Thinking like Sherlock Holmes for process filtration technology selection

CHEMICAL TECHNOLOGY

Sherlock Holmes and Dr John Watson are fictional characters of Sir Arthur Conan Doyle. Process engineers who live in the real world can learn many things from the two of them for solving process filtration problems. This article will intertwine the detective techniques (mindfulness, astute observation, logical deduction and others) of Holmes and Watson with the problem-solving skills required to select process filtration systems.

Recycling of resources in steel production

recovery

The slag formed during stainless steel production contains valuable raw materials which should preferably be fed back to the melt or intelligently reused. With a treatment plant at Outokumpu Nirosta in Krefeld/Germany ThyssenKrupp MillServices & Systems GmbH (TKMSS) has demonstrated that dry treatment of slag is significantly more economical and environmentally friendly than wet treatment. The central element of the plant technology is impact crushing.

Framework for Selecting Solid-Liquid Filtration Technologies for Particle Fines Removal

Chemical Industry Digest

In the manufacturing of chemicals, petrochemicals, pharmaceuticals, etc., after the initial mixing-reactions, there is always the necessity to remove the mother liquor from the process slurry. In some cases, the liquid is the valuable component, some cases it is the solids and in other cases it is both compounds. The nature of the requirements determines the type of equipment needed for the separation process. This paper provides an overview of separation equipment and then continues with a detailed view of technologies that can remove – recover small particle fines.
