Pressure measurement in the chemical process industries (CPI) is crucial to many unit operations, and selecting the most effective pressure sensors for a given situation can be complicated by a range of factors. An initial key to selection is establishing…
Raise your hand if you ever regretted going with the low cost bidder. Keep your hand raised if the low cost bidder ever yielded you the highest cost result. If your officemate is staring at you quizzically, pretend to be…
Combustion provides heat for many industrial processes and accounts for over 80% of the power used by turbines to generate electricity. Over the past several decades, regulatory action and concerns over environmental air pollutants, such as oxides of nitrogen (NOx),…
Many operations involving ideal gases are readily calculated using a basic knowledge of thermodynamics. Non-ideal gas behavior, however, can deviate significantly from that of ideal gases, and in some cases, large errors can be introduced in process calculations if a…
Wastewater streams from petroleum refineries present some of the largest ranges of variation in contaminant loadings and contain some of the toughest contaminant profiles to treat. These factors render the wastewater treatment processes difficult to control. The most challenging area…
Gas turbines are widely used throughout the chemical process industries (CPI) — especially in petroleum refineries and petrochemical facilities — to provide both mechanical-drive and power-generation capabilities. Presented below are a variety of recommendations related to the selection and arrangement…
Due to their simplicity of construction, lack of moving parts, ability to operate at a wide range of temperatures and pressures, low capital and operating cost, cyclones have been the workhorse for gas-solid separation in a wide variety of industries.…
