Presence of ethylene in amounts ranging from a few parts per billion ppb to a few parts per million ppm can reduce plant vigour, decrease life of various plant parts and reduce stock quality. Any closed environment, such as truck trailer, shipping container, warehouses and cold rooms, will have a similar effect resulting in increased concentration of Ethylene. At the latter part of post-harvest, artificial ripening by using ethylene is general practice as it ensures that the produce reaches the consumers retail outlets with a degree of ripeness, which brings out its best in terms of taste, color, texture and nutritional value.
However these conventional methods adopted by most warehouses and cold stores of lowering the temperature and humidity and using gases like nitrogen and sulphur increase the shelf life but have several disadvantages. Refrigeration and humidity control slows decay but is not enough to halt the production of ethylene gas in cold stores and warehouse.
Even small amount of ethylene gas during storage is enough to hasten the process of decay of fresh produce. Controlled Atmosphere Storage CA — The concept of controlled atmosphere CA storage of horticultural products is based on the control of two major factors affecting plant aging. Controlling ethylene gas will maintain the quality and extend the life of horticultural products, allowing them to be stored for a much longer period of time. While refrigeration and humidity control will slow ripening and decay, they will not halt ethylene control.
However it is necessary to ensure the following:. However because of temperature and humidity concerns, makeup dilution air is typically drawn from the refrigerated area surrounding the ripening room.
Related Supply Modes Air Liquide packages ethylene pure gases and gas mixtures in a variety of high-pressure stainless steel cylinders and nonreturnable Mini-Mix Transportable cylinders, depending on the grade of pure gas or composition of the gas mixture and your application.

And the hits kept coming. By the end of February, prompt ethylene was on sale for less than 14 cents and buyers were not interested — even at these prices.
Ethane held steady at 15 cents per gallon — or 5 cents per pound — so at least margins were not under water in February. Throw in the COVID coronavirus and panic in oil markets that brought crude prices to lows not seen in decades and, well Ethylene prices have fallen in line with energy, fuels and NGLs, and, as of March 25, were sitting at an all-time low of 10 cents. Meanwhile, ethylene is only as strong as its weakest fundamental and with dozens of downstream chemicals making up the demand side, ethylene is impacted by a myriad of nuances in diverse markets.
And while ethylene itself has been exported, the volumes are a tiny part of the supply-side picture. And when you depend on the rest of the world for your demand, the story gets more complex. No one building a world-scale olefins plant in the past five years would have planned for the recent trade wars with China and attendant tariffs , nor the coronavirus epidemic that had all but shut down Chinese manufacturing.
No upside is predicted while the situation in China is playing out.
