Phymetrix 便攜式水分分析儀型號(hào) PPMa 顯示在天然氣低溫分餾器中的使用。 PPMa 連接在甲醇注入后的摩爾篩干燥器之后，就在分餾低溫分離器之前。 PPMa 設(shè)置為在夜間記錄氣體的水分含量，以評(píng)估摩爾篩干燥器的容量和柱切換時(shí)間。保持低水分含量有很多好處，包括減少解凍低溫分離器以去除積冰的需要。
PPMa 在寬溫度范圍內(nèi)運(yùn)行的能力及其抗沖擊 IP 65 防風(fēng)雨外殼使其即使在的環(huán)境中也能使用，例如科羅拉多州冬季暴風(fēng)雪夜間伐木。傳感技術(shù)對(duì)甲醇的不敏感性也是該測量中獨(dú)特且重要的因素。
數(shù)據(jù)表明，摩爾篩干燥器尺寸過小，柱子切換不夠頻繁。循環(huán)中大約 6 或 7 小時(shí)出現(xiàn)的水分突破會(huì)增加不希望的水分。它向工程師表明，他們需要更頻繁地更換色譜柱并通過提高再生循環(huán)溫度和/或流量來更好地再生摩爾篩。
沒有其他便攜式分析儀可以在這種惡劣的環(huán)境中使用。然而，PPMa 不僅可以運(yùn)行，而且可以進(jìn)行其他分析儀無法執(zhí)行的準(zhǔn)確和快速的測量。大多數(shù)其他分析儀都會(huì)受到甲醇注入氣流的干擾。
