VAPORIZER IN PROCESS INDUSTRY

Vaporizers are heat exchangers which are specially designed to supply latent heat of vaporization to the fluid. In some cases it can also preheat the fluid then this section of vaporizers will be called upon preheating zone and the other section in which latent heat is supplied; is known as vaporization zone but he whole assembly will be called upon a vaporizer. Vaporizers are called upon to fulfill the multitude of latent-heat services which are not a part of evaporative or distillation process. There are two principal types of tubular vaporizing equipment used in industry: Boilers and Vaporizing Exchangers . Boilers are directly fired tubular apparatus, which primarily convert fuel energy into latent heat of vaporization. Vaporizing Exchangers are unfired and convert latent or sensible heat of one fluid into the latent heat of vaporization of another. If a vaporizing exchanger is used for the evaporation of water or an aqueous solution, it is now fairly conventional to call...

FURNACE IN CHEMICAL INDUSTRY

A furnace is a device in which chemical energy of fuel or electrical energy is converted into heat which is then used to raise the temperature of material, called the burden or stock, placed with in the furnace. Furnace that is operating at temperature below 1200 o F (650 o C) are commonly called ‘oven’. In ceramic industry furnaces are called ‘kilns’. In the petrochemical and CPI (Chemical Process Industries) furnaces may be termed as ‘heaters’, ‘kilns’, ‘after burners’, ‘incinerators’ or ‘destructors’ . Classification of Furnaces Furnaces are classified from different points of view in order to have an idea of representative types of various industrial furnaces which mainly comprise of three main portions: 1. The fire place where combustion of fuel takes place. 2. The working chamber or furnace proper where heat is transferred from products of combustion to the material under heating. 3. ...

PROPANE PROCESSING IN OIL AND GAS INDUSTRY

Chiller As explained earlier that Propane is used as the refrigerant in chiller. Gasses from the gas/gas and gas/liquid enter into the chiller where they are passed through the tubes while propane is on shell side. Excessive drop in temperature occurs here causing heavier hydrocarbons to condense out as propane after exchanging heat vaporizes. MYCOM Compressor After cooling raw gas in chiller, vaporize propane from suction scrubber enters into the MYCOM compressor, which is reciprocating economized screw compressor. The suction pressure remains around 50 KPa and discharge pressure is around 55/56 KPa, which is controlled by pressure control valve (PCV). With gaseous propane lube oil also enters into the vaporize propane which act as a lubricant as well as coolant. This mixture enters into the refrigerant/oil separator, in which lube oil is separated from gaseous propane. After this propane enters into the propane accumulator and then into the FIN fan condenser. Fan Con...
