以下控制系統(tǒng)對(duì)于電解槽的可靠安全運(yùn)行非常重要。
5.5.1進(jìn)入電解槽的鹽水流量
進(jìn)入每臺(tái)電解槽的鹽水流量需要控制在1-2%變化范圍內(nèi)，維持通過(guò)每臺(tái)電解槽的減耗量不變，推薦使用自動(dòng)控制系統(tǒng)。
5.5.2 進(jìn)入電解槽的堿液流量

6. 電解車(chē)間建筑設(shè)計(jì)
6.1 單元槽組裝和維修區(qū)
必須為電解槽單元槽的現(xiàn)場(chǎng)組裝和維修提供充足的樓層面積和相關(guān)設(shè)施。在這個(gè)區(qū)域的主要操作是組裝含有預(yù)濕膜的單元槽和包括電極更新在內(nèi)的電解槽維修工作。在安裝進(jìn)電解槽之前，組裝好的單元槽同樣需要經(jīng)過(guò)壓力和泄漏測(cè)試。
以下規(guī)范必須在這一設(shè)計(jì)領(lǐng)域中堅(jiān)持：
1. 為組裝和測(cè)試所提供的樓層總面積至少要達(dá)到一百五十平方米的最低限度。然而，如果為了要趕上項(xiàng)目的建設(shè)目標(biāo)而需要以一個(gè)更快的速度來(lái)組裝單元槽，將會(huì)需要更多的面積。空間和布局必須在項(xiàng)目的起始階段通過(guò)Ineos技術(shù)來(lái)論證。
2. 即使是位于主要的電解車(chē)間內(nèi)，該區(qū)域的溫度也要保持在十五℃到三十℃之間，而且能夠自我控制。

5.5 Essential Control Systems
It is essential for reliable and safe operation of the Electrolysers that the following control systems are installed:
5.5.1 Brine flow to Electrolyser
Brine flows to each Electrolyser needs to be controlled within 1-2% variation, to maintain consistent depletion across each Electrolyser. Automatic control is desirable.
5.5.2 Caustic flow to Electrolyser
Recycled caustic flow to each Electrolyser needs to be individually controlled to permit fine tuning of the Electrolyser heat balance (outlet temperatures). Automatic control is desirable.
5.5.3 Brine feed temperature to Electrolyser
The temperature of the brine to the operating Electrolysers needs to be controlled by the feed brine heat conditioning system at a single point. In a multi-electrolyser cellroom the feed brine temperature to a single electrolyser going through it’s heating or cooling cycles must also be controlled
5.5.4 Caustic feed temperature to Electrolyser
The temperature of the caustic to the operating Electrolysers needs to be controlled by the feed custic heat conditioning system at a single point. In a multi-electrolyser cellroom the feed caustic temperature to a single electrolyser going through it’s heating or cooling cycles must also be controlled
5.5.5 Hydrogen / chlorine pressure & differential pressure control
It is essential that the pressure and differential pressure at the Electrolyser exit ports is automatically controlled, during all modes of operation (normal operation, start-up, shutdown etc.), according to the tight limits specified in sections 3 and 4.6. The main requirements and features of these control systems are detailed in section 4.6.
5.5.6 Demineralised water to catholyte circuit flow controller
It is essential that the demineralised water make-up flow to the common cellroom catholyte circuit is automatically controlled. The set point can be set by a DCS system (calculated to be proportional to the total load on all Electrolysers in the cellroom). 
5.5.7 HCl flow control for Feed brine acidification 
For Electrolysers employing feed brine acidification flow control is required for acid (HCl) feed to each Electrolyser / rectifier system. 
6. Cellroom Building Design
6.1 Module Assembly and Maintenance Area
Adequate floor space and the associated utilities must be provided for on-site assembly and maintenance of electrolyser modules. The main operations undertaken in this area will be assembling of modules with pre-wetted membranes, and Electrolyser repair work including electrode renewal. Assembled modules will also need to be pressure / leak tested before installation in the Electrolyser.
The following specifications must be adhered to in design of this area:
1. The total floor area provided for Assembly and testing should be a minimum of 150 m2. However, more area will be required if there is a requirement to assemble modules at a faster rate to meet project construction targets. The space and layout must be discussed with Ineos Technologies at an early stage in the project.
2. The area should be within the temperature range 15 - 30C and be self contained, even if located in the main cellroom.
3. The walls should be painted to provide a dust free environment. Adequate lighting should be provided.
4.The following services are required:
- Process wash down water
- Demineralised water.
- Oil free air for pressure testing of the assembled Electrolyser  (4 bar g)
