5.5.1進入電解槽的鹽水流量
進入每臺電解槽的鹽水流量需要控制在1-2%變化范圍內，維持通過每臺電解槽的減耗量不變，推薦使用自動控制系統(tǒng)。
5.5.2 進入電解槽的堿液流量
循環(huán)的堿液流量需要個別控制，確保電解槽熱平衡（排出口溫度）的有效調節(jié)，推薦使用自動控制系統(tǒng)。
5.5.3進入電解槽的進料側鹽水溫度
進入運行中的電解槽鹽水溫度需要通過進料口鹽水單點溫度調節(jié)系統(tǒng)來控制，在有多用型電解槽的電解車間中，需要控制進入單獨的電解槽，參與加熱或冷卻循環(huán)的進料口鹽水的溫度。
5.5.4進入電解槽的進料側堿液溫度
進入運行中的電解槽堿液溫度需要通過進料口單點堿液溫度調節(jié)系統(tǒng)來控制，在有多用型電解槽的電解車間中，需要控制進入單獨的電解槽，參與加熱或冷卻循環(huán)的進料口堿液的溫度。
5.5.5氫氣/氯氣壓強和差壓控制
關鍵在于，在電解槽出口孔的壓強和差壓，根據(jù)第3節(jié)和第4.6節(jié)中明確的嚴格限制，在所有模式的運行中（正常運行、開車、停車等）都是自動控制的，這些控制系統(tǒng)的主要要求和特點在第4.6節(jié)中有詳細敘述。
5.5.6 進入陰極液的軟水流量控制
關鍵在于，進入共同電解車間的脫鹽睡補水流量是自動控制的，設定值可以由DCS系統(tǒng)進行設置（通過計算與電解車間中所有的電解槽的總負荷量成一定比例）。
5.5.7進料側鹽水酸化中的鹽酸流量控制
鹽水酸化流量控制對于進入每一臺電解槽 或整流器系統(tǒng)的酸（鹽酸）都是必須的。
6. 電解車間建筑設計
6.1 單元槽組裝和維修區(qū)
必須為電解槽單元槽的現(xiàn)場組裝和維修提供充足的樓層面積和相關設施。在這個區(qū)域的主要操作是組裝含有預濕膜的單元槽和包括電極更新在內的電解槽維修工作。在安裝進電解槽之前，組裝好的單元槽同樣需要經過壓力和泄漏測試。
以下規(guī)范必須在這一設計領域中堅持：
1. 為組裝和測試所提供的樓層總面積至少要達到一百五十平方米的最低限度。然而，如果為了要趕上項目的建設目標而需要以一個更快的速度來組裝單元槽，將會需要更多的面積�？臻g和布局必須在項目的起始階段通過Ineos技術來論證。
2. 即使是位于主要的電解車間內，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。
3. 墻壁應該被涂漆用以提供一個無塵的環(huán)境。應該提供充足的照明。
4. 以下服務時需要的：
- 處理洗滌產生的水
- 去礦物質化的水。
- 無油空氣下的已組裝電解槽的壓力測試（4bar g）
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)
