Ethylene data analytics is challenging 1. Ethylene plants have incredible heat differentials and this creates challenges: Heat Integration is a must: • Variables across the plants are inter-related to each other • Effect of one variable is felt across 100’s of inter-related variables across the plant. Good operation of an Ethylene plant is finding the sweet spot of pushing

Read MoreEthylene (CH 2 = CH 2) is an unsaturated hydrocarbon gas acting naturally as a plant hormone. It acts at trace levels throughout the life of the plant by stimulating or regulating the ripening of fruit, the opening of flowers, the abscission (or shedding) of leaves and, in aquatic and semi-aquatic species, promoting the 'escape' from submergence by means of rapid elongation of stems or leaves.
Read MoreEthylene is a group of plant growth regulators which are widely used for ripening fruits and for the production of more flowers and fruits. Ethylene is a small hydrocarbon, the colourless flammable gas which is denoted by a formula C 2 H 4 or H 2 C=CH 2. Ethene is the IUPAC name for ethylene. It has a “sweet and musky” odour when it is pure.
