The choice of process system for gas or liquid treatment or dehydration is very wide, with a high degree of overlap between process applications. This makes the choice of the optimum process route particularly difficult, and is where Petreco/KCC's expertise can ensure the correct solution is selected. Applications include all types of onshore and fxied and floating offshore installations. Equipment is typically supplied skid-mounted with all control, and safety systems integrated. Larger systems can include several modular sub-assemblies together with interconnecting piping for simple on site installation. The diagram above represents the KCC Gas Processing product line.

KCCTM Amine Gas Treating Plants Gas Sweetening Systems with Specialty Amines Gas sweetening - the removal of acidic components such as Hydrogen Sulphide (H2S) or Carbon Dioxide (CO2) - can be achieved in a number of ways. The most commonly used process, however, is a liquid solvent absorption system using one of the specialty amines. These are cost effective when looking at removal of anything from a few hundred PPM to over 50% by volume. Typical applications include: MEA for low acid gas partial pressures DEA for general purposes MDEA for selective H2S removal Special Solvents - licensed processes

Molecular Sieve

KCCTM Glycol Gas Dehydration Plants Gas dehydration using glycol is one of the most established and reliable gas processing technologies. TEG is the most common desiccant, although DEG is sometimes used in cold climates or where more widely available. KCC has further developed their glycol unit know-how through the introduction of high performance systems for the offshore and floating production environments. In particular, KCC offers: Proven, compact equipment sizes Reliable FPSO designs Stripping gas reduction and recirculation technology Minimum BTX emissions Low glycol loss solutions KCCTM Molecular Sieve Gas Treatment Plants Molecular sieves are Alumino Silicates, which have a uniform, crystalline structure. It is this structure, which is used to "filter" out molecules of contaminants. The sieves are produced in pellets of different shapes and sizes to suit the application and bed weight. They are also described by the size of the crystalline structure in Angstroms: 3A Used for drying unsaturated hydrocarbons (Ethylene, Propylene) and highly polar compounds (Methanol, Ethanol). 4A Used for general purpose dehydration service and some carbon dioxide applications. 5A Used for natural gas dehydration, Carbon Dioxide, Hydrogen Sulphide and Mercaptan removal. Also for separating N-Paraffins from branched and cyclic hydrocarbons. 13X Used for simultaneous removal of the above contaminants as it has a larger (10A) pore size.

Amine Treating Treating

KCCTM Glycol & Methanol Injection & Recovery Systems For the effective inhibition of hydrate formation, the lowering of the water dewpoint, or the reduction of corrosion in natural gas transmission and treatment systems, injection of Monoethylene Glycol (MEG) or Methanol is most frequently used. At very cold temperatures Methanol is preferred, but MEG has proven more effective than the other glycols for most situations due to its lower viscosity, lower cost, and lower solubility in liquid hydrocarbons. An associated recovery and regeneration process allows the MEG or Methanol to be recirculated.

KCCTM High-Efficiency Gas Scrubbers Whether onshore, offshore, or on a floating production system, the highest standards of performance are demanded from gas scrubbing equipment. Applications include: Compressor Pre and After Scrubbers Pipeline Knock Out Drums Dehydration Plant Inlet Scrubbers Fuel Gas Filter Separators Flash Drums KCC offers a custom designed range of Gas Scrubbers and Filter Separators, tailored to the individual application, to ensure that all contaminants in the inlet gas are separated effectively and prevented from entering the downstream process systems.

Glycol Gas Regeneration

Stripping Gas Recovery

Fuel Gas Conditioning

KCCTM Indirect-Fired Gas Heaters Indirect-Fired Gas Heaters (using water-bath or anti-freeze in cold climates) are commonly used for applications such as: Fuel gas super-heating prior to turbines J-T Heating after pressure reduction Gas heating after low temperature storage Hydrate prevention KCC offers a custom-designed range of water bath heaters, tailored to the individual application, to ensure the fluid (normally gas) is reliably and safely heated to the necessary temperature to meet the downstream process requirements.

Membrane Gas Treating

KCCTM Fuel Gas Conditioning Systems Modern gas turbines require fuel gas to be treated to a high level of purity to ensure that wear and tear on the blades and machine are minimized. KCC offers a custom designed range of fuel gas conditioning systems. These are tailored to the individual application, to ensure the gas purity requirements can be met reliably and consistently. This ensures longer turbine life and lower maintenance requirements. A typical specification involves: Pressure regulation to 300 to 500 Psig (25 to 30 Barg) Total liquids separation and removal Heating and superheating by 68ºF (20ºC) Fine filtration to remove all particles > 5 microns

Deep Cut Refrigeration

KCCTM Stripping Gas Recovery Systems - SGRSTM Offering a way of achieving zero emissions to atmosphere, and up to 99% reduction in the Greenhouse Effect (compared with venting the stripping gas), KCC's unique Stripping Gas Recovery System comes as a complete, skid mounted package, ready to connect to any existing Glycol Dehydration Unit, which consumes stripping gas and discharges it to flare or vent. Using proven components and technology, the SGRS takes the hot, wet vent steam/gas mixture from the existing still column and draws it into a multi-phase compressor to cool and condense the steam while boosting the gas pressure to 30 psig (2 barg) so that it can be recovered and utilized in the fuel gas system. The wet gas is separated in a compact, cyclone gas scrubber, from which cool, liquid free gas passes to the site fuel gas system or, in some cases, it can be suitable for recirculating as stripping gas. Water, which is knocked out in the separator, is sucked via a cooler back to the multi-phase compressor. Surplus water flows from the separator to the site oily water treatment system.

KCCTM Slug Catchers Liquid slugs can occur in oil and gas flowlines, which run over large distances, or operate in the 2-phase "slug flow" regime. They cause both mechanical problems (due to high velocities and momentum) and process problems (increasing liquid levels, causing surges and trips). KCC offers a custom designed range of slug catchers or interceptors, tailored to the individual application to ensure slugs are dealt with effectively, and cause no disturbance to the downstream process systems.

Rundown surge capacity KCCTM Membrane Gas Treatment Units

KCC is licensed by Air Products for the supply of PRISM® membrane systems, worldwide. Principal uses in the natural gas processing industry are for gas dehydration and CO2 removal. A membrane is a selective barrier. This simply means that different gases, vapors, or liquids move through the membrane at different rates. An example of a barrier would be a balloon. Helium passes through a balloon over time, causing the balloon to deflate. Another example of a barrier is a plastic soda bottle. Over time, the CO2 in the soda will pass through the plastic bottle, and the soda will become flat. Membranes use the principle of selective permeation to perform the desired separations. Each gas in a stream that is fed to the membrane has a characteristic permeation rate, which is a function of its ability to diffuse through the membrane wall. Examples of fast gases are oxygen and water vapor, which diffuse quickly through the membrane wall. Examples of slow gases are nitrogen and methane, which stay in the bore of the fiber and pass through the wall of the fiber much more slowly. The fast gases are vented from the membrane at lower pressure. The driving force for the separation is the difference between the partial pressure of a gas on the inside of the hollow fiber and that on the outside. Membranes may be made from polymers, metals, ceramics, glasses, carbon, etc. PRISM membranes are made from polymers.
