In steam reforming ammonia plants there is a surplus of high-level heat that is produced in primary reforming, secondary reforming, shift conversion and ammonia synthesis. Most of the waste heat is recovered for producing high pressure steam that is used in turbines for driving compressors, pumps and fans.
Brad Seibel. Octopuses, squids, and similar animals are members of a group of ocean invertebrates (animals with no backbone) called cephalopods. Cephalopods are a kind of mollusk, a group of animals that also includes clams, oysters, and snails.

The bones of tetrapods, or vertebrates with legs, are homologous in the forelimb. The bones in the wing of a bird, the hand of a primate, the paw of a cat and the flipper of a dolphin are all different in function, but are very similar and have evolved from a common ancestral structure.
