Calculating volumes of solids in piles as they are poured into various shaped containers can be important information for solids-handling applications. The following set of equations represents guidance to help determine solids volume in these cases. Solids in containers Solids fed through a nozzle into a cylindrical or rectangular silo normally form a partial cone of a complex shape when the material is...

The interior surfaces of your storage tanks are constantly at risk. You undoubtedly walk past a tank and do not give thought to what is happening on the inside, but that is because you trust the interior coating to protect not only the storage vessel, but also the product being stored from corrosion that might occur on the tank. Without a doubt, corrosion is the principal enemy of a storage vessel. It...

Agglomeration is the process of converting fine powder particles into larger particles by the introduction of external forces. Agglomeration is often desirable because the process yields a product that has a higher bulk density, contains less dust, and has improved flowability. Figure 1 shows samples of fine potash powder and powder that has been agglomerated.  Figure 1. Fine potash powder is one...

Storage of bulk materials in hoppers, bins and silos is ubiquitous in the chemical process industries (CPI), and so are the challenges that go along with it. Flow stoppage (bridging or arching), variability in mixture composition (de-mixing or segregation), erratic flow, uncontrolled flow (flooding), discharge-rate limitations and structural failures are not uncommon. While the impact of vessel geometry is...

Evaporation of moisture or volatile organic compounds (VOCs) from bulk solids usually takes place in two stages: one in which the drying rate is constant, and the second in which the rate decreases over time. Devolatilization during the first stage is rapid and can be readily accomplished in flash, spray, or fluidized bed dryers. In the second stage, however, the VOC or moisture removal rate is diffusion...

    Vessels for handling bulk solids, such as silos and bins, are frequently used to heat or cool bulk materials in cases where a slow rate of change or long residence time is required. Often, the temperature of a bulk-solids stream must be raised, for example to bring about a chemical reaction in a subsequent processing step. Alternatively, a reduction in temperature is sometimes needed, for...

    Modeling the behavior of bulk solids has been a longstanding challenge for researchers and practitioners alike. The differences between fluids, rigid solids and bulk solids can best be illustrated by their responses to applied stress. For instance, when an external stress is applied to a fluid, it is transmitted equally in all directions. The response of a rigid solid (such as a metal bar) to...

    There are a variety of reasons to consider the purchase of a new tank or silo1. As organizations grow, so does the need for increased storage capacity. Meanwhile, an old tank may become corroded or worn and require replacing. Once it's determined that a new tank is needed, there are a variety of choices to consider. Whatever the end purpose, the chemical process industries (CPI) require tanks...

    The need to transfer bulk-solids materials from the outlet of a bin or from a conveyor, to a process, truck, or another bin is ubiquitous throughout the chemical process industries (CPI). Transferring material using equipment designed to mechanically convey chemicals works quite well, especially for long distances; however, for short distances, it can be prohibitively expensive and...

Most chemical processes must produce products that are uniformly mixed. There have been many articles written about preventing particle segregation during bulk solids flow; and ensuring a mass flow pattern is a common suggestion. But mass flow alone is not necessarily the answer to all segregation problems that can occur in silos and tanks. We will focus on the two major mechanisms of segregation; namely...
