AbstractDeaerator is normally used in Chemical Industries, Process Industries, Power Plants and in Paper and Pulp Industries. The oxygen in the boiler feed water is the main reason of boiler corrosion. Oxygen corrosion is one of the biggest dangers of boiler. The function of the deaerator is to remove the dissolved oxygen from the boiler feed water before entering into boiler .The removal of di...

Thermal-energy storage systems consisting of multiple tanks allow the implementation thermocline-control methods, which can reduce drop in outflow temperature during discharging and increase volumetric density utilization factor. Multi-tank based on extraction mixing methods were assessed using simulations assuming fluvial rocks as material compressed air heat-transfer fluid. For adiabatic cond...

We discuss a tank design problem for a multi product plant, in which the optimal cycle time and the optimal campaign size are unknown. A mixedinteger nonlinear programming (MINLP) formulation is presented, where non-convexities are due to the tank investment cost, storage cost, campaign setup cost and variable production rates. The objective of the optimization model is to minimize the sum of t...

A benchmark for the test of control scenarios of sequencing batch reactors (SBR) used for wastewater treatment is proposed. The plant layout includes a buffer tank for wastewater storage in front of the SBR. Performance criteria based mainly on the quality of the effluent are given. The use of the benchmark is illustrated by the study of the effects on the effluent of the control of dissolved o...

The Neptune system is a mobile robot system used to remotely inspect above-ground storage tanks (ASTs) while immersed in the petroleum product, in order to ascertain from the inside-out the state of corrosion of the floor and side-walls using video and ultrasonics, according to the guidelines laid out by the American Petroleum Institute (API). The robot system allows unmanned entry and sensor d...
