The application pertains to processes for producing components such as an alkali hydroxide and a carboxylic acid. The processes generally comprise reacting a component comprising calcium carbonate, or calcium sulfide, or calcium hydroxide, or calcium oxide, or calcium weak acid, or any combination thereof with a component comprising a carboxylic acid to form a component comprising a calcium carboxylate and a component comprising carbon dioxide, or hydrogen sulfide, or water, or any combination thereof. At least a portion of the formed calcium carboxylate is reacted with a component comprising an alkali sulfate to form a component comprising an alkali carboxylate and a component comprising calcium sulfate. At least a portion of the formed alkali carboxylate is electrochemically reacted to form a component comprising an alkali hydroxide and a component comprising a carboxylic acid.

Disclosed is a method for preparing ammonia gas through a reaction between an ammonium salt and a silicate. An aqueous solution of the ammonium salt in the form of atomized droplets is contacted with a silicate at a high temperature for a reaction to generate ammonia gas and a solid substance. The silicate can be solid particles, and forms a bed. The generated ammonia gas is collected, the solid substance is extracted, part of the same solid substance is mixed with a fresh silicate solid particle, and the mixture continuously reacts with the atomized droplets of the aqueous solution of the ammonium salt.
