Surprising observations regarding flooding in the upper fractionation trays of an atmospheric crude-petroleum distillation column are investigated In industial distillation processes, flooding is an abnormal, but relatively common, process condition in which liquid accumulates in the column. The accumulation may…
This column is based on “HDPE Production via Slurry Loop Process – Cost Analysis,” published by Intratec. The report can be found at the following URL: www.intratec.us/analysis/hdpe-production-cost. High-density polyethylene (HDPE) is one of the three main types of polyethylene, and…
New technologies can provide competitive advantages compared to established processes, but significant effort is required to transition a promising concept into a commercial reality Many students study chemical engineering with the aspiration of someday inventing an innovative process that could…
The ideal gas law ( PV = nRT), relating molar volume of a gas to pressure and temperature, is predicated on two assumptions: 1) that the volume occupied by the gas molecules is negligible compared to the volume of the…
Reducing the total cost of ownership is paramount for manufacturers of dairy, food and beverage products. Using the new Aseptic Mixproof Valve (photo) instead of alternatives can deliver a total cost saving of up to 45% for manufacturers using aseptic…
The SAGE UMT (photo) is a wireless, hand-held steam-trap-testing solution that enables accurate, on-the-go testing of steam-trap performance. SAGE UMT leverages radio-frequency identification (RFID) technology to quickly locate and identify steam traps. Its piezoelectric acoustic and non-contact infrared (IR) temperature…
This company has extended its line of specialty air-operated double-diaphragm (AODD) pumps with the addition of the new V150 13-mm Velocity Series pump (photo). Featuring a unique detachable mounting foot, Velocity Series pumps can easily be reoriented into a vertical…
As E&C companies strive to develop Building Information Modeling (BIM) 6D models for the owners and operators of CPI facilities, strong efficiency gains benefit all parties Truly transformational change is upon the engineering and construction (E&C) industry, and some consider…
The recommended velocities for fluids’ transportation must be updated periodically to obtain the optimum value of the pipe diameter in the current economic conditions To arrive at the optimum diameters for pipes, the heuristic criteria of recommended velocity has been…
This methodology can be used not only for laminar flow, but also for the complete turbulent flow region In recent decades, the impact of energy costs on the transport of fluids has led to a significant reduction in fluid velocity…
