APPARATUS FOR PRODUCING PLASTIC LUBRICANTS Russian patent published in 1997 - IPC

FIELD: chemical engineering; production of lubricants. SUBSTANCE: proposed apparatus comprises plurality of vessels for oil and precursor reactive components, vessels being connected via supply pipes with reactor. Each supply pipe carries proportioning device, while reactor is communicated with evaporator having heating jacket and circulation circuit, along which product to be dewatered circulates. Reactor is also communicated with cooler connected with vessel for oil and with vessel with dopes through supply pipes having proportioning devices. Apparatus further comprises two docking-distributing throttling devices, one of which serves to connect reactor outlet with evaporator inlet, while second device is intended to connect evaporator outlet with cooler inlet. Reactor and cooler are made, each of them, in form of multi-section mixer, each section of which is formed as self-sustained unit with individual heat supply or heat removal. EFFECT: invention offers numerous advantages: multi-purpose unit for continuous production of wide range of high-quality plastic lubricants can be designed on its basis; intensified production process; flexible process control. 7 cl, 2 dwg
