Natural Gas Processing FSC 432: Petroleum Refining

A generalized natural gas flow diagram is shown in Figure 12.2 [7]. After initial scrubbing to remove particles, the first step in natural gas processing is the removal of condensate (oil) and water that is achieved by controlling the temperature and pressure of the inlet stream from the well, as shown in Figure 12.4. Gas separated in this unit is sent to acid gas recovery; the condensate or the oil recovered is usually sent to a refinery for processing

Natural Rubber Production Greenrubbertoys

In the 1830’s Charles Goodyear worked out how to vastly improve rubber beyond its natural state with a process called vulcanization, a process by which natural rubber is treated under heat and pressure to improve its elasticity and to enhance its strength and hardness. Once vulcanized, rubber becomes capable of withstanding punishing heat and pressure. Suddenly the uses of rubber opened up

Transfer molding is a natural progression in development to limit the disadvantages of compression molding. The process starts out with a blank being loaded in the chamber, which is then distributed into several cavities. In this beginning stage, pre-heating takes place in the rubber, forcing the rubber to flow through channels. This pre-heating reduces the curing time and allows the rubber to flow easier and

Natural Gas to Hydrogen (H) - processdesign

13/03/2015  The steam reforming process, after desulfurization, utilizes the natural gas feed by combining it with steam. The mixture is then passed through a reactor filled with catalysts, resulting in a mixture of carbon monoxide, carbon dioxide, and hydrogen. The subsequent water gas shift and separation units (amine plant) remove the impurity to result in highly pure hydrogen. Any wastewater produced will be sent for off-site treatment.
