在基于伍德/Vinnolit沸腾反应器 (UVBR)技术中，EDC产品无需蒸馏，纯度便可达99.93%，可直接用作裂解制氯乙烯 (VCM)的原料。 另外与Vinnolit原有氯化工艺相比，UVBR可使能耗 (包括低压蒸汽、冷却水及用电)费用从约630美元/t EDC降低至250美元/t EDC，因生成副产物而导致的原材料损失从40美元/t降至5美元/t，设备投资费用减少15%-20%。 Vinnolit原氯化工艺是强制循环EDC，先溶解氯气，然后加入乙烯气体，吸收后与氯气进行反应。 而在新氯化工艺中，乙烯 …

The Vinnolit process for the production of vinyl chloride monomer (VCM) from ethylene and chlorine proceeds via two different routes. In the direct chlorination as well as in the oxychlorination process, ethylene-dichloride (EDC) is produced.

vcm由二氯乙烷(edc)热裂解生产，edc由乙烯和氯气生产。实际上所有vcm装置都与edc生产组合成一体化。全球约95%的edc用于生产vcm，几乎所有vcm用于生产pvc。ed

5 天之前 · 具有代表性的Inovyl公司的VCM工艺是将乙烯氧氯化法提纯的循环EDC 和来自直接氯化的EDC在裂解炉中进行裂解生产VCM。 经急冷和能量回收后，将产品中分离出HCl (HCl循环用于氧氯化)、高纯度VCM和未反应的 EDC (循环用于氯化和提纯)。

2023年12月1日 · Here we develop a mixed-integer linear optimization model, which we use to compare the cost and flexibility of the most relevant decarbonization options for the combined chlor-alkali electrolysis (CAE) and vinyl chloride monomer (VCM) production process.

2016年2月1日 · 全球约95%的edc用于生产vcm，几乎所有vcm用于生产pvc。 EDC的其他用途是用在氯化溶剂，如三氯乙烯、乙胺、亚乙烯基氯和三氯乙烷，也用于生产四氯乙烯的中间体和用作生产六氯代酚基甲烷的催化剂。

The five main processes used in the production of VCM are shown in Figure 1. The five processes include: direct chlorination of ethylene to form EDC, oxychlorination of ethylene to form EDC from recycled HCl and oxygen, purification of EDC, thermal cracking of EDC to form VCM and HCl, and purification of VCM.

Producing sales quality PVC from raw materials involves several steps. Initially, ethylene dichloride (EDC) must be produced from the feed stocks of ethylene and chlorine. The EDC is then thermally cracked to produce vinyl chloride (VCM), …

So far, thyssenkrupp Uhde has built plants with a total nominal capacity of more than 10 million tonnes per year of EDC and 6.5 million of VCM. thyssenkrupp Uhde’s share of the EDC market totals approximately 40 %.
