Crude distillation unit (CDU) optimization

WHITE PAPER — Crude distillation unit (CDU) optimization The use of multi-channel on-line FT-NIR analyzer technology for the optimization of an atmospheric distillation unit CDU advanced process control is often implemented using a traditional chemical engineering approach through multiple control loops, heat/mass balances and pressure/ temperature/flow measurements. This white paper demonstrates the use and advantages of FT-NIR as a multi-stream, ...


Combustible Dust - Understanding NFPA 654

Combustible dust is a critical concern for any industry that processes and conveys dry bulk materials in their production facility. Changes in regulations have brought this issue into even greater focus. The National Fire Protection Association (NFPA) has issued stricter standards for safety measures used to prevent and mitigate explosions and fires in facilities where a ...


Computer models reduce need for real-world testing

Accurate simulations can replace many experiments and plant field tests Multi-scale and multi-physics models bridge science and engineering Open source software continues to make inroads As engineers and scientists strive to do more with less, computer modelling has become essential to cut costs, speed development and reduce uncertainty when designing everything from processes to molecules. Flowsheet simulators, a ...


Industry reduces its thirst for water (2/2)

Recycling – state of the art recycling is a good investment Enery and water management become one  Industrial water management will be one of three focal topics at ACHEMA 2015 on June 18th – 22nd in Frankfurt/M Membrane process: learning from Mother Nature The use of membranes in water treatment technology has been on the increase for many years. ...


Industry reduces its thirst for water (1/2)

Water management conserves resources and cuts cost Efficiency: Water management is also energy management Technology: Effluent-free production (zero liquid discharge) How well does industry manage water resources? The general tendency today is to take a holistic systems approach. More process water is being recirculated and industrial producers are recovering reusable substances and water treatment chemicals. Companies are also ...


The Character is Key- Challenges for Bulk Solids Technology

Characterization of bulk solids facilitates smooth production flows Nanoparticles pose a special challenge Bulk solids expertise needed for urban mining Roughly 50% or more of substances used in the chemical industry are solids which need to be processed, handled and transported, so it is hardly surprising that exhibitors and visitors at ACHEMA have an interest in bulk solids ...


Petroleum Refining Outlook

Increasing production of crude oil from shale deposits in the U.S. and oil sands in Canada offers North American petroleum refiners opportunities to access cost-advantaged feedstock. However, shifting product demand and hurdles in transportation logistics, along with technical issues associated with the properties of the crude from those areas, present challenges as refiners optimize their ...


Proppants Illustrate Environmental Permitting Issues for Dryers and Kilns

This article covers permitting and directly related design issues associated with thermal processes used for drying and calcining, using the production of ceramic proppants as an illustrative example. While the magnitude of permitting issues varies significantly with air-quality attainment area status, oxides of nitrogen (NOx), carbon monoxide and particulate matter are always the major issues. With proper design and operation, these emissions can be controlled at a reasonable cost. ...
