Faster. Smaller. Smarter. Modular. All express the future of process analytics. And un-stoppable describes the ongoing migration of process analytical instruments to continuous, online, field-mounted use at chemical plants.
Residue curve mapping is a powerful tool to better understand the design and operation of distillation columns. This article describes how to use residue curve maps to check the feasibility of separation of homogeneous mixtures and for developing the conceptual design of towers.
Since HART technology has been around for many years, most people feel that they know all that there is to know about it. The fact is the vast majority of HART applications utilize only a fraction of the full capability of HART.
The primary purpose of CO-LaN is to promote the use and the development of the CAPE-OPEN standards in Computer-Aided Process Engineering (CAPE) software, and more generally to encourage all actions aimed at facilitating the use of CAPE software tools in industry, government agencies and academia.

Distillation has always been a critical and costly step in the manufacture of products in the petroleum, chemical, and pharmaceutical industries. Fractionation Research reveals how companies can pool their efforts to obtain experimental distillation data.
Plant engineers who find it is difficult to get good level measurements have plenty of company. A recent poll shows that it is considered to be one of the two most vexing problems by process automation professionals.
Pneumatic conveying has long been a popular choice for moving bulk materials. However, the technology hasn't been standing still, and this can influence the choice between several types of pneumatic systems.
Like the 20th Century’s Great Conflict, the first Fieldbus War never really ended. But what will the outcome be this time? This article from CONTROL makes an educated prediction on how the battle may turn out.
A reader has a level measurement problem with a differential pressure level transmitter. The transmitter does not track the level properly. Check out the question and the in-depth answer in this contribution from ControlGlobal.com.
