該項(xiàng)目采用先進(jìn)的粉體流冷卻新技術(shù)，替代傳統(tǒng)的流化床風(fēng)冷技術(shù)，降低了運(yùn)行電耗；采用重堿爐氣熱量回收技術(shù)，將重堿爐氣熱源用于提高母液溫度，降低了蒸餾蒸汽消耗，每小時(shí)節(jié)省冷卻循環(huán)水85立方米，具有雙重節(jié)能降耗效果。
?；儔A廠老線年生產(chǎn)能力120萬(wàn)噸，主要生產(chǎn)輕堿，重堿只占40%左右，而目前重堿市場(chǎng)需求和價(jià)格明顯好于輕堿。為適應(yīng)市場(chǎng)需求，優(yōu)化產(chǎn)品結(jié)構(gòu)，盡快提高重堿生產(chǎn)能力，將作為備機(jī)使用的5#輕堿爐進(jìn)行改造，改產(chǎn)固相水合重堿，年增加20萬(wàn)噸重堿生產(chǎn)能力，重堿生產(chǎn)比例提升到60%左右。按目前重堿比輕堿每噸增加50元計(jì)算，年增效益1000萬(wàn)元。
