Economic Design and Operation of Process Heat Exchange Equipment

Introduction A thorough investigation of all equipment in a sugar factory covered by this title would result in a monumental publication. This relatively modest paper purports to draw attention to a few specific aspects of economy in juice heating. Considering the abundance of comprehensive articles on liquid-vapour and liquidliquid heat exchangers appearing in chemical engineering journals it ...

Safe Design and Operation of Tank Reactors for Multiple Reactions: Uniqueness and Multiplicity

A method is developed to design a tank reactor for unique operation and for two simultaneous or consecutive reactions of the first order. Dimensionless groups are introduced which are either exclusively representative for the properties of the reaction system or exclusively for the design and operating variables. In a plot of the dimensionless slopes of the heat withdrawal line versus the dimen...

the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...

Design, Development and Analysis of Toggle Lever Caliper Cable Trolley Brake for Fail Safe Operation

Present cable trolley brakes used in material transfer or overhead trolley transport systems uses twin shoe caliper brakes operated by solenoid. These brakes are not fail safe, means that slip occurs between cable and brake caliper. Sometimes overloading leads to wear of brake shoe material. The failure of brake system may increase the chances to loss of life of occupant. These conventional cal...
