Crushed sugar cane cellulose process - uses steam as a heat exchanger to bring it to a fluid for pumping without an explosion hazard

Process is for transfer of high viscose spent lyes, partic. spent lyes from alkaline hydrolised crushed sugar cane, where the temp. is raised to bring it to a condition for pumping. The lye is heated by a heat exchange circuit, and directly heated by heat exchange before it enters the recirculating...

More Information
Summary:Process is for transfer of high viscose spent lyes, partic. spent lyes from alkaline hydrolised crushed sugar cane, where the temp. is raised to bring it to a condition for pumping. The lye is heated by a heat exchange circuit, and directly heated by heat exchange before it enters the recirculating pumps. Process ensures that the material can be transported by a pump, the thickness being reduced sufficiently, without the risk of an explosion.
