Feedstock characterization, process testing and selection of operating conditions to support scale-up and design

Before developing an industrial plant, it is necessary to determine the composition of the starting material, its processing behavior and the possibility of obtaining the required process streams. Laboratory research allows you to check individual stages of the process and reduce uncertainty when choosing equipment.
The scope of work is determined by the specific task and may include the study of samples, laboratory experiments, comparative tests, selection of operating conditions, pilot testing and preparation of recommendations for further engineering.
Generating the data needed to select a treatment method
Assessing the applicability of the selected process to a specific material
Comparison of process options using test results
Determination of permissible temperature, time and other process parameters
Assessment of the feasibility of obtaining separate liquid, solid and gas streams
Analysis of samples after the selected treatment
Generating design inputs for pilot or industrial equipment
Verification of critical stages before deciding on plant design
Tests are performed on samples representative of the customer's material
Critical processes can be investigated before a full production line is formed
Operating conditions and process sequences are compared before selecting a baseline solution
Equipment functions are determined taking into account the behavior of the real product
Defines the parameters that need to be measured and controlled in an industrial installation
Laboratory data are used to develop the scale-up test program
Preliminary testing allows technology limitations to be identified before equipment is manufactured
Test steps, operating conditions and observations are documented within the agreed scope
The scope of the research is determined by the type of material, the required treatment outcome, the available sample volume and the stage of development of the project.
The sequence and scope of the stages depends on the material being studied and the task at hand. Not all tests require the same sequence and scope of work.
Test results depend on how representative the sample is of the actual process stream. Before starting work, it is necessary to determine the origin of the material, the sampling, storage and transport conditions.
If the composition is heterogeneous, multiple samples or a composite sample may be required. The required mass or volume is determined by the test program and available laboratory equipment.
Before process testing, material characteristics that may influence the selected process are determined. The list of indicators is formed individually and depends on the type of raw material and the required result.
Some measurements can be performed in-house, and specialized analyses can, if necessary, be transferred to specialized laboratories.
Laboratory modeling reproduces a single process step or sequence of steps on a reduced scale. The goal is to verify the fundamental feasibility of the process and determine the factors influencing the result.
Tests can be performed in series with changes in temperature, time, mixing intensity, number of stages and other parameters. The set of variable factors is determined by the work program.
For multicomponent materials, the possibility of obtaining separate oil, water, solid or gas streams is being explored. The stability of the separation and the need for additional processing steps are assessed.
The results are used to select settling, filtration, separation, heating, reagent treatment or other validated processes.
Thermal tests determine the behavior of a product when heated, the ability to remove water and volatile components, and changes in the physical properties of the material.
Test temperatures are selected for the sample composition and safety requirements. If necessary, the study is carried out in several stages with gradual changes in conditions.
Filtration tests are used to evaluate the ability to remove mechanical and suspended impurities from liquid streams. The type of filter material and the number of stages are selected based on the results of experiments.
If necessary, additional sorption or combined post-treatment can be explored. The materials used and operating conditions are determined separately for each task.
For solid and paste-like materials, the possibility of removing moisture and residual volatile components is being investigated. The permissible heating modes, changes in the physical state and characteristics of the resulting residue are determined.
Tests evaluate the need for mixing, the method of feeding the material, the possibility of condensation of the removed components and the requirements for the future drying module.
Pilot testing is used when laboratory results alone are insufficient for industrial design. It uses a larger material volume and equipment that operates on the same principles as the proposed plant.
The tests assess process stability, stage throughput, control conditions and auxiliary-equipment requirements.
The transition from a laboratory experiment to an industrial installation requires consideration of heat and mass transfer, residence time, mixing method, feed continuity and other factors that change with scale-up.
Laboratory results inform the engineering design, but industrial performance requires scale-up calculations and further verification.
