Certain embodiments of the invention may be found in a method and system for transmission control protocol (TCP) large receive offload. A coalescer may be utilized to collect TCP segments in a network interface card (NIC) without transferring state information to a host system.

When the CLT is full, the coalescer may close a current entry and assign the network connection to the available entry. The coalescer may also update information in the CLT. When an event occurs that terminates the collection of TCP segments, the coalescer may generate a single coalesced TCP segment based on the collected TCP segments. The coalesced TCP segment and state information may be communicated to the host system for processing.

The invention discloses a novel high-efficiency crude oil electric dehydration and desalination method and novel high-efficiency crude oil electric dehydration and desalination equipment, which can be used for dehydrating and desalinating crude oil emulsion in oil refineries. The processing equipment mainly comprises an inlet component, a tank and an electrostatic precoalescer; when a high-voltage explosion-proof transformer outside the device applies high-voltage alternating current to the crude oil emulsion in a corrugated hollow tube through metal electrode plates by a high-voltage insulating wire, a non-uniform alternating current field is produced between the electrode plates to cause dielectrophoresis coalescence of dispersed phase water particles; the flow state of the crude oil emulsion in the hollow tube is turbulent flow, and the turbulent flow increases the collision probability of the dispersed phase water particles in the crude oil emulsion and obviously shortens hydraulic retention time; and a flowing passage in the electrostatic precoalescer can be designed to be corrugated circular or wavelike quasi-rectangular. By using the method and the equipment, the dispersed phase water particles subjected to electrostatic precoalescence can obviously reduce subsequent gravity settling time and improve the processing efficiency; and after the crude oil emulsion enters the tank from the inlet component at the left end, the crude oil emulsion flows along the horizontal direction and can reduce the power consumption of an inlet.

A method of drying liquid and gaseous hydrocarbons by contacting a feed stream of the hydrocarbon with an aqueous solution of a salt drying agent prior to passing the stream through a salt dryer to remove part of the water in the stream. The aqueous solution of the salt drying agent is generated in the salt dryer when the partly dried stream comes into contact with the drying salt and forms the solution. The solution is circulated in a loop from the salt dryer to the incoming feed and then through a liquid / liquid coalescer which removes a portion of the water together with dissolved salt from the mixture before the mixture is passed on to the salt dryer where further removal of water occurs. The salt dryer is off-loaded by a substantial factor by the initial partial dehydration and does not require to remove such a large amount of water; the salt consumption is therefore reduced in proportion to the amount of water removed in the treatment steps which precede the dryer.
