Intermediate bulk container

Intermediate bulk container is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Intermediate bulk container rather than just read about it.

Reference excerpt

Intermediate bulk containers (also known as IBCs, IBC totes, or pallet tanks) are industrial-grade containers engineered for the mass handling, transport, and storage of liquids, partial solids, pastes, granular solids or other fluids. The magnitude of size of typically 1000 liter is intermediate between barrel resp. drum and mostly immobile storage tanks or Tank containers moved by trucks and railway. IBCs can be handled by a single person with a pallet jack, and stacked with a fork lift if rigid. The IBC was developed and patented in 1993 by Olivier J. L. D’Hollander, who worked at Dow Corning. There are several types of IBCs with the two main categories being flexible IBCs and rigid IBCs. Many IBCs are reused with proper cleaning and reconditioning or repurposed. IBCs are roughly pallet-sized and either attach to a pallet or have integral pallet handling features. This type of packaging is frequently certified for transporting dangerous goods or hazardous materials. Proper shipment requires the IBC to comply with all applicable regulations.

Types

Rigid IBC

Rigid intermediate bulk containers are a type of bulk box. They can be reusable, versatile containers with an integrated pallet base mount that provides forklift and pallet jack maneuverability. These containers can be made from metal, plastic, or a composite construction of the two materials. Rigid IBC design types are manufactured across a volume range that is in between those of standard shipping drums and intermodal tank containers, hence the title "intermediate" bulk container. In the USA, IBC totes are authorized per Title 49 CFR codes to be fabricated of a volume up to 3 m3 (793 US gal) while maintaining the IBC name and their federal shipping and handling permits. Many rigid IBCs are designed to be stackable. Containers for hazardous and dangerous fluids must carry UN-recognized markings that enable the operator and those handling the container to ensure suitability with the contained cargo and associated handling requirements. IBC tank capacities generally used are often 1,040 and 1,250 L (275 and 330 US gal). Intermediate bulk containers are standardized shipping containers often UN/DOT certified for the transport handling of hazardous and non-hazardous, packing group II and packing group III commodities. Many IBC totes are manufactured according to federal and NSF/ANSI regulations and mandates and are often IMDG approved as well for domestic and maritime transport. Metal alloy IBC tanks are also manufactured according to NFPA and UL142 certification standards for extensive storage of materials labelled as flammable and/or combustible. Intermediate bulk containers can be manufactured from various materials based on the requirements of the application or service the IBC will be used for. Traditional materials include:

Plastic (high-density polyethylene) Composite: galvanized steel and plastic Carbon steel Stainless steel (304 and 316/316L grades)

Collapsible IBC Collapsible IBC tanks are designed so that they can be folded when needed to save space when empty or used for return transport. They can also be stacked to save storage space. The replaceable plastic bags with a typical volume of 500 or 1,000 L (130 or 260 US gal) make the container easy to clean and reuse, which is needed for use with food, as strict hygiene regulations must be observed. The space-saving intermediate bulk containers are used in the pharmaceutical, cosmetics and food industries. Several designed have been developed.

Caged IBC

Caged IBCs are composite structures and are in very common usage. Caged IBCs are often utilized as one-use containers, especially when it comes to hazardous materials, but are also suitable for cleaning and reuse under many conditions. This IBC type often features an interior liner, blow-mold manufactured from polyethylene, that is structurally supported by a protective cage frame, often of galvanized steel composition. Caged IBCs are engineered for the bulk handling of liquids, semi-solids, as well as solid materials. All materials can present certain safety and compatibility concerns, especially hazardous liquids, and proper guidance is always recommended whenever using caged IBC totes for harsh chemicals. Caged IBC totes are thermoplastic blow-mold engineered, often, from virgin high-density polyethylene (HDPE), a BPA-free, strong plastic. Caged tote engineering is a top port inlet with cap for filling of cargo, typically 150 or 225 mm (5.9 or 8.9 in) with a bottom discharge outlet port, typically 50 mm (2.0 in) ball valves, and an integrated pallet base skid for maneuvering the IBC. The pallet base of composite IBCs often features four-way access channels for universal handling by moving equipment such as forklifts and pallet jacks. Caged IBC engineering has been able to produce a multi-industry use container that is mobile, convenient, consistent, durable, as well as compatible. The high-density polyethylene used in the construction of rigid, poly caged IBC totes is a durable thermoplastic chosen for its compatibility with many chemicals and materials often employed throughout industries, commercial applications, agriculture as well as consumer-based uses, as caged IBCs are often repurposed for aquaponic gardening. Caged intermediate bulk containers are standardized for manufacture to near a commonly accepted pallet size. Caged IBCs are often 1,200 by 1,000 by 1,150 mm (47 by 39 by 45 in) for 1,000 litres (260 US gal) and 1,200 by 1,000 by 1,350 mm (47 by 39 by 53 in) for 1,250 L (330 US gal), where both volume types are available in either new, rebottled, or reconditioned model types, where: rebottled means a brand new HDPE liner in a previously used but certified steel cage, and; reconditioned means a previously used but cleaned and certified HDPE liner and cage.

Flexible IBC - big bag

A standard flexible intermediate bulk container can hold 500 to 1,000 kg (1,100 to 2,200 lb) and manufacturers offer bags with a volume of 285–2,830 L (10–100 cu ft). Flexible intermediate bulk containers are made of woven polyethylene or polypropylene or other heavy polymers. Bags are designed for storing or transporting dry, flowable products, such as sand, fertilizer, and plastic granules. They typically have lifting straps but are frequently handled on a pallet.

Worked examples

Example 1 — a first encounter with Intermediate bulk container

Start with the simplest possible case. Write down what Intermediate bulk container claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Intermediate bulk container before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Intermediate bulk container ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Intermediate bulk container

In research: Intermediate bulk container appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Intermediate bulk container in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Intermediate bulk container is common in secondary-school and first-year university syllabi. It links to neighbouring topics Mechanical standards, Packaging, Shipping containers, so understanding it makes those chapters shorter.
In everyday life: Look for Intermediate bulk container outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
