一.KULICKE & SOFFA 01483-4203-000-08引言
在石化行業(yè)的煉油裝置中，過去很少有采用變風量、變流量控制方式的，多是由鼠籠式異步電機拖動，進行恒速運轉。當需要調節(jié)風量、流量時，實際采用的辦法是調節(jié)擋板或節(jié)流閥，這種控制雖然簡單，但從節(jié)省能源的觀點來看，是很不經濟的。采用變頻器對風機、水泵類負荷進行轉速控制，對節(jié)約能源、提高經濟效益具有重要意義。
上海石油化工股份有限公司2007年在金山石化新建的120萬噸/年延遲焦化裝置中對部分380V電壓等級的泵類、風機首次引入Danfoss變頻調速控制，以適應操作條件、工況變化。投產后，變頻器運行穩(wěn)定，既得到了良好的工藝控制手段又節(jié)約了電力，取得了很好的效益。
二．項目簡介
延遲焦化技術是一種渣油輕質化最主要的加工方法之一，具有投資少，操作費用低，轉化深度高等優(yōu)點。所謂延遲焦化是指石油的二次加工技術，以貧氫的重質油為原料，在高溫(約500℃)進行深度的熱裂化和縮合反應，從而得到氣體、柴油、汽油、蠟油和焦炭的技術。延遲是指將焦化油(原料油或循環(huán)油)經過加熱爐加熱迅速升溫至焦化反應溫度，在反應爐管內不生焦，KULICKE & SOFFA 01483-4203-000-08而進入焦炭塔再進行焦化反應。本次新建的120萬噸/年延遲焦化裝置分三個部分：主要設備是加熱爐和焦炭塔。
采用一爐兩塔的工藝路線。（1）分餾部分，主要設備是分餾塔。（2）焦化氣體回收和脫硫，主要設備是吸收解吸塔，穩(wěn)定塔，再吸收塔等。（3）水力除焦部分。（4）焦炭的脫水和儲運。（5）吹氣放空系統(tǒng)。（6）蒸汽發(fā)生部分。（7）焦炭焙燒部分。選定爐出口溫度為495～500℃，焦炭塔頂壓力為0.15～0.2 Mpa。
三．KULICKE & SOFFA 01483-4203-000-08裝置工藝要求及變頻節(jié)能空間
原質重油由柴油泵從柴油集油箱（219 oC）抽出后分二路，一路返回柴油集油箱下作為熱回流，另一路至柴油-原料換熱箱，換熱至156 oC后，分出一部分返回分餾塔。經分餾塔頂空冷器冷卻后再分出兩股，一股作為溫控流股返回分餾塔，另一股經貧吸收柴油冷卻器冷至40oC后由貧吸收柴油泵打入柴油吸收塔作為柴油吸收劑，余下部分柴油經柴油冷卻器冷卻至50oC作為柴油產品出裝置。
裝置中分餾塔頂空冷器及蠟油空冷器，總數5臺，每臺功率37KW，當氣溫突變時，空冷器經常發(fā)生偏流現(xiàn)象，只能依靠人工開（停）空冷器來調節(jié)溫度，一方面經常造成空冷過剩使用，浪費電力；另一方面使C-6202主分餾塔的溫度和壓力難以控制，從而影響了產品餾的出口合格率。
焦炭塔吹汽、冷焦過程產生的大量高溫蒸汽及夾帶的少量油氣進入放空塔下部，從頂部打入蠟油餾分，洗滌下油氣中的柴油及以上餾分。放空塔底重油由放空塔底泵抽出，送經水箱冷卻器冷卻后，一部分作為放空塔頂回流，控制塔頂氣相溫度150oC左右。另一部分在液面控制下送裝置外污油罐分水處理后可回揀。放空塔頂出來的大量蒸汽及油氣經放空塔頂空冷器、放空塔頂后冷器冷卻到40oC進入放空塔頂氣液分離罐，分出的輕污油由污油泵送出裝置，污水由污水泵送至冷切焦水系統(tǒng)隔油處理后作為冷切焦水補充水。
KULICKE & SOFFA 01483-4203-000-08這一工藝流程中除高壓機泵外，另有一些配置380V電壓泵類的負荷，總數7臺，從37KW-160KW分多個功率段，在實際運行中存在變流量調節(jié)的要求，以前主要靠人工調節(jié)閥門開度，且大部分是放在閥門開度的70％-80％左右固定位置，甚至有些閥門的開度只有20％，系統(tǒng)運行在節(jié)流工作狀態(tài)，閥門上的能量損失全部被浪費。
變頻器在延遲焦化裝置上的應用，改變了以往使用節(jié)流方法調整泵類、風機的轉速，可取得較明顯的經濟效益。同時變頻器的應用減少甚至避免了因工頻運行大電流沖擊引起的調節(jié)閥及進出口管路的磨損現(xiàn)象，延長了設備的使用壽命。
在設備運行期間，讀取了變頻運行狀態(tài)下的一些數據，和電機額定數據比較可以明顯反映出設備有很大的節(jié)能空間。
2010年6月2日——全球領先的電力和自動化技術集團ABB近日宣布，將為山東南山鋁業(yè)股份有限公司建設的國內第一套“三機架鋁帶冷連軋機”提供全套量身定制的自動化解決方案，幫助南山鋁業(yè)在鋁加工特別是高品質制罐料市場進一步提高競爭力，保持其在國內鋁材行業(yè)市場的領導地位。
ABB過程自動化業(yè)務部北亞區(qū)和中國區(qū)負責人柏軻表示：“很高興看到ABB的領先自動化技術能夠參與并幫助中國鋁加工行業(yè)應用全球最先進的生產工藝。ABB是全球自動化技術領域的領導企業(yè)，在軋機領域擁有豐富的經驗和雄厚的技術，與南山鋁業(yè)的合作再次證明了我們的實力。”
山東南山集團輕合金有限公司總經理宋昌明說：“雙方在冷軋機項目上多年來有著成功的合作。ABB是負責任和可信賴的供應商，未來我們希望繼續(xù)與ABB公司密切合作并不斷擴大合作范圍?！?br />
南山鋁業(yè)此次采用全球最新工藝新建的三機架鋁帶冷連軋機將于2012年正式投入使用，生產線設計年產量35萬噸，居全國同行業(yè)前列。ABB為這套設備量身定制了全套自動化解決方案，包括自動化系統(tǒng)、計算機系統(tǒng)、數學模型、電機和傳動系統(tǒng)、儀表等。同時，ABB還將提供包括工程設計、安裝督導、現(xiàn)場調試在內的一系列支持服務。
ABB的自動化解決方案可以使冷連軋機實現(xiàn)高精度的厚度控制，將厚度公差控制在幾微米的范圍內，滿足了鋁罐材生產中對厚度精度的苛刻要求，保證了產品質量。其控制系統(tǒng)采用了ABB中壓傳動ACS6000和低壓傳動ACS800等先進設備，通過ABB領先的DTC（直接轉矩控制）技術，可以對電機轉距和速度進行快速和精確控制，有效提高軋機控制精度，減少計劃外停機，從而幫助客戶提高軋機的工作效率，減少維護成本。
ABB在金屬加工行業(yè)軋機控制技術方面居全球領先地位，特別是在鋁加工行業(yè)更是行業(yè)翹楚。ABB自上世紀80年代初以來已經參與中國多個大型鋁加工項目，如中鋁東北輕合金，中鋁西南鋁，中鋁瑞敏鋁業(yè)等等。 最近，ABB支持中鋁西南鋁建成了國內第一條雙機架冷連軋機，還參與了在建的中鋁瑞敏鋁冷軋項目，青海平安鋁業(yè)冷軋項目，云南鋁業(yè)冷軋項目，中煤能源大屯冷軋項目，河南萬基鋁業(yè)冷軋項目等等。
山東南山鋁業(yè)股份有限公司創(chuàng)建于1993年，KULICKE & SOFFA 01483-4203-000-08隸屬于大型民營企業(yè)南山集團。它擁有一條從能源、電力、氧化鋁、電解鋁到鋁型材、輕合金熔鑄、熱軋、冷軋、鋁箔的完整鋁加工產業(yè)鏈，是全球唯一短距離擁有最完整鋁產業(yè)鏈的鋁業(yè)公司。
