Why Gastek

Ammonia cracking is a process gas package, not just a furnace in a catalogue.

Buyers need a practical decision between cracked ammonia gas, HNx, nitrogen-hydrogen blends, and purified hydrogen. Gastek's advantage is the combination of gas generation, protective atmosphere, hydrogen purification, controls, commissioning and service experience.

Ammonia cracker exports

Project experience includes ammonia cracker and PSA gas generation packages supplied to steel and industrial buyers in Egypt, Iran, and North America.

Float glass experience

Gastek project references include ammonia cracker units for float glass applications operating for more than 15 years.

Metallurgy and HNx background

Ammonia cracking sits next to Gastek's steel, heat-treatment, HNx protective gas, hydrogen, and nitrogen generation work.

System-level responsibility

The buying decision includes furnace package, purifier, instrumentation, safety, controls, commissioning, and after-sales support.

Industrial ammonia cracking technology

Specify the ammonia cracking unit from the gas duty and downstream process.

The important question is not only capacity. The right ammonia cracker depends on gas composition, temperature, catalyst duty, dew point, residual ammonia, pressure, use-point distance, controls, safety and whether purified hydrogen is required.

Ammonia cracking produces hydrogen-rich H2/N2 gas. Pure hydrogen requires an additional purification discussion, not just a different label.

Ammonia feed preparation

Liquid or gaseous ammonia is supplied from cylinders, tank, or existing storage and controlled before entering the cracking furnace.

Catalytic cracking furnace

Ammonia passes through a heated catalyst bed, typically around 800-900 C, where NH3 dissociates into hydrogen and nitrogen.

Cooling and gas conditioning

The hot cracked gas is cooled and conditioned before use so the downstream process receives stable H2/N2 gas.

Drying and ammonia removal

Purifier and dryer stages are selected where dew point and residual ammonia need tighter control for the furnace or process.

Use-point supply or H2 purification

Most applications use dissociated ammonia gas directly. Where high-purity hydrogen is required, a PSA purification stage can be reviewed.

Application Map

Ammonia cracker applications are decided by atmosphere chemistry.

A bright annealing furnace, steel line, glass process and PSA hydrogen purification package all need different gas quality, controls and safety assumptions. The ammonia cracking route should be selected around the process, not only the industry name.

What cracked gas solves

Reduce

Create hydrogen-rich reducing atmospheres for annealing, brazing, sintering, and selected furnace duties.

Protect

Technical specification

A good ammonia cracker proposal defines gas quality, not just nominal capacity.

A project engineer needs to know what gas is produced, what conditioning is included, how dry the gas must be, whether residual ammonia matters, and whether the downstream plant needs direct cracked gas or purified hydrogen.

Configuration factors

The right package is application-specific.

Industrial ammonia cracking has to be matched to the furnace, line, glass process or purification skid receiving the gas.

Gas composition

The standard cracked gas is hydrogen-rich H2/N2, not pure hydrogen. This must be matched to the process recipe.

Dew point and residual NH3

Dryer and purifier selection depends on the acceptable moisture level and residual ammonia limit at the use point.

Flow and pressure

Capacity should be sized from continuous demand, purge events, pressure drop, receiver storage and peak use.

Furnace duty

Heat-treatment and glass applications should define furnace type, operating hours, temperature and atmosphere quality.

Safety package

Ammonia and hydrogen require correct leak detection, ventilation, purge logic, ESD, relief and operator training.

Purification route

If the buyer needs high-purity H2, the cracked gas can be evaluated as feed to a PSA hydrogen purification package.

Clear route selection matters: direct cracked ammonia gas is different from pure hydrogen, and both should be specified from the actual process requirement.

PSA hydrogen purification

When cracked ammonia gas is the feed route, purification is a separate engineering decision.

Many furnaces can use H2/N2 dissociated ammonia gas directly. Other processes need a higher-purity hydrogen stream. In those cases, the cracked ammonia package should be reviewed together with residual ammonia removal, drying, PSA hydrogen purification, recovery and downstream pressure needs.

Use the correct route language

Direct ammonia cracker output: H2/N2 cracked gas. Optional downstream package: purified H2 from cracked ammonia feed gas.

Direct cracked gas use

Best when the furnace or atmosphere process needs hydrogen-rich H2/N2 gas rather than pure hydrogen.

Heat treatment

Bright annealing

Brazing and sintering

Glass atmospheres

Purified hydrogen route

Reviewed when cracked ammonia is used as the hydrogen source but the process needs higher H2 purity.

Purity target

Impurity limits

Recovery target

Pressure requirement

Safety and quote basis

The enquiry should define process gas demand, ammonia handling and hydrogen safety together.

Ammonia crackers involve both ammonia and hydrogen-rich gas. A serious proposal should address site layout, ventilation, purge logic, leak detection, use-point requirements and operator training before reducing the discussion to a price per capacity.

Ammonia Cracker FAQ

Questions buyers ask before specifying an ammonia cracking unit

What is an ammonia cracker?

An ammonia cracker, also called an ammonia cracking unit or dissociated ammonia gas generator, thermally decomposes ammonia over a catalyst to produce a hydrogen-rich gas mixture. The standard cracked gas is approximately 75% hydrogen and 25% nitrogen.

Is an ammonia cracker the same as a pure hydrogen generator?

No. The direct output from an ammonia cracker is H2/N2 cracked ammonia gas. It is useful for many protective and reducing atmosphere applications. If the process needs high-purity hydrogen, a downstream purification package such as PSA hydrogen purification can be reviewed.

Which industries use ammonia cracking units?

Common industrial uses include heat treatment, bright annealing, brazing, sintering, metallurgy, steel processing, float glass, specialty glass, HNx or protective atmosphere systems, and selected hydrogen-rich process gas applications.

What gas quality should be specified for an ammonia cracking unit?

Buyers should specify flow rate, outlet pressure, dew point, residual ammonia target, acceptable impurities, operating hours, duty cycle, and whether the process needs direct cracked gas or purified hydrogen.

Can cracked ammonia gas be purified to hydrogen?

Yes, cracked ammonia gas can be evaluated as a feed stream for hydrogen purification when the use point needs higher hydrogen purity. The final package depends on H2 flow, purity target, impurity limit, pressure and recovery expectation.

What safety items matter for ammonia crackers?

The design discussion should include ammonia handling, hydrogen safety, leak detection, ventilation, purge logic, ESD, pressure relief, safe venting, instrumentation, site layout, commissioning and operator training.

What information does Gastek need to size an ammonia cracker?

Useful inputs include application, cracked gas or H2 flow, pressure, dew point, residual NH3 target, purity requirement, operating schedule, ammonia source, site utilities, safety constraints and installation location.
