  1. What's new in this club
  2. Dear Members, we will share quiz links, questions, and discussion topics directly with whatsapp group. Please join only 1 group as - all groups will receive same posts Only for Chemical Engineers They will be admin only groups ... you will not be allowed to post - Marketing people should not join these groups. All interaction will take place via websites Chemical Engineering Group 1 https://chat.whatsapp.com/JUY6HxtvBTr2MziQt7uqP3 Chemical Engineering Group 2 https://chat.whatsapp.com/Fut7WlEHutvHbAjhKaYePO Chemical Engineering Group 3 https://chat.whatsapp.com/EB1caADntoFDchLt7WrHpA Chemical Engineering Group 4 https://chat.whatsapp.com/E8lZmGcRQLvLmDK1dj3zZA Chemical Engineering Group 5 https://chat.whatsapp.com/F9PwkSn2suXCzc9nCirrJs Chemical Engineering Group 6 https://chat.whatsapp.com/Lo2qYgDryYQBVzDGhbuBlP Chemical Engineering Group 7 https://chat.whatsapp.com/LqaC3SJNrEtEI1XrtnW7dh Chemical Engineering Group 8 https://chat.whatsapp.com/KCDnqWvwe8b6qeIld6HMpT Chemical Engineering Group 9 https://chat.whatsapp.com/Ga2SQkO3qAm3BeqMR15jvt Chemical Engineering Group 10 https://chat.whatsapp.com/L8jyVROIgzfA0uVYFocBoW

    A proportional–integral–derivative controller (PID controller or three term controller) is a control loop feedback mechanism widely used in industrial control systems and a variety of other applications requiring continuously modulated control. A PID controller continuously calculates an error value e(t){\displaystyle e(t)} as the difference between a desired setpoint (SP) and a measured process variable (PV) and applies a correction based on proportional, integral, and derivative terms (denoted P, I, and D respectively) which give the controller its name. posted by Arun Gupta

    Chemical kinetics is the study and discussion of chemical reactions with respect to reaction rates, effect of various variables, re-arrangement of atoms, formation of intermediates etc. There are many topics to be discussed, and each of these topics is a tool for the study of chemical reactions. posted by Arun Gupta

    Chemical reaction engineering (reaction engineering or reactor engineering) is a specialty in chemical engineering or industrial chemistry dealing with chemical reactor. Frequently the term relates specifically to catalytic reaction systems where either a homogeneous or heterogeneous catalyst is present in the reactor. Sometimes a reactor per se is not present by itself, but rather is integrated into a process, for example in reactive separations vessels, retorts, certain fuel cells, and photocatalytic surfaces. The issue of solvent effects on reaction kinetics is also considered as an integral part. posted by Prashant Swami

    A furnace is a device used for high-temperature heating. The name derives from Greek word fornax, which means oven. The heat energy to fuel a furnace may be supplied directly by fuel combustion, by electricity such as the electric arc furnace, or through induction heating in induction furnaces. A refractory material is a material that retains its strength at high temperatures. ASTM C71 defines refractories as "...non-metallic materials having those chemical and physical properties that make them applicable for structures, or as components of systems, that are exposed to environments above 1,000 °F (811 K; 538 °C)." posted by Prashant Swami

    A shell and tube heat exchanger is a class of heat exchanger designs. It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. The set of tubes is called a tube bundle, and may be composed of several types of tubes: plain, longitudinally finned, etc. posted by Prashant Swami

    A waste heat recovery unit (WHRU) is an energy recovery heat exchanger that recovers heat from hot streams with potential high energy content, such as hot flue gases from a diesel generator or steam from cooling towers or even waste water from different cooling processes such as in steel cooling. posted by Prashant Swami

    A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of closed circuit dry cooling towers, rely solely on air to cool the working fluid to near the dry-bulb air temperature. Common applications include cooling the circulating water used in oil refineries, petrochemical and other chemical plants, thermal power stations and HVAC systems for cooling buildings. The classification is based on the type of air induction into the tower: the main types of cooling towers are natural draft and induced draft cooling towers. Cooling towers vary in size from small roof-top units to very large hyperboloid structures (as in the adjacent image) that can be up to 200 meters (660 ft) tall and 100 meters (330 ft) in diameter, or rectangular structures that can be over 40 meters (130 ft) tall and 80 meters (260 ft) long. The hyperboloid cooling towers are often associated with nuclear power plants,[1] although they are also used in some coal-fired plants and to some extent in some large chemical and other industrial plants. Although these large towers are very prominent, the vast majority of cooling towers are much smaller, including many units installed on or near buildings to discharge heat from air conditioning. posted by Prashant Swami
