Pressure Vessel Tank

Pressure vessels and towers are common equipment in the chemical, petroleum, and natural gas industries, used to store, process, and transport various fluids (gases, liquids). The following is a brief introduction to them:

Pressure vessel
Definition:
A pressure vessel is a closed device that can withstand internal or external pressure and is used to store or process gases, liquids, and gas-liquid mixtures.
Classification:
1. By pressure:
Low-pressure vessel (0.1 MPa ≤ P < 1.6 MPa)
Medium-pressure vessel (1.6 MPa ≤ P < 10 MPa)
High-pressure vessel (10 MPa ≤ P < 100 MPa)
Ultra-high-pressure vessel (P ≥ 100 MPa)
2. By purpose:
Storage container: such as gas storage tanks, and oil storage tanks.
Reaction container: such as reactors, and polymerization reactors.
Heat exchange containers: such as heat exchangers, and condensers.
Separation container: such as separators, and filters.
Design standards:
The design must comply with relevant standards, such as ASME, PED, GB150, etc., to ensure safety and reliability.

Tower
Definition:
Towers are upright equipment used for mass transfer, heat transfer, and chemical reactions, commonly used in distillation, absorption, extraction and other processes.
Classification:
1. By purpose:
Distillation tower: used to separate liquid mixtures, such as distillation towers and extraction towers.
Absorption tower: used for gas absorption, such as ammonia absorption towers and desulfurization towers.
Reaction tower: used for chemical reactions, such as catalytic cracking towers and synthesis towers.
2. By structure:
Plate towers: such as sieve plate towers and floating valve towers.
Packed towers: such as Raschig ring towers and Pall ring towers.
Design points:
Tower height and diameter: determined according to process requirements.
Tower internals: such as trays and packings, affect mass transfer efficiency.
Material selection: the corrosiveness of the medium and operating conditions need to be considered.

Differences between pressure vessels and towers
1. Function:
Pressure vessels are mainly used for storage and transportation.
Towers are mainly used for mass transfer, heat transfer, and reaction.
2. Structure:
Pressure vessels are mostly horizontal or vertical cylinders.
Towers are usually upright cylinders with complex internal structures.
3. Operating conditions:
Pressure vessels have diverse operating conditions and a wide pressure range.
Towers usually operate at lower pressures but with complex temperatures and media.
Application areas
Petrochemicals: such as crude oil distillation towers and reactors.
Natural gas processing: such as natural gas separators and absorption towers.
Pharmaceuticals: such as fermentation tanks and distillation towers.
Food processing: such as sterilization kettles and distillation towers.
Pressure vessels and towers are crucial in the chemical industry and related industries. They must be designed and used in strict compliance with standards to ensure safe and efficient operation.
