2014年12月中下旬，當(dāng)成品油價格“九連跌”時，天然氣與液化氣的價差高達400元/噸。經(jīng)換算，廣西石化生產(chǎn)耗費天然氣25噸/小時，依此測算，如改為燒價格較低的液化氣，每天可節(jié)省燃料成本高達20多萬元，于是公司決定將所有加熱爐改為燒液化氣。
據(jù)廣西石化生產(chǎn)技術(shù)處負責(zé)人介紹，各煉油裝置的燃料系統(tǒng)專門設(shè)計有天然氣與液化氣相互切換的生產(chǎn)運行流程。在氣溫偏低時，液化氣罐壓力較低，為減少冷凝水的產(chǎn)生，儲運部門給燃料氣管網(wǎng)投用伴熱線，進行伴熱加溫，并及時排凝，保證管網(wǎng)壓力穩(wěn)定。
