Abstract: Provided herein are techniques for rescuing a commercial transaction identified as suspect, possibly based on suspicion of fraud or due to the risk associated with the commercial transaction. Various implementations include systems and methods that can rescue a purchase transaction involving a purchasing party (hereafter, a “purchaser”) and a selling party (hereafter, a merchant”). The item or items being purchased in the purchase transaction can include goods, a services, or property interests (e.g., real, intellectual, or otherwise). Particular implementations can facilitate the rescuing of a purchase transaction that has been declined, canceled or suspended (e.g., pending further review) by an involved party (e.g., the selling party) based on that party's concern (e.g., fraud or high risk) with respect to the purchase transaction.

Abstract: A technique for improving collaboration between relevant parties in a commercial transaction involves sending a timely alert including descriptors useful for reducing the number of do-not-recognize (DNR) transactions. A system constructed in accordance with techniques described in this paper can integrate multiple stakeholders and service providers. The system can facilitate alerting stakeholders of a presumably fraudulent transaction and/or enabling stakeholders to alert other stakeholders, while reducing DNR resource costs.

Abstract: The regeneration of HF alkylation acid in an alkylation unit is improved by withdrawing a vapor stream from the HF regenerator tower and condensing the stream to form a liquid fraction which is accumulated in a side distillation zone; the collected liquid fraction, comprising HF acid, water and some stripping medium is distilled in a batch or continuous type operation to drive off the HF acid (along with stripping medium) and the vapor is returned to the regenerator-stripper vessel. The distillation of the sidedraw liquid is continued until the composition of the liquid attains the azeotropic value or as near to that value as desired. The azeotrope, comprising water and acid can then be dropped out of the distillation vessel for disposal by neutralization in the conventional way.
