Abstract: A B S T R A C T     The invention relates to the recovery of chlorine values from iron chloride by-produced from the chlorination of a titaniferous material containing more than 5% by weight iron oxide, and particularly from the carbo-chlorination of ilmenite, which, for example, can be the first stage in the so-called chloride route to form titanium dioxide pigment.    The iron chloride which may be ferric chloride or ferrous chloride is subjected to a combination of reduction and oxidation reactions.  In the reduction reaction, ferric chloride is dechlorinated to ferrous chloride by a reducing agent suitable for producing a chloride compound for recycle to the chlorination/process or for sale and in the oxidation reaction ferrous chloride is oxidised to ferric oxide and ferric chloride, the ferric chloride being recycled to the reduction reaction.          By this method the chlorine values are recovered from by-product iron chloride by a route which avoids the difficult reaction between ferric chloride and oxygen to produce chlorine and ferric oxide.

Title: Beam pumping unit speed control
Inventor: SKINNER DAVID R
IPC: E21B43/12
Filed: 1978-06-07
Granted: 1982-03-16
Abstract: BEAM PUMPING UNIT SPEED CONTROL This is a method and apparatus for controlling an oil-well beam pumping unit in a manner which allows increased oil production. The AC electric motor of the beam pumping unit is supplied power through a variable frequency power supply, whose frequency (and voltage) is controlled by circuitry to automatically adjust to whatever flow enters the wellbore by varying the speed of the pumping unit to maintain the speed generally proportional to the real power consumed by the pump. As the level in the wellbore can be maintained at an essentially constant minimum level, despite the relatively large hour-to-hour variations in in-flow which normally occur, the total flow from the formation into the wellbore in a given period of time is increased.
