The HUAYI Ethane Water Bath Vaporizer and Condenser is an integrated heat exchange package designed for ethane recovery and gas processing applications. The system combines a water bath vaporizer for controlled ethane vaporization with a matched condenser for process cooling and condensation.
The vaporizer uses circulating hot water as the heating medium, with ethane flowing through the tube side. The equipment is engineered according to project-specific process conditions, including operating pressure, temperature, flow rate and required heat duty. It is suitable for applications involving low-temperature ethane processing where reliable heating, vaporization and condensation are required.
The Ethane Water Bath Vaporizer and Condenser is an integrated heat exchange package designed for ethane recovery and gas processing applications. The package consists of a water bath ethane vaporizer and a matched condenser, providing controlled heating, vaporization, cooling and condensation according to the process requirements.
Designed for low-temperature, high-pressure ethane service, the vaporizer adopts a shell-and-tube heat exchange configuration with ethane on the tube side and circulating hot water on the shell side. The indirect hot-water heating arrangement provides controlled and uniform heat transfer while maintaining physical separation between the process medium and the heating medium.
The equipment can be engineered according to project-specific flow rate, pressure, temperature, heat duty, material requirements and site conditions, making it suitable for oilfield associated gas processing, ethane recovery and related natural gas processing applications.
A typical package includes:
1 set Ethane Water Bath Vaporizer
1 set Matched Condenser
Interconnecting piping within the agreed supply scope
Supporting structures and fixing brackets
Temperature and pressure monitoring instruments as specified
Sealing components and installation accessories
The final scope of supply can be configured according to the approved technical proposal and specific project requirements.

Note: The above technical data represents a reference configuration. Final processing capacity, heat duty, design pressure, design temperature, materials, dimensions, connections, instrumentation and other technical parameters shall be determined according to the actual process conditions and project requirements.
The vaporizer is designed for ethane service with a reference design temperature down to -100°C. Materials and pressure-containing components are selected according to the specified design conditions and applicable project requirements.
The shell-and-tube configuration provides effective heat transfer between the ethane process medium and circulating hot water while keeping the two media physically separated. Under the reference operating conditions, the ethane temperature increases from -88°C at the inlet to 5°C at the outlet.
The tube side is designed for a reference pressure of 3.0 MPa(g), compared with an actual reference inlet operating pressure of 2.2 MPa(g). Mechanical design and equipment configuration are determined according to the specified pressure and temperature conditions.
The water bath vaporizer uses circulating hot water for indirect heating, providing controlled heat transfer to the ethane process medium and reducing the risk of localized overheating associated with direct heating methods.
The vaporizer and condenser are supplied as a matched process package according to the required operating conditions. This facilitates system integration and reduces the need for separate equipment matching during project engineering.
Pressure-containing components are subject to applicable manufacturing inspection and testing procedures before delivery. Hydrostatic and leak-tightness testing can be performed according to the approved technical requirements and applicable inspection standards.
