What Is an Unsaturated Resin Reactor: UPR Process, Design and Applications Answering the core question: What is an unsaturated resin reactor? An unsaturated resin reactor is a heated, agitated vessel, normally 316L stainless steel and fitted with a fractionating column and a condenser, in which unsaturated polyester resin is produced in two distinct stages. First, polycondensation: a dibasic acid blend of maleic anhydride and phthalic anhydride or isophthalic acid is reacted

Why Chemical Reactors Are Key To Industrial Manufacturing Why are chemical reactors key to industrial manufacturing? A chemical reactor is the one piece of equipment where raw material is actually turned into product, so it is where value is created rather than merely moved or stored. It performs the conversion that defines the product, and it does so at conversion of 60 to 99.9 percent and selectivity of 80 to 99.5 percent while holding a reaction that may release up to 300

What Is The Difference Between A Pressure Vessel And A Storage Tank: Code, Design and Inspection What is the difference between a pressure vessel and a storage tank? The dividing line is pressure. A pressure vessel is built to hold a gas or liquid at a pressure different from, and usually well above, atmospheric, and it is designed, fabricated and inspected to a pressure-equipment code such as ASME BPVC Section VIII with a stamped nameplate stating its maximum allowable

What Is A Separator In The Oilfield: Function, Types and Process Role What is a separator in the oilfield? An oilfield separator is a pressure vessel installed near the wellhead or at a gathering station that splits the raw well fluid, a mixture of crude oil, natural gas and produced water, into its separate phases by gravity settling, so each can be measured, treated and routed correctly. The two main classes are the two-phase separator, which divides gas from liquid, and

Waste Conversion Reactor: Pyrolysis, Gasification and Hydrothermal Pathways What is a waste conversion reactor? A waste conversion reactor is a vessel that transforms low-value or hazardous refuse, biomass, plastic or sludge into energy or chemicals, and it is defined by which of four pathways it uses: pyrolysis, heating in the absence of oxygen at 400-700°C to yield pyrolysis oil, gas and char; gasification at 700-1200°C to make syngas of 10-30 MJ per normal cubic metre;

Industrial Waste Treatment Reactor: Processes, Materials and Corrosion Control What is an industrial waste treatment reactor? An industrial waste treatment reactor is a vessel in which hazardous or polluted waste, usually liquid, is chemically, biologically or physically transformed into a safer, separable form before discharge or disposal, and it is defined less by a single reaction than by the variety of duties it must survive. The four common chemistries are neutralisation

How To Choose The Right Industrial Pressure Vessel Manufacturer: A Procurement Checklist How do you choose the right industrial pressure vessel manufacturer? You qualify a manufacturer on five gates, in order: valid design and fabrication certification (an ASME U-stamp with National Board registration, or PED 2014/68/EU for Europe), demonstrated code capability for your duty (design pressure 0.1-10 MPa, design temperature -20 to 350°C, the correct material and corrosion

How Do I Choose The Right Material For A Pressure Vessel: A Selection Guide How do I choose the right material for a pressure vessel? You select the material from the service conditions, in this order: what the medium is and how corrosive it is, the design temperature, the chloride and pH level, whether the duty is abrasive, and the applicable code and cost target. The typical mapping is carbon steel for dry, clean, non-corrosive service; 304 or 316L stainless steel where

Agitation Reactor: Impeller Types, Mixing Regimes and Heat Transfer Design Answering the core question: What is an agitation reactor? An agitation reactor is a vessel in which a mechanically driven impeller, mounted on a central shaft, mixes the contents to achieve blending, heat transfer, gas dispersion or solids suspension during a reaction, rather than relying on the flow from pumps or the reaction itself. The agitator, not the shell, is the heart of the machine, and its

What Is the Best Method of Separation for Oil and Water: A Selection Guide Answering the core question: What is the best method of separation for oil and water? There is no single best method; the right one is set by the droplet size of the oil in the water, and everything else follows from that. Free oil, droplets above 150 micrometres, separates by gravity alone in an API 421 separator, reaching 50-150 mg/L. Dispersed oil of 20-150 micrometres needs a plate pack interceptor

What Is a Gas Coalescing Separator: Mechanism, Design and Applications Answering the core question: What is a gas coalescing separator? A gas coalescing separator is a two-stage vessel that removes very fine liquid aerosol from gas by first merging the tiny droplets into larger ones and then separating the enlarged droplets by gravity or by a vane pack. In the first stage, gas passes through a bed of fine fibrous coalescing elements where droplets from 0.1 to 1 micrometre are

What Is an Acrylic Reactor: Polymerization Chemistry, Design and Control Answering the core question: What is an acrylic reactor? An acrylic reactor is a stirred vessel in which acrylic and methacrylic monomers such as acrylic acid, butyl acrylate, methyl methacrylate and styrene are polymerised by a free radical mechanism into acrylic resins, emulsions or elastomers. The reaction is strongly exothermic, releasing 60-80 kJ per mole of monomer, which is roughly 700-1,100 kJ
