    摘要: Methods and systems for removing drilling fluid from wet drill cuttings are described. According to some embodiments, the method comprises: at a pressure above atmospheric pressure: using an internal combustion engine, combusting an air-fuel mixture comprising air and a hydrocarbon-based fuel, thereby producing a combustion exhaust at a first temperature; providing the combustion exhaust to the wet drill cuttings to contact and directly heat the wet drill cuttings by convection so that at least some fluid is evaporated therefrom and at least some dry solid drill cuttings remain, the evaporated fluid comprising drilling fluid and water; condensing at least a portion of the evaporated fluid to produce condensed drilling fluid, water and non-condensable inert gas; and separately recovering the condensed drilling fluid, the water and the dry solid drill cuttings.

    摘要: A concentration control device enables concentration control at high speed and with suppressed overshoot and is used in a raw material vaporization system that introduces a carrier gas into a liquid or solid raw material contained in a vaporization tank, vaporizes the carrier gas, and supplies a raw material gas generated by vaporization. The concentration control device includes flow rate control equipment that controls a flow rate of the carrier gas, a concentration measurement unit that measures a concentration of the raw material gas, and a flow rate control unit that controls a flow rate operation amount input to the flow rate control equipment by model predictive control based on a target concentration value of the raw material gas and a measured concentration value of the concentration measurement unit.

    摘要: Methods and Apparatus for Rejecting Moisture from a Desiccant Solution A method of rejecting moisture from a working desiccant solution and regenerating the working desiccant solution comprises receiving a stream of desiccant solution containing moisture to be rejected (12), and diluting at least a portion of the stream of desiccant solution containing moisture to be rejected, to form a diluted stream (38). The method further comprises passing the diluted stream (38) through an evaporator (24) for evaporating the moisture from the diluted stream; concentrating the desiccant solution, thereby to regenerate the desiccant solution; and outputting a regenerated stream of desiccant solution (14).

    摘要: Disclosed is a process for operating a flashline heater and a flashline separation system. In the process and system, heat is supplied to the flashline heater by a first steam stage followed by a second steam stage. The steam pressure is controlled by a steam control system such that the pressure in the first steam stage is not equal to the pressure in the second steam stage. Also disclosed is a process for retrofitting a steam control system in a flashline separation system of an olefin polymerization system at least by changing the number of steam stages in the flashline separation system to include a first steam stage followed by a second steam stage, and changing the stream pressure control scheme such that the pressure in the first steam stage is independently controlled to be not equal to the pressure in the second steam stage.
