This column is based on “Oxygen Production – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/oxygen-production-cost. Oxygen is a nonmetallic element and one of the most abundant elements on Earth’s surface. Under standard pressure and…
A methodology and examples for estimating equipment costs are presented Engineers have the responsibility to create projects having attractive returns on investment and to create economically sound designs — designs that produce high-quality, competitively priced products. This requires the technical…
DSD is a new design-of-experiments (DOE) technique that is expected to bring huge benefits when using a Six Sigma optimization strategy Statistical tools are deeply ingrained in the Six Sigma methodology to optimize processes and products during chemical process industries…
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…
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…
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…
The pitfalls in cost estimating that cause project overruns have been well known for decades, yet they continue to plague the CPI When I first started writing this article, I set out to summarize the mechanics of project cost estimation.…
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…
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…
