Abstract: An olefin synthesis plant comprising: a feed pretreatment section configured to pretreat a feed stream; a pyrolysis section comprising one or more pyrolysis reactors configured to crack hydrocarbons in the feed stream in the presence of a diluent to produce a cracked gas stream; a primary fractionation and compression section configured to provide heat recovery from and quenching of the cracked gas stream; remove a component from the cracked gas stream; and compress the cracked gas stream, thus providing a compressed cracked gas stream; and/or a product separation section configured to separate a product olefin stream from the compressed cracked gas stream, wherein the olefin synthesis plant is configured such that, relative to a conventional olefin synthesis plant, more of the energy and/or the net energy required by the olefin synthesis plant and/or one or more sections thereof, is provided by a non-carbon based and/or renewable energy source and/or electricity.

Abstract: A nozzle includes: a flow path allowing gas to flow; tip opening portion(s) formed on a tip side of the flow path; a base end opening portion formed on a base end side of the flow path; and side hole(s) which is formed on the base end side from the tip opening portion and allows a part of the gas flowing through the flow path to be discharged toward the base end side. The tip opening portion(s) is formed in a direction of the flow path. The side hole(s) is formed along a circumferential direction of the flow path. When the gas is supplied from the base end opening portion, a ratio (Q1a/Q1b) of a flow rate (Q1a) of the gas discharged from the tip opening portion(s) and a flow rate (Q1b) of the gas discharged from the side hole(s) is 0.05 to 0.7.

Abstract: A method and an apparatus for reducing the corrosion of a condenser in carbide derived carbons (CDC) production where cooling/quenching of a gaseous stream metal or metalloid halide is performed by direct contact of gaseous stream with liquid cooling agent before condenser, without utilizing a heat exchanger for the temperature range above 300° C., while keeping purity of gaseous stream of metal or metalloid halide constant. The apparatus comprises a reactor for carbide to carbon conversion and a condenser for collecting the by-produced metal- or metalloid chloride, and a cooling unit comprising a tank of liquid cooling agent. Temperature of the gas stream entering the condenser is reduced by heat absorbed in vaporization of a liquid metal- or metalloid halide introduced from the tank of liquid cooling agent through by supply pump, through the supply flow valve into the gaseous stream at the exit of the reactor.

Abstract: Methods and systems for temperature-controlled, on-site generation of peracids, namely peroxycarboxylic acids and peroxycarboxylic acid forming compositions are disclosed. In particular, methods for using an adjustable biocide formulator or generator system overcome the limitations of temperature on the kinetics of the peracid generation and/or peracid decomposition inside an adjustable biocide formulator or generator system. The methods include the controlling of the temperature of at least one raw starting material, namely water, to improve upon methods of on-site generation of peracids. The methods allow for the generation of user-selected chemistry without regard to the ambient temperatures of the raw starting materials and/or the biocide formulator or generator system.
