【摘要】：針對渤海特稠油的原油黏度大、油品密度高,油水分離十分困難的特點(diǎn),研制了絕緣電極并開展了室內(nèi)自然沉降和靜電聚結(jié)脫水實(shí)驗(yàn)。實(shí)驗(yàn)結(jié)果表明,所研制的絕緣電極可以適應(yīng)高含水特稠油脫水工況,對于初始含水70%~90%的乳化液,處理溫度110℃,在適當(dāng)?shù)碾妶鰪?qiáng)度和藥劑濃度作用下,沉降時(shí)間40 min,脫后含水可以低于30%;對于初始含水30%~60%的乳化液,處理溫度130℃,在適當(dāng)?shù)碾妶鰪?qiáng)度和藥劑濃度作用下,沉降時(shí)間40 min,脫后含水可以低于30%,滿足相關(guān)規(guī)范中對進(jìn)入常規(guī)電脫水器進(jìn)一步處理的要求。通過與自然沉降脫水實(shí)驗(yàn)進(jìn)行對比,靜電聚結(jié)脫水技術(shù)能夠較大幅度地提高特稠油脫水效率,大幅降低海上特稠油脫水設(shè)備的尺寸和質(zhì)量。本文實(shí)驗(yàn)結(jié)果對海上特稠油靜電聚結(jié)脫水處理工藝設(shè)計(jì)具有一定指導(dǎo)意義。
[Abstract]:In view of the high viscosity, high density and difficult separation of oil and water in Bohai Sea super heavy oil, an insulated electrode was developed and the experiments of natural sedimentation and electrostatic agglomeration dehydration in laboratory were carried out. The experimental results show that the insulation electrode can adapt to the dehydration condition of high water cut super heavy oil. For the emulsion with initial water cut 70% 鈮，
