Most Common Types of Petrochemical Valves

Valves are used in a variety of industry types in order to control the flow and pressure of liquid, gas, oil, vapor, etc. They effectively control the piping system, which is especially critical when working with chemicals and extreme pressure/temperature as you do in the petrochemical industry.

While there are many types of valves out there, this article is going to detail five of the most common petrochemical valves. We’ll detail how the valve works and what it does for the petrochemical industry.

• Trunnion ball valve
• Rubber seated ball valve
• Butterfly valve
• Plug valve
• Air-release valve
• Vacuum valve
• Swing check valve
• Tilted cushion valve
• Swing check oil cushion valve
• Swing flex valve
• Gate valves
• Automatic Shutoff valves
• Check valves
• Globe valves

Valves and their Role in Petrochemical Industries

Petrochemical industries are not limited to the production of only oil and gas. They are responsible for producing and storing a wide range of petrochemicals such as acetylene, benzene, ethane, methane, propane, and hydrogen from other products like elastomers, plasticizers, solvents, oils, etc. are derived.

Inside a petrochemical environment, there will be a few hundred, if not thousands of valves that take on the following functions:

• Controlling the flow of media such as oil, gas, steam, water, and hydrocarbons.
• Modulating the flow of media through pipelines.
• Controlling the direction of the flow through pipelines.
• Regulating the pressure in a particular process.
• Protecting the pipelines from mounting pressure.
• Filtering particles or debris in the medium and protecting the equipment.
• Without valves, the environment in a petrochemical plant could become hazardous and vulnerable to catastrophic events.

The refining industry uses an industrial process where crude oil is processed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, and liquefied petroleum gas.

Most Common Types of Refinery Valves

• Control Valve
• Butterfly Valve
• Trunnion Ball Valve
• Floating Ball Valve
• Check Valve
• Globe Valve

The refining industry has undergone many changes, from processing methods to the duration they operate. These changes, along with the emergence of low sulfur fuel specifications, the requirement to process lower grade crude, and the need to convert more bottom-of-the-barrel residuals, have put an extreme demand on isolation and control valves. ZECO Valve has responded to these challenges by developing a combination of diverse trim configurations and high-quality coatings for use in high temperature, high pressure, erosive, corrosive, viscous, and coking/asphaltene applications

What is Coke Plant?

To make steel in a blast furnace, coal must first be turned into coke. Coke has a dual role in the steelmaking process. First, it provides the heat needed to melt the ore, and second, when it is burnt, it has the effect of ‘stealing’ the oxygen from the iron ore, leaving only the pure iron behind. In the coking plant, coal is heated in the absence of oxygen to 1250c. This removes any impurities in the coal, resulting in coke, which is a porous substance that is nearly all carbon.

How does a Coke Plant Works?

Coal is the main ingredient used to make coke. Iron is produced by inputting coal into a blast furnace. However, coal cannot be put directly into a blast furnace because of all the harmful by-products that come from that. So, there is an intermediate process that occurs. Coal is converted into coke first. Coke is used as fuel in a blast furnace. It plays an important role in the chemical processes that take place in a blast furnace.
Coal is heated to about 1250 degrees Celsius in the coke ovens. This process is referred to as ‘dry distillation’ because these coke ovens are oxygen-free, so the coal does not actually burn. This process takes around 18 hours to convert 35 tons of coal into 25 tons of coke.

After heating up the coal into coke, the coke is then unloaded from the oven by a pusher machine. The pusher machine has a pusher arm that puts the coke into a car that takes the coke to a coke quenching tower. Here, the coke is quenched with water. The coke is then taken to a coke wharf, where the remaining water evaporates. A reclaimer then feeds the coke from the wharf to a conveyor belt, which transfers the coke to the crushing and screening station. The finished product is about two-thirds the weight of the original raw material.

During the distillation process, a large amount of gas and smoke is generated, which, after purification, creates coke oven gas, and other by-products such as ammonia, tar, sulfur, naphthalene, and benzol. The creation of coke and the purification of gas are performed completely automated.

Coke makers use a mix of coal to improve the quality of coke they create. High-quality coal does not generate high pressure on the coke oven, and they also shrink enough so that they are easily removed from the coke oven. The properties of coke are influenced by moisture content and density.

The main use of coke is to make iron. The burning of coal to coke produces carbon monoxide. A touch at the bottom of the furnace allows impurities to flow out of the furnace. This, coupled with the fact that many harmful impurities come from heating the coal is the reason why there is so much pollution that comes from the creation of coke.

What is Coke Oven In Steel Plant?

The main function of Coke Ovens is to convert coal into coke which is used as a fuel and reducing agent in the Blast Furnace. Its secondary function is to recover Volatile Matter and CO (Coke Oven) gas from coal and extract chemicals known as Coal Chemicals. CO gas produced is used for heating purposes in the plant.

History of Butterfly Valves

One of the first people to use the butterfly valve was Scottish engineer and chemist James Watt. Watt used them as an important hardware element in his steam engine designs in the late 1700s. People did not really begin using butterfly valves in earnest, though, until the 1870s, when engineers used them as a part of a device with which they controlled air and steam flow to fans and turbines.

As time went on, manufacturers were able to make butterfly valves that were smaller, lighter, more powerful, and more heat resistant. One of the most important changes for butterfly valves came after World War II, when engineers started manufacturing them with seal accessories. These seals were made from synthetic rubbers. With them, butterfly valves became suitable for a much wider range of applications.

Then, in 1969, an American named James E. Hemphill received a patent for an updated butterfly valve design. His design allowed operators to reduce the amount of hydrodynamic torque they used to shift the valve output.
