Abstract: The invention relates to a piston system (1) for use in a homogenizer, comprising a piston (2) that is configured and arranged to make a reciprocating movement in use of the piston system, a cylinder (3) that is configured and arranged to receive and guide at least a first part of the piston, a first supply channel (8) that is configured and arranged to supply a lubricating medium (9) to a portion (10) of the first part of the piston that in use is arranged inside the cylinder, and a second supply channel (13) that is configured and arranged to, in use, supply a cooling medium (14) to a second part of the piston outside the cylinder. Also disclosed is a process for the production of an elastomer agglomerate composition forcing a slurry comprising elastomeric particles through an aperture to obtain the elastomer agglomerate composition using the piston system.

Abstract: A process for the production of an elastomer agglomerate composition wherein the process comprises the steps in this order: (a) providing a slurry comprising elastomeric particles having an average particle size of ≤150 nm in water; and (b) forcing the slurry from (a) through an aperture at a flow velocity of at least 500 m/s. The elastomer agglomerate compositions produced via such process demonstrate a particularly desirable high average particle size.

Abstract: The present invention relates to a process for the production of a polymer using a compound comprising at least 2 unsaturated carbon-carbon bonds, wherein the process comprises a polymerisation section and a purification section, wherein the product from the polymerisation section is subjected in the purification section to a sequence of purification steps comprising: ⋅removal of the vapour phase from the product from the polymerisation section by means of flash separation to obtain a first vapour phase and a polymerisation product; ⋅subjecting the first vapour phase to a compression and condensation treatment to obtain a second vapour phase and a condensed monomer phase; wherein the purification steps are conducted in this order. Such process allows for the optimal utilisation of raw materials in the polymerisation process.

Abstract: In an embodiment, a method of recovering acetone comprises separating a bisphenol A stream into a bisphenol A product stream and an extraction stream comprising unreacted acetone; recovering the unreacted acetone in a recovery section of the bisphenol A production facility and forming a bisphenol A plant acetone recovery stream comprising methanol and a recovered acetone; introducing the bisphenol A plant acetone recovery stream to a phenol purification plant; and purifying the bisphenol A plant acetone recovery stream in the phenol purification plant to form an acetone product stream. The acetone product stream can comprise a reduced amount of methanol as compared to the bisphenol A plant acetone recovery stream.
