Type 7110 Water Bath Desuperheater and Type 7140 Condensate Recovery System Used in Carbon Capture Technology

Project by SAMSON Netherlands with CarbonOrO

Objectives

CarbonOrO’s proprietary technology uses a unique bi-phasic amine solvent. It was developed with a strong focus on effectiveness in chemical absorption/desorption of CO₂, superb loading characteristics, energy efficiency and stability (low degradation). This allows for applications on a wide range of potential emission sources from 5 to 50 % CO₂ for both new installation and to retrofit existing ones

The challenge

The generation of saturated steam sets a new benchmark in precise temperature control and efficient heat transfer. As a versatile process medium, saturated steam ensures a constant, even distribution of energy to match the strict reliability requirements that exist in industrial processes. Saturated steam is capable of retaining a constant temperature under controlled conditions. This feature makes its generation a forward-looking solution for thermal applications where the aim is to not only optimize performance but to improve efficiency and sustainability as well. Our customer CarbonOrO faced similar requirements when they tried to find a product that would convert the available superheated steam to the desired conditions. If the temperature is too high, malfunctions and failures can occur in the customer's downstream system. Plant performance is poor if the temperature is too low.

The solution

CarbonOrO opted to use our Type 7110 Water Bath Desuperheater because it fulfilled all their requirements.

Desuperheaters are used to cool superheated steam down to saturated steam temperature. Our Type 7110 allows for steam conditioning with an extremely precise temperature control for steam output over the entire load range.

Operators who run processes heated with saturated steam are often faced with the challenge that only superheated steam exists on site.

The Type 7110 Water Bath Desuperheater is the only solution to safely generate steam at saturated steam temperature.

Steam conditioning valves (e.g. Type 3281) or spray nozzles (e.g. Type 7115) can only cool down the steam to approx. 5 to 15 °C above the saturated steam temperature at the maximum.

The water bath desuperheater can additionally be fitted with a pressure control unit if the steam has a higher pressure or a controllable saturated steam pressure is required.

Processes heated with saturated steam often require small amounts of steam at varying output between 0 and 100 %. In this case, the water bath desuperheater is ideally suited since it guarantees perfect desuperheating over the entire load range.

Special features:
  • Desuperheating of superheated steam to saturated steam temperature
  • Extremely precise temperature control (<0.1 K in steady-state operation)
  • Steam mass flow control range from 0 to 100 %
  • No outlet section required
  • No steam breakthrough even at high load changes

Thanks to the successful cooperation and implementation of the system, the customer has already requested a standard custom system for future projects.

Products used

The tailor-made solution for the customer comprised a Type 7110 Water Bath Desuperheater, a FOCUS-1 Smart Process Node to control condensate drainage and a Type 7140 Condensate Recovery System. Two control cabinets for the Type 7110 and Type 7140 were integrated into the skid. The skid is designed to generate saturated steam at 2.7 bar and 130 °C. This steam is used to heat the desorber employed by the Carbon Capture Technology by CarbonOrO and release the carbon dioxide bonded to amines.

About CarbonOrO

CarbonOrO delivers carbon capture solutions to industrial CO₂ emitters across industries including waste management, energy, oil and gas, the glass, chemicals, steel, cement and concrete industries. In these hard-to-abate sectors, capturing and storing (or using) CO₂ is indispensable to reduce emissions.

In 2013, having become aware of the potential of carbon capture, CarbonOrO was created. The technology was built upon research from Eindhoven University of Technology, chemical company AkzoNobel and Dutch technology institute TNO.
