Some preferred versions of this process are:
-The Roselius Process Invented by Ludwig Roselius and Karl Wimmer, this was the initial commercial decaffeination process. It involved steaming the beans with salt water after which bathing the beans in benzene. This method has develop into unpopular due the health issues associated to benzene.

-The Direct Method This method needs the beans to become steamed for any half hour followed by repeated rinsing with dichloromethane or ethyl acetate. The rinsing step repeats for about ten hours.
-The Indirect Method (also called water processed) Initially the beans are soaked in hot water until the water is essentially brewed coffee. At this point the beans are removed and also the chemicals dichloromethane or ethyl acetate are added and used to decaffeinate the water. This decaf coffee water is added having a fresh batch of beans, along with the process is repeated. Immediately after some cycles the water is so full of coffee that the only chemical left to take is definitely the caffeine, and so none of the bean's strength or flavor is lost.
-The CO2 process Well known as a result of fact that no harmful chemicals are used. This method uses liquid carbon dioxide to dissolve the caffeine at high pressure. Beans are initial steamed, then soaked by supercrital carbon dioxide at a pressure of roughly 200 atmospheres. Soon after ten hours the CO2 is evaporated with the Caffeine. The CO2 is then recycled to work with with another batch.
-The Triglyceride Process This process requires soaking the beans in hot water to draw the caffeine towards the surface of the bean. Then the hot beans are covered in particular coffee oils. The oils are produced from old coffee grounds, and at high temperatures the Triglycerides found inside the oils eliminate the caffeine inside the beans.
