Embodiment Construction

[0043] In this detailed description, the invention relates to the evaluation of liquid waste containing liquid and solid components obtained during the production of soda ash by the ammonia-soda process for the production of brine in underground caverns 1, illustrated by examples, the implementation The examples are just for easier understanding of the present invention, without any limiting effect.

[0044] Liquid wastes containing both liquid and solid components are generated during the application of the ammonia-soda process and generally originate from the following process sections. These craft parts are:

[0045] 1. The saturated brine used in the ammonia-soda method is first passed through calcium hydroxide (hereinafter referred to as milk of lime) and then refined with soda ash. As a result, the calcium (Ca) and magnesium (Mg) contents of the brine are reduced to desired levels. The process is realized in conical strippers and refining tanks.

Abstract

The invention relates to application of liquid waste containing liquid and solid components obtained in the process of producing sodium carbonate by adopting an ammonia-alkali method in the productionprocess of underground cave brine. Correspondingly, the invention provides application of liquid waste containing liquid and solid components obtained in the soda ash production process in the salinewater production process of the underground cave (1). Thus, recovery of soda ash and saline water mixed with a small amount of waste and recovery of liquid waste containing liquid and solid components obtained in the soda ash production process are provided.

Description

technical field [0001] The present invention relates to waste sludge obtained from the brine refining process, waste water obtained from the furnace gas cleaning section, deep blowdown of reverse osmosis process waste water cooling towers, and any type of washing waste water and distillation waste discharged from equipment in the production of soda ash by the ammonia-soda method , Evaluation of brine production applications in subterranean caverns. [0002] The invention relates to the recovery and utilization of solid and liquid waste produced during the application of the ammonia-soda method and its application in brine production. Background technique [0003] Brine is one of the important raw materials to determine whether the ammonia-soda method is economical or not. Procuring brine in an economical way is the first step in calculating the cost of soda ash production. [0004] It is known from the literature that there are two methods for the production of brine in th...
