Unlike time-consuming conventional methods, this approach to designing a dissolved air flotation (DAF) plant requires only the physical characteristics of the flocs — their size and density, flowrate and temperature.
Physical property values are essential for many chemical engineering tasks. This article reviews sources of physical property data, discusses the use of experimental methods to measure properties, and details several types of estimation techniques.
The patent process can be a costly journey down a long and winding road. An invention disclosure serves as a roadmap for preparing the patent application and ultimately obtaining a valid, enforceable patent.
Transforming the performance maps to a reduced coordinate system that is independent of suction conditions and rotational speeds allows these curves to be accurately incorporated into a process simulator.
The challenges of vaccine development are not limited to identification of suitable antigens, adjuvants and delivery methods, but include regulatory, technical and manufacturing hurdles in translating a vaccine candidate to the clinic.
By incorporating the batch standards S88 and S95 into the entire product lifecycle, companies can optimize their processes and project management. This enables them to rapidly get their products to market — a critical factor in staying competitive.
Fieldbus technologies have become increasingly popular in process control applications. This article highlights the practical applications and economics of various buses, so that an engineer can choose the best one for his or her process.
To function properly at optimum capacity and efficiency, multi-pass trays must be designed so that the liquid and vapor flows are properly balanced. This article provides guidance on how to achieve that.
Modular design principles are well known, but have found only niche applications in the Chemical industry. This article outlines an innovative methodology, whereby plant and process design may be conducted in parallel using components with pre-...
