  • Advances in flashpoint testing: economic impact

    Flashpoint testing is one of the oldest methods of the ASTM D02 Committee on Petroleum Products and Lubricants, which was formed in 1904. The most prevalent standards are ASTM D56 (Tag Method), D92 (Cleveland Method), and D93 (Pensky-Martens Method). These classical techniques, commonly referred to as open-cup and closedcup methods, share a common principle: A test flame is lowered into the ...

  • Turning wood chips and sawdust into a valuable solid fuel

    RUF briquetting units are the economical solution for the processing of wood chips and sawdust. Where timber is planed, turned and sanded, manufacturers end up with large quantities of wood chips and sawdust. By briquetting this material, you can recover a valuable solid fuel. Where large quantities are produced, the single briquette pressing system developed by RUF GmbH is the most economical ...

  • Impact of IT on river modeling

    Background Models of river channels and river flows have been used to good effect for many years. HR Wallingford Group, in the UK, has been building physical models of rivers for nearly 60 years. Some years ago, it was predicted that physical modeling would soon cease to exist, to be entirely replaced by computer models. This has not happened - in fact, the demand for physical models is greater ...
