Disolve the salt in the water in a large bowl, place the pork chops in the mixture, cover and refrigerate for 20 minutes.
Remove the pork chops from the mixture and pat dry with paper towels.
Heat the olive oil in a large skillet over medium heat. Place the chops into the heated oil and cook about 5-7 minutes per side, depending on how thick the chops are. Transfer the pork chops to a plate.
Reduce the heat to medium low. In the same pan add the butter, prunes, water, pinch of salt and sugar. Cook for about 15 to 20 minutes, stirring occasionally with a wooden spoon. Add the wine and salt and continue cooking for 15 minutes more. Pour half of the sauce over the chops and serve immediately, using the remaining sauce as table gravy.
