【摘要】：隨著天然氣需求量的不斷增長,天然氣凈化技術(shù)的開發(fā)和研究越發(fā)重要。天然氣脫碳是預(yù)處理工藝的關(guān)鍵環(huán)節(jié),目前胺法脫碳技術(shù)在天然氣脫碳領(lǐng)域得到了廣泛應(yīng)用,其中混合胺法因吸收能力強(qiáng)、反應(yīng)速度快、適用范圍廣、再生能耗低、氣體損失小、凈化程度高、溶液腐蝕小等優(yōu)點(diǎn)而被廣泛關(guān)注。而吸收劑本身的性能直接影響天然氣的凈化效果,胺液吸收劑種類繁多且各有特點(diǎn),因此篩選出一種高效節(jié)能且深度脫碳的胺液配方十分重要。目前國內(nèi)外普遍采用以MDEA(甲基二乙醇胺)為主體的復(fù)配胺液為吸收劑,為適應(yīng)尋找經(jīng)濟(jì)、高效的新型吸收劑的需求,本文選取同為叔胺的TEA(三乙醇胺)為主體進(jìn)行混合胺液的優(yōu)選研究。本論文首先針對TEA單一胺液展開小型試驗(yàn)研究,通過吸收和解吸試驗(yàn)的結(jié)果分析TEA的吸收和解吸性能,并確定了配方優(yōu)選試驗(yàn)的操作參數(shù);在單一胺液的研究基礎(chǔ)上,對TEA為主體的混合胺液展開配方優(yōu)選研究,分別在TEA主體胺液中添加A、B、C、D、E五種添加劑,考察不同添加劑對混合胺液吸收解吸性能的影響,篩選出A、C及E為較優(yōu)的添加劑;然后分別研究了三種不同濃度配比的TEA+A、TEA+C以及TEA+E混合胺液的吸收與解吸性能,篩選確定最優(yōu)的混合胺液配比分別為2mol/LTEA+1mol/LA、2mol/LTEA+1mol/LC、2.4mol/LTEA+0.6mol/LC和2mol/LTEA+1mol/LE;針對四種較優(yōu)的混合胺液,在循環(huán)條件下展開吸收和解吸試驗(yàn),綜合對比評價(jià)每種胺液的吸收、解吸及循環(huán)性能,篩選出最優(yōu)的混合胺液配方為2mol/LTEA+1mol/LA;最后利用中試裝置和HYSYS軟件對最優(yōu)配方進(jìn)行試驗(yàn)和模擬的雙重驗(yàn)證,驗(yàn)證結(jié)果表明,最優(yōu)配方脫碳效果良好,滿足實(shí)際天然工業(yè)中的凈化要求。
[Abstract]:With the increasing demand for natural gas, the development and research of natural gas purification technology is becoming more and more important. The decarbonization of natural gas is the key link of the pretreatment process. At present, the amine-decarburization technology has been widely used in the field of natural gas decarbonization, among which the mixed amine method has strong absorption capacity, fast reaction speed, wide application range and low regeneration energy consumption. The advantages of small gas loss, high degree of purification and small corrosion of solution have attracted wide attention. The performance of absorbent has a direct impact on the purification effect of natural gas. There are many kinds of amine-liquid absorbent and each has its own characteristics. Therefore, it is very important to select a formula of amine-liquid with high efficiency and energy saving and deep decarbonization. At present, MDEA (methyl diethanolamine) is widely used as absorbent in order to meet the demand of economic and efficient new absorbent. In this paper, tea (triethanolamine), which is the same as tertiary amine, is selected as the main body to study the optimization of mixed amine solution. In this paper, a small scale experimental study was carried out on the TEA single amine solution. The absorption and desorption properties of TEA were analyzed by the results of the absorption and desorption tests, and the operating parameters of the formula optimal selection test were determined, on the basis of the study of the single amine solution, the absorption and desorption properties of TEA were analyzed. The formulation of the mixed amine solution with TEA as the main body was studied. Five kinds of additives were added to the main amine solution of TEA. The effects of different additives on the absorption and desorption of the mixed amine solution were investigated, and the better additives were screened out. Then, the absorption and desorption properties of three different concentrations of TEA tea C and TEA E mixed amines were studied, and the optimum mixture ratio was determined to be 2mol/LTEA 1 mol / L L 偽 2 mol / L T EA 2. 4 mol / L LTEA 0.6mol/LC and 2mol/LTEA 1 mol / L LE. for four kinds of mixed amines, The absorption and desorption tests were carried out under cyclic conditions, and the absorption, desorption and cycling properties of each amine solution were compared and evaluated. The optimal mixture of amines was selected as 2mol/LTEA 1mol / L a. Finally, the optimal formula was tested and simulated by pilot plant and HYSYS software. The results showed that the decarbonization effect of the optimal formulation was good. To meet the purification requirements in the actual natural industry.
