Glycol Reboilers

Lean, water-free glycol (purity >99%) is fed to the top of an absorber where it is contacted with the wet natural gas stream. The glycol removes water from the natural gas by physical absorption and is carried out the bottom of the column. Upon exiting the absorber the glycol stream is often referred t... read more

Catalyst Regeneration

The Continuous Catalyst Regeneration (CCR) process is part of a process used in the petroleum and petrochemical industries, which produces aromatics from naphthenes and parafins commonly used as motor fuel. In this process (Figure 1), hydrotreated naptha is combined with recycled hydrogen gas, h... read more

Fuel Gas

Fuel gas is commonly used in the power generating industry as an energy source for turbines. Before the fuel gas is burned in the turbines it needs to be treated to ensure the removal solid, liquid and gas contaminants. A fuel gas conditioning system commonly consists of the following components, a pre heater, a pressure regulation valve, two high efficiency coalesc... read more

Natural Gas

Natural gas is transmitted through long distance pipe lines under high pressure. However, this pressure is not suitable for local gas distribution networks supplying customers for use in domestic and industrial gas appliances. Usually, a pressure reduction valve (PRV) ie a throttle valve (also known as Joule-Thompson valve) is used at a Pressure Reduction S... read more

Molecular Sieve Regeneration

A molecular sieve is a material containing tiny pores of a precise and uniform size that is used as an adsorbent for gases and liquids.

Molecules small enough to pass through the pores are adsorbed while larger molecules are not. It is different from a common filter in that it operates on... read more

Heating Medium

Heating medium is any solid or fluid (such as water, steam, air, or flue gas) which is used to convey heat from a heat source (such as an electric immersion heater) to a process or space being heated. Electric heat is often used as a temporary or permanent solution to the heat the medium which is then used in various types of heat exchangers throug... read more

Crude Oil

Heavy crude oil or Extra Heavy Crude oil is any type of crude oil which does not flow easily. It is referred to as "heavy" because its density or specific gravity is higher than of light crude oil. Heavy crude oil has been defined as any liquid petroleum with an API gravity less than 20°, meaning that its specific gravity is greater than 0.9... read more

KO Drums

A vapor-liquid separator is a vertical vessel used in several industrial applications to separate a vapor-liquid mixture. Gravity causes the liquid to settle to the bottom of the vessel, where it is withdrawn. The vapor travels upward at a design velocity which minimizes the entrainment of any liquid droplets in the vapor as it exits the top of the ve... read more

Seal Gas

Dry gas seals are used in process gas centrifugal compressors. It is necessary to have shaft sealing to prevent the process gas from escaping to atmosphere. Dry gas seals can be applied to accomplish the required shaft sealing. Dry gas seals are available in a variety of configurations but a tandem style seal is typically ap... read more
