it developed acid treatment equipment as the purpose
to reduce the acid value of the solvent (ethyl acetate)
which was recovered at the recovery equipment
|
|
|
It reduces an acid value in treatment agent’s absorbing
acetic acid in the ethyl acetate and removing a settled
treatment agent.

It is result of adding acetic acid and water to
solution of 100% of ethyl acetates ,investing a treatment
agent in 200ml of solution of acid value 4.94, 1% of
moisture and measuring an acid value after stirring
for 5 minutes

It is the result of the bringing in test in printing
company which took cooperation.
It processed the recovery liquid of about 3 acid
values and it confirmed reduction to equal to or less
than 0.05 acid values and we received report that was
not a problem as a result of the reuse with the dry
laminating-machine .
Also ,there was an effect that the degree of moisture
after processing gets for about 25% to be low since
before processing ,too.

●It manufactures according to the request the customer.
●It is possible to examine by the processing experiment
or the test machine bringing in
the company,if it is possible to take your recovery
liquid sample too.
●The development test of the diversion into the
other solvent and the water-treatment agent too,is in
progress.
●Only the necessary quantity can be processed.
●It is possible for the acid value to reduce in
few various cost.
●The maintenance ,too,is easy in the simple operation.

In organic solvent recovery
,it links up with Environmental Partnership corporation
and it tackles the recycling processing of a industrial
waste.
