【摘要】：為了配合川西海相區(qū)塊含硫氣井的開發(fā),以彭州1井天然氣組分為基準(zhǔn),對(duì)天然氣脫硫工藝中的雙塔脫硫工藝、生物脫硫工藝和MDEA+自循環(huán)LO-CAT工藝從安全性、投資及運(yùn)行成本等方面進(jìn)行了詳細(xì)的研究對(duì)比。結(jié)果表明,雙塔脫硫工藝的安全性高、投資低、運(yùn)行成本低、裝置啟動(dòng)時(shí)間短、基本沒(méi)有廢液產(chǎn)生、成撬性好,富液集輸管道的安全性高,對(duì)區(qū)塊開發(fā)富液集輸工藝的適應(yīng)性好,最終選擇了雙塔脫硫工藝進(jìn)行天然氣脫硫及硫磺回收。同時(shí)對(duì)天然氣脫水和硫磺成型工藝進(jìn)行了優(yōu)選對(duì)比,結(jié)果表明,在脫水方面,由于本工程水露點(diǎn)的要求較低,且處理氣量較大,與固體吸附法和溶劑吸收法相比,三甘醇脫水工藝更適應(yīng)于本工程;在熔硫方面,間歇熔硫工藝在能耗、排污以及藥劑消耗量等方面較連續(xù)熔硫具有明顯優(yōu)勢(shì);在硫磺成型方面,水冷造粒工藝成熟可靠,優(yōu)勢(shì)較大。為了縮短工期、降低成本、提高質(zhì)量,并結(jié)合試采的需要,對(duì)整套裝置進(jìn)行了模塊化、撬裝化設(shè)計(jì),整套裝置共設(shè)計(jì)10個(gè)模塊、45個(gè)撬塊,同時(shí)對(duì)模塊化建造及運(yùn)輸回裝提出了要求。最后對(duì)脫硫裝置配套的天然氣集輸系統(tǒng)進(jìn)行了設(shè)計(jì),確定了采用加熱工藝防止節(jié)流降壓時(shí)生成水合物;采用重力分離器進(jìn)行氣液分離;經(jīng)脫硫裝置處理后的凈化氣外輸至彭都管線的慶興閥室。
[Abstract]:In order to cooperate with the development of sulfur-bearing gas wells in the marine area of western Sichuan, taking the natural gas components of well Pengzhou 1 as the benchmark, the double tower desulphurization process, the biological desulfurization process and the MDEA self-circulating LO-CAT process in the natural gas desulfurization process are considered to be safe. The results show that the double tower desulphurization process has high safety, low investment, low operation cost, short start-up time, no waste liquid, and good prying property. Because of its high safety and adaptability to the development of liquid-rich gathering and transportation technology in the block, the double tower desulfurization process is selected for natural gas desulfurization and sulfur recovery. At the same time, the natural gas dehydration and sulfur forming processes are optimized and compared. The results show that the dewatering process of triethylene glycol is more suitable for this project than solid adsorption method and solvent absorption method because of the low dew-point requirement and large amount of gas treatment in the water of the project, and in the aspect of sulfur melting, the dewatering process of triethylene glycol is more suitable for this project than solid adsorption method and solvent absorption method. The intermittent sulfur melting process has obvious advantages over continuous sulfur melting in the aspects of energy consumption, sewage discharge and pesticide consumption, while in sulfur forming, the water-cooled granulation process is mature and reliable, and has a great advantage, in order to shorten the time limit, reduce the cost, improve the quality, etc. Combined with the needs of the test and mining, the whole set of equipment was modularized, prying design, the whole device designed a total of 10 modules, 45 pry blocks, At the same time, the requirements of modularization construction and transportation reload are put forward. Finally, the natural gas gathering and transportation system of desulphurization unit is designed, and the heating process is adopted to prevent the formation of hydrates during throttling and lowering pressure. Gravity separator was used to separate gas and liquid and purified gas was transported to Qingxing valve chamber of Pengdu pipeline after desulfurization.
