CHEMICAL PLANT
A RARE OPPORTUNITY TO ACQUIRE
Due to the reorganisation of a substantial chemical site in UK a rare opportunity presents itself to acquire first class chemical assets at a very attractive price in first class condition.
Brief details are supplied here and more comprehensive data can be made available on request including flow diagrams. Plant visits can be arranged. Each piece of plant is either still in use or has been in use within the immediate past few months as the operations are wound down.
PLINKE SULPHURIC ACID REGENERATION PLANT AND TECHNOLOGY
Originally brought on stream in 1994 this 100ktpa plant is in excellent working condition producing 96% water white acid from minimum 52% strength input.
The plant is designed for the treatment, stripping and concentration of spent sulphuric acid from different process origins such as MNT, NTSA, CM and SBA to produce purified sulphuric acid of 96% concentration as stated above.
The NOx ?containing effluent gas is purified by pressure absorption and nitric acid is recovered.
Process.
Pre-treatment, stripping and pre-concentration of spent acid is achieved in atmospheric conditions using thermo-siphon systems. The pre-concentrated sulphuric acid is further treated in the Plinke-Savaco-HT Process which is a vacuum rectification process at relatively high temperature, to produce a purified acid of 96 wt % minimum concentration of H2SO4.
The Nox-containing gases generated during the treatment and concentration process are absorbed under pressure conditions using water and atmospheric air.
Process steps and additional units
Pre-treatment and concentration (SAPC) Sulphuric acid preconcentration under atmospheric conditions to approximately 74 wt%
Stripping and further treatment and concentration (STRIP) A stripping unit in which the acid is concentrated to approximately 74 wt% and the generated vapours are used for stripping out some of the organics.
Sulphuric acid medium concentration (SAMC) Sulphuric acid medium-concentration unit up to 85% under vacuum conditions at approximately 70 t0 80 mbar a
Sulphuric acid high concentration (SAHC) Sulphuric acid high-concentration unit up to 96 wt% which is operating under vacuum conditions of approximately 75 to 80 mbar a
and
Nitric acid storage and treatment system NSA treatment system NOx-absorbtion (ABS) Thermo oil system (TO) Chiller unit package Instrument air compressor Oil separator.
The Savaco ? HT Process enables purification of the final product from organic impurities to be achieved. The combination of pre-treatment and stripping of the sulphuric acid vapours of the second stage, as well as the final treatment of the sulphuric acid product result in a highly purified product.
Instrumentation and control
The plant is operated from a control console. Normal day-to-day operation will be from a remote control room by computer keyboard. Start-up and shutdown of machines as well as the start-up of the evaporation process are carried out remotely from the keyboard. Emergency shutdown is carried out automatically or manually. All important process parameters are controlled; the corresponding set points are fixed by the operator. After constant operating conditions have been reached and all controllers have been switched over at the keyboard to ?Automatic' the plant is thereafter controlled automatically.
Heating and cooling
There is a complete thermo oil generator with maximum heat capacity of
5500 kW. Consumption of natural gas is approximately 560 mn3/h (nominal). Consumption of gas oil is approximately 500mn3/h (nominal). Chiller unit cooling capacity 290 kW.Price

25 SQUARE METRE EIMCO TOTALLY ENCLOSED ROTARY VACUUM PRECOAT FILTERA continuous fireproof centrifuge 8 feet in diameter and 11 feet face totally enclosed having 25 square metres of filter area. Suitable for fine chemical use and pharmaceuticals. Original year of installation
1993.General description
Filter drum, deck and piping are in AISI 304L stainless steel and the screen is type AISI 304 stainless steel 25 x 110 wire (mesh). The filter tank and hood are in AISI 304. Other materials are plain carbon steel unless specified otherwise. All gaskets are nitrile rubber or equal. Packing for various stuffing boxes are rubber core with Teflon jacket.
The tank is constructed from 5mm AISI 304L plate with external structural steel reinforcing. The shell is provided with one horizontal bolting flange and gasket, insulation stops and with dowels for matched fit to receive the totally enclosed hood. The structural steel framework of the shell is provided to form supports for mounting the filter on a concrete or structural steel base.
A totally enclosed hood with 8 inspection ports is made of 5 mm AISI
304L plate with four lifting lugs. Six light ports with explosion proof lamps are fitted. One hinged access door is placed at the discharge end to replace the scraper edge. The door has air cylinder opening.The cylindrical surface of the drum, with the filter media mounted on, forms the filtering surface. The filtrate liquor, drawn through the media, is drained by a piping system internal to the drum. Solids suspended in the slurry remain on the surface of the media and form the cake. AISI 304L is the stainless grade throughout.
This is a first class piece of chemical kit in good working order.
