One of our areas of activity is recycling unusable wastes which are created during the operations

of ion-free water production units.

In order to produce boiler feed-water most petroleum, chemical and industrial complexes use

ion exchangers to deionize raw water and some amount of unusable waste is created during

every cycle of producing ion-free water.

Our institute

after conducting comprehensive investigations and studies on a waste-recycling project has

managed to develop a system which is capable of recycling about 93% of waste in the shortest

time and with the lowest cost. The recycled waste can be used again and will consequently save a

considerable amount of water consumed in petroleum, chemical and industrial complexes.

This is our offer :

If ion exchangers are used to produce ion-free water in the complexes

affiliated with your country and in case you have not yet come up with a solution to

recycle their wastes, we would like to extend our cooperation with you through

installing and operating the above-mentioned new system.

Here is a description of the importance of using ion-free water to supply feed water for high-

pressure boilers:

All kinds of natural water contain different concentrations of soluble salts which dissolve and

create charged ions. Positively-charged ions are called " cations " , and negatively charged ions

are called "anions". The ionic impurities can seriously damage the proper functioning and


efficiency

of boilers or other process systems. Increasing sediments and the formation

of extra deposits inside pipes will increase their temperature and can result in catastrophic

damages, decrease in production level or unexpected stops.

Hard ions such as magnesium and calcium and other ions, as well as carbon

dioxide and silica need to be completely removed from water in order to produce "feed water"

for boilers used in complexes such as refineries, power plants and chemical and industrial

complexes.

The application of ion exchangers in industries and petroleum-chemical

complexes:

In order to produce feed water for high-pressure boilers as well as many other

process systems it is necessary to remove all extra ions from raw water through

transferring them to a solid material called ion-exchanger. If ions are absorbed by ion-exchangers

(cationic and anionic resins), non-harmful particles are separated to the extent that the capacity

of ion-exchangers allow.

Ion-exchangers have a limited capacity, known as “exchange capacity”, to keep ions in their

structures. Therefore ion-exchangers are often saturated by undesirable ions.

They are then washed using a strong reducing solution containing non-harmful

ions. Finally undesirable ions are replaced and exchanging materials will return to a usable state.

How waste materials are produced in ion-exchanger units:

The operations of ion-exchangers are chemical process cycles. A full cycle includes

pre-servicing, operating, backwashing, reducing and rinsing.

This cycle produces large volumes of unusable waste.


Explaining a computational table:

According to this table in a small unit of ion-free water production with the

capacity of 200000 liters per 20 hours, about 36663.39 liters of unusable waste was created.

Features and production capacity: Volume of cationic resin exchanger: about 2200 liters

Volume of anionic resin exchanger: about 1500 liters

Volume of cationic

and anionic resin exchanger (Mixed bed): about 1000 liters

FLOW=10 M3/H

Unusable waste

produced in the operation is about 36663.39 liters. Running this project will save as much as

1561249.575 liters of water annually in a small unit.

It is noteworthy that the measured amounts are those of a small industrial unit .The

volume of waste produced by major units like refineries and industrial and chemical

complexes are many times larger.

Advantages of our new design:

a) Low cost in supplying materials

b) Easy installation and operation

c) Recycling about 65% of all waste in the first phase in the shortest period of time.

d) Recycling about 72% of all waste in the second phase requiring more time than the previous

phase.

(Total: about 93% of all waste is recycled.)

e) Significant savings in water consumption for water power plants, refineries and chemical-

industrial complexes

of the remaining 3 percent only 1 percent is accessible.
