LEVEL AND FLOW INSTRUMENTS FOR MODULAR SKID SYSTEMS

Throughout the process industry, modular fabrication has increasingly become a viable option to field construction for owner/operators, OEMs, and plant engineers. From zero site disruption during fabrication to plug-and-play commissioning, single- and multiple-skid systems have become popular options in recent years. Nearly any unit operation can be fabricated as a self-contained, modular skid system. While most skids are housed within an open structural framework, a skid maker can fabricate the skid system inside a standard shipping container. In the pages ahead, we feature 12 process operations...

Ammonia Skid Anhydrous and aqueous ammonia are skid-configured for unloading, storage, transfer, vaporization, stripping, metering, injection, and urea-to-ammonia (U2A) conversion. Skids range from compact, single-process systems to multi-unit utility systems. Featured Application: Aqueous Ammonia Vaporization Ammonia vaporization changes the state of ammonia from a liquid to a gas. Vaporized ammonia is important for use in industrial refrigeration and in pollution abatement technology, such as selective catalytic reduction (SCR) systems used to neutralize nitrogen oxides from large electric...

Biomass Gasifier Skid Biomass is cultivated and waste forms of biological material, including: crops, forest residue, waste from livestock, food processing, and municipal sources. When biomass is heated in the absence of oxygen, it decomposes into a mixture of hydrogen and carbon monoxide gases known as synthesis gas or ‘syngas.’ Like natural gas, syngas is a valuable energy asset that can fuel boilers, generators, and furnaces, or serve as a feedstock. Biomass-to-Syngas Skid Featured Skid Configuration: BioMass-to-Syngas Skid In this entrained-flow type of gasifier, the steam and oxygen reactants...

Blending & Batching Skid Blending & batching skids are used in all forms of liquids processing. The largest users are food & beverage, chemical, petrochemical, pharmaceutical, and paints & coatings industries. ‘Blending’ refers to the in-line combining of ingredients into a single output stream. ‘Batching’ is the dispensing of controlled quantities of process fluids into one or more vessels. Featured Skid Application: Soft Drink Blending & Batching Skid Nearly 35 billion gallons of soft drinks and allied products are consumed annually. Blending and batching units that combine ingredients to produce...

Clean-In-Place Skid Clean-in-Place (CIP) is a method of cleaning the interior surfaces of pipes, vessels, process equipment, filters, and associated fittings without disassembly. Industries that rely heavily on CIP are those requiring the highest levels of hygiene, and include: dairy, beverage, brewing, processed foods, pharmaceutical & biotech, and cosmetics. Featured Skid Application: Pharmaceutical CIP/SIP Skid CIP skids clean and sterilize process systems to the highest hygienic standards. A Sterilization-in-Place (SIP) process (attained by steam, hot water, or chemical means) is typically...

Filtration Skid Filtration is the process of removing contaminating components from process media. Filtered media include air, steam, compressed air, gas, and liquids in a broad range of viscosities. Liquids commonly filtered include water, solvents, heat transfer fluids, hydrocarbons, paints and coatings, pulp slurry, beverages, pharmaceuticals, edible oils, food products, fuels, and lubrication oils. Featured Skid Application: Fuel & Oil Filtration Hydraulic oil, turbine oil, lubrication oil, gear oil, transformer oil, and diesel fuel are commonly filtered. Maintaining fluid cleanliness increases...

Gas Compression Skid Gas compressors are used wherever higher pressures or lower volumes of a gas are required, including: natural gas pipeline transport, refrigeration, combustion air, gaseous fuels, and process gas compression. Gas compression systems are typically used in petroleum refineries, natural gas plants, petrochemical plants, and chemical facilities. Featured Skid Application: Gas Compression Skid Commonly found in power generating, steel making, and boiler plants, this compression system increases the pressure of the fuel gas to a level suitable for optimum combustion in a gas turbine,...

Liquid Separation Skid Separation is essential to all processing industries. Skids vary according to the separation technology, including: distillation, gravity separation, coalescence, crystallization, adsorption, membrane processes, absorption, and extraction. Pre-separated mixtures can combine two or more states: solid-solid, solid-liquid, solid-gas, liquid-liquid, liquid-gas, gas-gas, or solidliquid-gas mixtures. Featured Skid Application: Oil-Water Separation An oil-water separator is designed to separate oil and suspended solids from the wastewater effluents in chemical and petrochemical...

Natural Gas Dehydration Skid Water vapor is the most common undesirable impurity found in natural gas. The problem of gas hydrate formation results in ice-like hydrates plugging flow lines and natural gas processing equipment to cause severe operational problems. Two methods employed for gas dehydration are expansion refrigeration, or absorption through the use of solid or liquid desiccants. Featured Skid Application: Glycol Dehydration Skid The use of ethylene glycol liquid desiccants is one of the most established and reliable techniques for natural gas dehydration. Liquid desiccants include...

Pump Skid Pump skids for fluid transfer are often found in field and factory processes. Pump skids move a broad range of fluids: from asphalt, cement slurries and drilling mud to potable water, hot condensate and every imaginable liquid chemical. Pump skids typically range from 10 HP electric-powered units to 1500 HP diesel skids with multiple pumps. Featured Application: Condensate Recovery Pump Skid Because condensate leaving a steam trap retains up to 25% of its original heat energy, recovery and utilization of condensate reduces feedwater makeup, fuel, and water treatment costs. Pumping is...
