The VTA Testing Center located in the Jiangning District of Nanjing, independent of the VTA German headquarters testing center, is a comprehensive testing facility equipped with a variety of testing equipment. It is capable of conducting small and medium-scale tests, as well as providing distillation contract manufacturing services.
Through experimental testing, the following information can be obtained, including the achievable product quality, yields, and distillation parameters. This will provide a reliable experimental data foundation for the customer's new process development, optimization of operating conditions, enhancement of process efficiency, and design of future facilities.
The results from the small-scale and pilot tests can also serve as the basis for the process parameters of the distillation contract manufacturing.
To ensure the protection of our clients' confidentiality, VTA guarantees strict confidentiality of sensitive product information. Information collected from clients is treated as confidential and strictly protected. As required, since this process may involve equipment production information independently developed by VTA, VTA may also need to keep this information confidential from the client.
Laboratory Pilot Test:
Theoretical calculations are often insufficient for designing industrial equipment or determining distillation process conditions. The results of experimental testing form the basis for the entire process and equipment selection. Sample testing and analysis can be conducted at the VTA laboratory. Additionally, customers will also receive samples of light and heavy fractions for analysis in their own laboratories.
At the VTA laboratory distillation equipment, customers can prepare as little as 1 kilogram of raw materials for preliminary feasibility studies. Distillation experiments are conducted on high-boiling, high-melting, and high-viscosity materials under low operating pressures.
Purpose of the preliminary test:
Determination of Process Parameters
Establish conditions for achievable product quality and yield
Production of small batch samples
Confirm the process parameters required for the distillation unit.
Confirm the feasibility of the experiment
Approximately 1-3 kg of raw materials required.
During the distillation process, observe the product's characteristics (such as foaming, coking, etc.).
Pilot Test - Film Evaporation and Short Path Distillation:
VTA has pilot-scale刮膜蒸发器 membrane evaporators, film evaporators, and short-path distillation equipment. Additionally, it offers film distillation units capable of separating close-boiling point mixtures.
Pilot testing involves verifying and enhancing laboratory test results under production conditions. Based on these tests, achievable production capabilities are obtained, and product quality and yield for future industrial equipment are determined and guaranteed.
Samples can be tested and analyzed in the VTA lab. Customers will also receive samples of light fractions and heavy fractions for analysis in their own lab. Distillation experiments are conducted under low operating pressures for high boiling point, high melting point, and high viscosity materials.
Pilot Test Purpose:
Determination of process parameters
Confirm the achievable quality and yield of the product
Design parameters for a distillation system tailored for the future
Bulk production of samples up to several tons
Dimensional design of process equipment and integration of industrial equipment
Film Coating System Selection
Verification of experimental test results under actual production conditions
During the distillation process, observe the product's characteristics (such as foaming, coking, etc.).
Distilled Contract Manufacturing:
Customers choosing VTA Distillation Systems for contract distillation will enjoy the following benefits:
Expand their own production capacity limitations
New product development for market expansion
Save clients the investment in their own distillation equipment
Gather new product production technology
Enhance the quality of existing products in the market
New products can continue the production of the old product on the customer's own equipment.
Control the production cost of new products
No need to establish your own production facility
Analysis:
VTA's testing center and distillation contract manufacturing system are equipped with a central analysis department. During the pilot and scale-up testing phases, professional analytical testers analyze and monitor product quality. Feedback from the analysis results helps identify optimal experimental conditions. The central analysis department analyzes raw materials and products post-distillation, controls the distillation contract manufacturing process, and all activities are documented in files.
This method enables VTA to obtain a comprehensive experimental record database, which can be used to evaluate products and processes.
