Title:
PROCESS AND EQUIPMENT FOR CHARGING ETHYLENE CARBONATE CONTAINING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2007/055207
Kind Code:
A1
Abstract:
The invention aims at providing a process for stably charging a high-quality
ethylene carbonate containing material by determining the number of particles
contained in the material which particles are solid at atmospheric temperature
in handling (e.g., at ordinary temperatures) with high reproducibility easily
and accurately; and equipment for charging the material. The process comprises
passing an ethylene carbonate containing material from a material storage vessel
through a charging pipe and then through a pipe for measuring particles, which
pipe is a branch separated from the charging pipe at a midway point and is heated,
continuously in line, determining the number of particles contained in the material
with a particle measuring instrument connected to the pipe for measuring particles,
and charging the material into a storage vessel through an outlet of the charging
pipe when the number of particles of 0.2μm or larger has reached a level
below the reference value.
