Everything about Pilot Plant totally explained
A
pilot plant is a small
chemical processing system which is operated to generate information about the behavior of the system for use in
design of larger facilities.
Pilot plants are used to reduce the
risk associated with construction of large process plants. They do this in two ways:
- They are substantially less expensive to build than full-scale plants. The business doesn't put as much capital at risk on a project that may be inefficient or unfeasible. Further, design changes can be made more cheaply at the pilot scale and kinks in the process can be worked out before the large plant is constructed.
- They provide valuable data for design of the full-scale plant. Scientific data about reactions, material properties, corrosiveness, for instance, may be available, but it's difficult to predict the behavior of a process of any complexity. Engineering data from other process may be available, but this data can not always be clearly applied to the process of interest. Designers use data from the pilot plant to refine their design of the production scale facility.
If a system is well defined and the engineering
parameters are known, pilot plants are not used. For instance, a business that wants to expand production capacity by building a new plant that does the same thing as an existing plant may choose to not use a pilot plant.
Additionally, advances in process
simulation on computers have increased the confidence of process designers and reduced the need for pilot plants. However, they're still used as even state-of-the-art simulation can't accurately predict the behavior of complex systems.
Pilot plant is a relative term in the sense that plants are typically smaller than production scale plants, but are built in a range of sizes. Some pilot plants are built in
laboratories using stock lab equipment. Others are constructed of fabricated metal on dedicated concrete slabs and cost millions of dollars.
After data is collected from operation of a pilot plant, a larger production scale facility may be built. Alternatively, a demonstration plant, which is bigger than a pilot plant, but smaller than commercial plant, may be built to demonstrate the commercial feasibility of the process. Businesses sometimes continue to operate the pilot plant in order to test ideas for new products, new feedstocks, or different operating conditions. Alternatively, they may be operated as production facilities, augmenting production from the main plant.
