Butyl and Halobutyl-Rubber (IIR/HIIR)

TECHNOLOGY FOR THE PRODUCTION OF BUTYL AND HALOBUTYL-RUBBER (IIR/HIIR)

Butyl Rubber (IIR) is an elastomeric copolymer of Isobutylene and Isoprene, generally offered in a wide variety of polymer grades.

Halobutyl-Rubber (HIIR), such as Bromobutyl (BIIR) or Chlorobutyl (CIIR) rubbers, is obtained through the halogenation of the isoprene groups of the IIR, producing a rubber with improved properties and characteristics. HIIR presents higher curing rates and can easily co-vulcanize in elastomer blends with other rubbers, such as NR (Natural Rubber), BR (Butadiene Rubber) and SBR (Styrene-Butadiene Rubber).

The IIR and HIIR rubbers, thanks to their high gas and liquids impermeability, excellent mechanical properties preserved in a wide range of temperature, good resistance to fatigue, and an elevated resilience to most chemicals, find a large spectrum of applications. The major use is in the tyre industry (tyre curing bladders, inner liners, tubeless tyres…), and other applications include: adhesives, protective clothing, sealants, pharmaceutical stoppers, fuel additives, vibration damping devices.

CONSER technology for the production of IIR and HIIR, developed with the support of consultants and specialists having long experience in the synthesis of butyl rubber, is characterized by the highest product quality and by reduced consumption of raw materials, chemicals and utilities.

Thanks to the operating experience in industrial IIR/HIIR plants, as well as the intensive research by CONSER engineers and specialists, CONSER is now in position to offer two different technologies for the halogenated rubber production: the Double Slurry System (DSS) and the new technology Polymer Direct Dissolution (PDD), which is based on the Solvent Replacement Process (SRP).

The PDD technology, by eliminating the slurry water step, represents a simplificaition of the overall process of manufacturing Halobutyl Rubber. Its several advantages include: easier product quality control and thus stable rubber quality; reduced investment cost; simplification of process and operation.

Maleic Anhydride (MAN)

TECHNOLOGY FOR THE PRODUCTION OF MALEIC ANHYDRIDE (MAN)

Maleic anhydride (MAN) is a highly reactive colourless solid widely used in the petrochemical industries for Unsaturated Polyester Resins (UPR), fibreglass enriched resins, 1,4 Butanediol (BDO), lubricating oil additives, artificial sweeteners, flavour enhancements.

MAN market is in continuous expansion, presenting solid and constant growth over the last 30 years due to its inherent application flexibility and supply constraints, exacerbated by a number of plant outages and higher consumption as consumers rebuilt inventories.

CONSER, with over 30 years of experience in the Maleic Anhydride production, is able to deliver an extremely efficient process design, guaranteeing the highest standard of product quality, while reducing the operating and capital costs investment needed. Thanks to an advanced reaction system integrated with a patented process of recovery and purification, CONSER technology is highly advanced compared to the other commercial technologies available.

Epichlorohydrin Eco-Friendly (ECH-EF)

TECHNOLOGY FOR THE PRODUCTION OF EPICHLOROHYDRIN ECO-FRIENDLY (ECH-EF)

Epichlorohydrin is a C₃ organic epoxy compound, which combines the reactivity of an epoxy group (an oxygen bridge) with the additional reactivity of a chloro-group.

Epichlorohydrin undergoes a great variety of chemical reactions with many types of compounds. It is the major raw material for epoxy resins, which account for up to 75% of total output.                                                         Thanks to its inherent versatility, it is used in a wide variety of other applications, including ion exchange resins, textiles, paper sizing, special inks and dyes, surface active agents, elastomers, plasticizers, agricultural products, liners, pharmaceuticals and many other applications.

CONSER, besides having secured in the past decades (over 40 years of experience) a leading position as licensor of the conventional epichlorohydrin process (ECH) from propylene and chlorine, has recently developed and patented a new technology route, called ECH-EF (Epichlorohydrin Eco-Friendly), to produce epichlorohydrin using glycerin and hydrogen chloride as raw materials.

The new ECH-EF technology is the most effective route to produce epichlorohydrin, thanks to its several advantages: lower cost of the raw materials; lower plant investment cost; substantial reduction of energy consumption and of the aqueous and chlorinated by-products.

Epichlorohydrin (ECH)

TECHNOLOGY FOR THE PRODUCTION OF EPICHLOROHYDRIN (ECH)

Epichlorohydrin (ECH) is a C₃ organic epoxy compound, which combines the reactivity of an epoxy group (an oxygen bridge) with the additional reactivity of a chloro group.

Epichlorohydrin is one of the most important building blocks of the petrochemical panorama, with its major application for the epoxy resin production accounting for over 75% of the total market.                                                Thanks to its inherent versatility, it is used in a wide variety of other applications, including ion exchange resins, textiles, paper sizing, special inks and dyes, surface active agents, elastomers, plasticizers, agricultural products, liners, pharmaceuticals and many other applications.

Conser, with over 40 years of experience in the Epichlorohydrin production, is able to offer a technologically advanced process, combining several advantages: from the minimization of waste product and utilities consumptions to the highest standards of quality of the product.

CONSER is able to provide the technical design also for the emerging Epichlorohydrin route from Glycerol and Hydrogen Chloride, called Epichlorohydrin Eco-Friendly (ECH-EF). For additional information on the latter, see ‘Epichlorohydrin Eco-Friendly’ page.
