Gas Cylinder Manifolds

Why a Gas Distribution System?

If you think about it, most of the gases are toxic, flammable, corrosive, or often a combination of these. Other gases constitute a different hazard-such as asphyxiation, anesthesia or, simply, pressure. For some customer installations, a simple pressure regulator or control valve will not suffice, for example:

  • Where the gas, for physical considerations of space or location, must be stored in an area remote from point of use.
  • Where two or more cylinders are coupled together for high flow-rates.
  • Where a regular purge cycle is required between gas uses or at cylinder change-over.
  • Where safety considerations with a toxic or flammable gas require that equipment and/or pipelines containing that gas should be totally isolated from the working environment.
  • Where gas flow, pressure or temperature requirements are such that a very sophisticated means of gas control is required, especially in bulk gas installations.
  • In this there is clearly a need for a specialist designed Gas Distribution System.

Gas Mixing Systems and Gas Blending Systems

The Gas blending system can mix and blend two or more gases with each other at a predefined ratio. It can be used for blending or to dilute gases to generate precise calibration gas standards, production gas mixtures or to create gaseous atmosphere. The gases can be mixed in a ratio of 1:1 upto 1: 1000.

The system automatically dilutes high concentration certified gas cylinder to a wide range of of concentrations from high percentage to low parts per million.

The system is operated by controls set at front panel. After entering required concentration, the system automatically mixes gases connected to the ports to generate required mixture.

Gas Mixing System

The gas mixer precisely dilutes and blends high concentration certified gas cylinders to generate precise gas calibration standards, create gaseous atmospheres, or produce gas mixes for analytical research and process gas mixture purpose.

The mixer can produce complex mixes containing upto seven individual gases in a balance gas. The mixer produces gases from a percentage level to parts per million level for single or multipoint calibration.

The mixer consists of control instrumentation and mixing zone. Commands are entered from front panel. Optional RS232 control with computer controlled command mode is also available.

  • Reduced cost of Gas Standards: Calibration gases is a costly affair. The mixer reduces / stops costly expense of calibration gases needed for calibration of instruments. Also reduced inventory of gas cylinders due to broad range of dilution ratios. It enhances profitability in process industries due to eliminating costly process gas mixtures. The mixer can be used for online gas mixing.
  • Wide Dilution Ratio: Broad range of dilution ratios (1:1 upto 10000:1) allows user to significantly reduce the number of gas cylinders needed to perform compliance tests.
  • State of the Art Software: Automatic calculation of dilution and span gas flows based on the concentration commanded by the user eliminates the need for manual computation allows rapid transition from point to point and scale to scale.

A gas regulator or a pressure regulator or simply regulator is a device that automatically cuts off the flow of gas at a certain pressure. Widely used in gas plants or gas systems, regulators are meant to reduce the pressure from a high pressure source to a safe working pressure for use. It is a very essential equipment to bring about a positive control of the pressure in a gas stream. A safety tool, it reduces high-pressure gas in a cylinder or process line to a lower level that is usable and maintain pressure in a gas delivery system. In other words, regulators are used to control delivery pressure only. Regulators are suited to most industrial grades of gases and fluids up to 99.99% purity (which includes helium, hydrogen, acetylene, argon, oxygen and CO2).

Basic Operating Components
In gas pressure regulators, there are three basic operating components, which work together to obtain pressure reduction. They are as follows:

  • A loading mechanism: The setting of the regulator delivery pressure depends on loading mechanisms. The loading mechanism usually make use of a spring and with turning of the regulator's hand knob, the spring is compressed. Force is applied on the spring and transferred to both the sensing element and the control element to achieve the outlet pressure.
  • A sensing element: Sensing elements imply the components which sense the force put on the spring, which in turn set the delivery pressure. A diaphragm, either constructed of elastomers or metal, is usually as the sensing element and it is this element which communicates this change in force to the control element.
  • A control element: The control element in gas regulator is the valve that leads to the reduction of inlet pressure to outlet pressure. With the turning of the gas regulator's hand knob, there is compression of the loading mechanism, which displaces the sensing element (diaphragm) which in turn pushes on the control element, causing it to move away from the regulator's seat, and provide the flow and pressure required.

Parts of a Typical Regulator

Types of Regulators
There are four main types of gas pressure regulators:

  • Line Gas Pressure Regulators:Line regulators are point-of-use gas pressure regulators. They serve low-pressure pipelines, used with high-pressure cylinder regulators. The line pressure regulators limit the inlet pressure from 250 to 400 psig.
  • General-purpose Gas Pressure Regulators:It is a common type of gas pressure regulators, specially designed for economy and longevity, and preferred for noncorrosive general plant, pilot plant, and maintenance shop applications.
  • High-purity Gas Pressure Regulators: They provide diffusion, resistance, and easy cleanup. inboard diffusion eliminated by metal diaphragms and high-purity seats and seals. Special service gas pressure regulators: Specialized regulators are specifically constructed for specialized applications like high-pressure, ultra high-pressure, oxygen, acetylene and fluorine service, and corrosion service.

Regulators: Design Types
Regulators are generally classified into 3 design types types:

  • With no gauge: They are economical general purpose regulators and here monitoring of the gas supply and outlet pressure is not needed.
  • One gauge: These regulators show the inlet pressure only but can be supplied to show the outlet pressure instead.
  • 2 gauges: This model shows accurate pressure reading of both inlet and outlet pressures and is the most popular design used today.

On the basis of the above design types, gas regulators can be classified as follows:

  • Single-stage Regulators: : They give good pressure and flow characteristics. Suitable for short run analytical work, engineering and industrial applications, these regulators are available in a range of inlet and outlet pressures (up to 6000 psi) to suit most gases.
  • Two-stage Regulators: : Also referred to as multi-stage regulators, they have all the features of single-stage regulators. Besides that with the two gas reduction chambers, they provide additional safety and specific control over the complete inlet pressure range. Multi-stage regulators are capable of working with cylinder pressures up to 300 Bar with safety and precision control. They provide the ultimate answer to gas pressure requirements, and can be found in many diverse applications including gas plants, life support systems, laboratory supply systems, food and drink processing, and high tech manufacturing.
