Vessels in the pharma industry, are mainly used as a storage medium for liquid materials such as treated water and liquid chemicals. The vessels are used in almost all dosage formats because water, the primary raw material, is used in all departments of the pharma industry. Additionally, nearly all dosage forms have some liquid chemical composition in their formulation.
There are different capacities of vessels in the pharma industry, which depend on the product type and processes involved.
What are Vessels?
Vessels are large containers for storing liquid in the pharma industry, used during various manufacturing processes. During storage, they provide specialized features necessary for a specific liquid type.
Commonly, vessels are made up of metals that are safe for the product being used and prevent contamination or product degradation. Commonly, product contact parts are made up of SS316L, and non-product contact parts are made up of SS304.
They are equipped with various accessories to monitor the liquid inside them. These accessories help monitor critical liquid parameters, which are necessary during routine operation. If these accessories are not provided, it will become difficult to monitor the current state of a liquid, prevent damage to the product, or become hazardous for humans, the area, the environment, or other instruments or machines. These accessories also help safety in processes, in cases the liquid is explosive and subsequently saving it.
Types of vessels
There are different types of vessels used in the pharma industry, the selection of which depends on the manufacturing process and product types. An important point is to know your requirements and select the required one.
Some vessel types used in the pharma industry include the following.
Storage Vessels
Storage vessels are used for storing liquid in them. Commonly, they are used at
· Initial phase of manufacturing to store liquid raw material or treated water for manufacturing a product
· Intermediate stage, where a manufactured product ready for filling is stored until filing starts or completes
Since they store pharma-grade liquid or finished products, their material must meet ASME–BPE standards. If this standard is not implemented, the metallic body of a vessel will contaminate the product due to corrosion and material degradation. Also, chances are that non-standard metals will react with the product, changing its properties and making it dangerous for human consumption.
They are designed to be used at normal atmospheric pressure and must not be used for high-pressure applications. Otherwise, the vessel will leak, wasting the product and can become hazardous for the surroundings.
Pressure Vessels
Pressure vessels are also ordinary storage vessels, but their design makes them ideal for high-pressure applications. In it, the wall of the vessel is strong enough to bear high pressure and is enforced by solid materials so that it does not explode or rupture during operations.
Every pressure vessel has a design limit for specific rated pressure. The actual process pressure must not exceed the rated pressure. Otherwise, it will explode and become hazardous for the area, personnel, environment, and other instruments & machines.
Among other accessories, pressure vessels are supplied with safety valves. Its primary function is to release fluid if its pressure exceeds the set value on the safety valve, which is adjusted according to the maximum limit of the vessel. It prevents damage to the ship if pressure accidentally becomes more significant than the rated value of the pressure vessel.
Manufacturing Vessels
Manufacturing vessels are the types used in manufacturing a pharma product. They contain all the necessary accessories required during the manufacturing process. Some of them include the following.
Mixers: Mixers are mechanical parts that mix different chemicals with any liquid or water. It rotates in a speed set during the manufacturing process. The specific rate depends on the product type and manufacturing operation.
