摘要： The invention relates to a process for the production of grade AA methanol by distilling raw methanol in several distillation stages, thereby separating grade AA methanol, tail gas, and fusel oil. The methanol produced in commercial-scale synthesis plants does not correspond to grade AA. Therefore, the product must be treated in an additional distillation stage in order to reduce the methanol losses due to fusel oil. The aim of the invention can be achieved by distilling said fusel oil in an additional distillation stage at a return ratio of 5:1 or higher.

摘要： The invention concerns a method for monitoring slurry flow conditions in a non-vertical pipeline having a pipeline wall. The method comprises the steps of mounting a heater and a heat sensor externally on the wall, activating the heater to generate heat and deriving an indication of slurry flow conditions prevailing at the invert of the pipeline from the power supplied to the heater and/or from the thermal response of the heat sensor. The heater and heat sensor are mounted at the invert of the pipeline and in proximity to one another with the heater and heat sensor in thermal communication with the interior of the pipeline through the wall. In the preferred embodiment variable power is supplied to the heater such that a predetermined temperature differential is maintained between a reference temperature and a temperature sensed at the invert by the heat sensor. The required indication of slurry flow conditions prevailing at the invert is then obtained by monitoring the level of power supplied to the heater. The invention also concerns an apparatus for monitoring slurry flow conditions in a pipeline.

摘要： One aspect of the invention concerns a method of controlling a flow of slurry pumped through a non-vertical pipeline (10) by a pump (54). In the method, at least one sensor (12) is provided. This has a sensing face (42), and the sensor is mounted at a predetermined position along the length of the pipeline such that the sensing face is flush with the invert of the pipeline at that position. The sensor is calibrated to provide output signals related to the velocity of the slurry at the invert. The operation of the pump and/or the density of the slurry are then controlled in response to the output signals from the sensor. Other aspects of the invention relate to the apparatus and to a slurry pipeline control system incorporating the apparatus and in which the method is implemented.
