A method and system are disclosed for pushing credit payments as buyer initiated transactions. The buyer communicates payment instructions to initiate payment of accounts payable items so that the existing credit card infrastructure can be used to make payments to merchants without a credit card transaction being initiated by the merchants. In this way, a buyer can push credit payments into the system without having to communicate with the merchant, and these transactions can be processed as credit transactions with respect to standard settlement procedures, for example, as used by credit card receipt acquirers. This ability to push credit payments provides an advantageous, efficient and powerful solution to handling accounts payable operations, particularly in a corporate environment. And a purchasing management system can be used to manage and control these activities and to allow selection, or automatic selection based upon merchant profiles, of whether to make payments as pushed credit payments or cash/debit transactions.

The invention discloses a pressurizing solution deep dehumidifying device and a pressurizing solution deep dehumidifying method. In the pressurizing solution deep dehumidifying device, air and a strong solution are pressurized to a certain high-pressure state and then conveyed into a dehumidifier so as to be dehumidified, the dehumidified air and a weak solution are throttled to a normal-pressure state by a throttle valve, thus providing dry air with very low humidity, so as to dry spaces or objects which need to be dried. A throttled weak solution flowing out from the dehumidifier is conveyed into a normal-pressure regenerator through a solution pump for regeneration, and then is recycled while achieving a certain concentration. Because the pressurized air has higher water vapor partial pressure than the air under normal pressure, thus increasing the difference of the water vapor partial pressure between the air and a solution surface, and further enhancing the dehumidifying process; after contacting with a dehumidifying solution, the air can also reach the water vapor partial pressure approximate to the solution surface, after dehumidified high-pressure air is throttled to normal-pressure air, the lower water vapor partial pressure is got, and therefore deep dehumidified and dried air with lower moisture content can be obtained.
