摘要： This invention is related to an apparatus which incorporates a microfabricated silicon mass flow sensor to measure city gas flow rate in a medium pressure range for utility industry which is dominated by conventional mechanical meters such as turbine and rotary meters. The microfabricated mass flow sensor is so called micro-electro-mechanical systems (a.k.a. MEMS) device. Due to the small feature size of micro scale for MEMS mass flow sensor, the invented apparatus includes many advantages such as low power consumption, compact package, high reliability and extended dynamic measurement range. This apparatus is also provided with a stable flow conditioning to achieve a desired dynamic range capability. Furthermore, because of the high accuracy characteristic, the apparatus in this invention could be applied for custody transfer or tariff in utility industry as well.

摘要： An all-electronic utility gas meter using with micromachined (a.k.a. MEMS Micro Electro Mechanical Systems) silicon sensor to measure gas metrology data for custody transfer or tariff in city gas metering application is disclosed in the present invention. The meter has two separate metrology units. One of the units is located in the main flow channel with the insertion probing configuration while the other is configured as a bypass unit assembly with the main metrology unit. The bypass metrology unit can perform independent metrology tasks and can be exchanged onsite during service, maintenance or repair without dismantle the meter from the service pipeline. The bypass metrology unit also can be used to compare the measured data from time to time and performance self-diagnosis that shall help the performance and data authentication during the meter field service. Both of the units can be powered by battery or external sources. The units can be connected to network as well as provide internal plural storages for data transmission and safety.

摘要： A joint process for preparing alcohol/ether mixtures, alcohol/hydrocarbon mixtures and synthesizing ammonia is disclosed. In particular, a process of converting CO and CO2 present in the feed gas of ammonia synthesis, comprising H2 and N2 as major components, into useful co-products is disclosed. The process is characterized in that the alcohol/ether forming reaction is firstly carried out by using a copper series catalyst, then the alcohol/hydrocarbon forming reaction is carried out by using an iron series catalyst, the individually formed alcohol/ether and alcohol/hydrocarbon products are separated by water cooling and condensing, and discharged into corresponding storage tanks, and the remaining gas, in which the amount of CO and CO2 is less than or equal to 10 ppm, is fed into the ammonia synthesis system. Since the alcohol/hydrocarbon can be used as liquid fuel, the product composition of the ammonia plant is improved, and the amount of CH4 fed into the ammonia synthesis system is decreased, and the amount of venting is thus reduced.
摘要翻译：公开了制备醇/醚混合物，醇/烃混合物和合成氨的联合方法。特别地，将氨合成的原料气体中存在的CO和CO 2 CO 2转化为主要组分的方法，包括H 2 N 2和N 2 N 2 ，成为有用的共同产品。该方法的特征在于首先通过使用铜系催化剂进行醇/醚形成反应，然后通过使用铁系催化剂，单独形成的醇/醚和醇/烃来进行醇/烃形成反应产物通过水冷和冷凝分离，并排放到相应的储罐中，CO和CO 2 CO 2的量小于或等于10ppm的剩余气体进料到氨合成系统。由于醇/碳氢化合物可以作为液体燃料，所以氨厂的产品组成得到改善，并且进入氨合成系统的CH 4 N 3的量减少，排气量为从而减少。

摘要： An intelligent approach for performing administrative functions generally involves performing a set of administrative function steps within a “maintenance window” that is defined by one or more specified time periods. First, a set of administrative function steps to be performed are identified. The set of administrative function steps is prioritized to produce a set of prioritized administrative function steps. Then, the set of prioritized administrative function steps is performed during the maintenance window. Aspects and features of the invention include: identifying and prioritizing administrative function steps; estimated function times and maintenance window; failure prediction; environment recommendations; history information and learning techniques; saving state and context information; and user feedback.
