In non-pressurized systems, various types of pumps can be used to induce liquid movement or flow. However, many of these pumps have limitations in both batch and continuous processes. Gravity pumps must be located below the fluid source and are typically not automated, limiting process configurability and ease of use. Peristaltic pumps induce pulsating flow, […]
In processes operating at extreme conditions, it can be a bit tricky to maintain reliable flow control. The combination of a Coriolis mass flow meter, dual valve pressure controller (PCD), and dome-loaded back pressure regulator (BPR) enables automated flow control under the following conditions: Systems flowing fluids that are aggressive or of unknown composition High […]
The tropospheric air pollutant ozone poses serious risks to human health. It can damage the lungs, worsen chronic respiratory diseases, and increase susceptibility to respiratory infections. Unfortunately, due to continued emissions of its precursors from sources such as cars and industry, ozone concentrations are still considered unhealthy in many parts of the country. In order […]
This article was originally published in Fluid Handling Pro on June 29, 2021. Read the original article here. Bioreactor sparging systems are designed to introduce oxygen to feed cell cultures while removing carbon dioxide to prevent toxic buildup. Various bioreactor features and components are critical to optimizing these processes. Spargers, impellers, baffling, and bioreactor shape all […]
Finding the right instrument to measure or control non-Newtonian fluids can be a challenge. Some popular flow technologies like electromagnetic meters can exhibit up to a 20% deviation in accuracy when used for such fluids. Ultrasonic flow meters have also shown up to 15% deviation when used for non-Newtonian fluids transitioning between laminar and turbulent […]
CO2 is used in all kinds of industrial applications; for example, liquid CO2 is commonly used as a cooling agent and solid CO2 (dry ice) as a dairy preservative. Here, we focus on the industrial applications of supercritical CO2 (sCO2). What is sCO2? A supercritical fluid is one that exhibits both gas and liquid properties […]
Cowritten by Alicat; Mitchell Hsing, Ph.D., CEO & Co-Founder of Inchfab; and Parker Gould, Ph.D., CTO & Co-Founder of Inchfab Background: Nanoscale fabrication systems & Inchfab The increasing demand for computing power over the past 60+ years has led to exponential increases in both device complexity and production volumes. To keep up with this demand, […]
Aerated chocolate is increasingly popular because of its particular mouthfeel: bubbles in the chocolate make it lighter, with a unique texture. An aerated chocolate bar has more surface area than a standard chocolate bar, which is why it melts faster in your mouth, intensifying its taste. How are bubbles added to chocolate? The short answer: […]
Beer is the beverage of choice for billions of people around the world. Whether ale, lager, or stout, carbon dioxide sparging is the process by which beer gets carbonated – making it the not-so-subtle difference between a refreshing pint and a flat disappointment. The average beer drinker is like to have strong feelings about what […]
The growth of the IoT (Internet of Things) is driving the need for smaller and more ubiquitous sensors. Normally, one thinks of optical or electrical sensors in this context. This type of measurement has typically been in the province of automotive and process control industries and is largely unavailable at the consumer level. Presently, IoT […]
