More DetailsAn Ethylene Plant is a process for the produc-tion of polymer grade ethylene (99.9 vol %). It also produces major byproducts such as propyl-ene (chemical or polymer-grade), a butadiene rich C 4 stream and C 6-C 8 aromatics rich pyroly-sis gasoline. The Ethylene Plant is the major supplier of feedstock to the polyethylene plants
More Details· Ethylene is a gaseous phytohormone and the first of this hormone class to be discovered. It is the simplest olefin gas and is biosynthesized by plants to regulate plant development, growth, and stress responses via a well-studied signaling pathway. One of the earliest reported responses to ethylene is the triple response.

More DetailsEthylene (C2H4), the chemically simplest plant hormone, is among the best-characterized plant growth regulators. It participates in a variety of stress responses and developmental processes. Genetic studies in Arabidopsis have defined a number of genes in the ethylene signal transduction pathway. Is …
More DetailsBeing continuously exposed to variable environmental conditions, plants produce phytohormones to react quickly and specifically to these changes. The phytohormone ethylene is produced in response to multiple stresses. While the role of ethylene in defense responses to pathogens is widely recognized, …
More Details· Abstract. Ethylene, a gaseous plant hormone, influences plant growth, development, and response to various stresses and pathogen infection. Ethylene is synthesized from S-adenosylmethionine (SAM) via 1-aminocyclopropane-1-carboxylic acid (ACC) plants, ACC synthase (ACS) and ACC oxidase (ACO), two key enzymes in the ethylene biosynthetic pathway, are tightly …
More Details· Ethylene is the "silent killer" in floriculture. It is a gaseous plant hormone that is colorless, odorless and is present at undetectable levels in normal atmosphere unless you use sophisticated instruments to detect it. As many hormones do, it takes fairly low concentration of this chemical to cause drastic effects on plants.
More DetailsSunday, 01/22/2017. Every day, about 1.8 million barrels of NGLs, naphtha and other ethylene plant feedstocks are "cracked" to make both ethylene and an array of petrochemical byproducts. And every day, decisions are made for each steam cracker on which feedstock—or mix of them—would provide the plant''s owner with the highest margins.
More Details· Ethylene (C 2 H 4) is an odorless, colorless gas, which acts as a plant hormone, altering the growth of many plants. Major losses caused by the ethylene can occur with many greenhouse crops including vegetables. Ethylene is a simple organic substance, which is highly active at low concentrations. Normally, as the concentration of gas increases ...
More DetailsRespiration and ethylene production is a crucial biological process in plants that characterize the ripening pattern of the fruit. With the respiration and ethylene production patterns during fruit maturity and ripening, tropical fruits are classified into two groups: climacteric and non-climacteric fruits (Table 10.2).Ethylene, a small hydrocarbon molecule, biosynthesized by all plant tissues ...
More Details· The reaction time following ethylene exposure varies with the plant material, temperature, and plant age. Ethylene is more damaging at warmer temperatures and for plants that have been stored or marketed at a mature stage. Some symptoms may appear in 1 – 2 days while other symptoms may take longer to become evident.
