Steam Vaporizer – Water Bath Type
DSW’s water bath vaporizers handle large capacity ranges for petrochemical and cryogenic plants. They vaporize liquefied gases such as oxygen, nitrogen, argon, ethylene, propylene, and liquid natural gas (LNG). These water bath vaporizers manage load ranges from 500 Nm³/h to 195,000 Nm³/h and can process up to three gas streams in one unit.
Design and Operation
A steam heating vaporizer efficiently vaporizes liquefied gases like LNG using indirect steam heating. Each unit features a round water vessel with an overflow nozzle and a submerged coiled tube bundle. Steam lances heat the water directly, and temperature controllers regulate it precisely. During standby, a miniature steam lance keeps the water at 60°C. Water circulation uses buoyancy and gravity, reaching total capacity in two minutes. Coiled tubes are welded into a ring pipe that distributes liquid and collects gas, promoting efficient water flow. This layout minimizes material stress, supports rapid load and temperature changes, and allows easy tube bundle removal for cleaning and inspection, enhancing maintenance efficiency.
Key Features
- Capacity Range: Operates from 500 Nm³/h to 195,000 Nm³/h.
- Multi-Stream Capability: Can handle up to three different liquefied gases simultaneously.
- Quick Response Time: Capable of ramping up to full capacity in two minutes.
- Efficient Design: The wound tube bundle design minimizes material stress and supports quick load and temperature adjustments.
- Maintenance Access: Removable tube bundles for easy cleaning and inspection.
- Noise and Erosion Control: An optimized steam injection system prevents steam hammering and erosion and minimizes noise emissions.
- Optional Enhancements: Additional water circulating pumps for faster availability (less than 10 seconds) and alternative heating sources like warm water or electrical heaters can be integrated upon request.
Applications
Water bath vaporizers or shell and tube vaporizers are essential in petrochemical and cryogenic plants for the vaporization of:
- Oxygen
- Nitrogen
- Argon
- Ethylene
- Propylene
- Natural Gas
With advanced steam heating systems and robust design, DSW’s water bath vaporizers ensure operational excellence and longevity. The ability to handle multiple gas streams and the optional enhancements for faster availability make these vaporizers a versatile solution for industrial applications.
