【摘要】：隨著蘇丹油氣產(chǎn)量特別是蘇丹六區(qū)高酸高鈣原油產(chǎn)量的不斷增加,加工高酸高鈣六區(qū)原油是蘇丹煉廠今后面臨的重要課題。本論文首先對(duì)六區(qū)稠油的性質(zhì)進(jìn)行了全餾分分析,根據(jù)六區(qū)稠油的特點(diǎn)進(jìn)行脫鈣技術(shù)研究和稠油加工工藝研究,最后對(duì)稠油加工技術(shù)工業(yè)化運(yùn)行情況進(jìn)行了分析。論文首先對(duì)蘇丹六區(qū)稠油的基本性質(zhì)及全餾分性質(zhì)做了全面分析,得到了蘇丹六區(qū)原油的基本屬性。結(jié)果表明:蘇丹稠油屬低硫環(huán)烷-中間基原油,其密度大,輕質(zhì)油收率低,硫含量低,氮含量、水含量和鹽含量較高,酸值高達(dá)l3.82mgKOH/g;所含金屬中鈣、鈉、鎂、鎳含量高,分別為1652.0μg·g-1、264.0μg·g-1、8.5μg·g-1和18.3μg·g-1,尤其是高含鈣量給加工帶來(lái)很大的困難。針對(duì)蘇丹六區(qū)原油鈣含量高造成的加工問(wèn)題進(jìn)行了脫鈣技術(shù)研究。結(jié)果表明:脫鈣劑A和脫鈣劑B兩種脫鈣劑均有較高的脫鈣率,使原油脫后鈣含量低于100μg·g-1,脫后油中的鹽含量3μg·g-1,達(dá)到了延遲焦化裝置對(duì)原油鈣鐵含量的技術(shù)要求。但與脫鈣劑A相比,脫鈣劑B具有更高的脫鈣率和脫鐵率。隨著劑鈣質(zhì)量比含量的增加,蘇丹六區(qū)稠油中的鈣含量逐漸下降,當(dāng)劑鈣比由0變?yōu)?:1時(shí),鈣含量大幅度下降;且劑鈣比含量越高,脫鈣率越大。加入脫鈣劑后焦化柴油鐵含量有所增加,隨著劑鈣比的增加,鐵含量呈現(xiàn)先增加后降低的趨勢(shì);而酸值呈現(xiàn)先降低后增加的趨勢(shì)。加入脫鈣劑后焦化蠟油鐵含量有所降低,隨著劑鈣比的增加,鐵含量呈現(xiàn)先降低后增加的趨勢(shì);酸值呈現(xiàn)逐漸增加的趨勢(shì)。根據(jù)蘇丹成品油市場(chǎng)需求及原料性質(zhì),對(duì)高酸原油的脫酸工藝進(jìn)行了研究。結(jié)果表明:采用原油延遲焦化的熱脫酸工藝,可以有效的降低焦化餾分油的酸值,脫酸率在95%以上,汽油柴油二者的收率可達(dá)60%以上,特別是柴油收率可達(dá)40%以上,很適合蘇丹對(duì)柴油的需求。由六區(qū)稠油加工技術(shù)工業(yè)化運(yùn)行情況分析得到,延遲焦化裝置加工含酸原油若選擇合適的材料,可以有效的控制裝置的腐蝕問(wèn)題,實(shí)現(xiàn)裝置的長(zhǎng)周期生產(chǎn),采用加氫精制和連續(xù)重整技術(shù),加工延遲焦化汽柴油,可以滿(mǎn)足對(duì)產(chǎn)品質(zhì)量的需求,并且能夠?yàn)闊拸S提供富余的氫氣。
[Abstract]:With the increasing production of oil and gas in Sudan, especially the production of high-acid and high-calcium crude oil in the six regions of Sudan, the processing of crude oil in high-acid and high-calcium region is an important subject that Sudanese refineries will face in the future. In this paper, the properties of heavy oil in area six are analyzed, and the decalcification technology and processing technology of heavy oil are studied according to the characteristics of heavy oil in area six. Finally, the industrial operation of heavy oil processing technology is analyzed. In this paper, the basic properties and the whole fractions of heavy oil in the six regions of Sudan are analyzed, and the basic properties of crude oil in the six regions of Sudan are obtained. The results show that Sudan heavy oil belongs to low sulfur naphthene intermediate base crude oil, its density is high, light oil yield is low, sulfur content is low, nitrogen content, water content and salt content are higher, acid value is as high as l3.82 mg KOH / g; The contents of calcium, sodium, magnesium and nickel are 1652.0 渭 g ~ 1264.0 渭 g ~ (-1) 渭 g g ~ (-1) and 18.3 渭 g g ~ (-1) respectively. The decalcification technology was studied for processing problems caused by high calcium content in crude oil in six regions of Sudan. The results showed that both decalcifying agent A and decalcifying agent B had high decalcification rate, and the calcium content of crude oil was less than 100 渭 g -1, and the salt content of oil after decalcification was 3 渭 g -1. The technical requirements of the delayed coking unit for the content of calcium and iron in crude oil have been achieved. Compared with decalcifying agent A, decalcifying agent B has higher decalcification rate and iron removal rate. With the increase of the ratio of agent to calcium, the content of calcium in heavy oil in the six regions of Sudan gradually decreased, and when the ratio of agent to calcium changed from 0 to 2:1, the content of calcium decreased significantly, and the higher the ratio of agent to calcium was, the greater the decalcification rate was. After adding decalcifying agent, the iron content of coking diesel increased. With the increase of calcium ratio, the iron content increased first and then decreased, while the acid value decreased first and then increased. The iron content of coking wax oil decreased after adding decalcifying agent. With the increase of calcium ratio, the iron content decreased first and then increased, and the acid value increased gradually. The deacidification process of high acid crude oil was studied according to the market demand and raw material properties of Sudan refined oil. The results show that the acid value of the coking distillate oil can be effectively reduced by using the thermal deacidification process of delayed coking of crude oil. The acid removal rate is more than 95%, the yield of gasoline and diesel oil is over 60%, especially the yield of diesel oil can reach more than 40%. It is suitable for the demand of diesel oil in Sudan. From the analysis of the industrial operation of heavy oil processing technology in six regions, it is concluded that if suitable materials are selected for processing sour crude oil in delayed coking plant, the corrosion problem of the device can be effectively controlled, and the long period production of the device can be realized. Using hydrofining and continuous reforming technology to process delayed coking gasoline and diesel oil can meet the demand of product quality and provide excess hydrogen for refinery.
