Vacuum Evaporator Design and Operation

Vacuum Evaporator Design and Operation

+

In the early days of the vacuum process it was necessary to discharge the mother liquor and any build up of solid impurities in the vessels by "boiling out" which was done every few days. This reduced the time for salt making and, furthermore, led to a considerable discharge of brine to the adjacent canal or river. With modern plants, improved methods of brine purifiion and evaporator ...

The invention relates to a sea or lake salt water evaporation art. Particularly, the invention refers to a salt making process by using the beach field bittern, which is not resolarized, through direct vacuum evaporation. The bittern is separated during the production of crude salt and the bittern is discharged during the vacuum salt making process of saturated brine; the bittern is processed ...

Closed pan production under vacuum. The open pan salt works has effectively been replaced with a closed pan system where the brine solution is evaporated under a partial vacuum. Salt mines. In the second half of the 19th century, industrial mining and new drilling techniques made the discovery of more and deeper deposits possible, increasing mine salt's share of the market. Although mining ...

Most of the table salt in Europe, Australia, East Asia and the Americas is a product of vacuum pan refining; a process where water is evaporated from brine using steam or electricpowered vapour to recompress evaporators. Steam from boilers is fed from one evaporator to the next to increase energy efficiency and once the brine enters the crystallizer vessel, salt is precipitated. The ...

 · In the production of vacuum salt, the key factors that affect the vacuum degree are: the temperature of cooling water supply and the extraction amount of non condensable gas. In order to improve the vacuum degree, it is necessary to reduce the water temperature of cooling water and use a vacuum equipment with low steam consumption, high efficiency and large steam extraction capacity. .

The well produces highquality vacuum salt, using a borehole brine process. Following a collapse of the cavern formations, the outer 11 ¾" casing was sheared, creating a fish that completely isolated the cavern, thereby preventing salt production. In response, the operator planned an intervention to remove the fish by cutting the affected casing sections, and dropping the fragments into the ...
