Non-Clogging Supercritical Fluid Back Pressure Regulators 不堵塞的超临界流体背压调节器
Equilibar is pleased to introduce the blockage resistant BR Series back pressure regulators. This series is ideal for specialty applications, particularly supercritical CO2 extraction applications, but is also useful for any process in which clogging, blocking, or freezing could be an issue. equilibar 很高兴推出抗堵塞 br 系列背压调节器。该系列是特殊应用的理想选择, 尤其是超临界 co2 萃取应用, 但对于可能存在堵塞、堵塞或冻结的任何工艺也非常有用
This series integrates proprietary design features to help customers achieve precision control by reducing the Joule-Thomson effect of supercritical process fluids passing through the unit. A primary design feature in this regulator series is a downstream expansion cavity that provides a continuously increasing cross-sectional area to eliminate convergence points for ice buildup. Additionally, this large thermal mass provides increased heat transfer area to heat the outlet fluid through several different means. Lastly, this series has specially designed O-ring grooves to reduce stress during rapid decompression, increasing O-ring lifetimes. This series has several custom fitting options, including an outlet flange, tube stub, or NPT fittings. 该系列集成了专有的设计功能, 通过降低超临界工艺流体通过该装置的焦耳-汤姆森效应, 帮助客户实现精确控制。该调节器系列的一个主要设计特点是下游膨胀腔, 它提供了不断增加的横截面面积, 以消除冰层堆积的收敛点。此外, 这种较大的热质量提供了更多的传热面积, 通过几种不同的方式加热出口流体。最后, 该系列具有专门设计的 o 形圈凹槽, 可在快速减压过程中减少应力, 从而延长 o 形圈的使用寿命。该系列有多种定制配件选项, 包括出口法兰、管柱或 npt 配件。
专为适应超临界萃取环境而设计
br 系列 (正在申请专利) 是专门为解决在减压过程中超临界气体膨胀时出现快速冷却时遇到的需求而设计的。
内部通道的形状可防止冰或粘性油的堆积, 因此 br 可在目标设定值处自由调节。
车身采用优质不锈钢 cnc 加工而成。
隔膜材料包括聚酰亚胺、聚四氟乙烯和 peek, 具体取决于所使用的共溶剂和达到的最高温度。
o 形环腔的设计是为了限制当 sco2 渗透 o 形圈材料时发生的爆炸减压。
o 形圈材料选项包括 buna-n、viton、ptfe 和 dupont kalrez, 具体取决于应用。
