Engineered with high static water adsorption capacity, optimized pore tortuosity, and elite hydrothermal resistance for process plants in the Barcelona Metropolitan Area.
As the primary industrial driver of Southern Europe, the Greater Barcelona metropolitan area—spanning the Zona Franca logistics enclave, the Baix Llobregat chemical clusters, and the integrated petrochemical belt linking to Tarragona—requires world-class synthetic zeolite materials engineered for strict thermodynamic conditions.
The Enagás regasification plant at the Port of Barcelona operates as one of Europe’s critical LNG gateways. Pre-cooling dehydration and deep mercaptan removal demand high-performance Type 13X and 4A molecular sieves capable of keeping moisture below 0.1 ppmv to prevent catastrophic cryogenic hydrate formation down to -162°C.
Home to Spain’s pharmaceutical pioneers (Almirall, Grifols, Ferrer, Esteve), these facilities demand absolute sterility and traceable solvent drying. Our 3A zeolites selectively remove water from volatile solvents (ethanol, acetone, acetonitrile) without co-adsorbing the valuable solvent matrix or generating dusting impurities.
Aligned with the "Pla de l’Energia i Canvi Climàtic de Catalunya," projects across Zona Franca and Martorell are accelerating biomethane grid injections and electrolyzer-driven H2 generation. Custom molecular sieves offer the exact selectivity required for H2 purification via Pressure Swing Adsorption (PSA) systems.
Designed to exceed ASTM and DIN standards, Zhongtai synthetic zeolites feature high active aluminosilicate framework density, delivering sustained mass-transfer performance through thousands of thermal cycles.

Operating from Pingxiang, Jiangxi Province—the undisputed capital of industrial mass-transfer media—Zhongtai fuses high-grade raw mineral access with fully automated PLC-controlled synthesis and rotary firing kilns.
Closed-loop DCS monitoring guarantees exact Si/Al stoichiometric ratios in every batch. This consistency eliminates crystalline structural defects and gives beads high attrition resistance, preventing bed channelling and downstream pressure drop spikes.
With an annual output exceeding 15,000 metric tons of synthetic zeolites, our manufacturing schedule protects buyers from spot shortages and market volatility. We deliver consistently to EPC plant revamps and emergency bed changeouts across Spain.
Every shipment bound for maritime transit through the Mediterranean undergoes rigorous packaging: steel drums with internal polyethylene foil bags or vacuum-sealed super sacks to maintain moisture levels below 1.0 wt% upon dockside arrival in Barcelona.
Receive comprehensive engineering datasheets, batch analysis certificates (CoA), and competitive port-delivered quotations within 24 hours.
Procuring raw engineering adsorbents into Spain demands complete compliance with European Union frameworks and predictable sea freight transit times.
All synthetic aluminosilicate grades strictly comply with Regulation (EC) No 1907/2006 (REACH). Full registration dossiers, certified Safety Data Sheets (SDS) in Spanish and English, and RoHS documentation are supplied with each export.
We work closely with certified Spanish freight forwarding agents to ensure prompt customs release under TARIC codes 2842.10 and 3824.99, preventing port demurrage and accelerating delivery to site warehouses.
Proper bed loading decides service life. We supply detailed dense-phase loading guidelines, socks-loading recommendations, and pre-commissioning thermal regeneration curves (200°C–350°C) tailored to your unit design.
Beyond standard zeolites, our Pingxiang production base supplies advanced filtration media, permanganate-impregnated chemisorbents, and precision tower packings to process plants worldwide.
Clear technical and commercial answers addressing drying operations, regeneration parameters, and international freight handling for Spanish industrial clients.
Zeolite 3A features an effective pore diameter of roughly 3 Ångströms (0.3 nm), created via potassium ion exchange on the Type A aluminosilicate lattice. This pore opening admits water molecules (~2.6 Å) while completely excluding hydrocarbons such as ethylene, propylene, and alcohols like ethanol (~3.9–4.4 Å). This selectivity prevents internal co-adsorption and polymerization (coking) inside the micropores, protecting overall cycle capacity and avoiding thermal runaway during desorption.
Our 13X APG (Air Pre-Purification Grade) is engineered to deliver high dynamic adsorption capacity for both carbon dioxide (CO₂) and moisture (H₂O). In cryogenic air separation and LNG liquefaction trains, trace impurities will crystallize and block heat exchangers at sub-zero temperatures. 13X APG maintains dynamic breakthrough points that keep water below 0.1 ppmv and CO₂ below 0.5 ppmv under sustained high superficial linear velocities.
Standard export orders leave directly from the major maritime hubs of Shanghai or Ningbo via weekly direct liner services to the Port of Barcelona, with ocean transit running 26 to 32 days. For scheduled turnaround maintenance or emergency plant replacements, air freight dispatch from Changsha (CSX) or Shanghai (PVG) to Josep Tarradellas Barcelona-El Prat Airport (BCN) takes 3 to 5 working days.
Yes. Our Pingxiang laboratory formulates molecular sieve beads using custom attapulgite or kaolin binder systems, or direct binderless crystallite matrix synthesis. This increases mechanical crush strength up to 100 N/bead for deep desiccant beds subjected to aggressive hydraulic heads and high cyclic gas pulsations.
Thermal swing adsorption (TSA) regeneration requires heating the bed with a dry, inert purge gas (such as dry nitrogen or off-gas) to 200°C–315°C (390°F–600°F), depending on the adsorbed species. The purge flow must follow a controlled ramp rate (~1.5°C to 2°C/min) to prevent thermal shock and hydro-pasteurization of the crystal framework. Once the regeneration temperature plateau clears and effluent moisture subsides, the bed is cooled with dry purge gas before returning to the adsorption cycle.
