Propylene vs Acetylene – Which is best?

When it comes to industrial cutting, heating, and brazing applications, the choice of fuel gas can make a significant impact on efficiency, cost, and safety. Traditionally, acetylene has been the go-to gas for oxy-fuel applications, but propylene is quickly gaining popularity as a superior alternative. If you’re looking for a cost-effective, safer, and high-performance cutting gas, here’s why propylene is the better choice over acetylene.

1. Lower Cost and Higher Efficiency

One of the biggest advantages of using propylene is its affordability compared to acetylene. Acetylene is more expensive to produce, store, and transport due to its unstable nature. In contrast, propylene is derived from natural gas and petroleum refining, making it more readily available and cost-efficient.

Additionally, propylene cylinders hold more gas per volume than acetylene cylinders, which means fewer refills and lower overall operating costs. This is a game-changer for businesses looking to maximize their budget while maintaining high performance.

2 Higher Cutting and Heating Capacity

Propylene has a higher BTU (British Thermal Unit) content than acetylene, which means it provides more heat energy per unit of fuel. This results in:

• Faster preheating times for cutting applications

• Deeper and cleaner cuts with reduced slag formation

• More efficient heating for brazing and welding tasks

Unlike acetylene, which has a narrow flame, propylene’s flame is broader and more evenly distributed, making it ideal for preheating large surfaces and ensuring even heat distribution.

3. Safer to use and store

Safety is a major concern when working with fuel gases, and this is where propylene significantly outshines acetylene.

• Lower risk of explosion: Acetylene is highly unstable and requires special handling. It must be stored in cylinders containing acetone and porous material to prevent decomposition. Propylene, on the other hand, is much more stable and does not require special storage conditions.

• No risk of dangerous decomposition: Acetylene can self-decompose under pressure, leading to explosions. Propylene does not have this issue, making it a safer option for workshops and industrial environments.

• No need for dissolved gas storage: Since acetylene is stored in acetone, improper withdrawal rates can cause the acetone to be drawn into the torch, leading to unstable flame performance. Propylene does not have this limitation.

4. No Cylinder Restrictions

Acetylene cylinders must be used in an upright position and cannot be used at high withdrawal rates, limiting flexibility in certain applications. Propylene can be used at any angle and allows for higher withdrawal rates, giving users more freedom and efficiency in their operations.

5. No Carbon build-up or soot

Acetylene flames tend to produce more carbon deposits and soot, which can contaminate the workpiece and require additional cleaning. Propylene burns cleaner, reducing the need for post-processing and improving overall work quality and efficiency.

6. Versatile Applications

Propylene is not only great for cutting and heating but is also widely used for:

• Flame brazing and soldering

• Metal preheating

• Plastic welding

• Shrink wrapping and flame straightening

Its versatility makes it an all-in-one fuel gas for various industries, from metal fabrication and construction to automotive repair and shipbuilding.

If you’re still using acetylene for your cutting and heating needs, it might be time to reconsider your fuel choice. Propylene offers a safer, more cost-effective, and higher-performing alternative without the risks and limitations of acetylene. With better efficiency, improved safety, and lower costs, propane is the smart choice for professionals and businesses looking to optimize their operations.

The Role of CO2 in Hydroponics: Boosting Plant Growth for Maximum Yield

The Role of CO2 in Hydroponics is to maximize your plant growth. While nutrients, lighting, and water quality often take centre stage, CO₂ is just as crucial in optimizing plant health and yield. In this blog, we’ll explore how CO₂ benefits hydroponic systems, the best ways to introduce it, and how it can help you achieve rent-free gas in your indoor growing setup.

Why Is CO₂ Important for Hydroponics?

Plants use CO₂ during photosynthesis, the process in which they convert light into energy. In traditional soil-based farming, CO₂ levels fluctuate naturally, but in an indoor hydroponic system, CO₂ can become a limiting factor, especially when plants are growing rapidly under strong artificial lighting.

When CO₂ levels are increased beyond the natural atmospheric concentration (which is about 400 ppm), plants can grow faster, produce larger yields, and even become more resistant to pests and diseases. Most hydroponic growers aim for 1,000 to 1,500 ppm of CO₂ in their grow space for optimal results.

Benefits of CO₂ in Hydroponic Systems

    1.            Faster Growth: With higher CO₂ levels, plants photosynthesize more efficiently, leading to quicker vegetative growth and earlier harvests.

    2.            Increased Yields: More CO₂ means plants can produce bigger fruits, flowers, and leafy greens.

    3.            Better Resilience: CO₂-enriched plants often show greater resistance to stress, including heat and pests.

    4.            Efficient Use of Light: CO₂ supplementation allows plants to make full use of high-intensity grow lights, improving energy efficiency.

How to Introduce CO₂ into Your Hydroponic Setup

There are several ways to add CO₂ to a hydroponic grow space, and choosing the right method depends on your setup and budget.

1. CO₂ Tanks and Regulators

The most common method is using compressed CO₂ cylinders with a regulator and timer system. This allows precise control over CO₂ levels, ensuring plants receive the optimal concentration without waste. As the areas largest Adams Gas Stockist, we have a wide range of sizes in stock for all your Hydroponic requirements and all completely rent free:

CO2 1.5 KG

CO2 3.15 KG

CO2 6.35 KG

CO2 15 KG

CO2 34 KG

2. CO₂ Generators (Burning Propane or Natural Gas)

CO₂ generators burn propane or natural gas to produce carbon dioxide. This method is ideal for larger grow rooms but produces heat, which must be managed with ventilation. If you’re using rent-free gas, this could be a cost-effective solution for maintaining high CO₂ levels.

3. Fermentation or Dry Ice

For smaller or budget-conscious setups, CO₂ can be introduced through fermentation (e.g., sugar and yeast) or using dry ice (solid CO₂ that sublimates into gas). While less controllable, these methods can still be effective for increasing CO₂ levels.

4. CO₂ Bags or Mushroom Cultivation

Certain CO₂ bags contain mycelium, which naturally releases CO₂ as it grows.

Calor Gas Cylinders Being Discontinued

Calor have announced that as of 1st February, they will be discontinuing the 3.9KG, 4.5KG & Cube Gas Cylinders from their range!

Why have they done this?

“Improving our cylinder service is a priority. Our existing range of cylinders is creating complexity within our supply chain. This means longer change over times and reduced filling capacity on high volume key sizes. That’s why we’ve taken the difficult decision to reduce our cylinder range, simplifying the business.

For any customers with these cylinders, we will be able to exchange them for alternative cylinders. For example those looking for a 3.9KG Propane will be offered a 6KG Propane, and those looking for a 4.5KG Butane will be offered the 7KG Butane.

As the Cube Cylinder was specifically designed for the Calor Cube Heater, there is sadly no alternative cylinder. Because of this we can either offer a refund in accordance with your Cylinder Refill Agreement, or £7.50 Inc. VAT if you don’t have your original paperwork (CRA)

We apologise for any inconvenience this may cause, but as always we will try to help wherever possible.

B&Q Supply Update

As of December 31st 2022, Calor will no longer be supplying any B&Q stores with their gas. This will mean that any customers who purchased a cylinder from either their Farnborough or Guildford branch will no longer be able to exchange it there.

As one of the areas leading Calor stockists, we will be liaising with Calor to ensure that we have a constant and reliable supply of their range coming into us. This will help to ensure that any customer seeking to exchange their empties for full ones, will not be disappointed.

We will also be increasing our stock of the 5KG Patio & 13KG Patio (Green) cylinders as we expect to see a significant increase in sales as the good weather starts to return.

The advice we always suggest to our customers is try and pre-order wherever possible to avoid disappointment.

If you have any questions please get in touch with us on 01252 540319.
