Title: Method and apparatus for cooling a gaseous hydrocarbon stream
Inventor: VAN DE LISDONK CAROLUS ANTONIUS CORNELIS
IPC: F02C7/143
Filed: 2010-05-11
Abstract: A gaseous hydrocarbon stream (10) is cooled to produce a liquefied hydrocarbon stream (20). The gaseous hydro-carbon stream (10) is cooled in one or more heat exchangers (140a) using a first refrigerant from a first refrigerant circuit (100) in which said first refrigerant is compressed in a first compressor (110) driven by a first gas turbine (120) having a first inlet air stream (125) and liquefied using a second refrigerant circuit (200) wherein a second refrigerant is compressed in a second com-pressor (210) driven by a second gas turbine (220) and having a second inlet air stream (225). The cooling duty available in a stream of a chilled coolant (320) is divided over at least first (340) and second (350) parts in accordance with a common input pa-rameter, and one or both of said first and second inlet air streams (125, 225) are cooled with the chilled coolant (320), whereby the cooling duty available in the first part (340) is used to cool the first inlet air stream (125), and the cooling duty available in the second part (350) is used to cool the second inlet air stream (225).

Abstract: A bitumen and heavy oil upgrading process and system is disclosed for the synthesis of hydrocarbons, an example of which is synthetic crude oil (SCO). The process advantageously avoids the waste attributed to residuum and/or petcoke formation which has a dramatic effect on the yield of hydrocarbon material generated. The process integrates Fischer-Tropsch technology with gasification and hydrogen rich gas stream generation. The hydrogen rich gas generation is conveniently effected using singly or in combination a hydrogen source, a hydrogen rich vapour from hydroprocessing and the Fischer-Tropsch process, a steam methane reformer (SMR) and autothermal reformer (ATR) or a combination of SMR/ATR. The feedstock for upgrading is distilled and the bottoms fraction is gasified and converted in a Fischer-Tropsch reactor. A resultant hydrogen lean syngas is then exposed to the hydrogen rich gas stream to optimize the formation of, for example, the synthetic crude oil. The hydrogen lean gas stream may also be effected by a water gas shift reaction, singly or in combination or in addition with the hydrogen rich gas stream generation. Partial upgrading and the commensurate benefits is detailed as well. A system for effecting the processes is also characterized in the specification.

Abstract: A vapour compression refrigeration system includes a compressor (1) arranged to re-circulate refrigerant through a condenser (2), an expansion device (4) and an evaporator (5). To achieve rapid thermodynamically efficient defrosting of the evaporator, hot refrigerant from the condenser is stored in a defrost receiver (6) before passing through the expansion device (4). In a defrost phase, a valve arrangement (7-10) forms a closed defrost circuit connecting the evaporator (5) to the defrost receiver (6) via defrost valve (10) to allow hot fluid to pass from the defrost receiver to the evaporator and liquid refrigerant in the evaporator flows to the defrost receiver (6) via drain valve (9). In a pre-defrost phase, the valve arrangement closes the fluid input to the evaporator (5) and the compressor operates to partially evacuate the evaporator before the evaporator is connected to the defrost receiver, so that flash flooding of the evaporator with hot vapour occurs. A phase change medium (11) may be included to store heat from the condenser output and return it to the evaporator during defrost. Additional heat may be supplied to the defrost liquid to further increase the defrost speed.
