Solvent and Chemical Batching

Industries universally rely on solvents, acids, and aggressive chemicals. Therefore, batching accuracy of these chemicals directly impacts product quality, safety, and profitability. Fluidyne’s 6730 Preset Batching System range is engineered specifically for these realities, delivering precise solvent and chemical batching without assumptions, approximations, or inferred calculations.

Unlike velocity-based technologies, solvent and chemical batching using oscillating piston positive displacement flowmeters measures actual volume transferred. Each batch is delivered based on real volumetric displacement, not estimated flow. This makes Fluidyne systems exceptionally reliable for applications where fluid properties vary, flow conditions fluctuate, or repeatability is critical.

FAQ’s

What is solvent and chemical batching?

Solvent and chemical batching is the controlled measurement and transfer of a predefined volume of chemicals or solvents into a process, vessel, or tanker. Accurate solvent and chemical batching ensures formulation consistency, process safety, and cost control. It relies on precise flow measurement and fast valve control to deliver exact batch quantities without overfilling or shortages.

Solvent and chemical batching systems are widely used in pharmaceutical, petrochemical, specialty chemical, bulk chemical, and manufacturing industries. They are essential wherever accurate formulation, controlled transfer, or sales batching of chemicals and solvents is required, including tanker loading and reactor charging applications.

Automated solvent and chemical batching improves accuracy, repeatability, and safety. It reduces manual intervention, minimizes product loss, and ensures consistent batch sizes. Automation also enables recipe control, faster operations, and better traceability, making it ideal for regulated and high-value chemical processes.

Yes, solvent and chemical batching systems can be configured to handle multiple chemicals. Each chemical line can have its own flowmeter and valve, all managed by a central batch controller. This allows sequential or parallel batching while maintaining individual batch accuracy for each chemical.

Solvent and chemical batching systems are highly customizable. They can be tailored for different chemicals, flow ranges, materials of construction, control philosophies, and communication protocols. This flexibility allows the system to match specific process requirements, safety standards, and industry regulations.
