PROCESS DESCRIPTION 工艺描述
The plant is designed to continuously process freshly degummed soybean oil and rapeseed oil as per the
attached flow diagram.
该工段用于连续加工新鲜的脱胶豆油以及菜籽油。 具体工艺参见附后的工艺流程图 。 ACID CONDITIONING AND NEUTRALIZATION ACCORDING TO THE LONG MIX METHOD
长混工艺的酸调节中和
The feedstock enters the plant at a controlled rate and is heated to about 70 oC by neutralized
oil in Feed
Economizer E000 or by steam in the Feed Heater E001 during the start-up. Phosphoric acid is injected at a
controlled rate and intensively contacted with the oil in the Acid Mixer M080, later on, the mixture is retained in
the acid reaction tank M084 for some time to ensure completely to transfer NHP into HP. These materials are
later removed together with the soapstock formed during neutralization.
原料油通过中和油节能器E000或在开车时通过蒸汽加热器E001加热到70 oC段。按照一定比例,将磷酸加入酸混合器 并以一定的流量泵入该工M080并其中与油发生深度反应,然后混合物进入酸反应延时罐M084去。 ,从而确保非水化脂能够完全转化成可水化磷脂。这些物质与随后中和工艺中形成的皂脚一同被除
The acid conditioned oil is reacted with caustic soda solution injected at a controlled rate in the Neutralizing
Inter-Mixer M081 and the retention mixer M086. The lye neutralizes the free fatty acids and the excess of
mineral acid in the oil forming soapstock. In the retention mixer the oil is agitated very slowly in order to make
sure that the water-soluble gums form larger lumps. The oil/soapstock mixture flows from the retention tank by
pressure and is then heated in the heater E002. The soapstock together with excess caustic solution and
other impurities are removed in the Soapstock Separator S011.
酸调理后的油在中和混合器M081和延时反应罐M086离皂脂脚肪的酸混和合过物量从的延磷时酸反应,罐形中成压皂出脚来。,油随在后延在时加反热应器罐慢中速与搅按拌一混定合量,加让入磷的脂碱分液子进行充反分应吸水。凝碱聚液涨用大于中。和油游E002液、杂质一同通过脱皂离心机 中加热到离心分离所需的温度。皂脚与过量的碱S011除去。
For palm oil refinery, before the bleaching, normally it shall be acid conditioned. Here we include the possibility.
That is, when it is the palm oil physical refining, we use the long mix neutralization acid mixer for palm oil acid mixing.

PROCESS DESCRIPTION - BLEACHING 工艺描述-脱色
The plant is designed to continuously process neutralized soybean oil, rapeseed oil and crude palm oil
as per the attached flow diagram.
该工段用于连续加工碱炼后的豆油,菜籽油和毛棕榈油,具体工艺参见附后的工艺流程图. BLEACHING 脱色工艺
The degummed and neutralized oil is heated to 105篊 by deodorized oil in the Bleaching Economizer E600 or by steam in Bleaching Heater E601 during the start-up and enters the top compartment of the Bleacher B610 which operates under vacuum. Here it is dried and mixed with bleaching earth. The earth is automatically proportioned by the hermetic Earth Dosing System TD660 directly from the Earth Feed Hopper BT660 into the Bleacher via a duct located below the scrubbing section to prevent dust from entering the vacuum system. The Earth Dosing System is based on two automated butterfly valves with an intermediate dosing chamber. The valves are sequenced by an adjustable timer system in the control panel.
脱胶及中和后的油通过以脱嗅油为热源的节能器E600或在开车阶段以蒸汽为热源的加热器 E601加热到105oC,并送入处于真空状态下的脱色塔,B610土定量系统 的顶部。这里,油被干燥并与白土混和。白土通过密闭的白TD660,由白土日罐,BT660入真空。白土定量系统 自动按比例通过喷油口下的一根加料管加入,这样可以防止白土进TD660控制软件进行控制。 由两个碟阀和其间的一个计量室组成。自动阀门通过调定时经由
In the Bleacher, which is equipped with steam agitated compartments to ensure proper mixing and,retention time, the color bodies and oxidizing materials, etc. in the oil are
gradually absorbed by the earth.
与在白脱土色充塔分中混,油合中。的 氧化物等逐步被白土吸收。此罐配备有蒸汽搅拌器用于控制混合和反应时间,以保证油 FILTRATION 过滤
The oil/earth mixture is pumped through the Bleaching Filters F691/2 followed by the Polishing Filters,where the earth and solid impurities are retained. The bleached oil is then enter to the Bleached Oil TankT770, which acts as intermediate buffer of oil before deodorization. The Bleached Oil Tank is kept under,vacuum.
油/土混合油浆被泵入脱色过滤机F691/2和随后的抛光过滤器F681/2,待脱色油被送入脱色罐 , 在这里白土和固体杂质被除去,脱T770。该油罐为脱色油进入脱嗅工段的中间罐,此罐与真空连接。
The Bleaching Filters operate alternately so that one unit is always working while the other one is cleaned.The Bleaching Filter cleaning cycle consists of pressurizing the bleaching filter with steam until the main liquid volume has been discharged and then continuing the blowing via the steam blowing cyclone until the cake is properly de-oiled.

该工段用于连续加工碱炼及脱色过的豆油和菜籽油,具体工艺参见附后的工艺流程图. DEODORIZATION 脱嗅工艺
Bleached oil enters the plant via the Bleached Oil Tank T770 which also serves as a deaerator to remove air and moisture with the aid of vacuum. In order to speed up the startup, the oil is heated by steam in Bleached Oil Heater E701.
脱色油经脱色油罐T770,此罐也用作析气器以除去油中空气和水分。脱色油加热器E701 加热用,以提高启动速度。 作为装置启动时的
The deaerated oil is then first re-generatively heated by deodorized oil in the new type dome VHE。Economizer VHE703 and then by high pressure steam in the new dome type VHE Final Oil Heater VHE704 to deodorization temperature. The temperature is maintained by automatic control of the steam pressure in the High Pressure Steam Boiler G760. In VHE Final Oil Heater VHE704, the oil is heated under vacuum and
