A variety of performance problems can arise in distillation towers during startup. Many are caused by equipment, hardware or process conditions. Hardware issues may be related to instrumentation, tower internals or ancillaries. Instrumentation malfunctions are also common during startup and are predominantly related to liquid level indicators, online analysis of key components and in some cases...

A novel cold-dry process makes possible the utilization of fine form-factor silicon, such as granules and sand-like fines, in the production of high-purity polysilicon for solar photovoltaic cells and semiconductors, where such fine-grained material would normally have to be sent back up the supply chain rather than into the crucible. The patent-pending drying system, known as FlashDry, was developed by...

Recovery boilers, in which pulp and paper companies burn spent black liquor from the kraft pulping process to recover and recycle sodium and sulfur, are a bottleneck in many paper mills. The reason is that they operate at their upper limit of heat flux into the boiler tubes, thus preventing an increase in the mills’ output, explains John Blackburn, co-founder of Liquid Lignin Co. (LLC, Charleston...

In conventional hydrogen and ammonia plants, the final conversion of CO to H2 occurs across the low-temperature shift (LTS) catalyst. This makes the LTS catalyst one of the most important catalysts in the plant — even small changes in its performance will have a significant impact on operating costs, says Kristina Svennerberg, marketing manager, shift and synthesis catalysts at Haldor Topsøe...
