Grease Kettles are pressurized or unpressurized vessels that are used to manufacture GREASE, a lubricant. Lubricating grease, a substance used in manufacturing processes is produced by steaming, heating, mixing and then cooling the ingredients. Grease refers to a semi-solid lubricant that has a higher viscosity than oil. It is typically made from calcium, sodium or lithium soap (salts of fatty acids) and mixed with mineral or vegetable oil.

New Multifab Engineers Private Limited manufacture and supply grease kettles of various capacities and operating pressures, ranging from atmospheric to vacuum. In addition to this, we have manufactured grease kettles for varied applications and with different designs of agitators. We are Mumbai based suppliers and exporters of grease kettles. We have had repeat orders from satisfied customers.

Please see the Certificates section to read testimonials from our satisfied customers about the quality of our Grease Kettles.

Lubricating greases can keep dust and air away when used as sealants and also decrease friction in machinery moving parts such as bearings or gears. They are also used as substitutes for oil as a lubricant. In cases where oil cannot be used, like operations which must be sterile for the medical, pharmaceutical, food and beverage industries, greases prove to be a superior choice. Industrial greases are very fire resistant, and can be made from either synthetic or natural ingredients.

Grease used in a variety of industries is manufactured using Grease Kettles. Grease kettles come in many different sizes, and can hold anywhere from 20 to 200,000 Kg of grease at a time. Most smaller kettles are made for short cycles and are used in testing laboratories. Larger kettles can have a large variety of operating pressure and temperature conditions as well as agitation mechanisms.

Sources of air pollution in grease plants:

Air pollution and health effects of pollutants present in air are a concern for industries and policy makers alike. Amongst the criteria pollutants, particulate matter suspended in air is a potent threat because of the irreversible damage it can cause to living organisms. Mists are dispersions in a gas of liquid particles less than about 10 microns in size. Air pollution in the form of mist i.e. suspended oil drops in steam occurs at the following points in grease plants:

1. Pressure Cooking Grease Kettle:  When the steam is vented at the end of cooking the pressure is reduced from 6 to 8 bars to atmospheric.  In case this is done suddenly (within a minute) the quantity of oil droplets in the mist is higher. If done gradually over a time of 10 minutes the carry over of droplets is less. A little quantity may escape during addition of solids (HCO & LiOH).
2. From Mixing Grease Kettle:  The mist escapes to atmosphere when the batch is being blown, that is transferred, from pressure kettle to mixing kettle. This may continue till all the water evaporates from the grease.
3. From Atmospheric Cooking – Mixing Grease Kettle:  In this case the saponification and further addition of oil is carried out in the same kettle.  The mist will continue to escape from atmospheric kettle as soon as the temperature rises above 100 °C.  It is a normal practice to add water when the batch is at 140 °C to ensure completion of saponification.  The temperature is then raised above 200 °C. During this entire period mist will be escape from the kettle.

A charge hole (or manhole) is provided for addition of solids (fat and alkali) which normally remains open during the batch; it is not fume tight even when closed.

Air Pollution Control in Grease Manufacture Plants

CONTROL METHODS FOR AIR POLLUTION

Air pollution control can be achieved by the following two methods:

1. Provision of a hood over the charge hole/manhole – typically used in many manufacturing locations
2. Suction from a nozzle situated diametrically opposite on the vessel top to the charge hole.  The air velocity entering the vessel is designed so that no mist escapes the kettle – this is a new design and gives improved performance. This system has been designed by New Multifab Engineers Private Limited. It has been installed at various Grease Manufacturing companies along with Grease Kettle manufactured by us.

The table shows comparison of these two systems.

Description of Scrubber system

The mist drawn from grease kettle is passed through a scrubber. The scrubber is of counter-current direct contact type, wherein water is sprayed from the top. The spray water is a closed loop system consisting of a Pump – Heat Exchanger – Scrubber – Separator Vessel. The water needs to be cooled as it is condensing steam. The latent heat of evaporation is to be removed partially as some of it is removed by cold air entering the kettles.

Design of Scrubber

The entry nozzle may be tangential or perpendicular from side of vessel. Water is sprayed from top. Water containing oil droplets is passed through a separator vessel. The pump suction is from the bottom of separator vessel. The heat exchanger (either water cooled or air cooled) is situated between pump and scrubber.

Scrubber for Grease Kettle

Scrubber - vessel

Design of Heat Exchanger:

The Heat Exchanger is to be designed to accomplish the following:

1. Removal of latent heat of evaporation of water
2. Cooling of air mist mixture to less than 70 °C

Benefits of Control System

1. Environmental Legal Compliance
   1. At present, there are no air quality standards for indoor air, that is, air within the working area. However, legislation is expected in the future which will limit the amount of particulate matter present in air in closed working areas. Use of the new system will give user confidence of compliance to upcoming legal requirement
   2. Mist escaping to the atmosphere is a severe environmental hazard and is punishable under The Air (Prevention and Control of Pollution), Act 1981 and its subsequent amendments. Use of negative pressure – scrubber system will ensure that oil is recovered and not emitted into the atmosphere. This system, designed by New Multifab Engineers Private Limited for Grease Manufacturers will assist them in legal compliance.
2. Cost savings
   1. Oil that is lost with mist into the air is not recoverable – that is, it is lost from the process.
   2. With the use of negative pressure – scrubber system, loss of oil can be prevented. Recovered oil can be reused in the same batch or subsequent batches.
   3. Negative pressure – Scrubber system also consumes less energy than conventional hood system. Therefore, operating costs are much lower.
   4. The negative pressure – scrubber system designed by New Multifab Engineers Private Limited can be installed in conjunction with any grease manufacturing kettle. It has already been installed at many grease manufacturing plants in India and in other countries.
