Inconel 600 Chlorination Reactor

Chlorination Reactor

When conducting chlorination reactions, the chlorination reactor is a critical apparatus to facilitate chemical reactions between chlorides and other substances. In the process of chlorination, chlorine gas or chloride compounds are typically introduced into the reactor, where they undergo chemical reactions with other reactants to generate the desired products. These reactions can be employed to synthesize various types of chemical compounds, including chemicals, intermediates, or other industrial products.

When it comes to chlorination reactors, specific cases and applications may include:

1. Preparation of Sodium Chloride: Sodium chloride (table salt) is a crucial product in the chlor-alkali industry. Chlorination reactors can be used to react hydrochloric acid with sodium hydroxide to produce sodium chloride.
2. Synthesis of Chlorides: Chlorination reactors can be employed to synthesize various chloride compounds, such as potassium chloride, ammonium chloride, and others. These compounds find multiple applications in the chemical industry and agriculture.
3. Organic Synthesis Reactions: In certain organic synthesis reactions, chlorination reactors can be utilized to introduce chlorine atoms, such as in the chlorination of aromatic compounds.
4. Chlorine Gas Oxidation Reactions: Chlorine gas oxidation reactors can be used to produce gases like nitrogen monoxide and nitrogen dioxide, which have significant applications in the chemical and environmental sectors.
5. Preparation of Metal Chlorides: Chlorination reactors can also be applied to prepare metal chloride compounds, such as aluminum chloride and magnesium chloride. These compounds play essential roles in metal refining and catalyst preparation.
6. Chloride Treatment and Recovery: Chlorination reactors can be employed to treat chlorinated waste materials, breaking down chloride compounds in organic waste into harmless substances and facilitating resource recovery.

Inconel 600 Chlorination Reactor

This equipment is a core unit in the process of methane chloride production, mainly using methanol and liquid chlorine as the primary raw materials to produce chloromethane through the methanol method. Its media consist of a mixture of hydrogen chloride QC+, methanol CQ3;Q, chloromethane CQ3C+, and chlorine gas C+”. It is a type III reaction vessel.

Inconel 600 Chlorination Reactor advantages

Inconel 600 alloy exhibits better oxidation resistance in a neutral medium compared to pure nickel, with oxidation resistance reaching temperatures as high as 1180°C. Due to its high nickel content, it displays excellent resistance to stress corrosion in both high-concentration chloride environments and caustic solutions containing OH-. Furthermore, its substantial chromium content contributes to its corrosion resistance in high-temperature oxidative media. Notably, it withstands dry chlorine gas and hydrogen chloride corrosion, withstanding temperatures of up to 650°C. As a result, Inconel 600 alloy is widely used in facilities exposed to high-temperature chlorine gas and hydrogen chloride. It is often employed as a substitute for industrial pure nickel in resisting corrosive alkalis and halogens at elevated temperatures.

Inconel 600 is easily cold and hot formed. Cold forming demonstrates work hardening, but cold rolling of cylindrical bodies poses no difficulties. Heads are formed using hot stamping, with the hot working temperature range being 870-1230°C for high temperatures and 470-550°C for low temperatures. It is advisable to avoid the heating temperature range of 650-870°C, where the material’s plasticity is relatively low. Prior to heating, all contaminants, especially sulfur, phosphorus, lead, and other low-melting-point metals, should be removed. Heating should take place in a weakly reducing sulfur-free atmosphere, with the content of hydrogen and carbon monoxide in the reducing atmosphere being at least 2%. For optimal temperature control and contamination prevention, it is recommended to use electric furnace heating, vacuum, or inert gas atmospheres. After sandblasting to remove the oxide layer, the stamped head is pickled in a solution of nitric acid and hydrofluoric acid. When cutting or forming, shear machines or plate bending machines should be wiped clean, and a thin austenitic stainless steel plate can be used as a cushion to prevent iron particles from being pressed into the surface and causing pitting corrosion.

Using an Inconel 600 Chlorination Reactor can meet the corrosion requirements of the methane chloride production process and media. Compared to equipment made from austenitic stainless steel, it can significantly extend the service life.
