b2
产品描述

装置特点:从焦炉煤气、煤气、甲醇尾气、合成氨尾气、变换气、其它驰放气以及甲醇裂解、氨分解、天然气裂解、催化裂化干气等含氢气气源出,多种技术相结合,制取高纯氢气。

适用范围:因地制宜将TSA、PSA、VPSA气体纯化技术结合在一起,为用户提供完善经济的工艺解快方案,产品纯度高,回收率高。

吸附塔:采用气体分布效果更好,床层死空间更小的新颖结构。床层内气流均匀,其顶端有可靠的压紧装置,防止吸附剂串动、粉化,具有较高的气体回收率。
吸附剂:成都天蓝与合作科研机构研制的变压吸附专用吸附剂、催化剂、产气纯度高,提高了装置的可靠性。

 

 

Application Scope:Extract high purity H2 from hydrogen-containing gas, such as coke-oven gas, coal gas, methanol tail gas, tail gas from ammonia synthesis, shift gas, another periodic off- gases and methanol cracking, ammonia decompounding, natural gas cracking, iol dry gas from catalytic cracking with many kinds of techniques.

Process Flows:Combine TSA, PSA and VPSA gas purification technique adapting to the local circumstances to provide users with most complete and economical technical solutions and high purity product and high recovery ratio.

Adsorption Tower:Use the latest structure with better gas distribution effect and less dead space of bed. The air flow is uniform inside with a reliable clamping device at the top of bed to prevent moving adsorbent vibration and pulverizat-ion. the structure are employed to get highet gas recovery tatio.

Adsorbent:Use exclusive PSA adsorbents and catalysts developed by Tianlan company and research institutions to produce high purity gas and increase the reliability of the equipments.
