Calcium Oxide (CaO) is commonly referred to as quicklime. Calcium Oxide is a high calcium derivative of Calcium Carbonate, or limestone. Calcium Oxide is produced by heating Calcium Carbonate to very high temperatures, which causes the Carbon Dioxide to separate as gas from the Calcium Carbonate.
CaCO3 + HEAT → CaO + CO2
Hydrated Lime (Calcium Hydroxide (Ca(OH)2), or slaked Lime, is an inorganic mineral compound mined from the Earth. To form Hydrated Lime, Calcium Oxide (CaO) reacts with water to form a white powder, containing less than 1% moisture.
CaO + H2O → Ca(OH)2

Calcined Magnesium Oxide is used in a wide variety of industrial applications, such as Pulp and Paper, Water Treatment, Animal Feed, Epsom Salts, Soil Remediation, Flue Gas Desulfurization, and the Food and Beverage industry. W.K. Merriman can supply several grades of MgO suitable for all of these applications.
In the water treatment industry, Magnesium Oxide can be used for various applications. It is an effective base, which offers a safe method of pH control in comparison to other neutralizing agents such as Caustic Soda which is hazardous. It can also be utilized as a dry Magnesium Oxide powder, or converted to Magnesium Hydroxide for additional uses. Magnesium Oxide can create denser sludge, improve metals removal, and is safe for workers.
More than 80% of all Ferric Chloride is sold in municipal bids, with 53% sold for municipal wastewater applications, and 37% for potable water treatment applications. Industrial water treatment applications account for 6% of consumption, with the remaining 5% sold in non-water treatment applications, such as electronic and photographic etchants, metal surface treatment, and as a catalyst. Much of the etchant activity has moved to Asia. Electronic applications, especially for PCBs, are small in the United States.

Caustic Soda has a wide variety of applications based primarily on its ability as a strong alkali to react with many substances. It is a globally used product in which international consumption can affect the domestic supply and demand.
The largest uses for Caustic Soda are pulp and paper manufacturing, alumina production, de-inking of waste paper, water treatment, and general chemistry. Caustic Soda is a basic feedstock in the manufacturing of a wide range of chemicals. It is used as a raw intermediate and a reactant in processes that produce solvents, plastics, synthetic fibers, bleach, adhesives, coatings, herbicides, dyes, inks, and pharmaceuticals such as aspirin. It is also used in soap and detergent, oil and gas, and textile industries as well as to neutralize acidic waste streams and the scrubbing of acidic components from off gases. Possible uses are:
It is a strong, colorless alkali. Caustic Soda is manufactured through the electrolysis of Sodium Chloride (NaCL2, salt brine).
Along with Chlorine, Sodium Hydroxide is produced through the Chlor-Alkali electrolysis process. Electrolysis is an electrochemical reaction using a direct current to drive the decomposition reaction of an aqueous solution of Sodium Chloride (salt water) into Sodium Hydroxide, Chlorine, and Hydrogen Gas.
2NaCl + 2H20 → CL2 + H2 + 2NaOH
The type of cell technology and design affect the specification and product characteristic of the Sodium Hydroxide produced. The most common and primary cells used are Diaphragm Cell and Membrane Cell. There are limited Mercury Cell units still used in production today, as that is Cell production process is being phased out domestically and internationally.
The resulting Sodium Hydroxide solution through a Diaphragm Cell unit is 10-12% and contains Sodium Chloride (salt) which has been transported through the diaphragm. This solution is then concentrated by evaporation to final product strength of 50% Sodium Hydroxide and about 2% Sodium Chloride.
The Membrane Cell differs from Diaphragm in that the Cell produces 32% Sodium Hydroxide and contains significantly less Sodium Chloride in the final solution. The 32% Sodium Hydroxide produced from the Cells is then concentrated to 50% through evaporation.

Hydrochloric Acid (HCl, Muriatic Acid) is a major industrial chemical. It’s uses include: pickling and cleaning of steel, manufacturing of inorganic and organic chemicals; acidizing of oil wells to stimulate production; pH control of processes of effluents; production of sugars, starches, and other food products; production of organic dyes and pigments; ore beneficiation; catalyst reclamation; industrial cleaning; and concrete finishing.
The largest merchant sources of HCl are produced as a by-product from the process of chlorination of various intermediates such as Methylene Diphenyl Diisocyanate (MDI) and Toluene Diisocyanate (TDI). Fluoropolymer and Herbicides and other processes also contribute but with less excess Chlorine. Fluoropolymers are a major contributor to the production of products such as Teflon.
The balance of HCl is produced by the burning Chlorine in the presence of Hydrogen to manage the excess Chlorine produced. In general, this is performed in a strict manufacturing process of “burning” Hydrogen and Chlorine to produce high quality HCl. Overall this is known as the Chlor-Alkali industry. This process is widely used to produce Chlorine, Caustic Soda, and other Chlorine and Sodium derived/based products such as Sodium Hypochlorite (bleach), HCl, bleaching power, and Polyaluminium Chloride (PAC).
The process uses brine (salt water, NaCl + H20) during electrolysis to produce these products that are known as Chlor-Alkali market products.
2NaCl + 2H20 → Cl2 + H2 + 2NaOH
The burner acid is produced from the Chlorine and Hydrogen from the Chlor-Alkali process to provide a reliable supply of high quality, pure acid. Hydrogen and Chlorine are passed through a burner nozzle and ignited in a combustion chamber to produce clean, high quality gaseous Hydrochloric Acid.
H2 + CL2 → 2HCl
Storage and Handling
**An HCl vent scrubber should be used to absorb the gases generated during the unloading process. The gases in contact with the scrubber media are absorbed. The scrubbing liquid will need to be drained and neutralized. A regular scrubber maintenance schedule is highly recommended Tank fluid level measurement device and discharge line.
**The size of vent and overflow lines should be larger or equal in size to the filling lines.
Since HCL is highly corrosive to all tissue, the utmost care must be taken to prevent any HCl liquid or gas contact with eyes, skin, or clothing. Provide adequate ventilation and avoid breathing mist or vapor. A readily accessible and well-marked eyewash fountain and safety shower should be available in any area where HCl is handled.

Sulfuric Acid is an irreplaceable constituent of countless industrial processes that includes the manufacturing of fertilizer, paints and pigments, explosives, pulp and paper, plastics, detergents, textiles, batteries and a variety of specialty chemicals. Its properties of acidity and reactivity, it Sulfur content, and it’s affinity for water play essential roles in the manufacturing of a broad range of products.
Our key priority is being a safe, reliable supply of Sulfuric Acid complimented by value added services that enable us to deliver more than just H2SO4.
Metallurgical manufacturing is the primary source that co-produces Sulfuric Acid that we market within the United States. It all begins with the roasting and smelting of Nickel, Zinc, Copper, and Lead. These minerals are found naturally in the form of Sulfide ores such as Copper Sulfide. Following concentration of the mined ores, the first step of metallurgical refining is the removal of the Sulfur content. Heating the concentrated ore liberates Sulfur in the form of Sulfur Dioxide gas (SO2). If not captured and removed, SO2 can contribute to the formation of acid rain. The SO2 is captured and converted to Sulfuric Acid. Sulfuric Acid production at smelters is the direct result of emission controls designed to protect the environment.
Generally, smelter acid plants are comprised of three major stages (1) the gases are first thoroughly clean in the gas cooling and cleaning section, mist precipitators complete the gas cleaning, enabling an estimated 99.99% removal efficiency for most of the impurities present. (2) A large blower draws the clean gases to the conversion section (3) finally, the conversion and absorption stage where the Sulfuric Acid is actually produced. This final step is the oxidation of Sulfur Dioxide (SO2) to Sulfur Trioxide (SO3), which is then combined with water creating a 98% (H2SO4) Sulfuric Acid.
Sulfuric Acid is also produced through the burning of Sulfur process where elemental Sulfur is oxidized to provide the feedstock for acid production.
