Testing in filtration processes is critical for determining the properties of solids being filtered and the ease or difficulty of the filtration. In addition, laboratory testing is important in specifying filter media, filter aids, filter area, cake space needed and…
Ethanol is widely produced by fermentation of sugars from agriculture feedstocks, such as corn and sugarcane. In order to meet growing energy requirements, several lines of research have focused on cellulosic ethanol production, where some type of lignocellulosic biomass, such…
A recent book by Lieberman [1] stresses that to combat the environmental crisis that our planet is facing, it is essential to make existing units work adequately and efficiently. Equipment that malfunctions or limps along limits production and does not…
Working in close proximity to the high pressures and temperatures commonly found in the chemical process industries (CPI) is cause enough for concern over a person’s wellbeing; but working in close proximity to chemicals that are considered toxic, hazardous or…
Milling is a mechanistically driven process that breaks solid material into smaller pieces. Selection of the optimal mill is a daunting task that often leaves engineers relying on vendor suggestions to decide which mill is right for their job. This…
Calculating volumes of solids in piles as they are poured into various shaped containers can be important information for solids-handling applications. The following set of equations represents guidance to help determine solids volume in these cases. Solids in containers Solids…
Avoid delays, cost overruns and more with significant owner involvement It is well known that the oil-and-gas, chemical and petrochemical industries are capital intensive. They require sophisticated facilities (plants), the installation of which are typically handled via capital projects…
Ethanol is a widely used commodity chemical with several applications, including use as a solvent and as a gasoline blendstock in the fuel market. Globally, the major portion of ethanol production is based on the fermentation of sugars from crop…
Optimizing fan performance can help plants reach overall process efficiency goals. The cost of powering fans and ventilators in the chemical process industries (CPI) is significant. For example, ventilation and air-pollution control systems can account for over a quarter of…
Chemical, pharmaceutical and related industries produce large amounts of wastewater in their production and cleaning processes. The wastewater characteristics are often diverse, and may include minimally biodegradable or toxic substances, or both. To protect the environment, these wastewaters typically must…
