Following points are to take into consideration:
! The minimum filling level and the dimensions of the tank are important for the system. The
crown of the lance need not touch the floor of the tank, but it has to be submerged in the medium. Rising bubbles are important for getting the stir effect in the tank. The lance only has to have contact with the tank floor if the diameter of the tank exceeds its height by a factor of more than 1.5.
! The relationship between the quantity of the medium and that of the acrylic acid is essential.
Additionally, it is important to allow time for the homogenisation of the medium and the
acrylic acid. Please refer to the BASF brochure in order to calculate the quantity of the medium. When the customer has determined the correct quantity of the medium, we make available the corresponding gas quantity in a N-bottle.

Lance: The lance consists of 5 telescopic tubes and one jacket tube. Five tubes extend when the release piston unclamps. The telescope extends up to 10 m. The wire in the lance allows the tubes to retract into their set-up position.
The body of the lance is made of 1.4571 stainless steel (similar to 316 Ti). The sealings and gliss elements are made of PTFE. EPDM-O-rings are only integrated into the release system. The crown consists of a REMBE rupture disk and a homogeniser for diffusing the gas bubbles. Inside of the homogeniser there is a black PA-plate in order to protect the rupture disc from dirt.

? is equipped with the rupture disc and the crown, it is
installed on the top of the tank with a swivel-flange DN100 and connected to a 1-inch feed line for the RESTAB ?-medium.
RS Ingenieurtechnik GmbH can offer special reducers for assembly.
Please note that the extension length of the TEL? from flanged union to bottom edge of the crown amounts to ten metres. Parts which obstruct the moving of the TEL? could be damaged. Additionally, ensure that the TEL?
can immerse into the medium at the minimum filling level.
The function of the RESTAB? system is to homogenize the RESTAB? medium with acrylic acid in the tank to avoid dangerous incidents caused by uncontrolled polymerisation in the tank.
To release the TEL?, open the valve of the nitrogen bottle completely and position the RESTAB? container near the feed line. With a clockwise turning motion then couple the female part of dry disconnect coupling (DDC?) which is connected with the RESTAB?-supply unit, to the DDC? male part of the feed line.
The next steps run automatically:
The nitrogen presses the RESTAB? medium into the feed line until 2,5 bar pressure is reached. At 2,5 bar feed pressure a piston valve releases the telescopic unit of the TEL?. The telescope extends until self-locking up to
10 metres. The duration of the process from release to self-locking is about 1.5 min. After self-locking of the telescope pressure in the TEL? rises fast to 3.5 bar and the rupture disc opens. Now the RESTAB ? medium driven by nitrogen is injected into the tank and is homogenized with the acrylic acid.
Please take care that the entire content of the nitrogen bottle is emptied into the tank. This ensures the best homogenisation of the RESTAB?
medium with the acrylic acid.

www.seliger.deAcrylic acid is often used in the manufacture of chemical products. Acrylic acid is not a harmless substance. An unwanted polymerisation of larger quantities can take place with explosive violence. For that reason the measures taken to prevent just such a reaction during storage are correspondingly comprehensive.
In order to further improve safety (but not as a replacement for the measures that are otherwise required), a system to restabilise incipient reactions in a storage tank was developed (the
RESTABTM
system) under the auspices of a leading chemicals company.
The RESTABTM
system primarily consists of the following components:
- mobile tank with the RESTABTM
liquid (phe-nothiazine in a patented carrier medium)- nitrogen bottle the nitrogen is used to extend the telescopic lance, to convey the Restab liquid, and to provide good mixing - The DRYDISTM
dry disconnect coupling to quickly couple the mobile tank to the storage tank in question
- Fireproof piping or a hose to the roof of the tank
- The telescopic lance TELTM
to inject the
RESTABTM
liquid
The telescopic lance is attached to a flange in the cover of the tank. In normal operation the retracted telescopic elements are within the gas area of the tank. If the need arises, the operator couples up the mobile tank to the fireproof line by means of a dry disconnect coupling.
Then the nitrogen inlet opens. The following process takes place automatically after that: The pressure in the mobile tank rises to about 1 bar. Now a rupture disk in the tank outlet
opens and the RESTABTM
liquid flows through the feedline up to the lance. The pressure in the system rises to 3 bar. This pressure moves a piston which opens up the passage to the telescopic tubes and unlocks the tube. The lance is extended. The pressure rises up to 4 bar after it has extended. The rupture disk at the end of the lance opens at this pressure and
the RESTABTM
liquid is injected into the tank. The nitrogen is ejected evenly during the flushing phase by means of the crown at the end of the lance and thus promotes thorough mixing.
The extended length of the telescopic lance is 10m. If the tank height is less, the lance is set down on the floor of the tank without this
affecting its functioning. Once the RESTABTM
liquid has been injected, the lance is brought back to the starting position by means of a crank handle and a wire cable fixed within the telescopic part.

一、基本情况:
该罐容积500m3~常压。爆炸前~留.7%液位~折0t丙烯酸。丙烯酸闪点4?~易自聚~聚合热为16kcal/mol~添加阻聚剂,对羟基苯甲醚,
二、事故原因简要分析:
1、阻聚剂逐渐消耗的危险认识不足
当其00ppm、温度为50?时~每天丙烯酸的二聚体增加0.25 %~阻聚剂将随之缓慢减少
阻聚剂消耗~提升了丙烯酸自聚放热导致最终爆炸条件
2、停供储罐冷却水的后果估计不够
丙烯酸生产装臵停产检修~公用工程供应该罐的冷却水也被停用~致使该罐不能有效撤热
停供冷却水~削弱了丙烯酸储存的工艺控制手段
3、对待温度升高、超标报警的工艺异常处臵~完全处于失控是该罐爆炸的主要致因
1
工艺控制指标205?~报警设定值上、下限为30?8?。有章不循~视而不见~听而不闻~随之任之
三、事故教训:
1、《停产方案》制定~存在明显缺陷

一、工程概况
本工程原料罐区包含 4座 247 m3拱顶储罐(T-7001、 T-7002、 T-7003、 T-7009) 、 4座 134m 3拱顶储罐(T-7004、 T-7005、 T-7006、 T-7007) 。脱盐水罐区 1座 247m 3拱顶 储罐(T-7008) 。消防罐区 2台 7000m 3消防储罐 (438-1a 438-1b)
消防罐区 2台消防罐材质为碳钢 , 原料罐区 9台罐,材质均为 S30408。
原料罐罐体壁板 δ6,罐板间对接连接要求内壁平齐,罐顶为搭接连接﹑罐底中幅 板为搭接连接,壁板与底板大角焊缝处 300mm 加垫板对接连接。对罐体制作几何尺寸, 焊缝成形有较高要求,施工中应按图纸和各项规范标准要求,严格管理,严格施工。 主要工程量:

三、施工部署
1、部署原则
1)加大施工前期准备工作的力度,组织人员进点,进行技术准备、施工规划、临 时暂设施工,并陆续组织人员分期、分批进点。按施工程序组织施工,确定主要控制 点,施工人员要根据现场的条件分期分批到位,讲究实效,提高施工效率。
2)按多班次平行流水作业的施工原则组织施工,加快施工进程。
3)施工中采用网络计划管理和目标管理,加强计划性,强调专业工种协作配合, 安排好交叉作业施工。加强管理,杜绝野蛮施工,特别注意要始终抓好现场的安全和 文明施工。
