Inside Haina’s Approach to Carbon Molecular Sieves

Byadmin

Selecting a carbon molecular sieve starts with a question about the generator. What purity and output must the system deliver, and under which conditions? Haina connects this application discussion with material development and manufacturing at its facility in Mingguang, Anhui.

From material development to production

Anhui Haina New Materials Co., Ltd. develops and manufactures carbon molecular sieves and porous carbon materials. Its carbon molecular sieve range serves PSA nitrogen generation. The company brings research, development and production together at its Mingguang facility and reports an annual production capacity of 12,000 tonnes.

Haina develops key production equipment in-house as part of its work to improve material purity and manufacturing efficiency. For customers comparing materials, the grade designation is a starting point. The performance data and the operating conditions behind those figures help determine which grades warrant a closer look.

What product data can tell you

Start with the required nitrogen purity, then compare productivity and any available air consumption data at that same purity. Keep the stated test pressure, cycle conditions and units alongside the results. This makes it easier to compare grades and discuss how the data relate to the intended equipment.

For an existing generator, consider the current bed volume, feed-air quality and cycle settings. For a new generator, compare the data against the design duty and expected range of operating conditions. Those details help determine what to check during commissioning or qualification.

Start with the duty, then agree on what to verify

  • Define the product gas specification, normal demand and peak flow.
  • Share the inlet air conditions and the generator’s design or operating limits.
  • Identify the current adsorbent if the project involves an existing bed.
  • Ask which data, sample size and acceptance criteria are appropriate for the next step.

For a replacement project, record the existing unit’s pressure, cycle timing, output and residual oxygen before changing the bed. This gives you a baseline for evaluating performance after the change. If the project is still in design, agree on test conditions that reflect the planned generator and its operating duty.
