Salt recovery from desulfurization wastewater
Thread Content
Is the process for extracting salts from desulfurization waste liquid complex? How are the workers performing in carrying out this task? Is there significant leakage?
Extracting crude salt involves using an evaporation tank to heat and concentrate the desulfurized solution with steam under vacuum conditions; by controlling the degree of concentration, this process can be carried out effectively

There are two methods for extracting by-products from coking desulfurization waste liquid: One is to extract crude salt, that is, to obtain a mixture of all salts without separating them individually. II. The extraction of refined salt involves separating thiosulfate and thiocyanate, with the contents reaching **the corresponding standards, thereby yielding a high added value. The first method is simpler, while the second method is more complicated. The entire process is theoretically simple, but it requires certain skills in practice
Our company is planning to install a desulfurization and salt extraction system, one that is used to extract sodium thiocyanate and sodium thiosulfate—these two types of salts. I’d like to discuss this in detail with everyone
Who has information on this topic? I’d like to know as well
The desulfurization and salt extraction process is not complicated in itself, nor is the workload for the workers very high. However, the demand for salt in the market is currently somewhat saturated; sodium thiocyanate has a better market price, while sodium thiosulfate does not
Extracting crude salt involves using an evaporation tank to heat and concentrate the desulfurization solution under vacuum conditions with steam; by controlling the degree of concentration, it is possible to obtain salt from the desulfurization waste liquid. Is the process for extracting salt from such waste liquid complex? How skilled are the workers required to operate this equipment? Is there significant leakage? I’m posting in the top comment! ~
Which engineering companies can take on projects involving the recovery of salts from desulfurization solutions on a turnkey basis?

This involved everything from the design of the process flow, to participating in the drawing design of the entire project by the design institute, to overseeing on-site construction management, equipment procurement and installation, and all the way to the final commissioning, staff training, and project acceptance.

Rather than spending money to hire someone to handle it as a whole, it’s better to find a company in this field and use an energy contract management approach, having them cover the costs of dealing with your waste liquids. Of course, you can discuss how to divide the profits among yourselves
