Linuo LNQC: Pure Hydrogen for Off-Grid Wind Power
This is a new type customized by our company for the first phase of a 10 MW off-grid wind-to-hydrogen project. PTSA Hydrogen Deoxygenation and Dehydration Purification Unit LNQC-400Ex , the project adopts Fully Off-Grid Operation Mode , it has broken free from reliance on the conventional power grid, offering a brand-new pathway for the on-site conversion of wind and solar resources in remote areas.
The equipment employs a specialized PSA+TSA purification process, with the adsorption and drying stages implemented using a dual-tower configuration. Variable temperature and variable pressure The regeneration process utilizes less than 5% of the dried product gas as the regenerating gas, employing heated regeneration and high‑altitude venting. During the pressure‑relief phase, shallowly adsorbed moisture is rapidly removed, while the temperature‑swing step simultaneously achieves deep desorption. This dual‑mode regeneration approach is more thorough and efficient than the conventional three‑tower temperature‑swing process, better enabling long‑term, stable attainment of low dew‑point specifications.
The equipment features a compact layout, high stability, and flexible operation, enabling it to handle the highly variable and complex operating conditions of off-grid wind‑to‑hydrogen systems. Coupled with a downstream buffer system, it supports irregular, intermittent utilization, thereby completely overcoming the issue of adsorption–regeneration equilibrium disruption inherent in conventional processes.
• The unit is equipped with a specially designed, imported alkali‑solution coalescing filter that captures and separates trace droplets of potassium hydroxide solution from the feed gas, thereby protecting the downstream deoxygenation catalyst.
• An external heater is employed, with a heat flux on the heat‑exchange tube surface of less than 2 W/cm². Compared with conventional internal heaters, it provides more uniform airflow distribution, superior desorption performance, and extended service life. Moreover, by using fast on/off control via thyristors to regulate power, precise temperature control is achieved, preventing overheating and ensuring the system’s long‑term safe and stable operation.
• Custom‑designed metal catalysts for substrates offer advantages such as high space velocity, high activity, excellent stability, and a low light‑off temperature, thereby reducing both initial capital investment and ongoing operating costs. Oxygen levels can be as low as 0.5 ppm. Based on the oxygen content in the process stream, heat recovery exchangers can be engineered to harness the heat generated by the catalytic reaction, further cutting heating energy consumption and circulating water usage.
• Equipped with a Siemens PLC control cabinet and a touch screen, it supports DCS communication at the user end, features fully automated safety interlock control, and incorporates a redundant design to enhance system safety. Its intelligent human–machine interface ensures easy operation, with smart one‑button start-up and on/off control. Additional functions include real-time monitoring of analyzer flow rates, automatic shutdown upon stoppage to protect sensors, and other safeguards, significantly improving system safety and reliability while enabling highly intelligent, unattended operation.
