By-product Gypsum
Published in Manjit Singh, Gypsum & Gypsum Products, 2023
Based on wet sieving of phosphogypsum through 300 micron sieve27-28, a pilot plant of capacity 3 tonnes per day has been designed and installed at CBRI for the beneficiation of phosphogypsum. The pilot plant is comprised of major equipment such as mixer, vibrating screen, rotary drier, ball valves and centrifugal pumps. The process flow diagram of the pilot plant is shown in Fig. 3.7. Various steps involved in the beneficiation of phosphogypsum are listed below: Churning and MixingPumpingVibro ScreeningCentrifuging/Vacuum filteringRotary drying of wet phosphogypsum

From the pilot plant, data were collected to conceive scaling up and to perform technical and economic viability studies. The cost composition for a unit producing 10,000 tonnes of P(3HB) per year included 29% sugar, 20% other raw materials and chemicals, 27% equipment depreciation, 11% energy and 13% others. Steam consumption was initially considered high and attributed to the yet non-optimized pilot plant for energy employed to collect the data [11] apparently reviewed in further estimations [55]. Considering that polymer production was mostly affected by the price of sugar, studies estimated that P(3HB) would be produced at a cost less than US$ 3.00 kg−1, and that integrating polymer production to sugar mills would be the most cost-effective model, since the prices estimated were competitive. Figures made public initially estimated a total investment of US$ 38 million required for P(3HB) production integrated to sugar mills in Brazil for a producing capacity of 10,000 tonnes per year [55].
What Are the Product’s Characteristics?

When defining indicators, we need to know if these are metrics that can be measured in the production process. In order to do this, we need to ramp up the lab-made product to industrial quantities in production. The planning of the conditions on how to make the product from a lab scale to full size manufacturing is called scale-up. The R&D team will need to partner closely with operations to migrate from the lab to production. Scale-ups can be defined in two ways. One procedure will be to go in a single step from lab environments to industrial-sized equipment. The second form of scale-up may involve a two-step process. Step one is having a successful transfer from a lab scale to pilot plant. The second step is taking the learnings from the pilot scale to help make the product in the large capacity production plant. The pilot plant has the same equipment as the production plant; however, it is smaller in size and larger than the lab. This intermediate step has its advantages since it will not tie up precious production time to make trial runs and less trial test product may be wasted.

In the design of an industrial plant, one of the previous steps is to simulate the project on a pilot scale. The purpose of a pilot plant is to obtain information about a given physical or chemical process, determine whether that process is technically and economically viable, in addition to establish ideal operational parameters for the design and construction of the industrial plant (Himmelblau and Riggs 2017; Felder et al. 2018). According to Anchieta (2015), technological investment on the pilot scale offers advantages and lower risks, compared to laboratory equipment for studies of scale expansion, operating conditions, and process performance, generating data for a more complete and detailed analysis.
