In industrial processes, it is vital to continue to innovate in order to remain competitive, optimize current plant processes, reduce costs as much as possible and comply with increasingly restrictive laws to minimize environmental impact. One of these innovations is the hygroscopic cycle (HCT), an emerging technology that offers multiple benefits.
This technology not only promises operational efficiency, but also a significant reduction in the use of natural resources and an improvement in environmental sustainability.
How does the Hygroscopic Cycle work?
The hygroscopic cycle is an innovation based on the Rankine cycle, widely used for steam power generation. This cycle uses physical and chemical principles to improve steam condensation efficiency.
Unlike traditional systems that use large amounts of water for cooling, HCT is a “dry” technology, as it uses ambient air to dissipate thermal energy and condense steam. This process reduces water consumption to practically zero and increases the efficiency of the process allowing to obtain the same electrical production with a smaller amount of steam thus reducing fuel consumption and with it the emissions of greenhouse gases such as CO₂, as well as other pollutants such as NOx and SOx.
Industry applications
Industrial processes benefit greatly from the implementation of the hygroscopic cycle. Some of its applications are detailed below:
Reduction of water consumption
Many power plants require large quantities of water for turbine exhaust steam cooling. The adoption of the hygroscopic cycle can lead to a drastic reduction in water consumption in industry, which is especially beneficial in water-scarce regions.
Improving energy efficiency
By improving heat transfer efficiency, the condensing pressure of the turbine can be lowered, producing a greater amount of electricity with the same amount of steam, thus improving the plant’s energy efficiency. On the other hand, operating costs are much lower than technologies that use cooling towers, since they do not require cleaning and biocide treatments to prevent the appearance of legionella.
Minimization of pollutant emissions
This technology helps reduce harmful gas emissions, contributing to a lower environmental impact. This is crucial to comply with increasingly stringent environmental regulations and improve the sustainability of industrial operations.
Operational flexibility
HCT allows greater freedom of location for industrial plants, as they are not dependent on abundant water sources. This opens up the possibility of installing plants in areas with water restrictions or where low environmental impact is required.
HCT applications in industrial processes
The hygroscopic cycle has applications in various industry sectors, offering unique benefits in each. Examples of these applications are:
- High efficiency cogeneration.
- Elimination of tufts.
- Steam condensation processes.
- Energy recovery from stack tail gases.
Additional advantages of the Hygroscopic Cycle in industry
In addition to the applications mentioned above, the hygroscopic cycle offers general advantages that make it attractive for a wide range of industries:
- Reduced Environmental Impact: by avoiding large water vapor plumes, also known as plumes, and massive cooling structures, the technology minimizes visual impact and improves integration with the natural environment.
- Ecosystem protection: dry technology avoids liquid effluents, thus protecting local flora and fauna and eliminating the emission of harmful microorganisms.
- Reduced Operating Costs: reduced water requirements and improved energy efficiency translate into lower operating and maintenance costs.
