Acetate plant is used to produce ethyl acetate and butyl acetate. The esterification reaction is done using this acetate plant. Acetic acid and ethyl alcohol are sent in a fixed proportion through a preheater to a kettle reboiler. The reaction products are carried to the top of the column as an azeotrope, condensed and pass to a decanter. The top over flow from the decanter is partly given as reflux. The remaining part of the top over flow along with bottom of the decanter is sent to a mixer. The mixer also receives top product of the recovery column. The contents of the mixer after through stirring are sent to a settler. Top over flow from the settler is sent to ethyl acetate column. The product ethyl acetate is drawn from the bottom.

The acid cooling system plays an important role in determining the efficiency and safe operation of the plant. It is used for lead acid battery filling applications. The filling of batteries with sulphuric acid in high ambient summer temperatures causes fast rates of in-battery reaction with evolution of corrosive fumes and distortion of the plastic battery casing. The in-line polyethylene-cooling unit would typically reduce ambient temperatures of 35ēC to a filling temperature of 0ēC hence reducing reaction rates and eliminating distortion of the battery casing. This allows faster filling of batteries without the evolution of corrosive fumes and prevents jamming of battery conveyor systems causing production down time.

Air control regulators in multiple burner systems hold constant air fuel ratio and mixture pressure with reducing burner port area of up to 90%. The top main diaphragm chamber is referenced through a bleed loader set for the desired burner mixture pressure. The bottom main diaphragm chamber is referenced downstream of the flow mixer or flanged mixing tee. Mixture pressure and air-fuel ratio are held constant as burners are turned off. It is available in various sizes and types.

Air/gas mixers are designed for low-pressure drop operation. Combustion air delivered through a control valve is metered through a precision machined orifice. Controlled air pressure is impulsed to the top of the gas balanced zero regulator. The zero regulator outlet pressure is always the same as the controlled air pressure. An adjustable gas orifice sets the gas fuel flow rate. The pressure interlocked system maintains equal air and gas pressure drops at all flow rates. Air-gas ratio is constant over the entire turndown range of the system. These mixers selections are based on blower air pressure available, mixture pressure required at the burners, BTU/hr. input, percentage primary aeration and turndown ratio required.

Aircraft refueling system is a refuelling equipment for aircraft, and in particular to a cellular system for refuelling long range aircraft crossing oceans. A floating refuelling station for aircraft includes at least one container hull, which is movable and a sloping platform supported by the container. The sloping platform has at least one runway thereon for take off and landing of aircraft. The container hull may be used to store aviation fuel for refuelling the aircraft, the movability of the hull may be used to orient the runway with respect to the direction of the wind and the runway has a ramp section inclined at an angle to help slow down landing aircraft and/or to help speed up aircraft taking off. The height of the runway above the sea surface needs to be sufficient to accommodate any loss of buoyancy due to outpourings of gas from the sea bed.

Alcohol plants are used for alcohol production. It is designed to handle a variety of raw materials. The technology will be modified to increase alcohol fermentation from the corn starch, which reduces water consumption and develops DDGS fodder. The rate of CO2 recovery will be increased to 60%. This plant is also used to prepare sugar, molasses, ethanol, methanol, fuel and breweries.

Ammonia handling equipments include unloading stations, storage tanks & accessories, ammonia feed forward pumps, ammonia process control unit, ammonia distribution manifolds, and ammonia injection grid.

Ammonia injection grid offers a plurality of air foils across a flue conveying flue gas. It is located in the flue leading to the SCR catalyst at a point far enough upstream to ensure optimal flue gas and reagent distribution across section of the catalyst. The primary design parameters for the ammonia injection grid involves total ammonia delivery capacity, header velocity, nozzle area concentration and injection velocity.

Ammonia plants are used to produce ammonia. The primary purpose of the ammonia plants is to supply liquid ammonia to the di-ammonium phosphate (DAP) plant, for the production of DAP/MAP fertilizer. These plants comprise of several units that include natural gas compression and desulfurization, reforming, waste heat recovery and boilers, CO shift conversion, CO2 removal and methanation, syngas compression, ammonia synthesis, refrigeration, ammonia and hydrogen recovery, ammonia storage, and shipping facilities.
