Has anybody experience in auditing coal based vinyl chloride production plant to improve process control, minimize energy consumption and reduce emissions? Can you kindly provide papers, checklists, case studies?
Good morning Mr. Fresner, I would give you a small help in your study by suggesting you to look for two different processes: 1. ethylene production from coal; 2. vinyl chloride production (that is mainly from ethylene). I don't know if there is any producer to integrate these two different industrial processes. Vinyl chloride is traditionally produced either by ethylene gas chlorination, or by oxychlorination. I looked for some articles and all of them present exclusively these ways of conversion. They are very cheap, therefore no one other method is better for economical aspects. To get ethylene there is a lot of literature about methods, also coal gaseification (via synthesis gas or directly by Fischer-Tropsch process or even via methanol from coal). But I know this is a completely different technological process, maybe nowadays somebody has integrated both process lines (coal to ethylene and further to vinil chloride monomer). I see there is a lot of documentation available about these two synthesis technologies, I didn't select any paper since you maybe have already saved the same doc. I think you will find easily also data regarding environmental aspects, processes efficiency etc. if look for the 2 separated processes to be integrated into a global process.
Regards.
Dear Mehmet, most we need material and energy balances of actual plants producing PVC from coal, indicating also the use of catalyst and losses of catalyst
best regards
Johannes
