Alfa Laval plate heat exchanger has always had a large share in the chemical industry, but in special working conditions, there are still some technical difficulties have not been broken through, non-purified brine salt production line is one of them.

Rupute received a more difficult working condition: the production line of non-purified brine salt production process has been suffering from serious scaling problems, leakage, corrosion and other problems have seriously affected the normal production; This is because there are more calcium and magnesium ions in the non-purified brine, and the scaling is mostly calcium sulfate. The scaling is rapid in the heat exchanger, and most manufacturers will adopt the brine purification, that is, the scaling phenomenon of the brine is removed first by adding drugs, and then the plate preheater is used, which increases the cost of salt production.

Qingdao Ruipute team of engineers, after the reception of the working condition of heat exchanger in materials industry combined with the team in recent 20 years of practical experience, from all the aspects of saving cost, solve the scale, leak, reducing corrosion, reduce teardown washing time, etc for the working condition of the proposed solution of plate heat exchanger was proposed to replace the pipe heat exchanger, titanium and titanium instead of palladium rationalization proposal, this for the first time in the salt brine purification production line in China.

From the completion of equipment production to the equipment entering into the production line, Rupert's engineer team and foreign supporting manufacturers jointly debugging for more than a month, to ensure the formal operation of the production line. Until today, the production line has been running normally for more than 1000 days! Save about 10 million yuan every year and save more than 50 million yuan in all aspects.

With nearly 20 years of experience in the specialty heat exchanger industry and a team of senior engineers, Qingdao Ruipute developed the first titanium plate heat exchanger for non-purified brine salt making process in China for the company, and this production line has also become the second non-purified brine production line in the world to operate successfully.
