LPG GAS PLANT

Introduction of LPG Gas Plant:

What is Liquefied Petroleum Gas?

LPG is the most efficient form of energy with high combustion efficiency. LPG (Liquefied Petroleum Gas) is a collective name for a number of petroleum gases consisting of propane, butane or mixtures of these gases that can be condensed to form a liquid. There may be small concentrations of other C3, C4 and C5 hydrocarbons such as propylene, iso butane, butylene, isobutylene and iso pentane. When stored under pressure it becomes a dense liquid allowing large quantities of gas to be stored in a relatively small space. LPG exists as a gas at normal atmospheric pressures and temperatures but may be liquefied by the application of moderate pressure. If the pressure is released, the liquid will revert back to vapor.

LPG as a liquid is colorless and as a vapor, cannot be seen. Pure LPG has no distinctive smell so for safety reasons, a stanching agent is added during production to give it a pungent, unpleasant smell and so aid detection by the human nose at very low levels. LPG is non-toxic but at very high concentrations in air, LPG vapor acts as an anesthetic and subsequently as an asphyxiate by diluting or decreasing the available oxygen. When LPG is mixed with air, a highly flammable mixture is produced. The flammability range is between 2% to 11% by volume of gas to air. Outside this range, any mixer is either too weak or rich to propagate a flame. One volume of liquid will produce approximately 250 volume of gas vapour. LPG vapour is heavier than air. Any escape will find its way to the lowest level where it can remain and form a flammable mixture; Therefore, LPG vessels must be sited away from drains and appliances and must not be sited in basements or cellars.

Our introduction :-

We BNH Gas Tanks India are manufacturer and exporter of LPG Gas Plant at cheap cost. The plants are as per customer's requirement.

LPG Filling Plant

Project Design
The proponent intends to build modern medium size LPG storage and filling plant in Kisumu to fill cylinders for the LPG marketing companies on throughput agreement basis. The depot will be designed in a modular form with an initial storage capacity of 70 metric tonnes. Thereafter an additional tank will be added to bring the capacity to 140 metric tonnes. The depot will be constructed in accordance with all the existing legal and technical requirements. The plant will be designed to refill LPG for all the customers in the Western Kenya and parts of the Rift Valley province. It will source LPG from Kenya Petroleum Refinery Limited and importers and transport it to the warehouse by road in LPG tankers trucks.

The filling container will be equipped with three electronic filling machines to fill 6kg, 12kg, 25kg and 35kg cylinders. Two (2) machines will be used to fill the 6kg and 12kg cylinders and one (1) machine will be dedicated to the 25kg and 35kg cylinders. The LPG storage will be composed of one (1) LPG tank with a geometrical capacity of 70m³. LPG tank is designed to store mixture of Butane/Propane (with maximum propane content of 30%) and is designed under the AD2000 code. The study of the storage plant is based on the rules of fittings and exploitation of first and second class liquefied hydrocarbon storage depots.

The product will be a mix of propane and butane, therefore the design is made for LPG with a maximum propane content of 30%. The equipment will be supplied from India and will consist of LPG Pumps, piping and accessories, LPG connections and components, explosion proof electrical fittings designed for use in machines in hazardous areas, equipment under pressure viz LPG receivers and piping, etc. It is a modern gas filling plant in western Kenya, with capacity of at least 3 cylinders per minute with Bulk storage capacity of 259,200 cylinders within 24 hours.

The LPG plant includes LPG fractionation system, compressors, refrigeration system, and hot oil heating system, mini LPG storage, power generators and other supporting units.

All electrical components, Instrumentation and control panels shall be flameproof, certified by CMRS, Dhanbad, & approved by CCOE, Nagpur.

LPG Vaporizer

1) The LPG vaporizer must be firmly fixed on the solid stand or concrete foundation. 
2) Leave enough space around the LPG vaporizer for easy access for overhaul inspection
    & maintenance. 
3) Execute the piping works properly in conformity with fluid pressure & the piping
    size to protect the LPG vaporizer form overpressure. 
4) In case that the excess Butane contained gas is used, the gas may be
    re-condensed at the part of high and medium pressure piping lines at a cold district
    in the winter season. 
5) The electrical works consist of the explosion-proof works for power supply to
    the heater and the flexible fittings and sealing fitting must be used for connection of
    power supply. 
6) The detail works are described on the electric wiring works.

A device other than a container which receives LP-Gas in liquid form and adds sufficient heat to convert the liquid to a gaseous state.

BNH Gas Tanks manufactures liquid Propane/Butane vaporizers with capacities from 168 gallons per hour (322 kg/h) to 14000 gph (28000 kg/h). To meet the requirements of customers and particular applications around the world, we are employing a variety of design concepts and configurations. Their heat source can be hot water (Water Bath Vaporizers; Circulating Hot-Water Vaporizer) or steam (Steam Vaporizers). The vaporizers are manufactured to the rigid codes of the American Society of Mechanical Engineers (ASME), the latest edition of NFPA #58 and/or #59, and most are approved for Factory Mutual (FM) or Industrial Risk Insurers (IRI) installations, in addition to approvals by Canadian Standards Association (CSA), American Gas Association (AGA), and Canadian Gas Association (CGA). European CE Approval, including ATEX, PED, and other applicable Directives, is available for all Water Bath Vaporizers.

As a manufacturer, we go far beyond the requirements and codes and are continually working to produce equipment with the most modern engineering techniques available.

WHAT IS A PROPANE / BUTANE / LPG VAPORIZER?

LPG (Propane, Butane, or Propane / Butane Mixture) at ambient pressure (above its boiling point temperature) is a gas that is stored in pressurized containers (tanks) in liquid form. The space in the tank that is not filled with liquid is occupied by vapor. As this vapor is being used as fuel for connected equipment (burners, heaters, etc.), liquid LPG must vaporize (change its state from liquid to gas) to occupy the space above the liquid.

Any time a change of state occurs, energy is required. If the ambient temperature is above the boiling point of the LPG (Propane -44°F / -42°C; Butane 32°F / 0°C at ambient pressure; see chart for the boiling temperature of LPG at various pressures), this energy is transferred in the form of heat from the ambient air through the steel walls of the storage tank, into the LPG. As the heat is transferred from the ambient air to the vaporization process, the ambient air "looses" this energy and cools down.

The amount of heat that is transferred into the LPG determines the rate of vaporization. As the ambient air cools down, the rate of vaporization slows down, and stops completely when the ambient air is at the same temperature as the boiling point of the LPG. Therefore, naturally occurring vaporization cannot be used for large gas loads, or in low ambient temperatures.

A vaporizer is designed to receive the liquid LPG and raise its temperature (heat the liquid) well above the boiling point at the delivery pressure. In other words, a vaporizer generates the (heat) energy that is required to maintain the gaseous state of the LPG.

There are two major types of propane vaporizers: Vaporizers that supply a small portion of the vaporized LPG as fuel for the burner that supplies the heat for the vaporization process (i.e. Water Bath Vaporizers); and vaporizers that use an outside source of heat, such as steam or hot water, to vaporize the propane.
