Patent CA-2301177-A1 (CA)
Inventor: BERGLUND KRIS A
IPC: C12P/
Filed: 1998-08-18
Abstract: A highly efficient process for the production and recovery of pure succinic acid from a succinate salt that involves minimal use of additional reagents, and produces virtually no waste by-products, and permits internal recycle of the base and acid values, is provided. The method involves the formation of diammonium succinate, either by using an ammonium ion based material to maintain neutral 8 pH in the fermenter or by substituting the ammonium cation for the cation of the succinate salt created in the fermenter. The diammonium succinate can then be reacted with a sulfate ion, such as by combining the diammonium succinate with ammonium bisulfate and/or sulfuric acid at sufficiently low pH to yield succinic acid and ammonium sulfate. The ammonium sulfate is advantageously cracked thermally into ammonia and ammonium bisulfate. The succinic acid can be purified with a methanol dissolution step. Various filtration, reflux and reutilization steps can also be employed.

Abstract: A die post assembly that supports a metal panel in a position to allow an implement such as a roller or die steel to flange, pre-hem or hem an edge of the panel. A die post support surface is disposed on a panel support element and an edge member of the assembly. The die post support surface is shaped to support the panel and includes a bearing surface that supports an overlying portion of the panel against deformation as the marginal edge portion of the panel is bent in a flanging or hemming operation.
