Conventional methods used to transfer reactants from one vessel to another present a number of challenges. They often require special pump designs; compatible with the wide range of fluids which may be used. In addition, even small failures of seals, especially on the suction side of the pump, can result in leakage of air or other ambient vapours into the fluid stream. For high-quality synthesis reactions, such impurities can lead to product rejections.
Rotating equipment like pumps require ongoing maintenance and can be prone to failure, which can be very disruptive to chemical production operations.
Pressure transfer offers a reliable alternative
Pressure transfer using pure, dry inert gases like nitrogen offer a simpler and safer alternative to pumping. Pressure transfer does not require any rotating equipment and is therefore more reliable. The flow rate of liquid transfer can be regulated by controlling the gas flow rate and pressure.
Linde has a long-standing reputation for the successful development of pressure transfer systems.
