are making complex processes easier and less expensive to implement. In general, process simulation...

Significant demand persists within the chemical process industries (CPI) for those with engineering backgrounds and technical skills. Companies across many CPI sectors are finding it difficult to find enough individuals with chemical and engineering skills and expertise to staff their operations. But despite strong demand for technical skills, recruitment of chemical engineers is somewhat constrained by a...

One of the biggest issues related to dust collection is compliance with U.S. Occupational Safety Health Administration (OSHA) and U.S. Environmental Protection Agency (EPA) regulations regarding combustible dusts and air quality. And as both agencies up the ante with tighter regulations and more scrutinizing inspections, it is imperative that processors make sure their facilities are meeting the standards...

When it comes to fixed gas-detection devices, there are a lot of choices available. And, wise chemical processors do not select this essential safety equipment based on price. Instead, for areas of the plant that require continuous monitoring for loss prevention and personnel protection, fixed gas-detection systems are chosen based upon reliability, flexibility and maintainability.   Figure 1...

Mobility as a “megatrend” has recently become the latest buzz-word, and synthetic rubber producers are boosting production capacities to meet the anticipated demand for more tires. At the same time, high fuel prices and increasing concern for the environment are driving innovations in rubber to make tires more fuel-efficient (see box on p. 19). Meanwhile, efforts to find more efficient ways to...

For years it has been the common practice to treat process water with various chemistries to prevent scale, corrosion and microbiologicals. However, as regulatory issues tighten, water scarcity becomes a growing concern and the cost of treatment chemicals increases, chemical processors are finding that stringent treatment chemicals are not the only answer. Instead, they’re relying upon a multi-prong...

The realization that our natural resources are not endless, and that we need to focus on sustainability is driving technology and its supporting funds toward new choices. In the chemical process industries (CPI), engineers are looking for alternatives to the traditional fossil-fuel-based chemistries, and are developing innovative bio-based routes to meet our needs. There is much evidence of this shift to a...

For years, clay has been the go-to product for spill containment simply because it was cheap and did the job. While clay, also referred to as diatomaceous earth, sand or kitty litter, will always have a place in in spill containment, if it’s the only product being used to clean up hazardous and other spills, it could be costing your facility more than you realize. With more modern options available...
