From Batch to Continuous Processing

Small chemical reactors offer a number of benefits compared to large reactors, such as better heat transfer and mixing. While small batch vessels are impractical at the industrial scale, continuous flow reactors can provide the benefits of small physical size…

A smart flange system for increased safety

The QVF Supra-Line is compatible with two proven flange systems — the QVF/WPR2002 and the Schott/KF systems — and thus reduces the number of technically equivalent components required while providing the user with increased safety. The Supra-Line extends the allowable…

This concentrate pump operates with steam, air or more

The new Pivotrol PTF4 is a high-capacity, pressure-powered condensate pump that covers a wider motive-pressure range. This new version can be operated by steam, air or other pressurized gases, and covers a complete pressure range of up to 200 psig.…

Reciprocating Compressors: Startup and Capacity Control Methods

There are two main reasons why compressor capacity regulation is used. The most prevalent reason is to adjust the suction flow to match the process demand. The second reason is to save energy. As a rule, capacity control is determined…
