By varying the pressure of the gas in various sections of the separator, it is possible to vary the temperature, which causes the oil and some water to be condensed out of the wet gas stream. This basic pressure-temperature relationship can work in reverse as well, to extract gas from a liquid oil stream.

Pollution Prevention in the Pulp and Paper Industries

Jul 05, 2011 · Wet Oxidation: The principle of wet oxidation is that organic compound as solid or liquid form is firstly transferred to water where it contacts with an oxidant under high temperature and pressure. During wet oxidation, waste pulped with water is carbonized and its fuel value increases to the equivalent of medium-grade coal.

Jun 01, 2013 · Simplified diagrams of such cogeneration systems are proposed in Fig. 2, Fig. 3: heat from the combustion is transferred from the flue gases to the heat transfer fluid (thermal oil) in two heat exchangers, at a temperature varying between 150 and 320 °C. The heat transfer fluid is then directed to the ORC loop to evaporate the working fluid, at a temperature slightly lower than 300 °C.

Control theory - Wikipedia

To overcome the limitations of the open-loop controller, control theory introduces feedback.A closed-loop controller uses feedback to control states or outputs of a dynamical system.Its name comes from the information path in the system: process inputs (e.g., voltage applied to an electric motor) have an effect on the process outputs (e.g., speed or torque of the motor), which is measured with

Milk and dairy products: production and processing costs

However, assuming the water comes into the boiler at a temperature of 20°C, the amount of heat needed to get 1 kg of steam from 1 kg of water would be: 660 kcal - 20 kcal = 640 kcal. and the monthly steam production would be: 5.1.1.2 Water consumption. In the above example, 75 500 1 of water are needed to produce 76 500 kg of steam.
