Claim 18:
19. A controller to control electrical power generated in an organic fluid processing heat operation in the vicinity of a drilling rig during drilling operations, the controller comprising:
an input in signal communication with a drilling fluid return pipe sensor to provide a temperature of a drilling fluid entering a drilling fluid return pipe and flowing from the drilling fluid return pipe to a drill string and to a drill bit connected to the drill string, the drill bit positioned to rotate based on one or more of rotation of the drill string and flow of the drilling fluid; and
a set of inputs/outputs in signal communication with a heat exchanger valve and a working fluid flow control device, the controller configured to:
in response to the drilling fluid being within an operating range, transmit one or more signals (a) to adjust a position of the heat exchanger valve, thereby to divert drilling fluid to a heat exchanger, the heat exchanger to facilitate transfer of heat from the drilling fluid to a working fluid flow, thereby to cause an organic fluid processing heat unit to generate electricity or (b) to adjust the working fluid flow control device, thereby to control an amount of heat transferred to the working fluid flow.
