Sieving molecules

Adsorption and molecular sieve technologies have been widely used throughout various processing industries for decades to separate hydrocarbons or dry gases. Automation, including switching valve selection has an important role to play in the successful and sustainable molecular sieve adsorption process, often critical for the whole process plant availability.

Controlling your flotation process

Flotation is an important part of mineral processing in most mining operations, requiring an accurate, durable, and repeatable level control valve to manage level control in the column, cell, staged reactor, or direct reactor. The head pressure to the control valve from each type of flotation process makes sizing a critical function to ensure proper operation of the valve and performance of the solution. For instance, flotation cells have very low driving head pressure to the valve. Since the head pressure is so low, inlet velocities, outlet velocities, and any bends or elbows in the piping can affect this low head pressure. If all factors are not considered carefully in this case, the danger is mis-sizing the level control valve on the low side.
