The 2 types of demulsifiers stated are represented by the substances extra. They disclosed that Together with the LMW chemical additives, the normal age separation without any further chemical substances is 21.five% of h2o right after 30 min, which reduce the separation. Aside from that, the addition of HMW chemical additives exhibits an even bett
