When automating fluid handling processes, it is critical to ensure that you are using the best type of pump for the process, and to understand how to control the type of pump you are using. The two major classes of process pumps — centrifugal and rotary positive displacement — require completely different control techniques. It is important to understand each pump type’s limitations, and...

Typical wastewater-treatment plants (WWTP) — both industrial and municipal — consume large amounts of energy, which can represent 50% or more of the facility’s variable operating and maintenance costs. Most employ biological processes that rely on energy-intensive aeration systems whose energy consumption is approximately 0.5 kWh per m3 of effluent treated. This article discusses a...

Thermal mass flowmeters provide advantages over other options for metering the consumption of natural gas by individual combustion units throughout the facilityWith today’s increased emphasis on strategic energy management, many throughout the chemical process industries (CPI) and elsewhere are attempting to obtain better information on the natural gas consumption in their facilities. While...

Most engineers know what viscosity is, but may have trouble explaining it. To be brief, viscosity is resistance to flow. For handlers of all materials that flow, either while being processed or in an end-use, it is important to think about the materials’ flow characteristics. The bottom line is to come up with ways to measure viscosity so that you can quantify whether a material will flow the way it...

When a flowmeter is needed, the selection process should include studying the characteristics of respective measurement technologies and analyzing the advantages/disadvantages for different plant environments. This effort will help ensure that a meter with the right performance and reliability, for a particular installation, is selected. Some of the most common industrial flowmeter designs are described...

The whole-product-lifecycle approach presented here encompasses more than basic selection Typical discussions of flowmeter selection address specifications, technologies, accuracies and performance, but there are many other steps that are not normally considered. This article focuses on these often overlooked criteria, which inevitably have far-reaching and costly implications over the life of the...

    According to experts in flow measurement, any chemical processors seeking to optimize its processes in an effort to offset the rising prices of natural gas, electricity and raw materials may want to look at improving measurement and control via the added capabilities of modern flow technologies. Increasing productivity and process optimization very often involves system automation, says Jens...

In many plants that batch-blend bulk products, weigh batching is a manual, time-consuming operation in which ingredients are weighed individually before being discharged to a blender or some other process vessel. A significant number of such plants could benefit from the installation of an automated weigh-batching system. For small as well as large operations, an automated weigh-batching system can pay for...
